So I have a small glass bong that is about a foot or a foot and a half tall. It is gross to say the least because I have no cleaned it in a while. I know that you can buy products at head shops, but is there anything I can buy at a hardware store that would still get the job done?
Salt and highest % rubbing alcohol you can find.....cover all holes and shake like a madman.....repeat as necessary. Should only take like 15-30min depending on shape and size.
