rubbing alcohol will probably do the trick...... i dont clean my bongs/pipes.... i like the resin.... makes my glass look pretty.... why would i want to get rid of the prettiness
Yea rubbing alcohol will work, but if you're set on buying a more commercial product than go to a headshop and pick up some 420. They might even sell it at other places. It's just a mix of alcohol, some salts, and some smell enhancing thing.
