How To Clean Your Violin or Viola Bow
Clean the stick with a dry cloth
Tighten your bow, put a clean dry cloth between the wood (or carbon) and hair and wipe the rosin remains of. This is enough to do weekly and keep your bow nice and clean.
If you want to clean your bow more thoroughly, you can use a special fluid for stringed instruments.
Be careful that the fluid doesn’t stain on the bow hair. The best way to prevent it is to remove the frog from the bow (I explain how to do this safely in the video below). In this way you can separate the hair from the bow.
Only clean the stick of the bow with this fluid. Use just a little bit of fluid. Let the fluid dry before you put the frog back on your bow.
When your bow’s hair is dirty, you can clean it with alcohol
Often people think they need to rehair their bow when the bow hair is dirty. Often a good clean of the hair is enough.
Do this with a tooth brush with some alcohol on it. Brush the bow hair. Remove the frog from the bow first, so the bow hair is loose and separated from the bow. Make sure the bow hair is dry before you put the frog back on the bow.
The alcohol can damage the stick of your bow. Don’t do this too often as the alcohol will damage the core of the bow hair and makes it more vulnerable, which means you are in need of a rehair faster.
