Oil-based paints are very stubborn and difficult to remove. Therefore, it is preferable to use acrylic paints for the base layers of paint since they are water-based and easy to remove from brushes.

One of the simplest techniques for cleaning oil paintbrushes without using any solvent is to remove any leftover paint on the brushes with a paper towel or cloth immediately after use.

2. Use Solvents and Thinners

Solvents like mineral spirits and paint solvents are the most common brush cleaners for oil paints. When using these solvents, make sure they are safe for oil paints. A tip for the safe use of mineral spirits or paint solvents is to carry out the process in an open, ventilated area because they are toxic if inhaled.

  • Pour a small amount into a container and dip your brushes in it.
  • Swirl them around to ensure the solvent penetrates the bristles.
  • Repeat the process until the brushes are cleaned thoroughly.
  • Do not soak for long because these solutions can be harsh on the bristles and may damage them if used often or over an extended period.
  • After removing all the paint, wash your brush with warm water and mild dishwashing soap to restore the bristles to their natural condition.

To remove the paint from the brush, gently wash the bristles with a bar of mild dish soap or a soap bar and rub the soap into the brush. Oil paint may be effectively removed with dishwashing without being harsh on the bristles. To clean oil paint, lightly massage a tiny bit of dish soap into the bristles of your brushes, creating a lather.

7. Essential Linseed Oil To Clean Oil Paint Brushes

Brush bristles may eventually grow dry and brittle, particularly if they are regularly exposed to solvents. To improve brush functionality and prevent bristles from drying up, soak them from time to time in essential oils like linseed oil. In addition to linseed, sunflower, walnut, and olive oils can also be used.

  • Apply a small amount of linseed oil to the bristles, leave it to rest overnight, and then brush off any excess.
  • This will help to remove oil and soften the paint.
  • Wipe the brush on a paper towel and repeat until the paint is gone.

Despite cleaning, the linseed oil keeps the bristles from drying out and getting damaged, making them soft. Winsor & Newton Refined Safflower Oil and Winsor & Newton Refined Linseed Oil are great examples of mediums that do double duty as brush cleaners.

Steps
