Optimum Paint Prep is an excellent cleaner for removing polish or old wax before applying any of Optimum Coatings or any other coatings or waxes. A combination of mild solvents dissolves and removes all the contaminants and leaves the paint squeaky clean and ready for the final protection. DIRECTIONS: Simply spray Optimum Paint Prep on the surface to be cleaned and wipe off with a clean dry microfiber towel till there is no residue left. The paint should feel squeaky clean after this step. Repeat the process if needed.
