1) Always wash a new brush before you use it - this will help remove loose bristles, especially with bristle brushes.

2) If you need to leave your project for a while, put the brush into a plastic bag or wrap it with cellophane and add a rubber band around the handle. You can put it in the refrigerator if you need to take a short break. But, do not put your brush in the freezer.

3) Wipe off any excess paint onto a rag or paper towel before washing it.

4) Do not rest your paintbrush with bristles down in a cup of water. Avoid holding the brush head beneath the water with the bristles pointing upward, as this’ll push the paint down into the brush.
