Explanation:
Dry cleaning is any cleaning process for clothing and textiles using a solvent other than water. The modern dry cleaning process was developed and patented by Thomas L. Jennings.[1]
Dry cleaning still involves liquid but is so named because the term 'wet' is specific to water; clothes are instead soaked in a water-free liquid solvent, tetrachloroethylene (perchloroethylene), known in the industry as "perc", which is the most widely used solvent. Alternative solvents are 1-bromopropane and petroleum spirits.[2]
Most natural fibers can be washed in water but some synthetics (e.g. viscose, lyocell, modal, and cupro) react poorly with water and must be dry-cleaned.
