SONAX PROFILINE Stain Ex Adhesive Remover 1000ml

Residue-Free Removal of Adhesives, Labels, and Adhesive Residues — SONAX PROFILINE Stain Ex

What does SONAX's professional adhesive remover do? The solvent-based spray removes adhesive residues, labels, stickers, tar, wax, and stubborn stains residue-free from paint, glass, metal, and plastic surfaces — without mechanical scrubbing and without damaging surfaces.

In professional detailing and vehicle reconditioning, detailers regularly encounter a wide spectrum of stubborn stains and residues that cannot be removed with normal cleaners: adhesive from removed film lettering, price and type plate labels, tar residues from the underbody, wax deposits, and stubborn tar spatters from road abrasion. The SONAX PROFILINE Stain Ex is the universal adhesive remover for all these applications: solvent-based, but optimized for paint-friendly use, and available in 1-liter containers for regular professional use.

• Removes adhesive, labels, and stickers without leaving residues. Adhesive residues from removed films, stickers, and factory labels are made of plastic polymers that can be dissolved and detached from the surface with solvent-based chemistry. Stain Ex dissolves these polymer chains and makes them wipeable — without mechanical abrasion and without leaving residues on the paint. Especially for vehicles after film lettering or lettering film removal, the adhesive remover is indispensable for a residue-free result.
• Effective against tar, wax, and stubborn stains. Tar residues from road asphalt and bitumen adhere stubbornly to paint and plastics due to their thermoplastic properties — normal washing does not remove them. Stain Ex chemically dissolves the tar and makes it wipeable, without creating scratches through mechanical abrasion. Wax residues on paint, wax on rubber seals, and stubborn care product residues also respond to the solvent-based formula.
• Can be used on paint, glass, metal, and plastic. The formula is adapted to the requirements of common vehicle surfaces: painted, glazed, chromed, and made of thermoplastic. Safe on painted surfaces with short exposure time and without prolonged contact, more tolerant on glass and metal surfaces. The surface compatibility makes Stain Ex a versatile tool for adhesive removal without separate products for each surface.

Practical Tip from Detailing1: Apply Stain Ex precisely and sparingly — spray onto a clean microfiber cloth or apply directly to the adhesive spot, let it work briefly (30–60 seconds), then wipe. Do not spray large areas onto painted surfaces and do not use on hot paint — solvents can attack the clear coat at high temperatures and prolonged exposure times. Always test on an inconspicuous area first on delicate surfaces. After adhesive removal, treat the cleaned area with a mild cleaner or shampoo to remove solvent residues. For the removal of widespread tar contamination, we recommend the SONAX PROFILINE TarRemover as a specialized product for widespread tar removal.

Solvent Technology: How Stain Ex Dissolves Adhesive and Stubborn Stains

The active principle of the adhesive remover is based on selective solvent chemistry: certain organic solvents have the property of dissolving plastic polymers (adhesives), hydrocarbon compounds (tar, bitumen, wax), and other organic compounds — thereby weakening the chemical bonds between the polymer chains, causing the substances to swell and then easily detach mechanically from the surface. This is the basic principle of all adhesive removers: the right solvent for the right type of adhesive.

Stain Ex is formulated as a broadband adhesive remover that dissolves a wide range of organic residues — from acrylic adhesives (often in factory labels) to solvent-based adhesives (in lettering films) to bitumen (tar) and candle wax. This versatility comes from a balanced solvent mixture that addresses different types of adhesives without being too aggressive for vehicle paints. Paint compatibility is good with short exposure times — caution is advised with long exposure times or on delicate special clear coats (e.g., matte paints, very thin clear coat layers).

An important aspect when using solvent-based adhesive removers is residue-free removal: Stain Ex is formulated not to leave any visible or tangible residues on the treated surface after wiping and brief evaporation. This is particularly important before applying a new film or sealant — solvent residues on the substrate would impair the adhesion of the new layer. A final cleaning step with a mild cleaner after adhesive removal ensures that the surface is truly clean.

The temperature dependence of solvent chemistry is another factor that experienced detailers consider when using adhesive removers: at low temperatures (below 10 °C), the dissolution reaction slows down, requiring longer exposure times; at high temperatures (hot paint in the sun, above 40 °C), the solvents evaporate too quickly and can leave aggressive reconcentrations on the paint. Optimal use occurs at paint temperatures between 15 °C and 30 °C — in the garage or in the shade. The solvent selectivity also means that the adhesive remover can be used on freshly polished surfaces without destroying the polishing performance — the organic abrasive carriers of the polish are dissolved, which can even be useful as a side effect during adhesive removal after a polishing job.

Correctly Applying Stain Ex — Targeted and Safe for Adhesive Removal

The application of the adhesive remover requires a targeted approach and respect for solvent chemistry. Step 1 — Preparation: Roughly wash the affected vehicle or surface to remove loose dirt that could cause scratches when wiping with the solvent cloth. Identify the adhesive spot and pre-clean any mechanically removable residues (e.g., peelable film pieces) — only then treat the adhesive residue, which remains as a film on the substrate, with Stain Ex.

