Many a string player has asked, “Can I clean my bow hair?”
In all honesty, I’m not the best person to ask. Though some musicians clean their bow hair, in my view the process is either non necessary or non effective. Over a lifetime of playing, I’ve only felt the need to try it once or twice. Most busy musicians simply replace their bow hair at a regular interval.
Properly maintained, your bow hair will last quite a long time. But it isn’t intended to last the life of the instrument. So when your bow hair looks dirty, it is likely in need of replacement, not simply a cosmetic cleanup. The exception would be a minor smudge in a single spot, caused by your thumb rubbing against the bow hair.
Here are some best practices for bow hair:
– Use your rosin sparingly, and only when it is needed. Most people use too much too often, causing a snowy mess on everything.
– Apply rosin with moderate pressure and slow to medium speed strokes. Too much pressure/speed damages the hair
– Use a quality rosin. If your rosin cake looks brand new, hard or glossy after many uses, it’s probably junk
– Keep your grubby fingers (or the body parts) off the hair!! And remember to release tension in your bow when you’re not playing.
Now, if you are still determined to try and clean your bow hair, remember to remove the frog from the bow so that your cleaning agent isn’t anywhere close to the bow wood. Alcohol and water are not wood or varnish friendly!
