SMR-810 is a general purpose degreaser aerosol that removes silicone, grease, wax, tar, road film and other contaminants. It can be used as a pre-cleaner before grinding and sanding surfaces. SMR-810 comes in aerosol cans containing 12 cans per case. To use, wash the area with soap and water, dry it, apply SMR-810 liberally, let it penetrate contaminants, then wipe the surface clean with a dry cloth.
