A highly concentrated snow foam with a cranberry note for the touchless pre-wash. Mildly alkaline (pH 9), so a touch more active than a neutral foam, but more effective against road film and bugs. Not the right foam if you're keeping a natural wax as your sealant.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eKoch-Chemie Active Foam Berry Boost\u003c\/strong\u003e is a \u003cstrong\u003esnow foam\u003c\/strong\u003e concentrate from Unna, built for commercial gantry washes, self-serve bays and ambitious detailers running a foam lance. Free of phosphates and nitrilotriacetate, so without the problematic chelating agents of older foams. The cranberry note — that's how Koch-Chemie markets the berry-scent version — comes from geraniol and sweet-orange extract, a sensory reconstruction of the cranberry identity without any real cranberry extract. The in-use pH sits at 9. In practice: active enough to cut grease, without going at modern clear coats.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMildly alkaline with bite.\u003c\/strong\u003e pH 9 dissolves greasy road grime and bug splatter, but leaves modern clear coats untouched. That's the gap between a pH-neutral snow foam (gentle, but barely cleans) and a strongly alkaline pre-cleaner (cuts through everything, but eats into bare aluminium wheels). What that means for you: a foam that genuinely replaces the pre-wash, with no need to polish afterwards.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVDA Class A, tested on OEM materials.\u003c\/strong\u003e The German carmakers have cleared the formula on paint, plastics, chrome and rubber seals — provided you stay at a maximum of one percent concentration on the paint and a five-minute dwell time. That's the legal basis a detailer needs to wash premium cars with wraps or paint protection film with no liability risk.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e21 kg drum, cranberry note, 5 ml per car.\u003c\/strong\u003e Pro consumption in self-serve setups runs 3 to 8 ml per car. With the 21 kg drum you get anywhere from 2,500 to 6,500 washes, depending on the setup. That's the scale of a detailing business doing five to ten cars a day that won't reorder for two years.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e We see the same mistake in every other enquiry. A customer fills their 1-litre pump sprayer with Active Foam for the first time, 20 millilitres of concentrate to 1 litre of water, tightest filter nozzle, lever down. Out comes a thick carpet of shaving foam. Looks spectacular on Instagram, but it doesn't clean. Dense foam clings to the paint instead of running off with the dirt. The Detailing1 rule: 5 ml to 1 litre, medium filter nozzle, and you're after a wet foam that flows off slowly and drags the dirt all the way down to the sill.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eDialling in Berry Boost in the foam-cannon workflow\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eBerry Boost\u003c\/strong\u003e needs a setup that matches its concentration: a pressure washer from 110 bar up plus a foam cannon with a stainless filter screen, not a garden pump sprayer maxing out at 0.5 bar.\u003c\/p\u003e\n\n\u003cp\u003eIn the foam-cannon bottle you mix 1:5 to 1:30, depending on how dirty the car is and the water hardness in your region. Hard water (above 14 degrees German hardness) binds surfactants and neutralises part of their cleaning power. You'll want the upper concentration then. With soft water, 1:30 is plenty for a weekly maintenance wash. Go heavy at the start, sparing at the end, and never work from the paint toward the door — foam from the bottom up so run-off marks don't dry on prematurely.\u003c\/p\u003e\n\n\u003cp\u003eBehind the cleaning logic sits simple surfactant chemistry. The concentrate holds 15 to under 30 percent anionic surfactants, water-loving and fat-loving molecules that act like little magnets: one end latches onto dirt particles, the other stays in the water. Since clear coat is also slightly negatively charged, the negative head group pushes the encapsulated dirt away from the surface. What that means for you: the dirt gets wrapped up and carried off with the run-off foam, not rubbed into the paint the way mechanical friction does it.\u003c\/p\u003e\n\n\u003cp\u003eMaximum dwell time on the paint is 5 minutes — binding under the VDA material approval. Let the surfactant mix dry on and the alkaline residue burns into the clear coat, so-called alkaline stains, which only come off with a machine polish. In summer, park the car in the shade first, cool it down quickly with clear water at the open self-serve bay, and only then foam it.\u003c\/p\u003e\n\n\u003cp\u003eIn cold weather the concentrate turns viscous. Before the first fill of a foam cannon in winter, take the bottle indoors for a bit, otherwise the feed pressure stalls and you get inconsistent mix ratios. A \u003ca href=\"\/en\/collections\/zubehoer-detailing\"\u003efoam cannon\u003c\/a\u003e running a steady 110 bar solves the problem mechanically.\u003c\/p\u003e\n\n\u003cp\u003eConsumption in the foam-cannon workflow runs 50 to 100 ml of diluted mix per car, so roughly 5 to 10 ml of concentrate per car. On that basis the 21 kg drum washes between 2,000 and 4,000 cars. For a self-serve bay with a dosing pump it's 3 to 8 ml neat per car, which doubles the yield. Both figures apply to moderate dirt. With pollen in spring or after salty weather in winter, lean toward the upper limit, otherwise the dirt sticks in the foam instead of running off with it.