Car Wash Shampoo

A car shampoo has one job most people never think about: lubrication. The surfactants encapsulate dirt particles and let your mitt glide over them instead of grinding them into the clear coat — that's the difference between a safe wash and a swirled one. pH-neutral shampoos are the maintenance standard (and mandatory on coated or waxed cars), while wash-&-wax formulas leave a sacrificial gloss layer behind. Concentration matters too: proper dilution ratios are chemistry, not suggestion.

Build your routine right: how to build a car wash kit that won't wreck your paint and why pH-neutral isn't the whole story on coated cars.
