How to Clean Brushes Properly: Tips for Caring for Artist Brushes
Proper cleaning is essential if you want your artist brushes for watercolor, acrylic, or oil painting to retain their shape, spring, and paint-loading performance over time. Follow these basic brush care and cleaning guidelines:
1. Rinse water-based paints immediately
Water-based paints such as watercolor or gouache should be rinsed thoroughly from the brush with clean water as soon as possible. This prevents paint buildup and hardened bristles.
2. Remove acrylic paint while it's still wet
Fresh acrylic paint can be washed out easily with water. Once it has dried, only special brush cleaners or acrylic removers will usually be effective.
3. Remove oil paint mechanically first
For oil paints, first wipe excess paint from the brush with a cloth. Then clean it with a suitable brush cleaner if necessary.
4. Use a mild soap for natural hair, bristles, and synthetic fibers
Clean your brushes regularly with a conditioning soap made from vegetable oils in warm water until the lather turns white.
Avoid degreasing soaps, as they can dry out natural hair and make it brittle.
5. Clean the ferrule thoroughly
When washing the brush, gently work the bristles close to the ferrule. Pigment residues often collect there and can reduce the brush's flexibility and shape over time.
6. Reshape the brush
After cleaning, gently blot the brush with a soft cloth and reshape it to its original form. Artists often refer to this as dressing the brush.
7. Let brushes dry properly
Ideally, allow brushes to dry hanging with the bristles pointing downward. Direct heat, such as from radiators, can damage the hairs, bristles, and wooden handle and weaken the brush head.
