After finishing a painting job, you might forget to clean your paintbrush right away. When you go to use it next time, you might find old paint stuck to the bristles. This can leave you wondering if acetone is a good option for cleaning it.
Yes, you can use acetone to clean paintbrushes, including those used with oil-based paints, acrylics, and other solvent-based materials. Acetone is a strong solvent that effectively breaks down and removes dried or stubborn paint from the brush bristles. Here’s a step-by-step guide on how to use acetone to clean your paintbrushes and some other tips to keep them in top shape.
How To Use Acetone To Clean Paint Brushes
Cleaning paintbrushes with acetone is straightforward but can be dangerous if you don’t take proper precautions. Here’s how you can do it:
1. Get a bowl, ideally made of stainless steel or another metal.
2. Pour enough acetone into the container to fully cover the brush bristles.
3. Soak the brush in the acetone for about 30 minutes to an hour if the paint is very hardened.
4. Take out the brush and use a paper towel to wipe off the leftover paint.
5. Optionally, wash the brush with warm water and soap.
6. Rinse thoroughly with water and let the brush air dry overnight before using it again.

Stay safe while using acetone by following these tips:
1. Use acetone in a well-ventilated area to avoid inhaling the fumes.
2. Wear protective gloves and glasses to protect your skin and eyes.

4. Avoid using plastic containers to soak acetone as it can damage them.
5. Store acetone in a cool, dry place away from children and other tools.
