Violin Spit... it's a shocking name, but the fact is that most string players and fine violin shops will sometimes use human saliva to clean rosin build-up from instrument varnishes. This needs to be done each time you play your instrument because rosin is made up of 90% acid and should not be left to sit on your finish. Human spit is a very effective solvent but not the most sanitary way to clean! Our healthy, alternative formula has none of the nasty bacteria and cleans even more effectively. We use a slightly higher concentration of enzymes than in saliva, a natural organic surfactant (to lift the dirt), and a blend of natural food grade preservatives to protect the formula in a deionized water base. Try Violin Spit along with the Old Master Microfiber Cleaning Cloth (below), it's the most effective and gentle daily cleaner for string instruments. For a more aggressive occasional approach to remove rosin from your instrument bow and strings use Old Master String Cleaner & Rosin Remover.
