Tetrachloroethylene, also known under the systematic name tetrachloroethene, or perchloroethylene ( perc  or  PERC ), and many other names, is a chlorocarbon with the formula Cl 2 C=CCl 2.It is a colorless liquid widely used for dry cleaning of fabrics, hence it is sometimes called dry-cleaning fluid..It has a sweet odor detectable by most people at a concentration of 1 part per million (1 ppm). Worldwide production was about one million metric tons in 1985.etrachloroethylene is an excellent solvent for organic materials. Otherwise it is volatile, highly stable, and nonflammable. For these reasons, it is widely used in dry cleaning. It is also used to degrease metal parts in the automotive and other metalworking industries, usually as a mixture with other chlorocarbons.
