You probably know the pain of trying to clean a paint brush after using oil based paint. You want your brush to last, but the sticky paint just won’t come off easily. You don’t have to throw your brush away or buy a new one every time! You can clean it well with some simple steps, and your brush will feel almost like new again. In this article, I will show you how to clean an oil based paint brush the right way, using easy materials and clear steps that really work.
Gather All the Things You Need
Before you start cleaning your oil based paint brush, it’s important to have everything ready. This will make the cleaning process smooth and quick. First, you need some paint thinner or mineral spirits. These liquids help break down the thick, sticky oil paint.
Next, get a clean container that can hold the thinner and the brush. A glass jar or metal can works well. You will also want some paper towels or old rags to wipe the brush after cleaning.
Don’t forget to wear gloves to protect your hands from the strong chemicals in the thinner. Also, make sure you work in a well-ventilated area, like outside or near an open window, because paint thinner can smell strong and might make you dizzy.
Having the right tools ready helps you avoid mess and frustration. If you don’t have paint thinner, you can use mineral spirits or even a brush cleaner made for oil paints, but paint thinner is usually best and easy to find.
ou might also want a wire brush or an old toothbrush to help clean deep inside the brush hairs if the paint is very thick. Setting up your cleaning space with newspapers or old cloths will catch spills and make cleanup easier.
- Paint thinner or mineral spirits
- Clean container (glass or metal)
- Paper towels or rags
- Gloves for hand protection
- Well-ventilated workspace
- Wire brush or old toothbrush (optional)
- Newspapers or cloth for workspace
Remove Extra Paint from the Brush
The first thing you want to do when cleaning an oil based paint brush is to get rid of as much paint as possible before using any liquids. This step saves time and uses less paint thinner.
Take a piece of newspaper or old rag and gently wipe the brush on it. Try to pull the paint out of the brush hairs without smashing them. You want to keep the shape of the brush intact because a damaged brush won’t work well next time.
If there is very thick paint, you can use the edge of a paint can or a brush comb to scrape off the extra paint gently. Be careful not to pull too hard because you might pull out some hairs from the brush. If you skip this step and put the brush straight into paint thinner, the cleaning will take longer and need more chemicals. Taking a few extra minutes now helps save paint thinner and keeps your brush in better shape.
This step is simple but very important. Removing the thick paint outside the brush lets the thinner work better inside the hairs.
- Use newspaper or rag to wipe off extra paint
- Pull paint gently, keep brush shape
- Use paint can edge or comb to scrape thick paint
- Avoid pulling brush hairs
- Saves thinner and time in later cleaning
Soak the Brush in Paint Thinner
Now it’s time to clean the brush deep. Pour some paint thinner or mineral spirits into your clean container. The thinner should be enough to cover the whole brush head, where the paint is. Place your brush into the thinner and let it soak. Soaking softens the hardened paint inside the brush hairs and starts to dissolve it.
Leave the brush in the thinner for about 10 to 15 minutes, but you can soak longer if the paint is very thick or old. While soaking, the paint will slowly come off. Sometimes, you can gently move the brush around in the thinner to help the paint loosen up. Be patient in this step — rushing won’t help because oil based paint is tough to clean.
Make sure you keep the brush tip submerged but don’t leave the brush handle in the thinner too long because it can damage the wood or glue holding the brush hairs. After soaking, the brush will feel softer and easier to clean.
- Pour paint thinner to cover brush hairs
- Soak brush for 10-15 minutes
- Gently move brush in thinner to help loosen paint
- Avoid soaking brush handle to protect it
- Be patient to get the paint soft
Work the Paint Out of the Brush
After soaking, you need to clean the paint out of the brush hairs. Take the brush out of the thinner and gently press it against the side of the container to remove extra liquid. Now use your fingers or a brush comb to carefully pull the paint out from the base of the hairs to the tip. The paint should come off much easier after soaking.
If the paint still feels sticky, dip the brush back into the thinner and repeat the process. You can also use an old toothbrush or wire brush to gently scrub the base of the bristles where paint often hides. Be very gentle so you do not damage the brush hairs.
This step may take time, but it is the most important to get your brush clean. Work slowly and carefully, cleaning all parts of the brush hairs. When the brush looks clean and soft, you can stop.
- Press brush on container side to remove thinner
- Pull paint out from base to tip of hairs
- Use brush comb, fingers, or toothbrush for stubborn paint
- Repeat soaking and cleaning if needed
- Be gentle to avoid damage
Wash the Brush with Soap and Water
Even though you cleaned the paint with thinner, some oily residue will remain on the brush. To remove this, wash your brush with soap and warm water. Use a mild dish soap or special brush soap. Rub the soap into the brush hairs and use your fingers to clean deeply between the bristles.
Washing with soap removes paint thinner, oil, and dirt, leaving your brush fresh and ready for the next use. After washing, rinse the brush under warm running water until the water runs clear and no more soap or paint residue comes off.
Don’t use hot water because it can damage the brush hairs or loosen the glue. Warm water is perfect. After rinsing, gently squeeze out extra water with your fingers or a clean towel.
