What is trichloroethylene (TCE) primarily used for?

Trichloroethylene is primarily used as a degreasing solvent for metal parts in manufacturing. It’s a clear, colourless liquid that effectively dissolves oils and greases, making metal surfaces clean for finishing or assembly. This aligns with the description of “a clear colourless liquid used mainly for degreasing metal parts in manufacturing.” It isn’t a colored solid used as a solvent, nor a gaseous fuel additive, nor a type of paint—the other options don’t fit its main role. Historically common, its use has declined due to health and environmental concerns, leading to safer alternatives in many applications.
