A quick detailer with an acidic Kalk-EX formula (pH 2.5) that dissolves limescale, water spots and mineral residue on paint, glass and plastic in a single step while sealing at the same time with a polymer wax.

The acidic formula at pH 2.5 neutralises alkaline lime compounds through a direct acid-base reaction, while an included polymer wax leaves gloss and a light protective film behind at the same time — both in one single pass on paint, glass and plastic.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-finish-spray-exterior-fse-quick-detailer-kalk-ex_hero.png?v=1776464165\" alt=\"Koch-Chemie FSE Finish Spray Exterior quick detailer with Kalk-EX\" loading=\"lazy\" width=\"1200\" height=\"900\"\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKalk-EX dissolves mineral deposits chemically.\u003c\/strong\u003e The pH value of 2.5 neutralises alkaline lime — limescale lets go without any mechanical scrubbing. 30–60 seconds of dwell time on stubborn spots is enough before you go in with the microfibre cloth. A plain wipe with no acidic component just moves the lime around; the FSE actually dissolves it.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree jobs, one step.\u003c\/strong\u003e The Koch-Chemie FSE cleans, conditions and protects all at once.

Don't use it on acid-sensitive materials such as certain matte paints, on freshly waxed or ceramic-coated vehicles, or on surfaces that have been sitting in direct sun. Check the temperature before you start.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e Using FSE after waxing is the most common mistake. The pH of 2.5 doesn't only dissolve lime — it also eats into waxes and polymer sealants. Right order: apply FSE on the lime spots first, buff dry, then wax or sealant. Run the FSE as your everyday quick detailer on freshly sealed paint and you're actively stripping your LSP. Hardly any shop tells you that.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eUsing the Koch-Chemie FSE on a cool surface\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie Finish Spray Exterior only works reliably on cool, dry surfaces. On hot metal after direct sun the spray flashes off too quickly and leaves residue instead of removing it. Pull the car into the shade first and give it five minutes. If the surface still feels clearly warm to the touch, don't start yet.\u003c\/p\u003e\n\n\u003cp\u003eSpray it straight onto the surface or into the microfibre cloth — 2–3 pulls per panel either way. The FSE ships without a trigger head; a pressure sprayer like the Canyon CHS-3AN (available as a bundle option) makes the application more even and stops you over-dosing. Work it in with a soft \u003ca href=\"\/en\/collections\/mikrofasertuecher\"\u003emicrofibre cloth\u003c\/a\u003e and buff off with a dry second cloth. The two-cloth method keeps streaks away, because the first cloth picks up dirt and lime while the second one only buffs.\u003c\/p\u003e\n\n\u003cp\u003eOn stubborn limescale on glass, let it dwell for 30–60 seconds before you buff. On paint, working it straight in without extra wait time is enough. Glass benefits the most: the FSE pulls water spots off your windows that pH-neutral quick detailers can't shift. Ordinary sprays only move the lime around visually — the acidic Kalk-EX formula breaks the mineral bond down chemically. On the rear window and side glass the method works exactly as it does on the windscreen.\u003c\/p\u003e\n\n\u003cp\u003eIf you wash in regions with very hard water, you know the problem: even after careful drying, fine lime residue stays behind. That's when the FSE belongs straight into your routine after drying off — one shot onto the still slightly damp cloth covers whole panels. That stops lime from baking in and having to be removed the hard way later. On black and dark paint you spot lime residue instantly — that's where it pays to do it after every wash.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-finish-spray-exterior-fse-quick-detailer-kalk-ex_anwendung.png?v=1776464226\" alt=\"Koch-Chemie FSE applied to car paint with a microfibre cloth\" loading=\"lazy\" width=\"1200\" height=\"900\"\u003e\n\n\u003ch3\u003eIt dissolves lime. Your coating too.\u003c\/h3\u003e\n\u003cp\u003eOn vehicles with no active protective sealant, the Koch-Chemie FSE quick detailer is the right product: it dissolves limescale, water spots and mineral deposits on unsealed paint, glass and plastic and leaves gloss behind. That's its strong suit and the reason detailers and detailing shops keep it close.\u003c\/p\u003e\n\n\u003cp\u003eOn vehicles with a ceramic coating or a long-life nano coating it's a different story. The pH of 2.5 can attack the cross-link structure of SiO₂-based coatings and cut their lifespan right down. If you're looking after an active ceramic coating, reach for a pH-neutral \u003ca href=\"\/en\/collections\/quick-detailer\"\u003ecoating-safe quick detailer\u003c\/a\u003e instead. If you only have wax protection or no sealant at all: the FSE is the faster and more effective answer than a pH-neutral spray that doesn't dissolve lime but only moves it around.\u003c\/p\u003e\n\n\u003cp\u003eTwo more limits of the FSE: tar, bitumen spots and bug splatter don't react to acidic chemistry — for those you need a solvent-based product. And on baked-in limescale that has already etched into the clear coat, the FSE hits its ceiling.\u003c\/p\u003e\n\n\u003cp\u003eIt dissolves fresh mineral deposits reliably, but not paint damage from lime that has been left to sit too long. In that case you need a light polish first to fix the damage. After that the FSE protects reliably against new deposits during ongoing maintenance.\u003c\/p\u003e\n\n\u003cp\u003eIf you're not sure whether your car has a sealant: water beading on the paint after rain is a good sign of an active LSP. In that case work with a pH-neutral quick detailer and use the FSE only on lime spots on glass or plastic, where coatings are rarely applied.\u003c\/p\u003e\n\n\u003cblockquote\u003e\n  \u003cp\u003e“Great product.