- Use mild soap or brush soap with warm water
- Rub soap deep between hairs
- Rinse until water is clear
- Avoid hot water, use warm instead
- Squeeze out extra water gently
Dry the Brush Properly
After washing, drying your brush the right way is very important to keep its shape and make it last longer. First, shake the brush to remove water. Then, gently press it on a clean towel or paper towel to soak up extra moisture.
Never dry your brush standing on its bristles because this can bend or damage them. Instead, lay the brush flat on a towel or hang it with the bristles pointing down. This helps the brush dry evenly and keeps the hairs straight.
Drying can take a few hours, so it’s best to clean your brush well before you stop painting. If you want to use it soon again, make sure it is completely dry before dipping it into paint.
- Shake off water
- Press brush gently on towel to remove moisture
- Lay flat or hang with bristles down to dry
- Avoid standing brush on bristles
- Let brush dry completely before next use
Store Your Brush for Next Time
Once your brush is clean and dry, storing it properly keeps it ready for the next paint job. Keep your brush in a dry place where it won’t get dusty or crushed. Some people like to wrap the brush in paper or plastic to protect the hairs.
If you have a brush holder or case, use it to keep the brush’s shape safe. Avoid storing brushes standing on their bristles or in places with high humidity because this can damage them.
Taking care of your brush after cleaning will save you money and frustration. A good brush can last many years if you clean and store it right after every use.
- Store brush in dry, dust-free place
- Wrap in paper or plastic if needed
- Use brush holder or case
- Avoid standing on bristles or humid places
- Proper care saves money and keeps brush good
Clean Up and Dispose of Materials Safely
After you finish cleaning your brush, you have to clean up your workspace and dispose of paint thinner safely. Never pour paint thinner down the drain or on the ground because it is harmful to the environment. Instead, pour used paint thinner into a sealed container and take it to a hazardous waste disposal site or a local recycling center.
Throw used paper towels or rags carefully because they can be flammable. If you want, you can let used thinner sit in a jar so the paint solids sink to the bottom and clean thinner stays on top to reuse next time.
Cleaning up carefully keeps your home safe and helps protect nature. Always wash your hands well after working with chemicals.
- Do not pour paint thinner in drain or ground
- Store used thinner in sealed container for safe disposal
- Take to hazardous waste or recycling site
- Dispose of oily rags carefully, they can catch fire
- Wash hands after cleaning
- Reuse thinner after solids settle if possible

Frequently Asked Questions (FAQs)
Is it possible to clean an oil based paint brush without paint thinner?
Yes, it is possible but not very easy. Paint thinner or mineral spirits work best to break down the thick oil paint. Without thinner, you might try using a special brush cleaner made for oil paints, but it usually takes longer and may not clean as well. Some people try using vegetable oils or turpentine, but these can be messy or less effective. If you don’t have thinner, cleaning might take more time and effort, and the brush may never feel as clean as with thinner.
Can I use water alone to clean an oil based paint brush?
No, water alone won’t clean oil based paint from a brush. Oil paint does not dissolve in water because it is made with oil. You need a solvent like paint thinner or mineral spirits to break down the oil paint. After using the solvent, you can wash the brush with soap and water to remove leftover chemicals and oils, but water by itself will not remove oil paint.
Do I need to wear gloves when cleaning an oil based paint brush?
Yes, it is very important to wear gloves when cleaning with paint thinner or any solvent. These chemicals can irritate your skin, cause dryness, and be harmful if absorbed through your skin. Gloves protect your hands and make cleaning safer and more comfortable. Also, working in a well-ventilated area is important to avoid breathing in strong fumes.
Is it okay to leave my brush soaking overnight in paint thinner?
It’s better not to soak your brush overnight. Long soaking can damage the brush handle or loosen the glue holding the hairs. Soaking for 10 to 15 minutes is usually enough to soften the paint. If the paint is still hard, you can repeat the soaking process with fresh thinner, but avoid soaking for too long at one time to protect your brush.
Can I reuse paint thinner after cleaning my brush?
Yes, you can reuse paint thinner if you handle it properly. After cleaning, let the used thinner sit in a sealed jar for a day or two. The paint solids will sink to the bottom, and you can carefully pour off the cleaner thinner on top to use again. This saves money and reduces waste. Remember to store used thinner safely and dispose of paint solids properly.
Do I have to wash the brush with soap after using paint thinner?
Yes, washing the brush with soap and warm water after using paint thinner is important. Paint thinner cleans the paint but leaves oily residue behind. Soap removes this oil and any leftover chemicals, making the brush clean and soft. Skipping soap wash can leave your brush sticky or stiff and damage it over time.
Is drying the brush properly really necessary?
Yes, drying the brush correctly helps keep its shape and quality. If you dry a brush standing on its bristles, the hairs can bend or get damaged. Laying it flat or hanging it with the bristles down keeps the hairs straight and ready to use next time. Also, drying removes moisture that could cause mold or damage the brush glue.
Can I store my brush without cleaning it right after painting?
It is not a good idea to store a brush with oil based paint on it. The paint will harden and ruin the brush. If you want to take a short break, wrap the brush tightly in plastic wrap or aluminum foil to keep it from drying. But always clean the brush as soon as you finish painting to keep it in good shape.
