Contrary to popular belief, dry cleaning uses a process that uses liquids or solvents other than water to clean garments, bedding, and other types of fabrics. Dry cleaning has significant advantages to improving the overall quality of clothing and other items by utilizing solvents to clean fabrics. Water can damage certain types of fabrics like wool or silk and that’s why dry cleaning is a chosen method versus at home laundering.
Dry Cleaners use a variety of solvents to clean different fabrics. Believe it or not, early dry cleaners used gasoline and kerosene to clean clothing which were very dangerous. Dry cleaners in the 1930’s began to change clean up the process and developed synthetic, nonflammable solvents — such as perchloroethylene (also known as perc or PCE) and decamethylcyclopentasiloxane (also known as GreenEarth) — which are still used today. In 1994 London Cleaners was the first dry cleaning company in Ohio to adopt the eco=innovative wet cleaning technology system and subsequently SystemK-4, organic dry cleaning solution.
There are many brands and models of cleaning machines, however, they are all very similar in design and function. “A cleaning machine is a motor-driven washer/extractor/dryer that holds from 20 to 100 pounds (9 to 45 kg) of clothes or fabrics in a rotating, perforated stainless-steel basket. The basket is mounted in a housing that includes motors, pumps, filters, still, recovery coils, storage tanks, fans, and a control panel. In all modern equipment, the washer and the dryer are in the same machine. Doing this makes it possible to recover nearly all of the perc used during cleaning, which is better for the environment and saves the dry cleaner money.” Source