If you live in a region with very hard water and wash your car yourself a lot, you'll find in the FSE a tool that pH-neutral quick detailers simply can't replace.\u003c\/p\u003e\n\n\u003cp\u003eIn a detailing business the FSE is a classic for the final wipe-down after a full detail: sprayed on fast, buffed off straight away, high gloss done. The 10-litre and 200-litre containers make cost-effective bulk use possible. At a normal dose of 2–3 pulls per panel, 1 litre covers around 40–60 applications on a mid-size car — that works out to well under 30 cents per application. For shops detailing 10 to 20 cars a day, the 200-litre drum is the most economical option.\u003c\/p\u003e\n\n\u003cp\u003eThe FSE is less suited to vehicle owners with a ceramic coating or fresh wax protection who want a general-purpose care quick detailer. And anyone who mainly needs to remove tar or bug splatter comes up empty here too — the FSE isn't an all-purpose cleaner, it's a lime specialist with a conditioning effect.\u003c\/p\u003e\n\n\u003cp\u003eTo round out the lime workflow we suggest a top-up wax or a \u003ca href=\"\/en\/collections\/spruhversiegelung\"\u003espray sealant\u003c\/a\u003e after the FSE pass, if the car has no active LSP. The FSE cleans and leaves a light polymer protection behind, but it doesn't replace a full seal. If you want more durability after the lime treatment, finish the workflow with a spray sealant — the surface is then not just lime-free but protected too.\u003c\/p\u003e\n\n\u003cp\u003eThe Detailing1 insight: plenty of quick detailers promise limescale removal but only deliver a pH-neutral gloss film that visually masks the lime. The FSE is one of the few quick detailers on the German market that uses real acid-base chemistry at pH 2.5 to remove lime. The difference is visible: on heavily limed-up glass the FSE dissolves water spots in one pass that other sprays need three or four goes at. That's not a marketing claim, it's chemistry.\u003c\/p\u003e\n\n\u003cp\u003eIf you're choosing between the Koch-Chemie FSE and the \u003ca href=\"\/en\/products\/koch-chemie-quick-finish-qf-quick-detailer\"\u003eKoch-Chemie Quick Finish QF\u003c\/a\u003e: the QF is pH-neutral and coating-safe, made for vehicles with active protection. The FSE is the right pick when limescale is the main problem and there's no active coating. Lime: FSE. Coating: QF. Both products have their place — it's about the right job, not the better product.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-finish-spray-exterior-fse-quick-detailer-kalk-ex_lineup.png?v=1776464385\" alt=\"Koch-Chemie FSE all sizes 1L 10L variant overview\" loading=\"lazy\" width=\"1200\" height=\"900\"\u003e\n","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48484526817615,"sku":"D1-KCX-285001","price":11.99,"currency_code":"EUR","in_stock":true},{"title":"1 liter + Canyon spray head CHS-3AN","offer_id":49062963347791,"sku":"D1-KCX-68549+CHS-3AN","price":15.82,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml","offer_id":49671582056783,"sku":"D1-KCX-285001_2","price":23.5,"currency_code":"EUR","in_stock":true},{"title":"3x 1000 ml","offer_id":49671582089551,"sku":"D1-KCX-285001_3","price":34.89,"currency_code":"EUR","in_stock":true},{"title":"10 liters","offer_id":48484526850383,"sku":"D1-KCX-285010","price":100.49,"currency_code":"EUR","in_stock":true},{"title":"200 liters","offer_id":49602838397263,"sku":"D1-KCX-285200","price":2020.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-finish-spray-exterior-fse-quick-detailer-kalk-ex.jpg?v=1710627039"},{"product_id":"koch-chemie-magic-wheel-cleaner-mwc-felgenreiniger","title":"Magic Wheel Cleaner \"Mwc\" Wheel Cleaner","description":"\u003ch2 id=\"speakable-headline\"\u003eDissolve brake dust chemically on polished wheels\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Magic Wheel Cleaner? An acid-free, viscous wheel cleaner from Koch-Chemie's workshop line that visibly dissolves brake dust and flash rust chemically via a red-violet colour change. Works on alloy painted, alloy polished, chrome and steel.

The active ingredient ammonium mercaptoacetate, a salt of thioglycolic acid, reacts with the iron(III) compounds in brake dust and lifts them off the wheel surface as a red-violet complex. The colour change isn't a marketing gimmick but the chemical reaction itself: where you see violet, iron is being converted right then and there. With a pH of 5–6 the formula stays gentle on painted and polished alloy wheels, chrome and steel. The high viscosity of 50 mPa·s means the product clings to vertical wheel faces instead of running straight off — so you get the full dwell time on the surface.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRed-violet colour change as a reaction indicator.\u003c\/strong\u003e No guessing how long to wait.

On anodised or matte-coated wheels, test on a hidden spot first.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e Always spray onto a cold, dry wheel — never in direct sun, never onto warm brakes after a drive. Warm surfaces let the gel dry on, and that leaves residue you then have to brush off. On heavily soiled wheels after months without cleaning, two short passes beat one long one: the active ingredient is chemically saturated after about 5 minutes. Just let it dwell twice for 3 minutes each and rinse in between.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCold wheel. Spray. Wait 2 to 5 minutes.\u003c\/h3\u003e\n\u003cp\u003eSpray the Magic Wheel Cleaner onto the cold, dry wheel — cover spokes, barrel, the rim edge and the wheel bolts evenly. Thanks to the syrup-like consistency the product clings vertically without you having to change how you work. Best to work bottom to top so you don't cover faces you've already wetted.\u003c\/p\u003e\n\n\u003cp\u003eAfter 30 to 60 seconds the colour change kicks in: first on spots with a lot of brake dust, then across the whole face. Red-violet streaks show you exactly where iron particles are being converted. After 2 to 5 minutes' dwell time the reaction is done — waiting longer gets you nothing, because the active ingredient is saturated after about 5 minutes. A common mistake is leaving the product on for 10 minutes hoping for better results. The opposite happens: the solution starts to dry on and leaves streaks.\u003c\/p\u003e\n\n\u003cp\u003eFinish by rinsing off with a strong jet of water from the pressure washer or garden hose, top to bottom. With heavy brake dust between tight spokes a \u003ca href=\"\/en\/collections\/zubehoer-felgenpflege\"\u003ewheel brush\u003c\/a\u003e can help spread the dissolved material — but not for scrubbing, just for touch-up. If you clean weekly to fortnightly, one pass usually does the job.\u003c\/p\u003e\n\n\u003cp\u003eA note on dosing: 500 ml lasts for about 10 full vehicle cleans. Per wheel, 40 to 50 ml is plenty. That works out to EUR 1.25 per full application — far more economical than the bottle price suggests, once you weigh it against the time spent mechanically scrubbing with less effective cleaners.\u003c\/p\u003e\n\n\u003ch3\u003eIt dissolves iron particles. Not tar.\u003c\/h3\u003e\n\u003cp\u003eThe Magic Wheel Cleaner is built precisely for one job: dissolving brake dust and flash rust chemically. The reaction between ammonium mercaptoacetate and the iron(III) ions in brake dust is the mechanism — anything that isn't iron doesn't get touched. That explains the colour change as a diagnostic tool: no colour means no iron, and no effect in that case isn't a shortfall of the product but the right answer to the dirt.\u003c\/p\u003e\n\n\u003cp\u003eAs a secondary use, the Magic Wheel Cleaner also works on paint as a flash-rust remover — especially handy on vehicles parked under industrial fallout or next to railway tracks. Fine iron particles settle there on the clear coat and react with the MWC formula just like they do on the wheel. Used before polishing, it boosts the adhesion of any following wax or ceramic coating, because the paint surface is genuinely contamination-free.\u003c\/p\u003e\n\n\u003cp\u003eWhere the MWC isn't the right product: baked-on tar, bitumen spots and oily soiling don't react with thioglycolate salts. For that you need a solvent-based tar remover. On badly neglected wheels with months-old brake dust that has worked its way into the pores, the stronger \u003ca href=\"\/en\/products\/koch-chemie-reactive-wheel-cleaner-rwc\"\u003eKoch-Chemie Reactive Wheel Cleaner\u003c\/a\u003e can be the better call — its acid system is more powerful, though not suited to every wheel material. The choice is clear: when safety on chrome and polished wheels matters, MWC. When you need maximum cleaning power and you're working with alloy painted and steel, RWC.\u003c\/p\u003e\n\n\u003cp\u003eA second case where no wheel cleaner in the world will help anymore: when the wheel is already visibly corroded or the clear coat has flaked off. At that point cleaning isn't the issue anymore — paint refurbishment is. The Magic Wheel Cleaner is a care product, not a restoration product.\u003c\/p\u003e\n\n\u003ch3\u003eYour standard for the regular wheel workflow\u003c\/h3\u003e\n\u003cp\u003eThe Magic Wheel Cleaner is the right call for anyone who keeps their wheels on a regular schedule and wants a product where they don't have to think about material compatibility. One product, one step, all wheels done. That's workshop logic — and that's exactly what the MWC is formulated for.\u003c\/p\u003e\n\n\u003cp\u003eIt really plays its strengths when you look after several vehicles with different wheel types or work on a fleet. Instead of three cleaners for three wheel types, one does it. It's weaker on extremely baked-on brake-dust residue from high-performance brake setups, or on wheels that haven't been cleaned for months. In both cases a second pass or a more aggressive product makes more sense than extending the dwell time.\u003c\/p\u003e\n\n\u003cp\u003eAs a complete solution the Magic Wheel Cleaner works best paired with a \u003ca href=\"\/en\/collections\/vorreinigung\"\u003epre-cleaner\u003c\/a\u003e like Koch-Chemie Vorreiniger B, applied as foam over the whole wheel before the MWC goes into the spokes. Finish with a \u003ca href=\"\/en\/collections\/reifenpflege\"\u003etyre dressing\u003c\/a\u003e on the flank — and the complete wheel workflow comes in at around 15 minutes per vehicle, if you stay on it every two weeks. That's the most common combo our customers buy: Vorreiniger B + Magic Wheel Cleaner. A precise, repeatable routine that works without scrubbing.\u003c\/p\u003e\n\n\u003cp\u003eHead to head with the acid-free classic SONAX FelgenBeast, the Magic Wheel Cleaner comes out ahead on two counts: the higher viscosity means longer contact time on the wheel, and the workshop formula is dosed stronger for commercial use. The FelgenBeast has a milder smell, though — if you work in a closed garage you'll definitely notice that. The Magic Wheel Cleaner is the workshop standard. The FelgenBeast is the garage all-rounder. Both do their job reliably; the question is which one fits your working environment.\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"500 ml","offer_id":48503670374735,"sku":"D1-KCX-425500","price":13.49,"currency_code":"EUR","in_stock":true},{"title":"2x 500 ml","offer_id":49725159276879,"sku":"D1-KCX-425500_2","price":29.38,"currency_code":"EUR","in_stock":true},{"title":"3x 500 ml","offer_id":49725159342415,"sku":"D1-KCX-425500_3","price":43.62,"currency_code":"EUR","in_stock":true},{"title":"10 liters","offer_id":48503670407503,"sku":"D1-KCX-425010","price":123.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-magic-wheel-cleaner-saeurefreier-felgenreiniger.jpg?v=1776410618"},{"product_id":"koch-chemie-allround-surface-cleaner-asc-allzweckreiniger","title":"Allround Surface Cleaner \"Asc\" All-Purpose Cleaner","description":"\u003ch2\u003eReady-to-use and streak-free through the cabin with the Koch-Chemie Allround Surface Cleaner\u003c\/h2\u003e\n\n\u003cblockquote\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Allround Surface Cleaner?