\u003c\/p\u003e\n\n\u003ch3\u003eMildly alkaline strips carnauba. If you love wax, read on here\u003c\/h3\u003e\n\n\u003cp\u003eThe honest limitation of the \u003cstrong\u003eBerry Boost\u003c\/strong\u003e is also its biggest strength: the mildly alkaline character. It reliably dissolves grease from bug splatter, road film and old quick-detailer residue, but it also loosens that last coat of natural wax.\u003c\/p\u003e\n\n\u003cp\u003eCarnauba waxes and light polymer sealants react over time to alkaline surfactants. Carnauba is chemically a plant wax that gets broken down bit by bit through repeated saponification. Picture wiping a candle down with washing-up liquid again and again — eventually it's gone. After several weekly washes the beading goes flatter, the water creeps instead of rolling. If you lovingly look after your car at the weekend with a hand wax or a spray-wax top-up, you shouldn't reach for Active Foam for the weekly maintenance. For that niche the pH-neutral \u003ca href=\"\/en\/products\/koch-chemie-gentle-snow-foam-gsf-reinigungsschaum\"\u003eGentle Snow Foam \"Gsf\"\u003c\/a\u003e is the better call, same maker, different job.\u003c\/p\u003e\n\n\u003cp\u003eWith modern ceramic coatings the story is different. A ceramic layer is a cross-linked glass lattice, permanently bonded to the paint, far more stable than a wax film. Mildly alkaline foams can't touch it.\u003c\/p\u003e\n\n\u003cp\u003eMore than that: the alkaline foam pulls oily traffic-film residue out of the micro-pores of the ceramic. If your 18-month-old coating suddenly no longer rolls but crawls, that's often not material damage but a clogged surface. A concentrated Active Foam wash burns that contamination clear and the beading comes back. That's the off-label use the pros know about, but you won't find it on any manufacturer's brochure.\u003c\/p\u003e\n\n\u003cp\u003eThe second concrete limit: the foam must not dry on. At outside temperatures above 25 degrees or in direct sunlight, the water in the foam evaporates within seconds. The surfactant concentration shoots up locally and burns into the clear coat as an etch mark. If you wash in summer: car into the shade, cool it down with clear water, only then lay the foam on. If you're working without shade: keep strictly to the 5-minute maximum dwell time and rinse off immediately before the next section.\u003c\/p\u003e\n\n\u003cp\u003eWhat the Berry Boost \u003cem\u003ecan't\u003c\/em\u003e do: shift baked-on brake dust on wheels. For that you need the acid-based workflow with the \u003ca href=\"\/en\/products\/koch-chemie-magic-wheel-cleaner-mwc-felgenreiniger\"\u003eMagic Wheel Cleaner \"Mwc\"\u003c\/a\u003e. The foam keeps wheels clean when they're already clean — it's care, not a reset.\u003c\/p\u003e\n\n\u003ch3\u003eFor commercial detailers, not for the Sunday wash\u003c\/h3\u003e\n\n\u003cp\u003eThe 21 kg drum with SKU D1-KCX-695-20L-01 is aimed at the pros: gantry-wash operators, detailing businesses, commercial detailers foaming several cars a day. In the DACH market the search for touchless pre-wash is climbing right now — over the last eight weeks snow foam has averaged about nine percent more search volume than its twelve-month average. The market is pulling noticeably toward the foam cannon.\u003c\/p\u003e\n\n\u003cp\u003eAt 5 ml per car in a hand wash, the drum lasts for around 4,000 cars. That's the scale of a detailing business doing five to ten cars a day that won't reorder for two years. For a hobbyist with one wash a week, this container size is simply overkill. If you want the berry scent at home, wait for the 1- or 5-litre fills, or stick with the \u003ca href=\"\/en\/products\/koch-chemie-active-foam-af-intensivschaum\"\u003eActive Foam \"Af\"\u003c\/a\u003e with sandalwood scent, which comes in smaller sizes in the range.\u003c\/p\u003e\n\n\u003cp\u003eIn a B2B context the VDA Class A approval is the real reason to buy. The German carmakers have tested and cleared the formula on original materials. That's more than just a marketing seal, it's the material guarantee in black and white.\u003c\/p\u003e\n\n\u003cp\u003eIf you stick to the maximum concentration of one percent on the paint and a 5-minute dwell time, the foam demonstrably doesn't attack paint, plastics, chrome parts or rubber seals. For a detailer washing premium cars with wraps or paint protection film, that's the legal footing against damage claims. A US import without this approval may be chemically similar, but in court, in the event of damage, it's worthless.\u003c\/p\u003e\n\n\u003cp\u003eThe off-label use we see most often in enquiries is the wheel-bucket hack: a shot of Berry Boost in the separate wheel bucket of the two-bucket method. On regularly maintained wheels with no baked-on brake dust, the mildly alkaline foam fully replaces reaching for the aggressive acidic wheel cleaner. The wheel comes up clean and the wheel's clear coat stays untouched.\u003c\/p\u003e\n\n\u003cp\u003eThat workflow is exactly what the OEM approval had in mind: not just for the main wash, but for every spot on the car where a cleaner touches the paint. The trick no manufacturer prints in its brochure, because it undercuts the sale of a separate wheel cleaner: a concentrate that keeps clean wheels clean saves you the aggressive acidic product for the genuine hard cases.\u003c\/p\u003e\n\n","brand":"Koch-Chemie","offers":[{"title":"20 liters","offer_id":57637057495375,"sku":"D1-KCX-695-20L-01","price":110.82,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-active-foam-berry-boost-afb-intensivschaum-cranberry-duft_20-liter.png?v=1778704441","url":"https:\/\/detailing1.be\/en\/products\/koch-chemie-active-foam-berry-boost-afb-intensivschaum-cranberry-duft","provider":"Detailing1","version":"1.0","type":"link"}
