Yes, linseed oil can be used to clean oil paint brushes. In fact, it is a common and effective method for removing oil paint.
Why Use Linseed Oil to Clean Brushes?
- Solvent Properties: Linseed oil acts as a solvent, helping to break down and dissolve the oil paint residue on your brushes.
- Compatibility: Since you likely already use linseed oil as a painting medium, using it as a cleaner minimizes the risk of introducing incompatible chemicals to your brushes. This helps maintain brush integrity and performance.
- Conditioning: Linseed oil can help condition the brush bristles, preventing them from drying out and becoming brittle.
- Alternative to Harsh Solvents: While solvents like turpentine or mineral spirits are effective, they can be harsh on brushes and pose health risks. Linseed oil is a gentler, more natural alternative.
How to Clean Brushes with Linseed Oil:
-
Wipe off Excess Paint: Before using linseed oil, thoroughly wipe as much excess paint as possible from the brush onto a cloth or paper towel.
-
Dip and Swirl: Dip the brush into a container of linseed oil (refined linseed oil is a good choice). Swirl the brush around in the oil, working the oil into the bristles to loosen the paint.
-
Wipe Again: Wipe the brush again on a clean cloth or paper towel, removing the paint-laden oil.
-
Repeat (if needed): Repeat steps 2 and 3 until most of the paint is removed.
-
Wash with Soap and Water: After cleaning with linseed oil, wash the brush with warm water and a mild soap (like dish soap or a specialized brush cleaner) to remove any remaining oil and paint residue.
-
Reshape and Dry: Gently reshape the brush head and allow it to dry completely. Laying the brush flat is often recommended.
Refined vs. Stand Oil
While both refined and stand oil can be used, refined linseed oil is generally preferred for cleaning due to its lower viscosity and better solvent properties compared to stand oil.
Important Considerations:
- Ventilation: Always work in a well-ventilated area, even when using natural oils like linseed oil.
- Proper Disposal: Dispose of paint-soaked rags properly to prevent spontaneous combustion. Air dry them spread out before disposal.
Using linseed oil to clean your oil paint brushes is a practical and effective method, especially if you are already using it as a medium. It helps to maintain your brushes and is a gentler alternative to harsh solvents.
