Resin Demon Cleaner is the first and only cleaning solution that coats all those hard to reach places including percolators, down stems and your most delicate glass. Resin Demon is safe to use on all surfaces so there is no need for more than one bong cleaner. It contains no salt, isopropyl alcohol, acetone or other harsh abrasives. Resin Demon is the only national brand with a Material Safety Data Sheet which states “non-hazardous goods.”
