(MONEY Magazine) – When you pay your dry-cleaning bill, do you sometimes feel you're being taken to the cleaners? Just wait. A proposed new Environmental Protection Agency regulation could add another 10% to your bill once it takes effect late next year. As part of the 1990 Clean Air Act, the EPA plans to restrict emissions from perchloroethylene -- ''percs'' for short -- a potentially toxic dry-cleaning solvent. Some cleaners will wind up spending $3,000 to $30,000 to install new nonventing machines or to retrofit their existing equipment. When the ) California environmental agency imposed perc regulations in its state 10 years ago, dry-cleaning prices there shot up an average of 17%, according to the International Dry Cleaners Congress, an industry trade group -- but those rules were stricter than the EPA's. So if you're already fed up with high cleaning bills, fight back. Switch to wash-and-wear.
