Kolinsky Acrylic Brush #12: How to Clean and Maintain

Quick Answer

Clean your Kolinsky acrylic brush #12 right after each use with monomer, reshape the bristles, and store it flat in a cool, dry place to keep it performing like new.

Step-by-Step Cleaning and Maintenance

1. Rinse in monomer immediately after use: Dip the bristles into monomer and gently swirl to dissolve wet acrylic. Do not let acrylic dry on the bristles—once it hardens, it is much harder to remove and can break the hairs. Never leave the brush sitting in monomer for more than a few seconds; prolonged soaking can swell the handle and loosen the ferrule.
2. Wipe the bristles on a lint-free cloth: After rinsing, wipe the brush from the ferrule toward the tip on a clean lint-free cloth or paper towel. This removes excess monomer and any remaining acrylic. Avoid pulling the bristles sideways, which can bend or split them. Check that no acrylic residue is left near the ferrule; buildup there is a common cause of splaying.
3. Reshape the tip with your fingers: While the bristles are still slightly damp, use your thumb and index finger to gently roll the brush to a point. This trains the natural Kolinsky hair to hold a fine tip for detailed lines. Do not use soap or water—water can damage the natural bristles and affect how the brush picks up acrylic.
4. Dry flat with the tip pointing down: Lay the brush flat on a clean surface with the bristle tip slightly lower than the handle, or use a brush holder that keeps the tip down. This prevents monomer from seeping into the ferrule, which can loosen the bristles over time. Never store the brush upright in a cup with the bristles down. Make sure the brush is completely dry before storing to avoid mildew or odor.
5. Deep clean weekly with brush cleaner: Once a week, use a professional brush cleaner or a small amount of monomer to break down stubborn acrylic residue. Gently work the cleaner through the bristles with your fingers, then rinse and reshape as above. If the bristles start to splay, a deep clean often restores them; if not, it may be time for a new brush.
