How to Clean Your Oil Paintbrushes

Buying quality paint brushes can get expensive, so if you’re anything like me, you want your paint brushes to last you a long long time! Your oil paintbrushes are essential to your creative process, and proper maintenance can extend their lifespan and ensure they perform at their best. In this blog post, we will guide you through the steps to clean and preserve your oil paintbrushes effectively.

 

Materials You'll Need:

Odorless mineral spirits or a brush-cleaning solvent

Paper towels or rags

A container or jar for cleaning solvent

Mild soap


Step 1: Wipe Excess Paint

Before delving into the cleaning process, remove excess paint from your brushes by gently wiping them on a paper towel or rag. This step helps prevent excess paint from contaminating your cleaning solvent and simplifies the cleaning process.


Step 2: Clean Brush with Solvent

Fill a container or jar with odorless mineral spirits or a suitable brush-cleaning solvent. Make sure there's enough liquid to submerge the bristles of your brushes. Immerse your brushes into the solvent and swish them around gently. This will help dissolve the oil paint and separate it from the bristles.

If you accidentally left your brushes out for too long and have some dried paint on your brush, soak the brush in the solvent, swish, and attempt to remove paint with a paper towel. 


Step 3: Wash with soap and water

After cleaning your brushes in the solvent, rinse them under lukewarm water. Use mild soap to help remove any stubborn paint residues. Repeat the cleaning process with the solvent and rinse until your brushes are thoroughly clean and the water runs clear.


Step 4: Dry Properly

Drying your brushes is crucial to maintain their shape and prevent damage to the bristles. To do this, gently reshape the bristles to their original form and lay your brushes flat on a clean surface. Ensure they are well-ventilated, away from direct sunlight, and in a place where they won't be disturbed. If you have a brush rack or stand, use it to keep the brushes off surfaces, allowing them to air dry more effectively.


Optional Step: Condition Your Brushes


To maintain the softness and flexibility of your brush bristles, consider using a brush conditioner. This product helps restore and protect the bristles, preventing them from becoming stiff or frayed over time.


Frequently asked questions

Do I need to clean my brushes after every painting session?

While it's a good practice to clean your brushes after each session, it's not always necessary if you're continuing a painting within a short time frame. However, you should always clean your brushes thoroughly when you're finished with a painting session to prevent paint from drying on the bristles.


Can I clean my brushes without using a solvent?

Absolutely. Using a solvent is a very quick way to break down paint, though many artists like to avoid solvents because they can be harmful if ingested for long periods of time. 

To clean your brushes without a solvent, get a small container of oil that can be dirtied. Dip and swish your brush in the oil and wipe off with a paper towel. You may need to repeat this process a few times until the majority of the paint is off the brush. Then, follow the steps of washing the brushes with the mild soap. 


Can I use regular soap and water to clean oil paintbrushes?

Oil paintbrushes should not be cleaned with regular soap and water, as oil paint is not water-soluble. The preferred method is to use a solvent or clean with oil. 



Should I condition my brush with linseed oil?

No. Though linseed and other painting oils are completely safe for your brushes when painting, your brushes need time to be completely clean when not in immediate use. 


Taking care of your oil paintbrushes is an essential part of being an oil painter. By following the steps outlined in this blog post, you can ensure that your brushes remain in excellent condition, allowing you to create beautiful oil paintings for years to come. Remember that regular cleaning and maintenance of your brushes will not only save you money but also contribute to the quality of your artwork. Happy painting!