The mist from the spray bottle works its way into display edges, button gaps and speaker grilles, where it settles as a fine film you won't get back out later. Instead, lay down 2–3 squirts on the folded face of your microfibre cloth and work from there onto the surface. Only on big, closed panels like door cards or the headliner do you spray straight onto the part — there the mist doesn't matter.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray, wait 30 seconds, microfibre after\u003c\/h3\u003e\n\u003cp\u003eYou spray the Koch-Chemie Allround Surface Cleaner undiluted onto the surface from about 10–15 cm, let it dwell for 15–30 seconds and wipe down with a clean microfibre cloth. That's all the prep it takes.\u003c\/p\u003e\n\n\u003cp\u003eOn bigger panels like the dashboard, door cards or headliner, three to five squirts per part is plenty. Give the cleaner a moment to break down skin oils, fingerprints and the dust-binding layer, then wipe down evenly with the dry side of your cloth. For vents, buttons and trim strips you spray onto the cloth first and work from there into the edges.\u003c\/p\u003e\n\n\u003cp\u003eTreat the headliner with extra care: only dampen the cloth, never spray the part directly. The headliner fabric mustn't get soaked, or the adhesive underneath lets go. With the ASC you work in broad, long passes so no dry edges form between the damp and the untreated areas.\u003c\/p\u003e\n\n\u003cp\u003eA common mistake is too much product and too long a dwell time. When the ASC flashes off, fine streaks stay behind that you then have to re-wet and wipe away — an avoidable extra round. So work panel by panel rather than across the whole surface, and keep the dwell time under a minute.\u003c\/p\u003e\n\n\u003cp\u003eWith a cleaning gun like the Tornador or Cyclone you can also work the ASC into textiles, seat seams and door pockets, where the cloth alone won't reach. The pH-neutral formula is built for it: it lifts the dirt into foam and picks back up with little residue. With the gun method, follow up afterwards with compressed air or a thirsty cloth so no moisture stays trapped in the part.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/asc_2_anwendung.jpg?v=1775896038\" alt=\"ASC sprayed onto a microfibre cloth in front of a car interior\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eStrengths and limits of the ASC day-to-day\u003c\/h3\u003e\n\u003cp\u003eThe ASC is pH-neutral and ready-to-use.

That's deliberate in the formula, not a shortfall.\u003c\/p\u003e\n\n\u003cp\u003eOn typical everyday dirt the Allround Surface Cleaner pulls its weight: skin oil on the wheel, fingerprints on the touchscreen, a dust film on the centre console, pollen blown into the A-pillar, white specks on black plastic. That's what the product was made for.\u003c\/p\u003e\n\n\u003cp\u003eOn coated leather, piano black and gloss trim the neutral pH is an extra safety net that takes away the material guesswork that always rides along with alkaline interior cleaners. You don't have to think before every use about whether the product suits the material — on normal plastic, glass and leather surfaces in the car the ASC is a safe call.\u003c\/p\u003e\n\n\u003cp\u003eWhat the ASC won't do: it won't shift old nicotine films, an oily workshop grip on the door frame or coffee stains baked into the fabric. Badly yellowed plastics on the sill or a dried cola splash in the cup holder need more muscle too.

A full interior detail on a passenger car burns through 80 to 150 ml of product. So the 10-litre canister is good for around 60 to 120 full details, depending on how dirty the cars are and how you work.\u003c\/p\u003e\n\n\u003cp\u003eThe ASC is less of a fit when you're mainly dealing with extreme cases — smoker cars, mouldy seats, dried coffee on microfibre seat covers, paint and grease splatter out of the service bay.

Its mix of anionic and nonionic surfactants emulsifies dirt without going after the wax or sealant film already on the paint. The formula is completely free of phosphates and NTA and is cleared for biological greywater treatment plants, which is exactly why you'll find it in hobby wash bays as well as in larger gantry washes and tunnel washes.\u003c\/p\u003e\n\n\u003cp\u003eThe pH 9 profile is the core design trade-off: strong enough to break down baked-on road film and pollen, mild enough to keep your typical carnauba waxes and paint sealants alive through a normal wash season.

Work in full sun and let the foam dry on, and you'll pull water spots and streaks onto the paint, which happens with any shampoo, not just As.

For dirtier cars after a long motorway run or van use, step up to 1:10 (around 100 ml in 10 litres); for cars parked outside all the time with baked-on pollen and bird mess, go to 1:5 (200 ml in 10 litres).

Rs has a pH-neutral character and contains polymers that bond to the coating's SiO₂ structure and rebuild the hydrophobic beading. For a plain wash with no coating involved, Rs makes no sense, the extra cost per litre only pays off when a coating actually exists.\u003c\/p\u003e\n\n\u003cp\u003eThe Ceramic Effect Shampoo \"Ces\" is the premium option with an extra SiO₂ boost; it brings a mini coating refresh to every wash and suits cars with no permanent coating that should still show hydrophobic behaviour between detailing sessions.

Spray straight onto the glass towel, not the panel, so you don't fling drops onto the dashboard or door card. Neat is also the move for the inside of the windshield, where outgassed plastics build a paper-thin film that diluted mix only half-dissolves. You spot that layer by the streaky glare in backlight even after you've just cleaned.\u003c\/p\u003e\n\n\u003cp\u003eDilution mistake we see often: concentrate first into the empty bottle, then water — that order builds a foam crown you'll be rinsing for minutes.

