Best Car Shampoo: Reviewed and Ranked

Car shampoo is pH-neutral soap formulated to lift dirt without stripping wax or coatings — the opposite of dish soap, which is alkaline and degreasing and will strip protection in two washes. Reach for it for any contact wash on a car you actually care about. Look for high foam (it's lubrication, not just looks — it keeps grit from grinding into the paint), neutral pH, and concentrate that goes a long way. Pair with two buckets (one wash, one rinse), grit guards, a soft wash mitt, and a dedicated drying towel.
