Optimum Car Wash is designed to clean the toughest automotive grime while maximizing the protection of Optimum Car Wax. The rich foaming lather traps dirt and grime and rinses with cold water leaving a smooth, clean surface behind. Optimum Car Wash is very concentrated and using 1oz. or less per gallon of water provides the necessary cleaning and foaming. Some car wash products as well as automatic car washes can remove the UV protection and wax, leaving the clearcoat finish unprotected. Optimum Car Wash is designed to remove dirt and grime without removing the protectants of Optimum Car Wax, therefore maximizing its protection. Optimum Car Wash is also extremely gentle and very safe for consumers while containing only bio-degradable ingredients to make it safe for the environment as well.
