What does pH-neutral car wash soap actually do?

A pH-neutral (or pH-balanced) formula is designed to lift dirt without stripping existing wax, paint sealant, or ceramic coating. Most premium picks in this category, including the Chemical Guys Mr. Pink, P&S Pearl, Turtle Wax Pure Wash, and the Adam's lineup, advertise pH-neutral chemistry specifically so you can wash a protected car weekly without degrading the protection. Verified-purchase reviewers consistently cite this as the reason they pay more than for a basic detergent.
