Can someone explain to me how dry cleaning works...why are my shirts still smelly...
@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.

@BowsacNoodle @Frondeur Carbon tet is ridiculously toxic, so not likely that. Though it was used in canned fire extinguishers for a really long time.

@Vo @Frondeur True, but dry cleaners have a much higher rate of cancer than average. I wouldn't be surprised.

>Although rare, some dry cleaners might still use carbon tetrachloride for specific purposes or in niche applications, but this is not widespread or recommended practice.
looks like they mostly switched over by the 60s to PERC and petrochems
