How to Clean a Cello Bow
When not treated properly, cello bows tend to wear out and break quickly. Rehairing a bow can happen monthly for people who wear out the hair often, but many people get a bow rehaired when it is merely dirty, or becoming caked with goop. Therefore there are some daily maintenance processes, some spot cleaning, and some infrequent washing. However, rehairing a bow is relatively inexpensive, so if you don't feel comfortable, take it to a professional.
