Here we’ve collected many ways how to clean brushes after oil painting and prolong their life.

What artists really don’t like about oil painting is that it’s messy. Cleaning brushes, maintaining workspace neat takes much more efforts than when you work with watercolours or acrylics.

Rinsing in turpentine or white spirit, or mixture of both

Turpentine and white spirit are  quite different, when we’re talking about painting. However, when it’s about brush cleaning, we can treat them as the same substances. Technically, they just break up oil and that’s how your brush comes out clean and neat. As both turpentine or white spirit are toxic, never pour liquid into toilet bowl or sink. Recycle properly, when possible. If special disposal or recycling is not available, just pour liquid into a jar, fill it with paper towels or cloth enough to absorb most of the content, close your jar tightly and dispose.

Pro’s:

  • easy to get and use
  • cheap
  • can be used during painting process, as well as for final brush cleaning after use

Con’s:

  • very toxic
  • can be smelly
  • requires special disposal
  • can damage delicate hair (kolinsky or other soft hair)

Rinsing in vegetable oil

If you’re lazy and paint frequently, you can use just regular vegetable oil for cleaning your brushes. Fill a glass jar with with 2 inches of oil and simply rinse your brushes there. Remove paint residue with paper towel. To prevent brushes from hardening, keep your brushes immersed in oil until the next use. Oil can be reused as paint will simply settle down on the bottom of the jar. Make sure that your brushes are suspended and don’t touch the bottom of the jar with oil to prevent brush damage.

Pro’s:

  • easy to get and use
  • cheap
  • can be used during painting process, as well as for final brush cleaning after use
  • non-toxic

Con’s:

  • doesn’t clean your brush in full, so you should keep your brush soaked in oil all the time

Rinsing in vegetable oil and freezing

If you’re planning to make a long break between oil painting, or don’t want to keep your paintbrushes soaked in oil all the time, after rinsing your brushes in oil you can wrap them with a plastic bag and place in a freezer. 

Pro’s:

  • easy to get and use
  • cheap
  • can be used during painting process, as well as for final brush cleaning after use
  • non-toxic

Con’s:

  • doesn’t clean your brush in full, so you should keep an eye on your brushes

Cleaning with dish soap

As dish soap is a good degreaser, you can simple wash your brushes in it. After full cleaning, leave your brushes horizontally to dry completely before the next use.

Pro’s:

  • easy to get and use
  • cheap
  • non-toxic

Con’s:

  • can be used only after painting session
  • requires long time for full drying before the next use
  • doesn’t work for delicate brushes (kolinsky etc.)

Dry cleaning with paper towels

Some artists use just paper towels and wipe the brushes until they get completely dry and paint removed.

Pro’s:

  • non-toxic
  • can be used during painting process, as well as for final brush cleaning after use

Con’s:

  • requires a lot of paper towels, so this method is not environment friendly
  • doesn’t work for delicate brushes
