If you decide to change rosin what do you do about the build-up on your bow? Can bow hair be cleaned?
I'm not planning to chuck my bow in the bath with the dog-shampoo but it must have my current horrid sticky rosin well rubbed into the hairs by now.
Or does it all really matter and wouldn't I be better off eating strawberries in the rain instead of worrying about my violin for the millionth time.....
Some people say that you should clean your bow hair before using a new rosin (they recommend using a light shampoo, protecting the stick, and cleaning he hair thoroughly before combing it straight and leaving it to dry for a day or so - then combing it again before use).
On my luthier's advice, I've always just taken a clean, lint-free cloth and wiped the bow hair a good few times (gently and avoiding touching it with my fingers) until the hair leaves no more white streaks on the cloth. Then I put my new rosin on. Seems to work for me, although my new brand of rosin is staying forever because I love it so much!
