You’ve probably faced the frustrating mess of trying to clean your oil paint brushes after a long painting session. It feels hard, sticky, and sometimes you think you might ruin your brushes forever. But don’t worry — cleaning oil paint brushes with mineral spirits is one of the best ways to keep your brushes soft and ready for your next masterpiece. In this article, you will learn exactly how to use mineral spirits to clean your brushes safely and well, so your brushes last longer and work better every time.
Prepare Your Workspace and Gather Materials
Before you start cleaning your oil paint brushes, it’s important to set up your workspace correctly. Cleaning brushes with mineral spirits needs some care because the liquid can smell strong and be harmful if you breathe it in too much or spill it. So, find a place with good fresh air, like near an open window or outside. Use a table or a flat surface covered with old newspapers or paper towels to catch any spills.
You will need a few things: mineral spirits (also called paint thinner), a glass or metal jar with a lid, paper towels or old rags, a brush comb or old fork to help clean deep into the bristles, and soap to wash the brushes after using mineral spirits. Make sure your mineral spirits are in a safe container with a tight lid because they evaporate quickly and can be dangerous near fire or heat.
Wearing gloves is a smart idea to protect your skin, and if you want extra safety, use a mask to avoid breathing in fumes. When your workspace is ready and all your tools are close, you can start cleaning your brushes properly without making a mess or harming yourself.
- Find a well-ventilated area for safety.
- Cover your working surface to catch spills.
- Gather mineral spirits, jar with lid, paper towels, and soap.
- Wear gloves and a mask if possible.
- Keep the mineral spirits in a sealed container when not in use.
Dip and Swirl Your Brushes in Mineral Spirits
Now that your area is set up, it’s time to clean the brushes with mineral spirits. Pour some mineral spirits into your jar, enough to cover the brush bristles but not so much that it will spill easily. Take one brush at a time and gently dip the bristles into the jar. Avoid pushing the handle into the liquid because mineral spirits can loosen the glue that holds the brush hairs together.
Once dipped, swirl the brush around slowly in the jar. You will see the oil paint starting to come off the bristles and float in the liquid. Keep swirling for a few minutes, but do not press hard or scrub because it can damage the brush hairs. If the paint does not come off easily, gently use your fingers or a brush comb to help remove the paint stuck deep inside the bristles.
Sometimes, if the paint is very thick or dried, you might need to repeat dipping and swirling in clean mineral spirits to get the brush fully clean. After cleaning one brush, wipe it on a paper towel or rag to remove any remaining paint and mineral spirits before moving on to the next brush. This step is important to avoid mixing dirty liquid with clean liquid and to keep your brushes in good shape.
- Pour mineral spirits into a jar.
- Dip only the bristles, not the handle.
- Swirl the brush gently to loosen paint.
- Use fingers or comb to remove stuck paint.
- Wipe the brush on a paper towel after cleaning.
Wash Brushes with Soap and Water After Mineral Spirits
Even though mineral spirits remove the oil paint, your brushes will still have some chemical residue that can harm the bristles if left on too long. That’s why the next step is washing your brushes with soap and water to make sure they are clean and soft again. Use warm water and a mild soap like dish soap or special brush soap.
Hold the brush under running warm water, then add some soap to the bristles and gently rub the brush between your fingers or on the palm of your hand. This helps get rid of the last bits of paint and mineral spirits. Keep washing until the water runs clear when you rinse the brush. Be careful not to pull or twist the bristles hard, or the brush will lose its shape.
Once cleaned, reshape the brush head with your fingers, so it dries properly. Use a clean cloth or paper towel to remove extra water. Let the brush dry flat or hang it with the bristles down. Avoid drying brushes with the bristles up because water can get inside the handle and cause the wood to swell or glue to loosen.
- Use warm water and mild soap.
- Rub the brush gently to remove residues.
- Rinse until water runs clear.
- Reshape the bristles carefully.
- Dry brushes flat or hanging bristles down.
Store Brushes Properly After Cleaning
After your brushes are clean and dry, how you store them is very important to keep them in good condition. Never just leave your brushes laying flat on a table or standing bristles up in a cup for a long time. This can bend the hairs or cause them to dry in a bad shape.
The best way to store your brushes is to keep them in a brush holder or container that allows them to lie flat or hang with bristles down. If you don’t have a special holder, a clean drawer or box lined with soft cloth can work too. Make sure your brushes are completely dry before storing them, or they might grow mold or the wood handles may get damaged.