So Glas Star handles both inside and outside glass — most interior-only cleaners can't say the same.\u003c\/p\u003e\n\n\u003cp\u003eOn the inside of the rear screen, most cleaners struggle because the embedded heating elements act like edges. Glas Star runs smoothly over the wires thanks to the glide aid and won't streak there — as long as you wipe in one direction with a \u003ca href=\"\/en\/products\/koch-chemie-pro-glass-towel-230gsm-mikrofaser-glastuch\"\u003eglass-specific microfibre\u003c\/a\u003e, not in circles.

Cut to at least 1:3 and keep clear of the edges. On anti-fog coated interior glass (some OEM windshields from 2020 onward), neat Glas Star can streak — patch-test on a 5×5 cm spot first.

Mix once, store the spray bottle frost-free in the garage, and your interior cleans for the next season are queued up.

With fresh air on, the blower pulls dust out of the engine bay onto the glass while you're wiping — streaks are basically guaranteed.\u003c\/p\u003e\n\n\u003cp\u003ePros also flip the sun visors down, because an astonishing amount of spray ends up on them. When you're done and drive off, it runs back onto the freshly cleaned screen as drops. Neither trick lives in any data sheet, but they're the difference between \"okay clean\" and \"looks like a fresh hand-over.\"\u003c\/p\u003e\n\n\u003cp\u003eIf you work with the concentrate regularly, after a few months you build your own system: one dedicated spray bottle at one fixed ratio, a glass-only towel that never touches cockpit or paint, and a second towel for the dry-off.

So the 1 L canister covers one to two years of regular care, while the 10 L canister is the trade standard for workshops and fleets. That works out to about EUR 0.35 in material per set of mats from the 1 L container — and a fair bit less from the 10 L canister.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e The most common mistake with Gummifix is laying it on too thick. The product doesn't soak into the surface like a coating, it dries on top — too much material means a greasy film instead of satin depth. Spray on a thin mist, spread it evenly with a microfibre cloth, and let it flash off completely for at least 30 minutes before the mats go back in the car. Put the mats in wet and you get exactly the slippery surface that going silicone-free was meant to avoid.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eClean mat. Thin coat. 30 minutes to dry.\u003c\/h3\u003e\n\u003cp\u003eYou spray Gummifix onto the clean, dry surface or wipe it on with a sponge — not onto wet or freshly shampooed rubber. Leftover moisture dilutes the product and stops the surface from taking it up evenly.\u003c\/p\u003e\n\n\u003cp\u003eBefore you treat them, the mats come out of the car, get shaken out, degreased with APC or a \u003ca href=\"\/en\/collections\/kunststoffpflege\"\u003eplastic cleaner\u003c\/a\u003e and rinsed clear. Only once the surface is visibly clean and dry does the care make any sense. Eight to ten spray bursts per mat, spread it quickly with a microfibre cloth — with heavy soiling, go twice thin rather than once thick.\u003c\/p\u003e\n\n\u003cp\u003eSame logic for pedal rubbers, just on a smaller scale: three to four bursts per pedal, spread it with a fingertip on the microfibre cloth, let it flash off. Most pedal rubbers have a fine tread that quickly clogs with dust and rubber dust — here Gummifix doesn't just lift the colour, it cleans as you spread it.\u003c\/p\u003e\n\n\u003cp\u003eDrying time is the setting that gets skipped most often. At 20 °C room temperature, full flash-off takes 30 to 60 minutes, quicker in the summer sun, a lot longer in a cold winter garage. Rule of thumb: when the mat doesn't feel damp to the touch and you don't leave a film on your glove, it can go back in the car. When in doubt, air it an hour longer, not five minutes shorter.\u003c\/p\u003e\n\n\u003cp\u003eWorking straight from the 1 L canister does work, but it's too imprecise on fine pedal rubbers or seat consoles. A spray bottle with an adjustable fine-mist head is the difference between dosing and a full bath — pedal rubbers especially are small areas that cop too much product head-on.\u003c\/p\u003e\n\n\u003cp class=\"d1-scene-image\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-gummifix_anwendung.png?v=1776198289\" alt=\"Koch-Chemie Gummifix with a Star spray head being sprayed onto a rubber floor mat\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eMats and pedals yes. Dashboard no.\u003c\/h3\u003e\n\u003cp\u003eThe core job for Gummifix is the horizontal surfaces in the footwell and boot: rubber floor mats, plastic footwells, pedal rubbers, boot liners and sill trims. On these surfaces the satin darkening plays to its strengths — a fresh look without the artificial shine that looks out of place down in the footwell.\u003c\/p\u003e\n\n\u003cp\u003eIt works reliably on rubber seals, door rubbers and boot seals too — it keeps the seals supple and stops them cracking from drying out, especially after UV exposure in the summer. Once a season on the seal rubbers is enough for that; twice a year is plenty for cars that spend a lot of time outdoors.\u003c\/p\u003e\n\n\u003cp\u003eOn tyre sidewalls and outdoor rubber that's permanently weathered, Gummifix isn't your first pick — its life under the weather is around two to three washes, then the care starts to wash off. For tyres there are dedicated tyre dressings with longer staying power and UV protection; for outdoor plastics like bumper add-ons or wheel-arch trims we stock the \u003ca href=\"\/en\/products\/koch-chemie-plast-star-pss-premium-kunststoffpflege-siliconoelfrei\"\u003eKoch-Chemie Plast Star\u003c\/a\u003e — also silicone-oil-free, but with higher weather resistance.\u003c\/p\u003e\n\n\u003cp\u003eWhere Gummifix is the wrong product: glossy dashboards, cockpit plastic on the dash and door cards. There you usually want a light shine, not matte darkening. The \u003ca href=\"\/en\/products\/koch-chemie-top-star-ts-innenraum-kunststoffpflege\"\u003eKoch-Chemie Top Star\u003c\/a\u003e is the alternative for that — same brand, with a satin-gloss finish instead of matte darkening.\u003c\/p\u003e\n\n\u003cp\u003eIf safety on the pedals and mats is your priority, grab the Gummifix. If you want shine on the dashboard, reach for the Top Star. Having both in the garage costs less together than a single shop visit and covers 90 percent of interior care — for the other 10 percent (leather, Alcantara, upholstery) you'll need dedicated products anyway.\u003c\/p\u003e\n\n\u003cp class=\"d1-scene-image\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-gummifix_ergebnis.png?v=1776193282\" alt=\"Floor mat after Koch-Chemie Gummifix treatment in the car footwell\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eGummifix or Gkg or Gkv\u003c\/h3\u003e\n\u003cp\u003eKoch-Chemie has three rubber and plastic care products in the range — same product category, three different jobs. This breakdown saves you the wrong buys we often see in support when customers mix up the three abbreviations.\u003c\/p\u003e\n\n\u003cp\u003eGummifix — abbreviation Guf — is the matte, grippy option for floor mats and pedal rubbers. The Koch-Chemie Gummi- und Kunststoffpflege Gkg produces a clear high gloss and is meant for visible exterior parts like bumper plastic or wheel-arch trims — where you actually want shine. The Gkv is the third tier with an added vinyl component for boat covers, convertible tops and vinyl flooring — more specialised, usually too much product and too pricey per use for everyday cars.\u003c\/p\u003e\n\n\u003cp\u003eOur usage profile from 10 years on the job: Gummifix for everything your shoe touches getting in and out. Gkg for visible exterior plastics that should shine. Gkv for special materials like marine applications. If you only want one product on the shelf and mostly look after the footwell, Gummifix is the right call.\u003c\/p\u003e\n\n\u003cp\u003eThe 1 L canister lasts one to two seasons on one car, the 10 L canister is the trade standard for workshops, dealerships and fleets with 20 to 50 vehicles. Between the two sizes sit the two- and three-packs of the 1 L container, which ease the step up to the 10 L canister price-wise without having to jump straight to a commercial quantity.\u003c\/p\u003e\n\n\u003cp\u003eA Detailing1 insight you won't read from the manufacturer: Gummifix is also the ideal product after an interior clean with steam. After steam cleaning, rubber floor mats are extremely open-pored and take care up especially well — a single thin coat then gives you a depth and staying power that would take three applications without the prep. Steam-clean your mats once a year and care for them straight after, and you'll have mats that still look after three years like they did at six months.\u003c\/p\u003e\n\n\u003cp\u003eThe second insight is about pairing it with how you handle interior textiles: if you've got carpet floor mats in the car and rubber floor mats as a winter set, give the rubber mats one solid treatment with Gummifix in spring before they go down to the cellar. The product stops them drying out and going brittle over the summer — in autumn the mats come back into the car looking like the day you put them away. No chalking, no white haze, no hardened edges.\u003c\/p\u003e\n\n\u003cp class=\"d1-scene-image\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-gummifix_lineup.png?v=1776195721\" alt=\"Koch-Chemie Gummifix 1L bottle and 10L canister side by side\" loading=\"lazy\"\u003e\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48463594979663,"sku":"D1-KCX-48001","price":8.99,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml","offer_id":49723985854799,"sku":"D1-KCX-48001_2","price":17.62,"currency_code":"EUR","in_stock":true},{"title":"3x 1000 ml","offer_id":49723985887567,"sku":"D1-KCX-48001_3","price":26.16,"currency_code":"EUR","in_stock":true},{"title":"10 liters","offer_id":48463595012431,"sku":"D1-KCX-48010","price":69.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-gummifix-gummipflege-kunststoffpflege.jpg?v=1710622833"},{"product_id":"koch-chemie-top-star-ts-innenraum-kunststoffpflege","title":"Top Star \"Ts\" Interior Plastic Care","description":"\u003ch2 id=\"speakable-headline\"\u003eSatin-matt shine in the interior with the Koch-Chemie Top Star \"Ts\"\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Top Star \"Ts\"?

