How to Clean Oil Paint Brushes

Introduction

Cleaning oil paint brushes properly is essential to extending their lifespan and maintaining smooth, consistent painting results. Because oil paints do not dissolve in water, the right solvents and techniques are necessary to remove residue without harming the brush fibers.

What You'll Need

• Odorless mineral spirits or paint thinner

• Paper towels or rags

• Mild dish soap

• Small cleaning jar or container

• Comb or brush-cleaning tool (optional)

Steps

Wipe off as much excess paint as possible onto a rag or paper towel.
Pour a small amount of mineral spirits into a jar and swirl the brush gently to loosen the paint.
Wipe the brush clean and repeat until the solvent comes away mostly clear.
Wash the brush with mild dish soap and warm water to remove solvent residue.
Rinse thoroughly, reshape the bristles, and let the brush dry flat.

Alternative Methods

• Use linseed oil to loosen oil paint if you prefer avoiding harsh solvents

• Use a commercial brush-cleaning soap specifically designed for oil paints

• Try a two-stage system using oil to loosen paint, then soap and water to finish

What NOT to Do

• Do not use hot water, which can loosen the brush’s glue

• Do not soak brushes in solvent for long periods, as it can damage bristles

• Do not store brushes upright while wet, as water or solvent can seep into the ferrule

FAQs

Can I clean oil paint brushes with just water?

No. Water will not break down oil paint. You must use a solvent such as mineral spirits or a specialized brush cleaner.

How often should I clean my oil paint brushes?

Brushes should be cleaned after every painting session to prevent dried paint from stiffening the bristles.

Is there a way to reduce the smell of solvents?

Yes. Choose low-odor or odorless mineral spirits, and clean your brushes in a well-ventilated area.
