Acrylic paint brushes can last for years but only if you clean them properly. Acrylic paint dries fast, and once it hardens in the bristles, even expensive brushes can become useless. Whether you’re a beginner, hobbyist, or professional artist, knowing how to clean acrylic paint brushes correctly is essential for brush performance, paint quality, and long-term savings.
What Are Acrylic Paint Brushes?
Acrylic paint brushes are usually made with synthetic bristles, designed to handle the thick, fast-drying nature of acrylic paint. Unlike oil paints, acrylics dry through evaporation and polymer bonding, which means once the paint hardens, it becomes water-resistant and extremely difficult to remove.
Why Properly Cleaning Acrylic Paint Brushes Matters
Acrylic paint is water-based, but once it dries, it becomes water-resistant plastic. If paint dries inside the ferrule (the metal part of the brush), it permanently spreads bristles and ruins shape control.
Benefits of proper brush cleaning:
- Extends brush lifespan
- Maintains sharp points and edges
- Prevents paint contamination
- Saves money on replacements
- Improves painting precision

How to Clean Acrylic Paint Brushes (Step-by-Step)
Step 1: Remove Excess Paint Immediately

Pro tip: During painting, rinse brushes every few minutes to prevent paint from drying mid-session.
Step 2: Rinse with Lukewarm Water
Hold the brush with bristles pointing downward and rinse gently. This prevents paint from being pushed into the ferrule.
Avoid hot water it softens glue inside the ferrule.
Step 3: Wash with Soap
Apply mild soap or brush cleaner to your palm or brush mat. Gently swirl and massage the bristles.
Focus on:
- The base of the bristles
- Paint trapped near the ferrule
Repeat until suds are white, not colored.
Step 4: Final Rinse
Rinse thoroughly until water runs completely clear. Check by gently squeezing the bristles.
Step 5: Reshape and Dry Properly
Reshape the brush tip with your fingers. Lay brushes flat or at a slight downward angle to dry.
Never dry brushes upright with bristles facing up.
