Nontoxic technology throws cold water on dry cleaning
by Kim Erickson
In the beginning there was soap and water. But over the years, we've increasingly
turned to dry cleaning to handle our laundry needs. This method (not really dry at all)
often involves submerging garments in perchloroethylene, or perc. Used by 80 to 85 percent
of the dry cleaners in the United States, this chlorinated hydrocarbon was originally
developed as a metal degreaser for airplane parts before the dry-cleaning industry adopted
it more than 50 years ago.
Classified as a hazardous substance by the EPA, perc has been linked to cancer,
neurological and reproductive disorders, and liver and kidney damage. Employees in
dry-cleaning plants are at particular risk. A 1994 study by the National Institute for
Occupational Safety and Health found that dry cleaners have seven times the average rate
of esophageal cancer and twice the rate of bladder cancer. Other studies link perc to
miscarriages and low birth weights among pregnant workers.
Until the 1980s, it was legal for dry cleaners to pour used perc down the drain.
According to a government survey, perc now contaminates up to 25 percent of U.S. drinking
water. The 35,000 dry-cleaning establishments in the United States and Canada use about
300 million pounds of perc annually, recycling less than 5 percent, leaving most of the
rest to evaporate into the atmosphere.
People living near a dry cleaner are exposed to high levels of perc as its vapors
invade their homes. Just having your clothes dry-cleaned can expose you to unhealthy
levels. Hung in your closet, these garments release residual perc into your home.
Consumers Union found that people who wear freshly dry-cleaned clothing once a week are at
an increased risk of developing cancer.
Fortunately, an alternative is catching on. "Wet cleaning" uses water,
nontoxic soap, and special washers and dryers that are calibrated to safely clean a broad
variety of materials, including leather. And except for a few fabrics such as antique
satin, wet cleaning is comparable to dry cleaning in quality, price, and turnaround time.
Despite perc's health and environmental consequences, many dry cleaners are still
reluctant to shift to wet cleaning. Industry associations encourage them to meet emissions
regulations by purchasing newer perc machines, even though at $60,000 apiece they're more
expensive than equivalent wet-cleaning equipment. "Dry clean only" labels add to
the problem by raising the threat of liability if an alternative cleaning method damages
clothing. And, as Jonathan Grossman, owner of the Natural Valet in Huntington Beach,
California, points out, "Chemicals are easy. Wet cleaning is more labor-intensive
because each garment gets individual attention."
In 1992 the EPA created a partnership with the dry-cleaning industry that has resulted
in a voluntary reduction of perc use by half. However, the agency hasn't come up with any
clear-cut plan to phase out perc and has delayed publishing a risk-assessment report for
more than three years. Some states aren't waiting for industry volunteers or more
stringent federal regulations. New York, for instance, has banned dry-cleaning stores in
residential buildings, forcing the operations to either relocate or convert to an
alternative method of cleaning.
Until perc is completely phased out, there are steps consumers can take to limit their
perc exposure. The easiest is to avoid buying clothing that requires dry cleaning. Air out
your clothes and use a lint brush to cut back on trips to the dry cleaner. Remember that
some fabrics, such as cotton, linen, and certain silks, can be hand-washed in cold water,
despite manufacturers' dry-clean-only warnings. Or give wet-cleaning a try. Not only will
the planet breathe easier, but your clothes will smell a lot fresher.
