What Is Rosin?

Bow rosin is made of tree sap combined with small amounts of other ingredients (or not), poured into molds, allowed to dry and harden, unmolded, and polished.

When to Get Professional Help...

For your bow

• Because playing eventually wears out the hair, your bow should be professionally rehaired at least once each year, and any time the hair has lost its bite (friction), is dirty and can’t be cleaned well enough, or has lost a lot of hair.

Extreme Enemies

Humidity and temperature extremes are your enemies because they can ruin your bow and instrument.

Protect Your Bow and Instrument

Your bow and instrument are delicate; handle them accordingly. Train yourself to be conscious of where the bow and instrument are and how you are handling them when they are outside the case.

Bow Bugs!

If your bow hair is getting brittle or breaking in the middle, bow bugs have infested your case. If your case has bow bugs, you will need to have the bow rehaired professionally, and you or the luthier will need to clean and disinfect your case. Then you should follow some easy steps to ensure that they don’t come back.
