The Brush Cleaning Guide: Preserve the Lifespan of Your Oil Paint Brushes

It’s difficult to imagine painting without oil paint brushes, right? These brushes help us paint our masterpieces with precision and detail, but owning a good set of brushes doesn’t come cheap.

Keeping them clean and well-maintained is crucial to preserving their longevity. In this article, we’ll explore the importance of cleaning oil paint brushes and providing tips for maintaining them.

We’ll also discuss how to clean water-mixable oil paint brushes and the benefits of using specialized brush cleaner products.

Importance of Cleaning Oil Paint Brushes

Clean brushes are essential to the longevity of your painting tools. If left uncleaned, oil paint can harden on the bristles, making them difficult to use and causing damage.

Not only will the brushes lose their shape and texture, but they’ll also start to lose their hairs, which will quickly render them unusable. With every stroke, oil paintbrushes pick up dirt, grime, and other impurities, starting to contaminate the next color used.

In the end, the accumulated crud on your paintbrushes can produce unpleasant, muddy colors. Therefore, keeping your brushes clean and free of paint buildup is crucial for maintaining a pure palette that inspires the proper balance and value.

Tips for Maintaining Brushes

The following tips will help you maintain your brushes and extend their useful life:

1. Clean immediately after use: Always clean your brushes immediately after use to prevent paint from hardening.

Even if you’re taking a break from painting, avoid leaving paint-saturated brushes exposed for an extended time. Instead, wrap them in a wet paper towel or a plastic bag.

2. Wipe excess paint: Before cleaning your brushes, wipe away any excess paint on a rag or paper towel.

This avoids contaminating solvents or water with dry paint, so more time is required for cleaning. 3.

Use gentle soaps: Use gentle soaps instead of harsh ones like dish soaps. Put a small amount of soap into your palm and rub the brush bristles in a circular motion.

You can then rinse the brush and repeat the process if necessary. 4.

Avoid drying brushes vertically or tipping upwards: Drying brushes vertically or tipping them upwards disrupts the water and solvent balance trapped in the bristles. This can cause the bristles to bend and frizz, and soon becomes permanently damaged.

5. Store brushes correctly: Store your brushes by placing them horizontally or upside down in a container to prevent damage to the shape of the bristles.

Cleaning Oil Paint Brushes with Water-mixable Paints

Water-mixable oil paints are a recent innovation that allows you to use oil paints without the need for harsh chemicals. However, cleaning these brushes is slightly different from regular oil paint brushes since water can be used instead of solvent.

To clean water-mixable paint brushes:

1. Rinse in water: Rinse your brushes in warm water for a few minutes to dissolve the water-mixable paint.

Gently use your fingers to massage the bristles and remove any remaining paint. 2.

Use mild soap: If the paint refuses to come off, use a mild soap, just a small amount, before rinsing again under warm water. 3.

Dry: You can remove excess water or soap by gently pressing the bristles against a clean towel. Once done, dry your brushes horizontally or upside down to avoid water pooling in the ferrule.

Using Specialized Brush Cleaner Products

There are specialized brush cleaners available on the market that are specifically designed to clean oil paint brushes and preserve their longevity. These products are an excellent way to clean oily brushes, sculpt brush hairs back into shape, and keep them healthy and flexible.

Most of these brush cleaners come in gel or liquid form and contain conditioning oils and solvents that soften the oils on your brushes. Then, the solution dissolves the pigment without breaking down the glue holding the bristles together.

To use specialized brush cleaners:

1. Apply to brushes: Squeeze some brush cleaner onto a paper towel or into a plastic container suitable for soaking.

2. Soak brushes: Soak the brushes in the cleaner solution for up to fifteen minutes.

3. Rinse and dry: Rinse your brushes in warm water and let it dry.

You’ll notice that your cleaned brushes feel like new again, soft and bouncy to touch.


Maintaining and cleaning our brushes is essential to paint with them and achieve the desired results. By taking care of our brushes, we can extend their longevity and preserve them, resulting in better-quality artworks.

