DRY CLEANING

During dry cleaning, the pump pulls solvent from the tank and sends it through the filters to remove any impurities. The filtered solvent then enters the cylinder, where it interacts with the fabrics and removes any soil. The solvent then travels back into the holding tank so it can begin the process again.

Dry cleaning still involves liquid, but clothes are instead soaked in a water-free liquid solvent, tetrachloroethylene (perchloroethylene), known in the industry as "perc", which is the most widely used solvent. Alternative solvents are 1-bromopropane and petroleum spirits.

Wearing dry cleaned clothing that was cleaned using perc exposes you to levels of perc that are slightly higher than what is normally found in the outdoor air, but these amounts are not expected to be hazardous to the average person's health.
