Chemtech Shock Treatment is the powerful, concentrated degreaser that makes short work of heavy-duty cleaning. Gentle on the environment, its biodegradable, solvent-free formula is tough on dirt, grease and grime. Apply with a brush, sponge, spray, degreasing gun, or high-pressure washer. The concentrated formula gets to work fast, converting oil and grease into a water-soluble product that doesn’t contain the hydrocarbons associated with solvent degreaser. And because it’s water-based, it’s non-flammable, and safe to use on plastic, rubber and glass. You can also use it to clean most metals and alloys, and it won’t cause rust. Even workshop floors and driveways come up a treat.
