Brake Cleaner Ingredientsby Jason Unrau
Brake cleaner is a skin and eye irritant. Don safety clothing and eyewear when using brake cleaner.
Brake cleaner is toxic. If ingested, contact a poison control center immediately. Do not eat or drink when using this product.
Chlorinated Brake Cleaner<p><strong>Chlorinated brake cleaner</strong> is nonflammable; however, it is harsh on your skin and is known to be a possible carcinogen. It is made of two components:</p>
Tetrachloroethylene<p>This solvent -- also known as <strong>perchloroethylene</strong> -- 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.</p>
Carbon Dioxide<p>Carbon Dioxide is used as a <strong>propellant</strong> in the aerosol format of <a href="http://crcindustries.com/auto/?s=05089">brake cleaners</a>.</p>
Non-Chlorinated Brake Cleaner<p>Comprised of different chemicals than chlorinated brake cleaner, this version is extremely flammable but is less harsh on your skin. It contains:</p>
Heptane<p>This chemical distilled from oil is used primarily as a <strong>solvent</strong> 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.</p>
Acetone<p>This solvent is used to clean contaminants from parts. It is particularly useful in removing water-based contaminants, as it absorbs water.</p>
Carbon Dioxide<p>This gas is used as the propellant in non-chlorinated brake cleaner.</p>
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.
