Trichloroethene (also known as trichloroethylene or TCE) is a colorless, nonflammable, sweet-smelling liquid. TCE has seen extensive use as a solvent, especially for cleaning oil and grease from metal parts; it has also been used in paint and spot removers.

Trichloroethene is highly persistent in the environment, and sometimes shows up in groundwater around industrial facilities. This is especially unfortunate, as U.S. EPA and the International Agency for Research on Cancer have determined that TCE is carcinogenic to humans.
