BE AWARE!
In Washington a high school sophomores science project about the chemicals that remain in drycleaned clothing prompted a university study. A Georgetown University professor assisted the student with this experiment. They sewed squares of wool, cotton, polyester and silk into the lining of several mens jackets and then had them cleaned in 7 different drycleaners who had no knowledge of the experiment.
The research team determined that perc stayed in the fabrics and that the levels actually increased with repeat cleanings, particularly in wool.
