@Frondeur They use a non-water liquid to wash your clothes. Probably solvents like carbontetrachloride or other stuff. They'll tumble air-dry or hang dry as needed. This is from memory 20+ years ago so idk if it's still accurate. If your stuff smells, the question is "like what" ? Oil/grease are the hardest thing to take out and do better with hand scrubbing and soap.