It works through polyfunctional reactive components that bond with the paint surface in a network-like structure.

After 3–4 applications the difference to a one-off sealant is there to see — in the gloss level and in how the water sheets off.

Day-to-day you save 5–10 minutes of drying per wash, because all you do is wipe the leftover water off edges and mirrors. Koch-Chemie calls this \"Micro-Bead-free Drying\" — the water forms no standing droplets, it runs off in sheets.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProtection beyond the paint.\u003c\/strong\u003e The Pw preserves more than just paint — it also seals rubber and plastic trim as well as convertible tops. UV light and road salt are cut back by the wax layer, so plastics fade less and rubber seals stay supple. VDA-compliant Class A, which means it's also cleared for biological wash-water treatment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e Always lay the Protector Wax down on the wet, freshly washed car — never on dry paint. Spray the concentrate on neat and you risk streaks on dark paint, because the active concentration is too high. The right dilution: 30 ml per 1 litre of water. Best applied with a foam sprayer, which gives you even coverage and less product waste. Rinse it off thoroughly with the pressure washer within 3–5 minutes — never let it dry on.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e30 ml per 1 litre of water. Spray on. Rinse off.\u003c\/h3\u003e\n\u003cp\u003eApplying the Koch-Chemie Protector Wax takes under 10 minutes and works with no polisher, no microfibre cloth and no cure time. That sets it apart from hard waxes, which need 20–30 minutes of working time per car, or ceramic coatings, which take paint correction as prep.\u003c\/p\u003e\n\n\u003cp\u003eMix 30 ml of concentrate into 1 litre of water — best in a foam sprayer like the Gloria FM10 or a pump-up spray bottle. Spray the solution evenly onto the wet, freshly washed car. Start at the roof and work your way down: bonnet, wings, doors, bumpers.\u003c\/p\u003e\n\n\u003cp\u003eThe product works straight away — you can see from the changed surface tension that the reactive components are keying in. The 1:33 dilution sounds light, but it's chosen on purpose: Koch-Chemie designed the Pw for car-wash use, where only 13–19 ml goes on undiluted per car.\u003c\/p\u003e\n\n\u003cp\u003eAfter 2–3 minutes of dwell time, rinse everything off with the pressure washer, top to bottom. Thoroughly, with plenty of water. This is the critical step: rinse too little and you get white wax residue on dark paint.\u003c\/p\u003e\n\n\u003cp\u003eThen wipe the leftover water off mirrors, door edges and the fuel cap with a drying towel. The rest runs off on its own thanks to the sheeting. A common mistake we see day-to-day: some people then spray a finish spray on top. That's counterproductive, because the spray partly lifts the fresh wax layer back off.\u003c\/p\u003e\n\n\u003cp\u003eKoch-Chemie offers its own spray bottle with a printed dilution scale — handy, but not a must. Any standard pump sprayer or foam sprayer does the job. At a self-service wash bay you apply the solution right after the rinse cycle and use the bay's pressure washer to rinse off.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-protector-wax-pw-konservierungswachs-nassversiegelung-anwendung.jpg?v=1776077464\" alt=\"Koch-Chemie Protector Wax Pw being sprayed on as a wet sealant\" loading=\"lazy\" width=\"1493\" height=\"2000\"\u003e\n\n\u003ch3\u003eThe Pw builds gloss and protection. It doesn't fill scratches.\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie Protector Wax gives you a deep, wet high gloss — especially visible on dark paint after the third or fourth application. The gloss build is cumulative: every layer cross-links with the one before.\u003c\/p\u003e\n\n\u003cp\u003eDay-to-day, a single application lasts 3–5 weeks. That sounds short next to ceramic coatings with 12+ months of durability — but it's a different concept. The Pw is a care routine, not a one-off shield.\u003c\/p\u003e\n\n\u003cp\u003eIf you wash every 1–2 weeks and apply the Pw each time, you've got lasting protection that beats a neglected one-off sealant. Detailers in the community report that after a week of bad weather and 1,000 kilometres their car was cleaner than after a hand wash without the Pw.\u003c\/p\u003e\n\n\u003cp\u003eThat comes down to the Lotus effect: dirt particles cling less to the hydrophobic surface and get partly washed off by the next rain. This self-cleaning behaviour is called sheeting — the water forms no standing droplets (beading), it runs off as a closed film and carries dirt particles with it. The Pw gives you both: beading across the flat panels and sheeting at the edges.\u003c\/p\u003e\n\n\u003cp\u003eWhat the Protector Wax can't do: fill scratches or restore oxidised paint. Fine swirls are visually masked by the gloss build, but not chemically bonded. If you've got visible scratches, you need a polish first before the wax makes sense. The order: wash, polish, then seal with the Pw — not the other way round.\u003c\/p\u003e\n\n\u003cp\u003eOn ceramic-coated cars the Pw is redundant — the coating already has better durability and hydrophobicity. Here the \u003ca href=\"\/en\/products\/koch-chemie-spray-sealant-s0-02-spruehversiegelung\"\u003eKoch-Chemie Spray Sealant S0.02\u003c\/a\u003e is the better pick as a coating top-up.

