Groove Juice cymbal and hardware cleaner: an advanced formula spray on, wipe off polish. This polish is a no-rubbing, no-buffing, and no-polishing polish that restores luster and keeps the tone brilliant. Fingerprints, dust, dirt, smoke, grime, etc. all collect and build up on your cymbals from daily use, causing your cymbals to oxidize. When oxidation occurs, part of your cymbal actually is destroyed and gone forever. That is the reason for cymbal pitting. Regular cymbal cleaning can cut down.
