For special fabrics, sometimes only a drycleaner will do. Problem is, traditional drycleaning requires a toxic chemical called perchloroethylene (or perc) to clean garments. Fortunately, greener drycleaners — employing people- and planet-friendly methods — are on the rise. One eco-friendly alternative is wet cleaning, which uses water and safe detergents. Search for nearby locations at Professional Wet Cleaners or Ecovian. Another safer alternative is pressurized liquid CO2. Start your search here for cleaners using this method. GreenEarth Cleaning, the developer of yet another eco-drycleaning process using liquid silicone (liquefied sand), offers this list of affiliated drycleaners. One additional directory — NoDryClean.com — lists all types of green cleaners.
