Tetrachloroethene is a manufactured chemical that is widely used in the dry-cleaning of fabrics, including clothes. It is also used for degreasing metal parts and in manufacturing other chemicals.
Perchloroethylene is used in aerosol formulations for the automotive aftermarket, particularly for brake cleaning, as well as water repellents for garments, spot removers and silicone lubricants. It can be used as an insulating fluid in some electrical transformers as a substitute for polychlorinated biphenyls (PCBs).