If you paint often, clean brushes will last much longer, and your painting will look better because your tools work as they should. Remember, good care after cleaning is just as important as cleaning itself. By storing your brushes carefully, you avoid bending or breaking bristles and keep your brushes ready for your next painting session.
- Store brushes flat or hanging bristles down.
- Avoid leaving brushes bristles up.
- Use a brush holder or lined box.
- Ensure brushes are completely dry before storing.
- Proper storage helps brushes last longer.

Frequently Asked Questions (FAQs)
Is it safe to use mineral spirits indoors?
Using mineral spirits indoors can be safe if you take the right precautions. Always make sure the room is well-ventilated by opening windows or using a fan to move fresh air inside. Mineral spirits release fumes that can be harmful if breathed in for a long time. Wearing gloves and a mask adds protection. Avoid using mineral spirits near open flames or sparks because they are flammable. Keeping the container closed when not in use helps reduce fumes. If you follow these safety tips, you can use mineral spirits indoors without problems.
Can I use other liquids instead of mineral spirits to clean brushes?
Yes, you can use other liquids like turpentine, odorless mineral spirits, or brush cleaner products designed for oil paint. Turpentine is stronger but smells stronger and can be more harmful, so many artists prefer odorless mineral spirits for a milder smell. Some people also use vegetable oils to remove paint, but oils alone won’t clean brushes completely. Mineral spirits are popular because they clean well and evaporate quickly, leaving brushes ready for soap and water cleaning. Choose the cleaner that fits your needs and safety comfort.
Do I have to use soap after mineral spirits?
Yes, using soap after mineral spirits is important. Mineral spirits dissolve the oil paint, but they leave a thin layer of chemicals on your brush that can dry out and damage the bristles if not washed away. Soap helps remove these chemicals and any leftover paint. Washing with soap also keeps your brushes soft and flexible. Skip this step, and your brushes may become stiff and break faster. So, soap and water are a necessary follow-up to mineral spirits cleaning.
Is it okay to soak brushes in mineral spirits for a long time?
No, soaking brushes for a long time in mineral spirits is not a good idea. Prolonged soaking can loosen the glue holding the bristles in place and damage the handle wood. It can also dry out or weaken the hairs. Instead, dip and swirl brushes for a few minutes, then wipe or rinse them. If needed, repeat with fresh mineral spirits, but avoid leaving brushes sitting in the liquid for hours. Proper cleaning is gentle and short to protect the brush’s shape and strength.
Can I reuse mineral spirits for cleaning brushes?
Yes, you can reuse mineral spirits a few times, but it depends on how dirty the liquid gets. When you clean brushes, the mineral spirits pick up paint and become cloudy or thick. Once the spirits look very dirty or have settled paint at the bottom, it’s time to replace them. You can strain used mineral spirits through a cloth or coffee filter to remove large paint chunks and reuse it one or two more times. Reusing helps save money and reduces waste but remember that old mineral spirits eventually lose cleaning power.
Do I need special soap for cleaning oil paint brushes?
You don’t need very special soap, but using mild dish soap or brush cleaner soap is best. Dish soap is good at removing oils and is easy to find. Brush soaps are made to be gentle and keep bristles soft, especially if you paint often. Avoid harsh soaps that can dry out your brushes. The main goal is to remove mineral spirits and any paint left on the bristles while keeping them healthy for long use. Mild soap and warm water work well for most artists.
Is it necessary to dry brushes flat or hanging down?
Yes, drying brushes flat or hanging them bristles down helps keep their shape. Drying brushes standing bristles up lets water drip into the handle, which can cause wood swelling or glue to loosen. This damages the brush over time. Drying flat on a clean towel or hanging with bristles down allows water to drain away from the handle and keeps the hairs straight and soft. Taking this extra care means your brushes stay in great shape and last longer.
Can mineral spirits harm my skin?
Mineral spirits can irritate your skin if you touch them too much or leave them on for a long time. They can dry out your skin and cause redness or itching. It’s best to wear gloves when cleaning brushes with mineral spirits. If you get some on your skin, wash it off right away with soap and water. Avoid touching your face or eyes while using mineral spirits. Taking these simple steps protects your skin from harm while you clean your brushes safely.
