Bulk Car Wash Shampoo
Bulk car wash shampoos for automatic and brush washes: high pH and low pH for two-step washing, coating-safe pH neutral, and a wash and wax shampoo.
Shampoo chemistry for automatic washes
High-volume washes clean in seconds, so the chemistry does more of the work than in a hand wash. Choose by wash type and by what is on the customers' paint:
- High pH car wash shampoo — alkaline, lifts road film and organic soil.
- Low pH car wash shampoo — acidic, removes mineral film; used after the high pH step in a two-step wash.
- pH neutral automatic car wash shampoo — coating-safe for cars with wax, sealant or ceramic coating.
- pH neutral shampoo — lemon-scented, for brush washes.
- Wash and Shine — a wash and wax shampoo that leaves gloss.
Two-step washing
Applying a high pH then a low pH product neutralises each other on the surface and removes both organic and mineral dirt with less mechanical contact. For coated or premium cars, run a pH-neutral programme instead. Finish with a drying agent or foam wax.
Planning quantities? The bulk car wash chemicals guide works through dosing and cars per can.
Is a high pH shampoo safe on paint?
Used at the correct dilution and rinsed before it dries, yes. It will reduce wax over time, which is why coated cars are better served by a pH-neutral programme.
