DON'T TRY THIS WITH YOUR DRUMS
Not with your regular wooden drums, anyway. Otherwise you will DESTROY your drums. Guarenteed. For Fibreglass drums, however, it's perfectly fine to give them a bath. Because fibreglass won't absorb water, they are unaffected by moisture which often causes regular drums to crack / warp / detune. Fibreglass drums stay in tune no matter what. And in the meantime, all the metal parts are receiving their own vinegar bath in a little tub, too.
