BENEFITS: A two-phase carburetor cleaner developed for easy cleaning of small parts. The solvent layer breaks up and suspends grease, baked-on carbon and oil, while the upper aqueous layer prevents solvent evaporation and dissolves water-soluble soils. Zepresto is non-flammable, and contains no carbon tetrachloride. It may be rinsed off with water; no solvent rinse is required.
