What actually happens when you take something to be dry cleaned?
When you wash your clothes at home in the washing machine, water is the solvent used to do the cleaning. Water is cheap and easy to get, but water has some problems. Many types of fabric, for example, do not handle water very well. Woolen water don't mix, and then there are many types of stains that water isn't particularly good at removing. And then there's fading water in the chlorine it contains confide certain colors. In dry cleaning, a petroleum solvent is
used instead of water. It is dry only in the sense that it's not wet with water. Instead, it is wet with solvent. In the early days of dry cleaning, this solvent was often kerosene or gasoline deodorized. Of course, today the industry uses a solvent called perchloroethylene almost universally. The clothes are washed in this solvent inside a seal dry cleaning machine. Then the solvent is recovered in an extractor so that it can be reused and so that
it doesn't evaporate into the air and cause pollution. Once the clothes are cleaned, they're pressed so they look like new. There's a fair amount of controversy around perchloroethylene or PERK and its health effects. Some dry cleaners are now using liquid c O two instead.
