Cleaning Acrylic Paint Brushes: A Comprehensive Guide

As painters, we know how valuable good paintbrushes are to our artistic processes. A loyal and reliable brush will make each stroke a pleasure and reward us with a beautiful end product.

However, as we all know, brushes get dirty and clogged with paint over time, which can affect their performance and lifespan. Painting with a dirty brush will not only create unpleasant results but can significantly damage the bristles and lead to diminished life span.

Therefore, it is essential to take proper care of your brushes by cleaning them on a regular basis. In this article, we will be discussing the different types of brushes that exist and the best cleaning methods for each one.

Types of Brushes

Before we dive into the world of brush cleaning, it is essential to know the different types of brushes that exist. Generally, there are two primary brush types, namely synthetic paint brushes and natural fiber paint brushes.

Synthetic Paint Brushes: These brushes are made of nylon or polyester, which makes them attract and hold more paint as compared to their natural hair counterparts. Synthetic brushes are relatively more affordable and are an excellent option for beginners who do not want to break the bank.

Natural Fiber Paint Brushes: These brushes are made from natural hair or fiber. The most common materials used for natural fiber brushes include hog hair, sable, camel hair, or ox hair.

Natural fiber brushes are durable and possess excellent paint retention ability. These brushes can be quite costly, but they offer superior quality compared to synthetic brushes.

Now that you have an understanding of the different types of brushes available let’s talk about some recommended brushes for acrylic painting, which are easy to clean and maintain.

Using Acetone or Isopropyl Alcohol

Despite taking good care of your brushes, there will come a time when they get clogged and dirty with paint. At this point, you need to clean your brushes.

One of the most common and effective ways of cleaning acrylic paint brushes is by using acetone or Isopropyl Alcohol. The steps for this method include:

Step 1: Pour a small amount of acetone or Isopropyl alcohol into a cup.

Step 2: Dip the brush head into the solution. Make sure that the solution covers the bristles.

Step 3: Start rubbing the brush gently against a folded paper towel or a rag. Make sure that you follow the shape of the brush to avoid damage to the bristles.

Repeat the process until all the paint is removed from the brush. Step 4: Wash the brush with mild soap and water.

Repeat until all the solvent is removed. Step 5: Let the brush air-dry.

Do not dry them in direct sunlight as it can damage the bristles.

Acrylic Brush Cleaner and Preserver

Another effective method for cleaning and maintaining your brushes is by using an acrylic brush cleaner and preserver. There are many options for acrylic brush cleaners, but the most common ones are:

GENERAL PENCIL The Masters Paintbrush Cleaner: This cleaner is specifically designed to clean all types of paint from natural and synthetic brush fibers.

It works by dissolving dried acrylic paint and restoring paintbrushes to their original condition. It also conditions the bristles and helps prevent damage and breakage.

WINSOR & NEWTON Brush Cleaner and Restorer: This cleaner is perfect for those stubborn and dried-up acrylic paints that seem almost impossible to get out. It also works brilliantly on oil paints, making it perfect for artists working with both mediums.


In conclusion, maintaining and cleaning your paintbrushes is vital in ensuring they serve you effectively for years to come. To recap, the first step is to identify the type of brush.

Synthetic brushes are relatively easier to clean in comparison to natural fiber brushes. This is because their bristles are less delicate and can withstand harsh cleaning chemicals.

The second step is identifying the appropriate cleaning method for each specific type of brush. Cleaning with solvents like acetone or isopropyl alcohol and using an acrylic brush cleaner and preserver are two of the most effective ways of cleaning paintbrushes.

By following these steps and using the recommended brushes mentioned in this article, you can extend the life span of your brushes and create beautiful works of art without the hassle of dirty and clogged brushes.

Additional Cleaning Techniques

Even with regular cleaning, sometimes our brushes may still have hard-to-remove acrylic debris that seems to be stuck to the bristles. Fear not; there are additional techniques you can adopt for more thorough cleaning.

Hair Comb Method

The hair comb method requires a few materials that you probably already have in your home – a hair comb, mild soap, lukewarm water, and a little linseed oil. Linseed oil helps to dissolve the thick, sticky paint without harming your brush.

Step 1: Mix a small amount of mild soap with lukewarm water. Step 2: Dip the brush into the solution and swirl it gently for about 30 seconds.

Step 3: Rinse the brush thoroughly with water. Step 4: Put a drop of linseed oil on the bristles, and use the hair comb to work the oil into the bristles gently.

Work from the base of the bristles to the tips. Step 5: Rinse the brush again to remove the oil and any remaining paint.

Step 6: Lay the brush flat to dry. This method works best for brushes with synthetic bristles.

If you have natural bristle brushes, it’s best to use cleaning solutions that are specifically designed for natural fibers.

Trimming Brushes

Sometimes, no matter how careful you are, the bristles of your paintbrush can become damaged. This can happen due to prolonged use, hard scrubbing, or exposure to harsh chemicals.

When this occurs, it is best to trim them down. The steps to trimming down a damaged brush include:

Step 1: Look at the bristles and identify where they are damaged.

Step 2: Take a pair of scissors or a blade and cut the damaged bristles carefully. Step 3: Trim the bristles in a straight line, so that the brush end is even.

Step 4: Wash the brush to remove any loose bristles. Trimming your brush will make it perform better.

However, trimming too many bristles may make it less efficient in holding paint. Therefore, it’s best to avoid cutting too many at once.

Preventing Paint Build-Up and Brush Maintenance

Taking care of your brushes to prevent paint build-up prolongs their lifespan and can make the process of cleaning easier. Here are some tips that artists can follow to keep their brushes in good condition and reduce the need for deep cleaning.

Cleaning Brushes After Use

It is always essential to clean your paintbrushes immediately after use, especially if you are using water-soluble paints. If you leave them to dry, the paint can harden and make it difficult to clean.

You can follow these steps for quick cleaning:

Step 1: Wipe off excess paint from your brush using a paper towel or rag.

Step 2: Rinse the brush under running water, and let the brush circulate in it until the water runs clear.

Step 3: Pat dry with a towel, and lay the brush flat to dry.

Painting Schedule and Brush Conditioning

Another way to prevent build-up of paint on your brushes is to keep up with a painting schedule. This way, you won’t be leaving your brushes untouched for an extended period, allowing the paint to harden.

Additionally, it’s essential to condition your brushes to keep them supple and to help keep their shape. Brush conditioning is a straightforward process, and it can be done by following these steps:

Step 1: Apply a small amount of conditioning oil, such as baby oil, to the bristles.

Step 2: Use the tip of your fingers to carefully work the oil down to the base of the bristles. Step 3: Wipe any excess oil using a paper towel.

Step 4: Lay the brush flat with the bristles facing upwards to dry horizontally. Brush conditioning helps keep your bristles supple, which in turn helps them retain their shape for future use.


Cleaning and maintaining acrylic paint brushes is crucial to ensure a highly efficient tool that meets our artistic needs. The methods outlined in this article can help you maintain your brushes and extend their life span.

Additionally, preventing paint build-up primarily through washing brushes frequently after each use and conditioning the bristles will enable your brushes to perform optimally, and reduce the time and effort that goes into deep cleaning. By following these techniques, youll ensure that your brushes are always in excellent condition and ready to serve you in all your artistic endeavors.

Dried acrylic paint on brushes can be challenging to remove. However, with the right steps, you can make the process a lot easier.