For a more durable and clean brush, remember to follow the tips we provided and the special cleaning methodology that your particular brushes warrant. If you still aren’t confident cleaning your brushes after reading this article, consider investing in specialized brush cleaners to help you along the way.

Happy painting!

Cleaning oil paint brushes can be a frustrating and time-consuming experience. But, it is an essential process to ensure the longevity and durability of your brushes.

In this article, we will discuss the proper cleaning and maintenance of your brushes, focusing on cleaning oil paint brushes with solvents or oils and recommended products for cleaning brushes. We will also talk about a useful trick for cleaning dried paint brushes with vinegar and the proper way to dry and store your brushes.

Cleaning Oil Paint Brushes with Solvents or Oils

Solvents and oils are two of the most effective tools for cleaning oil paint brushes. They work by dissolving the paint and breaking down the binders that hold the pigment together.

The most commonly used solvents are mineral spirits, turpentine, and spike lavender. Whereas, oils such as baby oil or linseed oil are used as methods to condition the brushes.

To clean brushes with solvents or oils:

1. Squeeze out excess paint: Similar to cleaning brushes with water, wipe or squeeze out excess paint from the brush by using a paper towel or rag.

2. Dip the brush in solvent or oil: Fill a small container with solvent or oil, then dip the brush into it.

Swirl the brush around gently, making sure the liquid penetrates the bristles to dissolve any remaining paint. 3.

Rinse: Rinse the brush in warm water and repeat the process until the water runs clear. 4.

Dry: Dry the brush on a clean towel or hanging them up and allowing them to air dry. While these methods of cleaning are effective, they may pose a risk to the user’s health and safety.

As such, appropriate safety measures should be practiced, such as wearing gloves, opening a window or using a respirator while using these chemicals.

Recommended Products for Cleaning Brushes

Using specialized products for cleaning brushes can be a safe and effective alternative to solvents. These products are specifically formulated for cleaning and conditioning oil paint brushes.

Winsor and Newton’s Brush Cleaner and Restorer is one such product that is highly recommended. It is a non-toxic, biodegradable solution that is excellent at cleaning dried-on oil paint and restoring old, hardened brushes to their former glory.

Simply soak the brush in the cleaner for a few hours or overnight and rinse with warm water to remove the softened paint. Another useful product is Plantional’s Oil Paint Brush Cleaner Soap, which is also non-toxic and biodegradable.

This cleaner soap is great for restoring bristles flexibility and shape while effectively removing paint, gently without harsh chemicals.

Cleaning Dried Paint Brushes with Vinegar

Dried paint on a brush can be a nightmare, but it’s not impossible to remove. Vinegar is an effective and natural way to clean dried paint brushes and restore their natural texture.

To clean dried paint brushes with vinegar:

1. Boil vinegar: In a saucepan, heat some white distilled vinegar until it comes to a simmer.

2. Soak the brush: Remove the saucepan from heat and place the dried paintbrush in the solution.

3. Soak overnight: Allow the brush to soak overnight, ensuring that the bristles are fully immersed.

4. Rinse and dry: Once soaked, rinse the brush under warm water to remove any residual vinegar and residue.

Dry the brush as usual.

Drying and Storing Brushes

How you dry and store your brushes can have a significant impact on their longevity. The following tips will help you ensure that your brushes are dried and stored correctly.

1. Dry horizontally: Ensure that the brushes are dried horizontally to prevent the water from wicking up into the handles, which can lead to rotting and damaging the brush.

2. Keep the shape: Brush shape is critical, so reshape the brush after cleaning to prevent it from becoming misshapen.

3. Store properly: Consider using a protective case or storing the brushes in a clean dust-free vertical or horizontal container to prevent dirt or paint contamination.


Cleaning and maintaining your oil paint brushes can be time-consuming, but it’s necessary to preserve the longevity of your tools. It’s crucial to clean brushes immediately after use, use gentle soap or specialized products instead of harsh ones, and dry your brushes horizontally and store them properly in a storage container.
