Kitten Wash'n'Wax is a two-in-one product which combines a special blend of high quality cleaning agents and protective waxes. It removes heavy road grime and leaves a protective wax coating on your car as you wash. Ordinary household detergents often contain salt, which causes corrosion. Kitten's Anti-Rust formula inhibits rust forming while you wash your car. When used regularly, Kitten Wash'n' Wax creates a lasting shine and is also ideal for boats. Lasts up to 30 washes
