PCE Fact Sheet (pdf)

Able to dissolve most organic materials, perchloroethylene (PCE) is the most widely used dry cleaning solvent in Massachusetts and nationally. Its other major uses are as a metal degreaser, a chemical intermediate and an ingredient in consumer products, such as automotive aerosol parts cleaners and degreasers. PCE is reported to be the chemical most widely found in groundwater contamination at Superfund sites.