Step 2 — Application: Apply Stain Ex to a clean microfiber cloth or a lint-free cloth — do not spray directly onto the paint if precise control over the sprayed amount is not possible. Place the damp cloth on the adhesive spot and let it work for 30–60 seconds — do not rub, but rather place and wait for the solvent to swell the adhesive. Then wipe with light pressure — the swollen adhesive will detach and remain on the cloth. Repeat the process for more stubborn residues.

Step 3 — Post-treatment: Rinse the cleaned surface with clear water or wipe with a mild cleaner (e.g., car shampoo with water) to completely remove solvent residues. Then dry the surface and check for complete removal of adhesive residues. If the spot is being prepared for a new film application or sealant, a panel wipe step with SONAX PROFILINE Prepare is recommended after adhesive removal to optimally prepare the surface for the new coating.

Application Areas of Stain Ex — Typical Adhesive Removal Situations

The SONAX PROFILINE Stain Ex covers all typical adhesive removal scenarios in the professional automotive sector. Factory labels and dealer stickers on new vehicles: New vehicles often come with price tags, type plates, and promotional stickers that need to be removed after delivery. The adhesive residue after peeling off these labels cannot be removed with normal washing — Stain Ex dissolves it residue-free.

Film removal after lettering: Company cars, vans, and lettered vehicles are reconditioned after the end of use or lease period. The adhesive residues from the film lettering are often widespread and stubborn — Stain Ex enables efficient, widespread processing. For very large areas (entire side panels), it is advisable to saturate a larger cloth and work in sections.

Tar and bitumen residues: Road tar, which is stirred up during driving in warm asphalt and adheres to sills, door undersides, and wheel arches, is a classic detailing problem. For extensive tar spots, the specialized SONAX PROFILINE TarRemover is suitable — for individual tar spatters, Stain Ex is also suitable and has the advantage that it also dissolves other contaminants in the area of the tar spots. Wax residues on rubber parts, stubborn polishing oil deposits, and insect remains that cannot be removed without chemical help also respond to the adhesive remover.

Other applications in professional operations: On vehicles with paint protection film (PPF) application, the removal of the positioning film often leaves adhesive residues on the cut edges — Stain Ex precisely removes these edge residues without attacking the freshly applied protective film itself, when used targeted and with controlled quantity. In interior detailing, the product dissolves adhesive residues from stickers on plastic trim, adhesive residues from removed tinting films on windows, and stubborn resin stains on smooth surfaces. The product design as a 1-liter spray bottle allows for direct, controlled application — either onto a cloth or, in justified exceptional cases, directly onto the adhesive spot if precise dosing is ensured.

Adhesive Removers Compared — Stain Ex in the Product System

In the professional detailing range, there are various specialized products for adhesive removal and contamination removal. The SONAX PROFILINE Stain Ex positions itself as a universal adhesive remover that dissolves a wide range of adhesive residues — without specializing in a single type of adhesive. Against specific contaminations such as tar, the PROFILINE TarRemover is specifically formulated and more effective; for mineral contaminations (lime, rust), acidic cleaners like the SONAX PROFILINE MultiClean Acid are the better choice.

Stain Ex fills the gap between special cleaners: As an all-rounder for organic adhesive and stain removal, it is the tool that detailers use when neither the wheel cleaner, nor the alkaline pre-cleaner, nor the glass cleaner has solved the problem. The "stain and adhesive remover" product category is an integral part of every professional detailing kit, because in everyday vehicle use, a variety of organic substances get onto surfaces that cannot be removed with standard cleaners.

Compared to household adhesive removers (e.g., based on petrol or ethanol), Stain Ex, as a professional product, offers the advantage of higher concentration with a lower risk of paint damage during short exposure times. Household products are often either too weak (ineffective against tough adhesive) or too aggressive for delicate vehicle paints. Stain Ex is developed as a compromise that provides reliable results in professional use with acceptable surface compatibility.

Buying SONAX PROFILINE Stain Ex — Packaging and Practical Recommendation

The SONAX PROFILINE Stain Ex is available in 1 liter and as a 2x 1 liter set. The 1-liter container is designed for regular professional use in detailing businesses: With targeted, economical application, one liter is sufficient for a great many individual adhesive removal operations — only a few milliliters are needed per adhesive spot or small label removal. The 2-pack set is ideal for businesses that frequently recondition vehicles with film lettering or regularly perform large-area adhesive removal.

For detailing businesses that permanently stock the product, we recommend including it in the standard cleaning kit alongside the TarRemover, wheel cleaner, and alkaline pre-cleaner — together, these products cover the entire spectrum of organic and inorganic vehicle contaminations. The adhesive remover is the solution for everything that cannot be removed with water or standard cleaners.

The cost-effectiveness of the product is clearly demonstrated in practical use: Since only very small quantities are needed per application — typically 1–2 ml per adhesive spot — one liter is sufficient for a very large number of individual applications. Compared to common household alternatives, the professional product quickly pays for itself due to its higher effectiveness and the smaller quantity required. Detailers who recondition vehicles daily particularly appreciate the reliable consistency: a professional adhesive remover that works reproducibly with every use saves working time and reduces the risk of rework due to incompletely removed adhesive residues.

In summary, the SONAX PROFILINE Stain Ex is the essential product for all situations where adhesive residues, stubborn stains, or organic contaminants appear on vehicle surfaces. Professional detailers value it as a reliable tool that consumes less than expected, is effective, and protects treated surfaces when used according to instructions.
