Cleanse: The Prep Shampoo That Strips Everything but the Paint
Every ceramic coating failure story starts the same way: something was on the paint that should not have been there. Oils from an old dressing, leftover wax, traffic film, silicone residue from a shine product. The coating bonded to that layer instead of the paint, and it died months early. Then the coating gets the blame, when the wash before it was the real problem. This guide covers what a prep shampoo is, how a strip wash is different from your regular car shampoo, and when Cleanse is the bottle to reach for.
What Cleanse is
Cleanse is a purifying paint prep shampoo. It strips oil, traffic film, and road grime off paint or coated surfaces without the harshness of alkaline heavy soaps, and it rinses clean without leaving soap residue or silicones behind. What is left after a Cleanse wash is a genuinely bare surface, which is exactly what your next step needs, whether that next step is a ceramic coating, paint correction, or paint protection film.
It also washes safely while it strips. Modern surfactants deliver the deep clean, and intense lubrication keeps the wash media gliding instead of grinding, so removing everything from the paint does not mean marring it in the process. That combination is rarer than it should be: most strip washes get their cleaning power from harsh alkalinity, which is exactly what Cleanse was formulated to avoid.
Prep shampoo vs regular car shampoo
These are two different tools, and the confusion between them causes real damage. A maintenance shampoo, like our SiO2 infused Ceramic Snow, is designed to leave things behind on purpose: gloss enhancers, protection, slickness. That is what you want on a regular wash day.
A prep shampoo is designed to leave nothing behind. No gloss agents, no silicones, no soap film. Before a coating bonds, before a polishing pad touches the paint, before film adhesive meets the surface, that nothing is the whole job.
Why not just use dish soap?
The classic garage advice for stripping wax is a bucket of dish soap, and it is bad advice. Household degreasers were formulated for baked-on food, not automotive finishes. The harsh alkaline chemistry that cuts kitchen grease also attacks trim, dries out rubber, and offers your paint zero wash lubrication, which is how strip washes turn into swirl marks. And after all that risk, dish soap still leaves its own residues behind.
Cleanse solves the same problem the correct way: modern surfactants strong enough to strip traffic film and oils, lubrication rich enough to wash safely, and a rinse that leaves the surface bare instead of coated in soap film.
The four times to reach for Cleanse
- Before a ceramic coating. A coating is only as good as its bond, and its bond is only as good as the surface. Cleanse is step one of every coating prep, including our own UNO installs. Wash with Cleanse, then decontaminate, then coat.
- Before paint correction. Polishing over grime and old product contaminates pads, hides the true condition of the finish, and wastes your compounding work on a layer that was never paint.
- Before paint protection film. Film adhesive wants clean paint, full stop. Residue under film is permanent residue.
- Reviving a neglected ceramic coating. A coated car that stopped beading is usually a dirty coating, not a dead one. Months of road film and wash residue mask the ceramic underneath. A Cleanse wash strips the buildup and brings the water behavior back, no machine required.
How to do a proper strip wash
- Rinse the car thoroughly to knock down loose dirt before anything touches the paint.
- Wash with Cleanse using a quality mitt, working top to bottom in straight passes. The lubrication is doing the safety work, so keep the mitt loaded with suds.
- Rinse completely. Cleanse releases from the surface easily and will not cling as soap film.
- Continue your prep. If you are heading toward a coating, decontaminate next with the Clay Mitt and Fuego, then polish if the finish needs it. If you were reviving a coating, just dry and enjoy the beading you thought was gone.
How often should you strip wash?
Less often than you think, and exactly when it matters. A strip wash is an event, not a routine. On an unprotected daily driver, a Cleanse wash every few months resets the surface and clears the accumulated traffic film that regular shampoo leaves behind. On a coated car, reach for it when the water behavior changes: slower sheeting, lazier beading, a finish that feels grabby instead of slick. That change is buildup talking, and one strip wash usually answers it. And any time you are about to invest in the paint, a coating, a correction, film, the strip wash is mandatory, because everything you apply afterward lives or dies on that surface.
Cleanse questions, answered
Will a strip wash hurt my existing ceramic coating?
No. Cleanse cleans the coating without attacking it, which is exactly why it doubles as the revival wash for coatings that have gone quiet. It removes what is sitting on the ceramic, not the ceramic itself.
Does Cleanse replace decontamination?
It is the partner to it, not the replacement. Cleanse handles the chemical layer: oils, film, and residue. Mechanical decon with a clay mitt handles bonded contamination sitting in the paint. Full prep before a coating uses both.
How is the paint left after a Cleanse wash?
Bare, clean, and free of silicones or interfering residues. That squeaky, naked-paint feel is the confirmation that whatever you apply next is bonding to paint and nothing else.
Can I use it as my everyday shampoo?
You can, it is gentle enough, but on a protected car you are better served by Ceramic Snow, which feeds the protection instead of stripping toward bare paint. Cleanse is the specialist you bring in when the surface needs to start over.
Does it work in a foam cannon?
Use it however your wash process works best. The job description stays the same: deep clean, safe wash, nothing left behind.
