Wet cleaning refers to methods of professional cleaning that, in contrast to traditional dry cleaning, avoids the use of chemical solvents, the most common of which is perchloroethylene or "perc". Environmental groups have indicated that such alternative "wet cleaning" methods are better for the environment than perc, and proponents of wet cleaning state that these methods can be used without shrinking or otherwise damaging garments that typically require dry cleaning.
It is not the use of water that makes wet cleaning a safer method for cleaning clothes. Computer-controlled wet cleaning machines, special dryers, safe detergents and non-toxic spot removers are what make wet cleaning an environmentally sound method.
Wet cleaning machines have controls that allow them to safely and efficiently clean a wide variety of garments in water.
Detergents and spot removers are made of ingredients that are safer for workers and the environment, yet are as safe and effective at removing stains and odors as dry cleaning solvents. I.e., the equipment, the detergents used and the experts’ skills all contribute to successful wet cleaning.
According to the Environmental Protection Agency (EPA), wet cleaning is the most environmentally sensitive professional method of garment cleaning. It does not use hazardous chemicals, it does not generate hazardous waste, nor does the process create air pollution and it reduces the potential for water and soil contamination. The specialized detergents used in the wet clean process are milder than home laundry products.The recent data shows that in USA, Wet cleaning is used for cleaning of almost 75 % of all casual clothing and sportswear
