Non-Toxic Techniques for Cleaning Oil Paint from Brushes

Getting Started with Oil Painting
My childhood friend introduced me to the world of oil painting, and one of the biggest challenges I faced was cleaning the brushes. I recall using turpentine back in the day, which had a rather unpleasant odor. However, after picking up oil painting again this past year, I discovered a non-toxic way to clean my brushes effectively.
Understanding the Science
If you’ve studied chemistry, you might be familiar with the principle that “like dissolves like.” Unlike water-based acrylic paints, oil paints do not dissolve in water, making cleanup a bit trickier.
To tackle this, I prepared three empty glass jars:
- Jar #1: Contains a small amount of olive oil.
- Jar #2: A mixture of equal parts olive oil and dish soap.
- Jar #3: A blend of dish soap and water, also in equal amounts.
Step-by-Step Cleaning Process
Initially, I used a paper towel to remove as much oil paint as possible from the brush.
Then, I dipped the brush into Jar #1. The oil in the jar interacts with the oil paint, allowing some of it to lift off the bristles.
Next, I moved on to Jar #2. Here, the combination of olive oil and dish soap works together to dissolve even more paint from the brush.
This is where the unique properties of soap come into play. Soap molecules have both hydrophilic (water-attracting) and hydrophobic (water-repelling) ends, which allows them to interact with both oil and water.
Finally, I used Jar #3. Any remaining traces of oil paint that weren't removed in the first two jars can be cleaned off more easily now. The dish soap in Jar #3 works to dissolve the remaining paint, thanks to its ability to mix with both oil and water.
Do you oil paint? What methods do you use to clean your brushes?
