P&S Pearl Auto Shampoo: The Showroom Wash That Protects Your Coating
P&S Pearl Auto Shampoo is a pH-neutral concentrated car wash from the Renny Doyle Double Black Collection. Engineered to lift dirt, traffic film and light contamination with a rich foam, it cleans your paint thoroughly without stripping the wax, sealant or ceramic coating you have already applied.
The high-foaming formula provides genuine lubrication so your wash mitt glides instead of grinds, protecting your clear coat from wash-induced micro-marring. The signature pearl-like fragrance is a small luxury that turns weekly maintenance into something you actually look forward to.
Why Detailers Trust Pearl Auto Shampoo
- pH-neutral chemistry: safe over wax, sealant and ceramic coatings, so every wash extends their life rather than shortens it.
- High lubricity: reduces wash-induced micro-marring by helping the mitt or pad glide over the paint.
- Dense, slick foam: hangs on vertical panels long enough to encapsulate and lift contamination before agitation.
- Concentrated formula: dilute at roughly 30ml per 5-litre wash bucket. A 950ml bottle delivers 30 plus washes.
- Eco-conscious formulation: biodegradable surfactants, gentle on hands without losing cleaning power.
- Made in USA: Renny Doyle Double Black Collection, formulated for show car detailers.
How to Use P&S Pearl Auto Shampoo (Two-Bucket Method)
- Fill one bucket with 5 to 10 litres of warm water and add 30 to 60ml of Pearl, then agitate to build foam.
- Fill a second rinse bucket with plain water and a grit guard.
- Rinse the vehicle thoroughly with a strong stream of water to remove loose dirt.
- Wash one panel at a time with a clean microfiber wash mitt, from top to bottom.
- Rinse the mitt in the second bucket between every panel to leave grit behind, then re-load with suds from the wash bucket.
- Rinse the vehicle thoroughly, then dry with a plush microfiber drying towel. Bead Maker as a drying aid here is the classic combo.
Foam cannon use: dilute 30 to 60ml of Pearl in a 1-litre foam cannon bottle, top up with water. Pre-soak the vehicle before contact washing.
Pro tip: wash in the shade when possible. Hot panels and direct sun cause shampoo to flash off and water to spot.

Frequently Asked Questions
Is Pearl safe over a ceramic coating?
Yes. The pH-neutral chemistry will not strip or shorten the life of a ceramic coating, sealant or wax. Pearl is specifically formulated for cars with an existing last-step protective layer.
How much Pearl should I use per wash?
For a 5-litre wash bucket, 30ml is the maintenance dose. For heavier dirt or larger buckets, go up to 60ml. In a foam cannon, 30ml per litre of solution.
Will Pearl strip my wax or sealant?
No. Pearl is pH-neutral and contains no degreasers or solvents that would attack last-step protection. If you want to strip wax before applying a new product, use a dedicated decontamination shampoo instead.
Can I use Pearl in a foam cannon?
Yes. Pearl produces dense, clingy foam in a foam cannon. Start at 30ml per litre and adjust to contamination level and cannon ratio.
What is the difference between Pearl and a regular car shampoo?
Most supermarket car shampoos are alkaline and contain degreasers that strip wax in a few washes. Pearl is pH-neutral, concentrated, and designed for vehicles that already have protective coatings.
Where is P&S made?
P&S Detail Products is manufactured in the USA by Appearance Technology Group (ATG). The Rag Company Europe is the official European distributor.
