Solvall is a ready-to-use, water-rinsable liquid, which easily removes coal tar sealer, asphalt sealer, crack sealer, roofing tar, matic, tack coat, or oil and grease from most washable surfaces. It can be safely used on tools, equipment, vehicles, sidewalks, flooring, siding, clothing and carpeting. Solvall will clean up fresh spills splatters and over-sprays, as well as caked-on messes.
