The Randy's Resin guard is surely the best product you can use in order to keep your bong clean. This is not your regular bong cleaner that everyone has. The Resin Guard by Randy's actually provides a different solution to the problem by preventing your glass from getting dirty in the first place. The way it works is it replaces the water in your bong and prevents resin build up, so your bong never gets dirty! We know this sounds crazy, but we have put it to the test here at Goldenleaf and it works.
