PrestoSol is a great, non-alchohol product which completely and safely destroys all kinds of viruses, bacteria, funguses, and other pathogens on mouthpieces. It can be used for other disinfectant duties as well. It is based on the patented technology of Silver Dihydrogen Citrate molecules.  Freshens, disinfects, deodorizes, with a fresh Peppermint scent! There is no better disinfectant out there for this purpose! Spray, let sit for a few seconds, then wipe. SAFE