No prep, no cure time, no re-buffing. Spray on, rinse off, done. If you want your paint protected between washes without booking in a dedicated sealing day, the Pw is the right tool.\u003c\/p\u003e\n\n\u003cp\u003eThe Pw makes particular sense if you wash weekly or every other week and don't want to plan in a separate sealing step. For self-service-bay users it slots straight into the existing wash routine. With a pleasant cherry scent instead of the typical chemical smell of many wax products, you can use it in an underground car park or with the garage door shut, too. It works on glass as well — the windscreen picks up a light water-repellent effect from the Pw that improves visibility in the rain.\u003c\/p\u003e\n\n\u003cp\u003eThe Protector Wax is less suited to you if you only wash every 4–8 weeks. The protection layer won't build then and you're better off with the \u003ca href=\"\/en\/products\/koch-chemie-hydro-foam-sealant-s0-03-nassversiegelung-konzentrat\"\u003eKoch-Chemie Hydro Foam Sealant S0.03\u003c\/a\u003e. As a foam sealant in the pressure-washer workflow, the Hydro Foam Sealant gives longer durability per single application. For an overview of all the options, take a look at our \u003ca href=\"\/en\/collections\/spruehversiegelung\"\u003espray sealant\u003c\/a\u003e category.\u003c\/p\u003e\n\n\u003cp\u003eWith the 1-litre bottle and 30 ml per wash you get around 33 applications — that's half a year at weekly use. The 10-litre version pays off for businesses and fleets running several cars. The 20-litre version is meant for car-wash operators and commercial detailers who dose the Pw by machine.\u003c\/p\u003e\n\n\u003cp\u003eStore frost-free, and never keep diluted product — always mix it fresh. The reactive components lose their cross-linking ability once diluted. The concentrate itself keeps indefinitely when stored correctly between 5 and 30 °C. A tip for winter: the Pw contains no mineral oil hydrocarbons, which makes it kinder to the environment than many solvent-based wax products — relevant if you wash at a self-service bay with biological waste-water treatment.\u003c\/p\u003e\n\n\u003cp\u003eThe full wash workflow with the Protector Wax looks like this: pre-wash with snow foam, contact wash with car shampoo using the two-bucket method, rinse clear, spray the Pw on and rinse off. Under 30 minutes for the whole car, sealing included. No separate step, no swapping tools, no extra drying time thanks to the sheeting effect. That makes the Protector Wax the logical finish to any hand wash — from the occasional washer to the fleet operator.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-protector-wax-pw-konservierungswachs-nassversiegelung-lineup.jpg?v=1776077468\" alt=\"Koch-Chemie Protector Wax Pw 1 litre bottle and 10 litre canister\" loading=\"lazy\" width=\"2000\" height=\"1493\"\u003e","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48489158148431,"sku":"D1-KCX-319001","price":29.49,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml","offer_id":49764590747983,"sku":"D1-KCX-319001_2","price":62.7,"currency_code":"EUR","in_stock":true},{"title":"3x 1000 ml","offer_id":49764591010127,"sku":"D1-KCX-319001_3","price":93.09,"currency_code":"EUR","in_stock":true},{"title":"10 liters","offer_id":48762521289039,"sku":"D1-KCX-319010","price":147.49,"currency_code":"EUR","in_stock":true},{"title":"20 liters","offer_id":49673116418383,"sku":"D1-KCX-319020","price":279.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-protector-wax-pw-konservierungswachs-nassversiegelung.png?v=1721902170"},{"product_id":"koch-chemie-cockpit-super-pflege-csp-kunststoffpflege-glaenzend","title":"Cockpit-Super-Pflege \"Csp\" Interior Plastic Dressing (Glossy)","description":"\u003ch2\u003e\u003cstrong\u003eKoch-Chemie Cockpit-Super-Pflege \"Csp\" – Interior Plastic Dressing (Glossy)\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eMeet the \u003cstrong\u003eKoch-Chemie Cockpit-Super-Pflege \"Csp\"\u003c\/strong\u003e – the dressing your cabin plastics have been waiting for.

We often get messages like \"the glass cleaner leaves streaks\". Usually the wiping happened on a warm pane in the sun, where the film flashes off before the cloth lifts it. Work on a cold pane in the shade and go by the two-cloth rule: lift the dirt with 1 damp cloth, then buff dry in straight passes with a dry glass cloth. More product doesn't clean better, it tends to leave edges.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on neat, pull it off streak-free with two cloths\u003c\/h3\u003e\n\u003cp\u003eYou spray the Glass Cleaner \"Gc\" on neat from 20 to 30 cm onto the cold, shaded pane and pull it off with a dry microfibre glass cloth in straight passes. That way no film of water is left standing to flash off.\u003c\/p\u003e\n\u003cp\u003eOutside, the cleaner lifts bug splatter, pollen and the greasy road film. With a baked-on bug front, let the cleaner soak for about 30 seconds and only then pull it off, rather than scrubbing harder. That goes easy on the glass and on the wiper blades.\u003c\/p\u003e\n\u003cp\u003eInside, it's about the greasy film off-gassing from the dash and about nicotine. If you want to \u003cem\u003eclean your car windows from the inside\u003c\/em\u003e, spray sparingly onto the cloth rather than straight onto the glass, so no mist drifts onto a display or a vent. With a \u003ca href=\"\/en\/products\/the-rag-company-diamond-280-gsm-mikrofaser-glastuch\"\u003emicrofibre glass cloth\u003c\/a\u003e especially, the cloth quality decides whether the loosened dirt gets picked up or just smeared around.\u003c\/p\u003e\n\u003cp\u003eThe second, bone-dry pass over the finished pane lifts the last haze out. That's exactly the step most people skip, and that's exactly where you get the streaks you spot later in backlight. A good glide additive makes the difference here between any old cleaner and a real car glass cleaner.\u003c\/p\u003e\n\u003cp\u003eWhy the cold pane? The additive only works its glide as long as the film is liquid. On hot glass the water flashes off too fast, the cleaner grabs and the cloth just pushes the dirt around. In the shade or early in the morning you've got that window of time. Wash new microfibre cloths once without softener before they ever touch glass too, otherwise they carry sizing onto it that pulls streaks all by itself.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-glass-cleaner-gc-glasreiniger_anwendung.png?v=1780006597\" alt=\"Koch-Chemie Glass Cleaner Gc being sprayed on a car window and pulled off with a microfibre cloth\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWhat the Gc is built for and what it isn't\u003c\/h3\u003e\n\u003cp\u003eThe Gc cleans glass, it doesn't seal it and it doesn't belong in the washer reservoir. As a pure spray-and-wipe cleaner it replaces neither the antifreeze washer fluid in the reservoir nor a hydrophobic glass sealant for the beading effect.\u003c\/p\u003e\n\u003cp\u003eWith heavily baked-on residue, 1 pass isn't always enough. One verified customer puts it well: with stubborn dirt you need 2 to 3 passes rather than scrubbing under pressure. A short soak and another pull is gentler and quicker in the end, because you avoid scratches you'd have to polish out later.\u003c\/p\u003e\n\u003cp\u003eAnti-fog protection is something the Gc deliberately leaves out. It gets you clean, clear glass, but against fogging from the inside only an anti-fog treatment helps for the long run. Clean glass does fog up far more evenly though, and so far less of a bother than a greasy film.\u003c\/p\u003e\n\u003cp\u003eBeyond the car the Gc cleans mirrors, interior and exterior, motorcycle visors, instrument glass and smooth surfaces around the house like tiles or stainless steel. The only place to be careful is on matte anti-glare nav and instrument displays: there you always spray onto the cloth and work with little pressure, so the coating doesn't suffer. On clear glass and glossy plastic headlights it works with no restrictions.\u003c\/p\u003e\n\u003cp\u003eIn a smoker's car a tacky nicotine film settles on the inside glass, scattering the light and making everything look yellowed. Here you work in 2 layers: lift and roughly take it off first, then buff dry with a fresh cloth. After that first thorough clean a normal pass later is enough to keep the view clear.\u003c\/p\u003e\n\u003cp\u003eIf you want to work ready-to-use and stay film- and tint-safe, the Gc is the right call.

