Step-by-Step Guide to Clean a Paint Brush with Mineral Spirits

Step 1: Remove Excess Paint

Start by wiping off as much paint as possible from the brush. Use a rag or paper towel to scrape the bristles against the edge of the paint can.


Removing excess paint reduces the amount of mineral spirits needed and speeds up the cleaning process.

Step 2: Pour Mineral Spirits into a Container

Fill a clean metal or glass container with enough mineral spirits to submerge the bristles of the paint brush. About one to two inches of liquid is usually sufficient.


Mineral spirits are flammable, so work in a well-ventilated area away from open flames.

Step 3: Soak and Swirl the Paint Brush

Dip the paint brush into the mineral spirits and swirl it around for 10-15 seconds. Press the bristles gently against the sides of the container to loosen the paint.


You’ll notice the mineral spirits turning cloudy as the paint dissolves. Repeat this step two to three times, using fresh mineral spirits if the liquid becomes too dirty.

Step 4: Wipe the Bristles

After soaking, wipe the bristles with a clean rag or paper towel. This helps remove any remaining paint and mineral spirits from the brush.


If the brush still feels oily or has paint residue, repeat the soaking and swirling process to thoroughly clean a paint brush.

Step 5: Wash with Soap and Water

Once most of the paint is gone, rinse the paint brush under warm water with a small amount of mild dish soap.


Gently massage the bristles to remove any leftover mineral spirits and paint. A paint brush comb can help clean deep into the bristles, ensuring no residue remains.

Step 6: Dry and Store the Paint Brush

Shake off excess water and pat the bristles dry with a clean towel. Reshape the bristles to their original form and hang the paint brush or lay it flat to dry.


Proper drying prevents the bristles from becoming misshapen, keeping your brush ready for the next project.
