And I see while I was typing, lots of other folks said the same. Sorry. Should shut up now.I'm a newbie here, so maybe shouldn't get involved. But I have to this time. Drinking alcohol, like vodka, moonshine, etc, is Ethyl alcohol. Ok in moderation. But rubbing alcohol is Isopropyl alcohol, a poison. And as others have said, also contains other chemicals. You don't want that stuff in your pipes.