The commuter grabs the 1-litre bottle, the detailer the 10 or 20-litre container.\u003c\/p\u003e\n\u003cp\u003eGlass cleaners are in highest demand in spring: pollen and bug season drives demand about 40 percent over the quiet winter level. If you've got a bottle in the boot now, you clean the windscreen on the road instead of driving into the low sun with a pollen film and streaks.\u003c\/p\u003e\n\u003cp\u003eDay-to-day the difference shows in the details: no streaks in backlight, no haze on the inside glass that turns oncoming headlights into stars at night. If you drive a lot with the sun low or in the dark, you notice a streak-free pane straight away.\u003c\/p\u003e\n\u003cp\u003eThe Gc is fuss-free on cost: 1 litre ready-to-use lasts many weeks of commuter life depending on how much you spray, and decanting the 10-litre container into a spray bottle costs you far less per litre. Store the cleaner frost-free and the spray function stays reliable across the whole shelf life. An opened bottle in the car survives the summer heat better if it isn't left baking in full sun all the time.\u003c\/p\u003e\n\u003cp\u003eHow often you clean depends on your driving: if you commute daily, keep the windscreen clear inside about every 2 weeks and outside as needed with pollen or bugs. High-mileage drivers and detailers with several cars a day get the most out of the big container and a spray bottle fixed to the trolley. That turns reaching for the car glass cleaner into routine rather than the exception.\u003c\/p\u003e\n\u003cp\u003eThe one trick hardly anyone does and that stops most streaks: clean the inside first, then the outside, and pull horizontally inside, vertically outside. If a streak is left after cleaning, the direction tells you straight away whether it's on the inside or the outside, and you only fix it there. That saves you the third pass and the guessing.

If you care for your exterior plastic with PSS and also plan to mask off, foil or wax, treat PSS as the \u003cem\u003elast\u003c\/em\u003e step in the workflow. Order in practice: polish the paint, set the masking tape, then APC 1:10 as a pre-clean on the plastic, let it dry, only then put PSS on an applicator sponge, not on microfibre, which sucks too much product out of the bottle.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eApply Plast Star after polishing, not before\u003c\/h3\u003e\n\n\u003cp\u003eThe right order decides the result. \u003cstrong\u003ePlast Star \"Pss\"\u003c\/strong\u003e belongs after every paint job, not before. A barrier film sitting on the plastic before you polish clogs your pads and turns the paint job uneven.\u003c\/p\u003e\n\n\u003cp\u003eBefore PSS goes on the plastic, you pre-clean. The \u003ca href=\"\/en\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star \"Gs\" all-purpose cleaner\u003c\/a\u003e 1:10 in water, spray on, let it work briefly, rinse off. This APC pre-clean opens the pores of an oxidised bumper and lets the micro-emulsion penetrate instead of just sitting on the surface. The manufacturer doesn't prescribe this step; in practice it adds two to three months of durability.\u003c\/p\u003e\n\n\u003cp\u003eOnce the plastic is fully dry, the product goes on with an applicator sponge. Microfibre is the wrong tool here because it pulls too much product out of the bottle. For an average bumper, two firm pumps from the bottle are enough, spread evenly across the surface, work it thoroughly into the material. On tyre sidewalls a bit more, about three pumps per tyre.\u003c\/p\u003e\n\n\u003cp\u003eAfter working it in, don't wipe again. That measurably shortens durability. PSS dries in 5 to 15 minutes depending on ambient temperature, and exactly in that phase the micro-emulsion bonds with the substrate. During drying: no water contact, no cloth, no wax on top.\u003c\/p\u003e\n\n\u003cp\u003eIf you work on a warm bumper in the sun, drying is on the shorter side. In cool weather below 12 C plan for 15 minutes, on really cold days below 5 C better skip the job because polymer crosslinking won't run cleanly. The \u003cstrong\u003ecar exterior plastic care\u003c\/strong\u003e is done after this drying time. No polishing, no buffing, no second coat.\u003c\/p\u003e\n\n\u003cp\u003eA second coat brings nothing. Worse, it partly re-dissolves the layer that has already crosslinked.

On the plastic itself PSS is not top-coatable: a wax on top builds a greasy, uneven layer that streaks after the first rain.\u003c\/p\u003e\n\n\u003cp\u003eAlso not for grip-relevant surfaces: pedals, steering wheel, gear lever and tyre tread. The manufacturer flags this because PSS creates a slippery surface there. Interior cockpits are not the Pss application area either. For those, \u003ca href=\"\/en\/products\/koch-chemie-top-star-ts-innenraum-kunststoffpflege\"\u003eTop Star \"Ts\"\u003c\/a\u003e is the right call, with its own formula for dashboards and door cards inside.\u003c\/p\u003e\n\n\u003cp\u003eIf you want the same effect in concentrate form, at a 1:5 to 1:10 dilution for economical use in workshops, reach for Hydro Plast Care \"Hpc\".

A solvent-based specialist cleaner built on C10–C13 hydrocarbons that chemically breaks down tar, bitumen, oil and grease residue — neat on a dry surface, 30 seconds to 3 minutes dwell time, then rinse off with a pressure washer. Carries Daimler approval and is free of halogenated hydrocarbons.

The active blend — C10–C13 n-alkanes, isoalkanes and cycloalkanes with under 2 percent aromatics — chemically breaks apart the molecule chains in bitumen and tar. The residue runs off in streaks and you either steam it away with the pressure washer or wipe it off with a microfibre cloth.\u003c\/p\u003e\n\n\u003cp\u003eFree of halogenated hydrocarbons, so it's a lot kinder to materials than the old-school tar removers people kept in jerry cans back in the 90s. Available in 1 litre, 10 litre and 20 litre — plus a 2-pack and 3-pack when you need more. Alongside the alkane blend the formula carries a share of 2-butoxyethanol as a coupling agent, which improves how it wets a glass-smooth panel and keeps it working even at cooler ambient temperatures. For indoor use, run ventilation above three air changes an hour, and eye protection is a must for any overhead work.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical, not mechanical.\u003c\/strong\u003e You can't polish tar out — scrubbing drags the particles across the paint and leaves swirls behind.

The brush stays in the drawer.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDaimler approval as a green light for pro use.\u003c\/strong\u003e Koch-Chemie works hand in hand with the car industry.

