Resin Guard is a proprietary solution made up of a liquid base packed with robust extracts that act as protective barrier between your precious piece and the natural resin build up that occurs during your sessions. With Resin Guard, you can enjoy the pure flavors of your legal herb for longer than you would using regular tap water. We’ve run Resin Guard through dozens of different tests to ensure that the 100% food-grade formula is effective and up to par with the other products in Randy’s unmatched cleaning line. Simply add Resin Guard to your favorite piece just the way you would regular tap water and experience for yourself an amazing session free from nasty resin build up!
