Dryclean
Dryclean means a commercial process by which soil is removed from products or specimens in a machine which uses any common organic solvent (e.g. petroleum, perchlorethylene, fluorocarbon). The process may also include adding moisture to the solvent, up to 75% relative humidity, hot tumble drying up to 160 degrees F (71 degrees C) and restoration by steam press or steam-air finishing.
