It looks no different than the other dry cleaners that line Solano Avenue just a tiny shop wedged in next to the 7-Eleven, with a bunch of faded posters tacked to the walls and a little nook filled with bolts of brightly colored thread for tailoring and alterations. But Clean Living Cleaners is an "organic" dry cleaner; that means it doesn't use the solvent perchloroethylene, or "perc," which most dry cleaners use. Perc has been shown to cause cancer in lab animals at levels very close to those allowed in the workplace. It can also be a skin irritant, and in its vaporous form can irritate the eyes, nose, and throat. In high concentrations, it can cause liver and kidney damage. Over the past few years, Bay Area dry cleaners have begun to ditch perc and explore gentler processes. Clean Living Cleaners offers friendly service as well as a nonperc solvent that will help workers and customers alike breathe a little easier.
