306 results about "Wet cleaning" patented technology

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 tetrachloroethylene (commonly called perchloroethylene or "perc"). Environmental groups and the United States Environmental Protection Agency 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.
