Residue free degreaser and metal surface cleaner. The first step in ensuring proper surface preparation before rust treatment or top coating. Removes brake fluid, grease, oil, wax and other contaminants on contact and evaporates quickly, leaving no residue. Contains no ozone depleting chlorinated solvents or CFCs. Ideal for use as a degreaser/cleaner on rusted metal or bare metal before application of 3x Chemistry’s rust converter, rust dissolver, rust blocker, and metal etch.