Teerwäsche A works with a modern hydrocarbon blend that's workable in well-ventilated spaces from about 15 °C.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e Teerwäsche A doesn't just break down tar — it strips the wax or sealant underneath along with it. That's the bit manufacturers and rivals rarely mention. If you do nothing after the tar comes off, you're left with unprotected paint that takes on fallout and water spots with no barrier. So always plan it in as the first step of a combo job: tar wash → normal wash with a pH-neutral shampoo → reseal with a \u003ca href=\"\/en\/products\/sonax-profiline-speedprotect-spruhversiegelung\"\u003espray sealant\u003c\/a\u003e or wax. For a spot job (the odd tar fleck on the sill) a quick detailer is enough as local protection. For a full exterior job including resealing, set aside about 45 minutes for a mid-size car.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on neat. Short dwell. Steam it off.\u003c\/h3\u003e\n\n\u003cp\u003eThe application is kept deliberately simple. Lay Teerwäsche A on the dry, cold surface undiluted — either straight from the 1-litre bottle with the \u003ca href=\"\/en\/products\/koch-chemie-teerwaesche-a-tea-bitumen-teerentferner?variant=54013040492879\"\u003eCanyon spray head CHS-3AN\u003c\/a\u003e or from a sturdy solvent-safe spray bottle. A wet surface dilutes the solvent and cuts the cleaning power right down — when washing, tar wash first, then shampoo.\u003c\/p\u003e\n\n\u003cp\u003eDwell time runs from 30 seconds to 3 minutes — depending on how thick the tar layer is. You can see when it's working: the tar dissolves into brownish-black streaks and runs down vertical surfaces. As soon as that happens, rinse straight off with a strong jet of water or wipe it away with a clean microfibre cloth. A 1000 ml bottle covers roughly 4 to 6 full vehicle sides with moderate tar.\u003c\/p\u003e\n\n\u003cp\u003eOn bigger areas, don't let it dry — in direct sun or on hot paint above 25 °C the solvent flashes off too fast and leaves an oily film that only comes off at the next wash. For underbody or wheel-arch work on commercial vehicles, the 10 or 20 litre version is the right call.\u003c\/p\u003e\n\n\u003cp\u003eThere you apply it over a wide area with a pump sprayer and then steam it off with the pressure washer at around 120 bar. On stubborn, dried-on bitumen spots after a drive through roadworks, a second application does more than a longer dwell on the first pass — the solvent is saturated after about 3 minutes and stops working.\u003c\/p\u003e\n\n\u003ch3\u003eIt breaks down tar. And wax too.\u003c\/h3\u003e\n\n\u003cp\u003eTeerwäsche A attacks any organic coating sitting on the paint. That's how it works — and at the same time it's the one catch for anyone who reaches for it without a plan. Carnauba waxes, synthetic polymer-based sealants and most quick detailers dissolve away on contact with the hydrocarbon blend. That's no fault in the product either, it's chemistry: what breaks down bitumen breaks down wax too, because both are built on similar organic molecule structures.\u003c\/p\u003e\n\n\u003cp\u003eFor the real world that means two things. First: every tar wash is followed by a full paint wash with a pH-neutral shampoo to neutralise the solvent residue. Second: the treated spot needs a fresh layer of protection.\u003c\/p\u003e\n\n\u003cp\u003eIf you're only dealing with small flecks on the side sill, you can follow up with a spot wax or detailer. If you're cleaning whole panels or the underbody, build the reseal into the workflow as a fixed step. SiO₂-based ceramic coatings usually aren't fully wrecked after a tar-wash treatment, but they lose noticeable hydrophobicity — a topper or detailer brings them back up to level.\u003c\/p\u003e\n\n\u003cp\u003eWhat Teerwäsche A isn't suited to: unpainted soft plastics, rubber seals and EPDM profiles. The solvent swells rubber over longer contact and can dull plastics. It mainly hits window seals, door rubbers and black plastic trim on older vehicles.\u003c\/p\u003e\n\n\u003cp\u003eDon't spray it over those surfaces broadly — if overspray happens, rinse it off with water within 60 seconds. On fresh wraps and PPF (paint protection film), test first on a hidden spot. Plenty of PPF coatings handle short contact times under 30 seconds but react sensitively to longer exposure.\u003c\/p\u003e\n\n\u003ch3\u003eWhen Teerwäsche A fits — and when it doesn't\u003c\/h3\u003e\n\n\u003cp\u003eTeerwäsche A is the right call when you're removing genuine road tar, bitumen spray after driving through roadworks, asphalt residue on wheel arches or dried-on oil films in the underbody area. It's also built for the regular cleaning of car-wash brushes and shop floors — wherever it's not paint cosmetics that's needed but real chemical solving power. In the spring season after winter it's standard for underbody prep, once tar-salt mixes have piled up over months.\u003c\/p\u003e\n\n\u003cp\u003eFor insect residue, though, it's not the first choice. Insect proteins are organic but structured differently — enzymatic cleaners like the \u003ca href=\"\/en\/collections\/insektenentferner\"\u003einsect remover\u003c\/a\u003e work more precisely and more gently on paint there. If you've got both at once — tar on the sill, bugs on the front end — treat both areas separately with the product that fits each. Trying to solve everything with one all-rounder usually ends in more rework. Same goes for tree sap and adhesive residue: both dissolve with the tar wash, but a dedicated tree-sap remover works cleaner.\u003c\/p\u003e\n\n\u003cp\u003eAs for pack size, the 1-litre bottle suits the private user and the occasional detailer planning one go per vehicle. The 2-pack and 3-pack bring the price per litre down by roughly 5 to 15 percent — worth it if there are several vehicles in the household or you want the season's supply locked in.\u003c\/p\u003e\n\n\u003cp\u003eThe 10 and 20 litre drums are trade sizes for reconditioning, underbody cleaning or fleet work — here the outlay only pays off from regular weekly use. For precise single-spot application the 1-litre bottle with the Canyon spray head stays the most ergonomic solution. The spray head delivers a precise cone rather than a mist and doses right onto the problem spot without wetting more area than needed.\u003c\/p\u003e\n\n\u003cp\u003eStore Teerwäsche A frost-free at room temperature. Once opened, the bottle stays stable for about 24 months as long as the cap is closed tight after use — hydrocarbon solvents evaporate slowly otherwise and the concentration drops.\u003c\/p\u003e\n\n\n\u003chr\u003e\n\n\u003cdiv class=\"care-guide\"\u003e\n  \u003ch3\u003eHow to use Koch-Chemie Teerwäsche A\u003c\/h3\u003e\n\n  \u003col\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrep.\u003c\/strong\u003e Move the vehicle into the shade, paint temperature under 25 °C.

A fresh bitumen fleck dissolves in under a minute, dried-on road tar after a drive through roadworks takes up to 3 minutes. After 3 minutes the active is saturated — longer dwell brings no extra cleaning power. On stubborn residue, better to apply a second time.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes Teerwäsche A also remove insect residue?\u003c\/summary\u003e\n    \u003cp\u003ePartly. Insect proteins only partly dissolve in hydrocarbon solvents. For insect residue, an enzymatic insect remover like the Meguiar's Bug Remover or CarPro Bug-Out is a lot more effective and gentler on paint. Teerwäsche A is the go-to for bituminous soiling, oil and grease film and adhesive residue — on protein soiling it won't get you into the top league.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eIs Teerwäsche A suitable for rubber and plastic?\u003c\/summary\u003e\n    \u003cp\u003eNo. Hydrocarbon-based solvents swell rubber seals and can dull soft plastics like ABS or PP. This hits window seals, door rubbers, EPDM profiles and black plastic trim on older vehicles. If overspray happens, rinse off with clean water within 60 seconds. On paint protection films (PPF) and fresh wraps, test first on a hidden spot.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eDo I have to reseal after the tar wash?\u003c\/summary\u003e\n    \u003cp\u003eIf you're treating more than the odd fleck: yes. Teerwäsche A strips waxes and sealants on the treated area along with the tar. For single spots a quick detailer or spot wax is enough. On whole panels or underbody cleaning, a spray sealant or a wax belongs firmly in the workflow. Ceramic coatings usually survive the job but lose hydrophobicity — an SiO₂ topper brings them back up to level.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eWhich pack size is right for me?\u003c\/summary\u003e\n    \u003cp\u003eFor private users with one vehicle, the 1-litre bottle is enough — it covers roughly 4 to 6 full vehicle sides. If you look after several cars or stock up for the season, go for the 2-pack or 3-pack with 5 to 15 percent off per litre. The 10 and 20 litre drums are trade sizes for vehicle reconditioning, underbody cleaning and fleet work.
