Chlorinated Brake Cleaner
Chlorinated brake cleaner is nonflammable; however, it is harsh on your skin and is known to be a possible carcinogen. It is made of two components:
This solvent -- also known as perchloroethylene -- is the primary ingredient in this kind of brake cleaner. It is used to remove materials from metal that are not water-soluble. This includes grease, oil, brake fluid and brake dust.
Carbon Dioxide is used as a propellant in the aerosol format of brake cleaners.
Non-Chlorinated Brake Cleaner
Comprised of different chemicals than chlorinated brake cleaner, this version is extremely flammable but is less harsh on your skin. It contains:
This chemical distilled from oil is used primarily as a solvent to clean contaminants from metal parts and is not water-soluble. It is safe for use on ABS brakes, as well as disc and drum brakes.
This solvent is used to clean contaminants from parts. It is particularly useful in removing water-based contaminants, as it absorbs water.
This gas is used as the propellant in non-chlorinated brake cleaner.
Non-chlorinated brake cleaner is flammable. Use it in a well-ventilated area away from open flames, hot surfaces and sparks. Do not smoke around brake cleaner.
