You could simply toss the brushes into the bin; however, paintbrushes can be quite expensive, and you want to make sure you look after them. When it comes to cleaning oil paint brushes, it might be more of a process when compared to simply rinsing with water. When you clean oil paint brushes, most of us have used turpentine or thinners. However, there are other methods, and we will be taking a look at these as well as the traditional ways of cleaning oil paint brushes.

Types of Paintbrushes
Let us briefly consider the types of brushes available, not the shape or size but the actual make-up of a paintbrush. There are two main types of paintbrushes, the natural kind, and the synthetic brushes. Natural brushes have animal hair, are softer, and will manage oil paints better. Synthetic brushes are made from polyester or nylon, making them better for used with water-based latex paints. You can use synthetic brushes for oil painting, but using paint thinners or cleaners will affect the bristles.
Natural hair paintbrushes offer better quality, should last longer, and cost more than their synthetic counterparts. Then again, a synthetic brush will not last as long, but it is cheaper. When out shopping for brushes, you can check the quality of a brush simply by gently tugging at the bristles.
If you notice quite a few of the bristles coming off, rather search for another higher-quality brush. Sometimes paying a little more for something will save you in the long run. Today, you can most probably find a synthetic brush that can handle oil paints. Just make sure that when you make your purchase, it mentions that it is for oil paints.
Looking at the Best Ways to Clean Paint Brushes
There are a number of ways in which you can go about cleaning oil paint brushes. You can use chemicals such as turpentine or mineral spirits, go the natural route, or you can opt for at-home solutions by using household materials. We will look at all of these options in detail below.
Cleaning Oil Paint brushes with Turpentine or Mineral Spirits
Using turpentine or thinners is the more traditional method of cleaning oil paint brushes. While this method does work, there are a few disadvantages when using these products. One of the main problems is exposure to toxic fumes, which is something you do not want to do regularly.
Clean Oil Paint Brushes Using Turpentine
First, let us look at what turpentine is. This smelly fluid is obtained through a distillation process of resin from a pine tree. The resulting solvent is then used for thinning and cleaning oil-based paints. Turpentine also forms a part of varnishes and is used as a raw material for other purposes. A mixture of carnauba wax or beeswax and turpentine has been used as furniture wax for many years.
Unfortunately, turpentine is toxic and gives off a strong odor. The fumes can irritate the eyes, skin, and lungs if breathed in. Disposing of turpentine is also a problem – you cannot throw it down the drain, so you have to treat and get rid of it as hazardous waste. This is why many seek alternatives to turpentine that are safer to use and also better for the environment. Containers should also be properly labeled and stored out of reach of children.
First and foremost, when working with solvents you should always take your safety into account. So, wearing gloves and a mask is a good idea. Also, working in a well-ventilated space is important. Now, let us have a look at how to clean oil paint brushes using turpentine. You will need:
- Two small buckets or glass jars, depending on the size of your brushes
- Old rags
- Mild dish soap
- Paintbrush spinner (a handy tool available on Amazon; see product recommendations below)
You should clean your brushes straight after you are finished with them. The brushes should also not be soaked, as this could damage the bristles. You should always check the paint manufacturer’s directions for what type of paintbrush cleaner is best.
Step 1: Remove any excess paint by lifting and sliding the brush out along the paint can rim, or use an old rag or a piece of paper towel. You can also use newspaper to remove any excess paint.
Step 2: Here, you can use a bucket or glass jar. Fill this with some solvent and then dip or stir your paintbrush through the solvent. If working with turpentine or any other harsh chemicals, be sure to wear gloves. You can use your gloved fingers or a paintbrush comb to help remove any stubborn paint. Some recommend using the paintbrush spinner and then dipping the brush again into some clean solvent before spinning again.
Step 3: Fill the second bucket with some warm, soapy water and wash out any remaining paint. Shake the brush and dab lightly with a rag or onto the newspaper. Here, you can also use a paintbrush spinner, which will remove any water much more effectively.
Step 4: You can then gently re-shape the brushes and store them by hanging them up or keeping them flat on the surface. Once dry, you should re-wrap the brushes in their packaging or use heavy paper to wrap around the brush. This will help to keep the shape of the brush.
Note: Leave the turpentine or mineral spirits until all the paint solids have sunk to the bottom of the bucket or jar. Pour the rest of the solvent into another container. The paint solids should dry outside and then you can dispose of them as hazardous waste. Also, if you use rags when dealing with any of these cleaning methods, remember to dispose of these properly. If left, the used rags could be a fire hazard. Soak the rags in water and keep them in a sealed metal container before disposing of them properly.
Mineral Spirits and Cleaning Oil Paint Brushes
The actual cleaning process is similar to that of using turpentine, and the same goes for any other solvents used. How to clean dried paint brushes? Mineral spirits might also be a good choice to soften dried paint.
