How to Clean Acrylic Paint Brushes

Introduction

Acrylic paint dries quickly, which is great for projects—but not for your brushes. If acrylic paint is left to harden in the bristles, it can permanently damage them. Cleaning your brushes properly after each use keeps them soft, flexible, and ready for your next painting session.

What You'll Need

• Warm water

• Mild dish soap

• Brush cleaner or brush soap (optional)

• Paper towels or a clean cloth

• A small bowl or cup

• Comb or brush tool (optional)

Steps

Rinse the brush under warm water immediately after use to remove as much wet paint as possible.
Add a small amount of mild dish soap or brush cleaner to your palm or a bowl.
Swirl the brush gently in the soap, working the bristles to loosen the paint.
Rinse thoroughly under warm water and repeat until the water runs clear.
Gently squeeze out excess water with your fingers or a cloth.
Reshape the bristles and lay the brush flat to dry.

Alternative Methods

• Brush Soap: Specialized brush soaps clean deeply and condition bristles.

• Fabric Softener Solution: Mix warm water with a little fabric softener to soften dried paint.

• Isopropyl Alcohol: Helps remove stubborn dried acrylic (best for synthetic brushes).

What NOT to Do

• Don’t soak brushes upright in water—this loosens the ferrule and damages the handle.

• Don’t use hot water, which can warp bristles.

• Don’t scrub aggressively, as this can cause fraying.

• Don’t store brushes bristle-side down.
