Seattle's Blue Sky Cleaners freshens clothes without toxic chemicals | NWsource
Blue Sky Cleaners uses recycled and filtered carbon dioxide, combined with 700 pounds per square inch of pressure, to do its dirty work -- replacing toxic chemicals like perchloroethylene (PERC), which is used by most traditional dry cleaners and can contaminate ground and drinking water.
According to Callaghan, carbon dioxide is sustainable and nontoxic, and doesn't contribute greenhouse gases to the atmosphere. It is safe to inhale and is not harmful to employees.
