Professional Care & Maintenance
-
Avoid Acetone: Never use pure acetone to clean natural Kolinsky hair, as it strips the natural oils and makes bristles brittle. Use clear base gel or a dedicated brush cleanser.
-
Reshape the Edge: After cleaning, gently pinch the bristles into a sharp, flat angle to maintain the brush's specialized geometry.
-
Horizontal Storage: Always store your brushes horizontally to protect the fine hair and the integrity of the birch handle.
