A clean brush means smoother strokes and a more enjoyable painting experience.

Your paint by numbers brushes are the unsung heroes of your masterpiece. They handle crisp lines, smooth fills, and tiny corners. With a little care, they stay soft, keep their point, and save you money over time. Here’s exactly how to look after them.

Why Proper Brush Care Matters

It’s not only about making brushes last. Good care improves results and keeps painting relaxing. For more foundational tips, check out our beginner's setup checklist.

  • Smoother results: Clean, soft bristles lay paint evenly without streaks.
  • Sharper detail: A tidy fine tip makes intricate sections easy.
  • Lower costs: Well kept brushes don’t need frequent replacements.
  • Better experience: No clogging, no fraying, just calm painting time.

Step-by-Step Brush Cleaning: During & After Painting

1. Cleaning During Your Session - The Two Pot Method

Stop paint drying in the bristles while you switch colours or pause. This technique is key to maintaining your brushes throughout your painting session, especially for more complex kits, as highlighted in our pro techniques guide.

  1. Two water pots: One dirty for the first rinse, one clean for a final rinse.
  2. Swish and tap: Swirl in the dirty pot, tap the base to loosen paint.
  3. Wipe: Blot on a paper towel or an old cloth.
  4. Final rinse: Dip in the clean pot to finish.
  5. Reshape: Use your fingers to bring the point back before the next colour.

2. Deep Cleaning After Your Session - The Soap Method

Give brushes a proper clean at the end of each session.

  1. Rinse well: Repeat the during-session steps to remove most paint.
  2. Mild soap: Use hand soap, dish soap, or brush cleaner. Add a small dab to your palm.
  3. Lather and swirl: Gently work the bristles into the soap down to the ferrule.
  4. Rinse clear: Use lukewarm water until no soap or colour remains.
  5. Reshape: Pinch to a point or flat edge.
  6. Dry flat or upside down: Lay on a towel or hang bristles-down to avoid water creeping into the ferrule.

Essential Brush Storage Tips

Clean and dry is step one. Smart storage keeps the shape intact.

  • Store horizontal or bristles-up: Never stand brushes on their tips.
  • Use a roll or holder: A brush roll, case, or cup protects from dust and bends.
  • Avoid crowding: Give each brush room so bristles don’t splay.

Common Brush Problems & Quick Fixes

Warm water can help coax frayed bristles back into shape.

  • Frayed bristles: Dip in hot (not boiling) water for a few seconds, reshape, let cool. For stubborn splaying, a tiny dab of hair gel can help. Rinse before use.
  • Dried paint in the ferrule: Avoid it with regular deep cleans. If it happens, work out gently with soap and water. Don’t scrape with tools.
  • Loose ferrule: If the metal wiggles, a small bead of super glue at the joint can secure it.
