The most common form of dry cleaning uses a chemical called perchloroethylene (or "PERC"). Ninety percent of the industry uses PERC, and dry cleaning accounts for between one-third and one-half of all the PERC used in Canada. Typewriter correction fluid and shoe polish are among the consumer products that contain PERC. PERC has been designated under the Canadian Environmental Protection Act as a persistent, bio-accumulative chemical that is toxic to the environment. Short term exposure to PERC can cause adverse health effects on the nervous system. Contact with PERC in its liquid or vapour form can irritate the skin, eyes, nose and throat. Long term exposure to PERC can cause liver and kidney damage. PERC has been shown to cause cancer in laboratory animals that repeatedly breathed PERC in air.