We are mainly going to deal with what mineral spirits are and compare them to paint thinners. Are these two the same and do they offer similar results? Mineral spirits come as a petroleum-based clear liquid that does not contain any additives and is not blended with anything else. This type of solvent is used as a paint thinner and cleaner, helping to clean fresh and unused paint.
Today, mineral spirits have been refined to be odorless, which is why it can be used in oil painting. Mineral spirits can be an irritant to the skin and lungs, however, it has fairly low toxicity. Since it is still a solvent and considered a hazardous material, it should be used with caution. Similar to turpentine, you should wear a mask and gloves, and work in a well-ventilated area. Mineral spirits are also known as paint thinners, but not all paint thinners are mineral spirits.
Paint thinner is a general term for the product’s function and does not refer to its composition. A paint thinner can contain any number of blended products, including mineral spirits, turpentine, naphtha, and acetone, amongst others.
Even if the paint thinner does contain mineral spirits, it is not the same as the refined mineral spirits with low odor and toxicity. Both the refined and blended mineral spirits do offer less odor and toxicity than most other paint thinners, however. The pure or refined mineral spirits cost you more than the blended paint thinners that contain additives.
Paint thinner, in general, can be used as an oil brush cleaner or to thin paint. However, mineral spirits seem to work better as a paint thinner due to slow evaporation. The thinned paint also dries smoother and more evenly when compared to other paint thinners that evaporate more quickly. Mineral spirits can also be used to remove substances like paint and tar from a variety of surfaces without causing damage.
How to Clean Oil Paint Off Brushes Naturally
When painting, you must regularly clean your brushes, as you do not want to expose yourself unnecessarily to toxic chemicals. Some may only use paint thinner or other harsher chemicals and find that these work best. However, there are other options when it comes to the best way to clean paint brushes.
Linseed Oil as an Oil Brush Cleaner
You can use any vegetable oil, but linseed oil is most commonly used to clean paint brushes. Linseed is an oil that can be found in most stores and is an affordable and less toxic option when it comes to cleaning oil paint brushes. There is no problem if you get any of the oil on your skin, however, you can still wear gloves if you have sensitive skin.
Linseed does not have a pleasant odor, but it is fine to breathe in. We still recommend that you work in an area that is well-ventilated. When you clean oil paint brushes, it should be done immediately after you have finished painting – do not leave the paint on the brush to dry. Read through the following steps to learn how to clean paint brushes with linseed or baby oil.
- Take a bowl for the linseed oil, and use enough oil so the brushes can be thoroughly coated.
- Stir the brush in the oil that is in the bowl, ensuring that the bristles have been thoroughly coated.
- You can also use your fingers to gently wipe from the base of the brush upwards, slowly and carefully.
- You can then paint or wipe on some newspaper.
- Fill another bowl with clean linseed oil and follow the same process.
- Blot the brush on some paper again.
- This might need to be done a couple of times until the oil runs clear on the paper.
- Finally, wash the brushes with some soap and water.
The same process can be done with baby oil, ending with washing the brushes with soap and water. Mineral oil is another oil you can use that you might already have in your home. Not only will it help to clean the paint brushes, but it can also disinfect them at the same time. You will need patience when cleaning oil paint brushes with linseed oil or any other oil, as it is not as quick and as effective as when using solvents.
Cleaning Oil Paint Brushes with Vinegar
Cleaning oil paint brushes with vinegar – can it be that simple? Yes, vinegar might be a great method of how to clean dried paint brushes. Vinegar is cheap and you should have some already somewhere in your kitchen cupboard. The process is fairly simple and is as follows:
- Pour some white spirit vinegar into a pot and heat. You can also heat in the microwave. The vinegar must be hot, not just warm.
- Pour it into a bowl or container and place the brushes in the vinegar. Try to hang the brushes so that nothing is touching the sides. This is to prevent the brushes from getting out of shape
- Leave for 20 minutes or wait for the paint to soften.
- Once they have soaked, rinse the brushes in some soap and water. Rinse properly to get rid of all the soap and paint – you can also use your fingers to gently remove any paint.
- You might have to repeat the process if necessary.
- Gently reshape the brushes and allow them to dry on a flat surface or hang the brushes up.
Clean oil Paint Brushes with Citrus Thinner
This product is made from extracting citrus oil and mainly comes from the juicing factory industry and its waste. The peel usually gets thrown out, but to prevent wasting this part, the citrus oils are extracted from the peel. It is then mixed with isoparaffin to make the citrus thinner. Even though it is non-toxic, it may cause skin irritation in some individuals. So, whenever working with any type of solvent, even if it is natural, remember that safety comes first. The method for cleaning oil paint brushes is the same as you would do when using mineral oil.
