In contract, most dry cleaners in use a petroleum-based solvent called perchloroethylene, which can be very hard on fabric.
More than 85% of dry cleaners still use perc today. Why? Because despite many significant attempts to find a suitable alternative, no workable solution could be found. Petroleum-based solvents may be hard on fabrics and harmful when not used properly, but they clean effectively and affordably, so dry cleaners have been reluctant to switch. Until now.
Perc, as it is called, is also classified as a Hazardous Chemical and is carefully regulated, both in how it is used and how it is disposed of.
