Did you ever stop to ponder what causes that icky dry-cleaning smell? The main chemical culprit is perchloroethylene, a central-nervous-system depressant and carcinogen known to cause skin irritation, dizziness, headache, confusion, nausea, liver and kidney damage, unconsciousness and death. Now, that's something we all want next to our skin, right? Revolution Cleaners wants to change the way we dry-clean our clothes: In place of the perilous perc, Revolution uses reclaimed, toxin-free liquid CO2, a chemical that's easier on the environment, your body, your nose and even your clothes. The cleaner also uses hemp laundry bags and wind energy in its stores and fills up its delivery vans with biodiesel. As Thomas Jefferson once said, "Every generation needs a new revolution." The shoe fits, and so will your sweaters.
