Tips for Cleaning Acrylic Paint Brushes
How to Clean Acrylic Paint Brushes
Acrylic paint dries very fast. To preserve the health of your paintbrushes it is extremely important to:
- Keep the bristles moist at all times while painting.
- Clean brushes promptly at the end of each painting session.
Don't Let Acrylic Paint Dry on Brushes
Acrylic paint is easily washable with soap and water while wet, but, once dry, it becomes extremely difficult to remove.
If allowed to dry on the bristles, it can definitely ruin paintbrushes.
Act Fast, Time Is Money
Don't wait for the paint to dry to clean your brushes. Act fast, and focus on preventing any damages. As an artist, brushes are your working tools. You must keep them in good conditions so that they are able to do their job.
By cleaning your brushes thoroughly, you extend their life and, in the end, save a lot of money in supplies, by not having to replace them.
Keep Your Brushes Moist
During your acrylic painting session, make sure to rinse any residual paint from your brushes before putting them down and keep them wet just in case there is any unseen residue of paint near the ferrule, you don't want it to dry, or your bristles will spread out and lose their shape.
When you change color paint or you switch to another brush, remove any excess paint with a paper towel and rinse the brush thoroughly, then lay the wet brush flat until you need it again.
Avoid Getting Excess Water in the Ferrule
Avoid keeping your brushes soaked in water for a long time, because this could lose or rust the ferrule and damage the handle.
For the same reason, wet brushes should be left to dry horizontally, not bristles -up, or the water would drip down under the ferrule.
In general, you should never leave a brush standing on its hair for a long time, in water or during storage, because it may bend and lose its shape.
How to Wash Your Brushes in 10 Steps
- Remove most of the paint from of your brushes using a paper towel or a rag.
- Wet with warm water
- Load you wet brush with a mild soap. You can use any non-aggressive soap. Many people like to use Murphy’s oil, the household cleaner. I often use hand soap or a laundry soap bar. They also sell specific brush cleaning soaps.
- Rub the soapy brush on the palm of your hand, in circles.
- Create enough foam to take off all residues of paint.
- Massage the bristles with your fingers to get all the paint out from the middle of the hairs.
- Rinse thoroughly and repeat until foam and water are clear.
- Dry excess water with a rag, being gentle on the bristles.
- Flat dry, making sure that hairs are not pushing against any obstacles that may bend them.
- Once dry, store your brushes flat or bristle-up, to avoid bending of the hairs.

Environmental Tips on Washing Paint Brushes
Acrylic paint is not good for the environment, please avoid washing a big amount of paint down the drain. It is much better for the water system if you wipe off excess paint from brushes and your palette with a paper towel and throw it in the trash can.
Start cleaning by getting most of the paint off with a paper towel. Rub the bristles and the palette with some paper to collect as much paint as you can; then start washing.
More Tips on Washing Paint Brushes
- Use Mild Soap. Avoid dish detergent or other types of aggressive soaps.
- Use Soap Sparingly. Not to be cheap, but because even the mild soap could dry and affect the brush bristles, plus it takes longer and more water to rinse.
- Rinse Well. Make sure there is no soap residue whatsoever at the last rinse, or your first paint-stroke with that brush will be "soapy".
- Absorb Excess Water with a rag, being gentle on the hair of the brush.
- Lay Wet Brushes Flat. Flat is the best way for a brush to dry. Do not leave the brushes standing on their tip, this may damage the tip and compromise the shape.

Did you not clean your brushes in time?
Once acrylic dries, it really does become plastic, very hard to take off porous or textured surfaces.
However, there are some emergency solutions that I've heard of, and you might want to try if they work for you. Try soaking the bristles in ammonia, window cleaner, or even rubbing alcohol.
These methods will never restore them to be like new, but they might make them workable.
You may have success with some of these remedies, but be prepared to buy new brushes.
Questions & Answers
How should I remove old dried paint from the ferrules of brushes? Should I use Turpenoid?
If it's acrylic paint that dried on the ferrule, I would try soaking it with window cleaner and then rub it off with your fingernail.
For oil paint, I've got good results by soaking brushes with very dry paint in a cleaner by a company called Brush Flush. Everything cleans off like magic.Helpful 30
