How to Properly Clean and Preserve Expensive Paint Brushes
To clean a quality paint brush: 1) For latex paint, wash under lukewarm running water while combing bristles with a stainless steel wire brush comb to remove paint from the ferrule heel; 2) Wash with brush cleaner soap (The Masters or Murphys Oil Soap); 3) Spin excess water out inside an empty 5-gallon bucket using a mechanical brush spinner; and 4) Return the brush to its original cardboard keeper jacket to maintain sharp bristle alignment.

Why Paint Brushes Fray and Lose Their Edge
When paint dries inside the "heel" (where bristles enter the stainless steel ferrule), the hardened paint forces the outer bristles outward into an unruly splayed fan. Combing the ferrule heel during washing keeps the bristle core clean and preserves razor-sharp cutting-in edges for 10+ years.
