Oil paint never dries in a brush the way acrylic does, which sounds forgiving until you realize what that means: pigment and oil sit deep in the ferrule, slowly stiffening the bristles if you only rinse the tips. Cleaning oil paint brushes properly is a three-stage routine: remove the excess paint, dissolve what is left with a solvent or oil, then wash out the residue with soap and reshape. Done every session, it keeps natural and synthetic brushes springy for years.
This guide covers the standard solvent method, a solvent-free method, how to rescue brushes with dried oil paint, safe disposal of dirty solvent and oily rags, and how to store brushes. We then review five Amazon products that make cleaning easier, from brush soap to odorless mineral spirits and a sealed brush washer.
Quick answer: Wipe excess paint onto a rag, swish the brush in odorless mineral spirits in a sealed brush washer such as the MyLifeUNIT stainless steel brush cleaner, then wash with a brush soap like General’s The Masters Brush Cleaner and Preserver and lukewarm water, reshape and dry flat. For brushes with dried paint, soak in a restorer such as U.S. Art Supply Brush Cleaner and Restorer.
What You Need
- Rags or paper towels for wiping excess paint.
- Odorless mineral spirits (OMS) or another artist-grade solvent, or a vegetable oil such as safflower for a solvent-free routine.
- A brush washer: a lidded jar with a coil or screen at the bottom so sludge settles below the brushes.
- Brush soap: a dedicated brush cleaner and conditioner, or a mild bar soap.
- Lukewarm water. Hot water can loosen ferrule glue.
- Somewhere to dry brushes flat or bristles-down on a hanging rack.
The Standard Method: Solvent, Then Soap
- Wipe. Squeeze and wipe as much paint as possible onto a rag, working from the ferrule toward the tip. The less paint you leave, the cleaner your solvent stays.
- Swish in solvent. Dip the brush into odorless mineral spirits in your brush washer and gently rub it against the coil or screen. Do not jam the bristles into the bottom.
- Wipe again. Blot on a clean rag. Repeat swishing and blotting until little color comes out.
- Wash with soap. Wet the brush with lukewarm water, work brush soap into the bristles in your palm, and gently massage near the ferrule where paint hides.
- Rinse and repeat. Continue until the lather runs clear or nearly clear. Some pigments, such as phthalos, may leave a permanent tint; that is normal.
- Reshape. Shape the tip with your fingers. Some brush soaps leave a light conditioning film that helps hold the shape.
- Dry properly. Lay brushes flat or hang them bristles-down. Never dry them upright in a jar, which lets water run into the ferrule.
The Solvent-Free Method
If you want to avoid solvents entirely, oil can dissolve oil. This method suits small spaces, classrooms and painters sensitive to fumes.
- Wipe excess paint onto a rag.
- Work a vegetable oil, such as safflower or sunflower, into the bristles, then wipe. Repeat until most color is gone.
- Wash thoroughly with brush soap and lukewarm water to remove the oil, which would otherwise go rancid or sticky.
- Reshape and dry flat.
Our full guide to cleaning oil paint brushes without solvent covers this method step by step, and our guide to cleaning oil brushes without odor compares low-odor options.
Cleaning Agents Compared
| Option | Speed | Odor | Notes |
|---|---|---|---|
| Odorless mineral spirits | Fast | Low | Most common studio solvent; still needs ventilation |
| Gum turpentine | Fast | Strong | Traditional; strong fumes and more irritating for many people |
| Vegetable oil (safflower, sunflower) | Moderate | Minimal | Solvent-free; must be washed out with soap |
| Brush soap alone | Slow for oil | None | Best as the final step after solvent or oil |
| Brush restorer | Slow (soak) | Varies | For rescuing brushes with dried paint, not daily use |
Whichever agent you choose, use the smallest amount that does the job. A shallow layer of solvent in a washer, refreshed by decanting the settled clear liquid, lasts far longer than a full jar that gets muddy in a day. The same goes for oil: a teaspoon on a saucer is usually enough to clean a handful of brushes.
Most painters settle on one of two routines: odorless mineral spirits followed by soap, or vegetable oil followed by soap. Both work well when the soap step is thorough.
Cleaning Between Colors During a Session
You do not need a full wash every time you switch colors. Wipe the brush on a rag, swish briefly in solvent or oil, and wipe again. Many painters keep several brushes going, one for darks and one for lights, to reduce cleaning during a session. Save the soap wash for the end of the day.
