How to Wash Oil Paint Brushes Step by Step
1. Wipe Off Extra Paint
Before you begin the process to clear oil paint from brushes, use a rag or paper towel to remove as much paint as possible. This helps reduce mess and makes cleaning easier.
2. Use Solvent to Break Down the Paint
To wash oil-based paint brushes, dip the brush into a container of odorless thinner or mineral spirits. Swirl gently to break down any stuck-on paint.
3. Rinse with Oil for a Gentle Clean:
For a softer method to clean oil paint from artist tools, rinse the brush in linseed or safflower oil. This step conditions the bristles while lifting leftover pigment.
4. Wash with Soap and Water
This is an important step in learning how to remove oil from paint brushes: use warm water and soap to remove all traces of paint and oil. Rinse well until the water runs clear.
5. Reshape and Let Dry
The final step in maintaining oil paintbrushes is reshaping the bristles and laying the brush flat or bristles down to dry. This keeps your tools in great condition for future use.
Dry the brush properly.
To prevent the ferrule from cracking or loosening, keep the handles dry.
Brushes should be dried horizontally or suspended vertically with their tips down. Excess moisture runs down into the ferrule if left to dry in an upright position with the hair ends up, causing swelling and chipping of the wood handle’s enamel finish.
Brushes should be stored upright in a well-ventilated location. Brush hairs must breathe, or they might eventually attract mold. Do not expose brushes to direct sunlight. Do not leave an environment that has moths.
How to Wash Dried Oil Paint Brushes
Dried oil paint can make a brush stiff, but it does not always mean the brush is ruined. With a little patience, you may be able to restore it.
Soften the Dried Paint
Soak the brush in odorless mineral spirits or a brush cleaner for a few minutes. This softens the dried paint inside the bristles.
Remove the Remaining Paint
Once the paint starts to loosen, gently work through the bristles with your fingers. Brush soap should be used to wash the brush, followed by a rinse with warm water. Repeat the process if necessary until the brush feels clean.
Common Mistakes to Avoid
Leaving Paint on the Brush
Avoid letting paint dry in a brush. The paint will dry in the heel of the brush, near the ferrule, making removal more difficult. This will cause the brush to lose its shape, brush hairs will fan out, and eventually, the brush will be unable to be used.
Using Hot Water
Hot water can damage the bristles and loosen the glue that holds them in place. Always use warm water when washing your brushes.
Storing Wet Brushes
Cleaning your brushes after each use stops paint from drying inside the bristles and keeps them ready for your next project.
Avoid Chemicals
When cleaning brushes, avoid using lacquer thinner, shellac remover, or acetone. These solvents can dissolve the glues, which hold the brush hairs in place.
Other substances to avoid for oil brush cleaning:
- Handwashing soaps
- Dishwashing liquid
- Baby oil
- Clove oil

Tips to Keep Your Oil Paint Brushes in Good Condition
Brush Care
- Do not dip a dry brush into oil paint. Dip the brush in painting medium before using it on natural hair. This distributes the natural oils of the brush hairs and allows each hair to load properly with paint.
- Different levels of the painting require different types of brush hair.
- Underpainting: Bristle or Synthetic: Requires vigorous brush strokes that have contact with the substrate (panel or canvas). Brush hairs get abraded through friction. Details are not as important. Avoid using expensive brushes or brushes with an extended point for mixing or scumbling paint. Use a palette knife for color mixing. Use an old or less expensive brush for scumbling.
- Middle layers: Bristle, High-Quality Synthetic, Mongoose
- Top layers: Sable, Mongoose, Bristle, High-Quality Synthetic. The final layer is seen the most. Detail and sensitivity most important
- Use one brush for white colors, one for yellows, one for reds, one for blues and greens.
- Each time you wash a natural hairbrush, you strip the brush hairs of natural oils which have to be replenished. Squeeze a small amount of brush conditioner into the palm of your hand, and roll the brush in it two to three times a year. Then rinse well. Reshape the brush by hand to its original shape and dry with a clean cloth or paper towel.
