Professional Wet Cleaning has been identified by the State of California and the respected Massachusetts’ Toxics Use Reduction Institute as a truly environmentally friendly, non-air polluting technology that is the safest choice for “Dry Clean Only” garments. In fact both states provide financial grants to dry cleaners to make the switch to wet cleaning. Wet Cleaning uses small quantities of water together with special detergents in computer-controlled machines. Once cleaned, the detergents and water are safe to flush down the drain. Other solvents require special handling and Perc residues have to be treated as hazardous waste.
