tetrachloroethylene

Tetrachloroethylene, also known as perchloroethylene or PERC, is a chemical solvent commonly used in dry cleaning clothes and degreasing metal parts. It is a colorless liquid with a mild, ether-like smell. While effective at removing oils and dirt, it can pose health risks if inhaled or absorbed through the skin over prolonged periods, potentially affecting the liver, kidneys, and nervous system. Because of these concerns, its use is regulated to minimize exposure, and proper safety measures are essential when handling it. Tetrachloroethylene is also considered a pollutant, and environmental controls are important in its production and disposal.
