Isopropyl Alcohol is chemically different from the "normal" Ethyl
Alcohol you find in Alcoholic beverages, rubbing alcohol etc. Usually
it is sold in a relatively pure form, containing little else.
Colloquially it's called "dead hairdresser" in Germany. (Well, both my
parents studied chemistry, I think it's just chemist slang).

Thanks, that's actually more info than I expected. And I agree Acetone
sounds like a bad idea, it's pretty unhealthy and it has a tendency to
dissolve more than just dirt, for example markings in permanent ink.
