Chemical Guys Clean Slate Surface Cleanser Wash is a dedicated stripping shampoo rather than an everyday car soap, built to remove old wax, sealant and glaze so the paint is genuinely clean before claying, polishing or applying a new coating. The maker states a dilution of 1 oz to 5 gallons of water and describes it as a pH-balanced formula suitable for paintwork, glass, plastic, rubber, stainless steel, metal and aluminium. This 500ml bottle matches the maker's 16 oz size and works well with a dedicated bucket and wash mitt, kept separate from wheel cleaning tools. It fits naturally at the start of a paint correction or ceramic coating job, ahead of a clay bar, polish or panel wipe, rather than as a routine maintenance wash.
