C-48 SHAMPOO & WAX does two jobs at the same time. It cleans and protects the car's finish while washing. C-48 is a thick concentrate (64:1) formulated to penetrate and lift away dirt and grime. Removes contaminants without the use of harsh chemicals or detergents. Wash & wax combinations often tend to film and streak, but not PRO Shampoo & Wax. This premium wash and wax is fortified with genuine auto wax. C-48 beads and separates, simplifying the removal of excess water. The formula will not harm existing wax or sealants already on the finish.