How to Rescue Brushes With Dried Oil Paint
- Soak in a brush restorer. Products designed for dried paint soften residue over minutes to hours. Afterward, work the softened paint out with a rag or old toothbrush and wash with soap.
- Brush soap and time. Some brush soaps can remove old dried paint if left on the brush for several hours; work and rinse, then repeat.
- Oil soak. Soaking stiff brushes in vegetable oil can soften partially dried paint; follow with a thorough soap wash.
- Know when to retire a brush. A badly hardened brush can become a good scrubbing or texture brush.
Safety: Ventilation, Solvent Reuse and Oily Rags
Ventilate
Even odorless mineral spirits release vapors. Paint and clean in a ventilated room, keep containers closed when not in use, and keep solvents away from children and pets.
Reuse your solvent
Let used solvent sit undisturbed in a closed jar. Pigment settles to the bottom over days, and the clear solvent on top can be carefully poured into a clean jar and reused. This saves money and reduces waste.
Dispose of sludge responsibly
Never pour solvent or paint sludge down the drain. Let the sludge dry out in a well-ventilated area away from flames and take it to a household hazardous waste collection, following your local rules.
Handle oily rags carefully
Rags soaked with linseed oil or other drying oils can heat up as they cure and may catch fire on their own. Lay them out flat to dry outdoors or store them in a sealed metal container filled with water before disposal according to local guidance.

Buying Guide: Choosing Oil Brush Cleaning Supplies
Solvent or solvent-free
Odorless mineral spirits clean fastest; vegetable oil avoids fumes but needs a thorough soap wash.
A washer with a coil or filter
Lets sediment settle so brushes stay out of the sludge and solvent can be reused.
Sealed containers
Reduce fumes and evaporation, and prevent spills.
Conditioning soap
Keeps natural hair soft and helps all brushes hold their shape.
A restorer for emergencies
Worth having on the shelf for brushes left uncleaned.
Safety and disposal
Plan ventilation, solvent reuse and oily rag handling before you start.
Long-Term Brush Care
Store clean, dry brushes flat or upright with bristles up once fully dry, and protect fine points with their original tubes or a brush roll. Keep oil brushes separate from water-media brushes. For a complete care routine including storage and conditioning, see our guide to properly cleaning and caring for oil painting brushes.
Common Mistakes to Avoid
- Cleaning only the tips. Paint near the ferrule is what ruins brushes.
- Skipping the soap step. Solvent alone leaves residue that stiffens bristles.
- Hot water. Use lukewarm to protect the ferrule glue.
- Standing brushes in solvent. It bends tips and damages handles.
- Pouring solvent down the drain. Settle, decant, reuse and dispose of sludge properly.
- Balling up oily rags. Lay them flat to dry or store in a sealed metal container with water.
FAQs
What is the best way to clean oil paint brushes?
Wipe off excess paint, rinse in odorless mineral spirits or oil, then wash with brush soap and lukewarm water, reshape and dry flat.
Can I clean oil paint brushes with just soap and water?
Soap and water alone struggle to remove oil paint. Remove most of the paint with oil or solvent first, then use soap.
How do I clean oil brushes without solvent?
Work a vegetable oil such as safflower into the bristles to dissolve the paint, wipe it out, then wash thoroughly with brush soap.
How do I fix a brush with dried oil paint?
Soak the bristles in a brush restorer or leave brush soap on for several hours, work out the softened paint, then wash and reshape.
Can I reuse mineral spirits?
Yes. Let the dirty solvent settle in a closed jar, then pour off the clear solvent on top into a clean container.
Are oily rags dangerous?
Rags soaked in drying oils like linseed can self-heat and ignite. Dry them flat outdoors or store them in a sealed metal container with water.
Final Recommendation
A complete oil brush cleaning kit needs just a few items: odorless mineral spirits such as the Bellisinno 100 ml bottle (or a vegetable oil if you prefer solvent-free), a sealed washer like the MyLifeUNIT stainless cleaner, and a conditioning soap such as General’s The Masters. Keep the 1 oz Masters for travel and a bottle of U.S. Art Supply Restorer on hand for emergencies. Clean every brush fully at the end of each session, handle solvents and rags safely, and your brushes will last for years.
