The Masters Brush Cleaner is the best cleaner for oil paint brushes for most artists.

You finish a long session at the easel and your favorite filbert is stiff with Alizarin. I’ve been there.

In this guide, I compare the best cleaner for oil paint brushes from trusted brands. I’ll show what actually works on tacky, half-cured paint, what’s safe for your hands, and what revives a “doomed” brush. I’ll keep it simple and honest, so you can clean faster and paint more.

The Masters Brush Cleaner & Preserver, 2.5 oz

Check the price on Amazon

If you ask any working painter about the best cleaner for oil paint brushes, The Masters will come up fast. This palm-sized soap cuts through linseed oil, stand oil, and stubborn pigments without wrecking bristles. It’s non-toxic and has a gentle lather that reaches into the heel near the ferrule. I’ve restored splayed hog bristles and gummy sables with it after sessions that went way too late.

The real magic is in the “preserver” part. Once the paint is out, I work up a light lather and shape the tip. The brush dries with a crisp edge and nice spring. It also removes dried acrylic and watercolor, so it plays well with mixed-media kits. It’s long-lasting, travels well, and smells clean, not chemical.

Pros:

• Non-toxic formula safe for studio sinks and hands
• Restores shape and snap while cleaning oil and acrylic
• Great for deep-cleaning at the ferrule where paint hides
• Compact tub lasts a long time and is travel-friendly
• Conditions natural and synthetic bristles

Cons:

• Small size; frequent users may want a larger tub
• Not a fast dip cleaner for wet-in-wet sessions
• Very heavy, baked-on oil may need a pre-soak first

My Recommendation

This is the set-and-forget choice if you want the best cleaner for oil paint brushes that also preserves them. It’s ideal for artists who want safe, daily cleaning to extend brush life. If you work with natural hog or sable and care about tip shape, this deserves a permanent spot by your sink.

It’s also a smart second step after a quick solvent rinse. Use it at the end of your session for a clean brush with crisp edges. For the price and mileage, the value is excellent and stock is usually solid year-round.

Best for	Why
Daily, non-toxic brush care	Gentle soap cleans oils and conditions fiber
Restoring shape and spring	Preserver lather sets a sharp tip as it dries
Mixed-media studios	Removes oil, acrylic, and watercolor residues

Green Piece is a plant-based liquid cleaner that cuts through fresh and dried paint, including oil, latex, and shellac.

The 4 oz bottle is the same fast-acting cleaner in a travel size. I toss this into my plein air kit and use only a capful per session.

5 Best Solvent for Oil Painting: The Clear Winner You Should Be Using

FAQs Of best cleaner for oil paint brushes

What is the best way to clean oil paint brushes daily?

Wipe excess paint. Swish in a mild solvent or natural cleaner. Wash with a brush soap. Rinse, shape the tip, and let it dry flat or bristles down. This protects the ferrule and keeps spring.

Can I use mineral spirits instead of a brush cleaner?

Yes, for the first rinse. But finish with a dedicated brush soap. It removes residue, conditions bristles, and prevents long-term dryness or frizz.

How do I save a brush with dried oil paint?

Soak the bristles in a restorer. Massage the heel near the ferrule. Repeat until softened, then wash with a conditioning soap. Be patient and avoid bending the tip hard.

Are non-toxic cleaners strong enough for oil paints?

Many are. Products like The Masters and Green Piece lift oil binders well. They may take longer than harsh solvents, but they protect your health and the brush fibers.

How often should I condition my brushes?

After each deep clean. A light lather of brush soap acts as a conditioner. Shape the tip and let it dry. This keeps the edge sharp and smooth.

Final Verdict: Which Should You Buy?

The Masters Brush Cleaner is my top pick as the best cleaner for oil paint brushes for most studios. It cleans, conditions, and preserves shape with low odor.

For a greener soak that handles dried paint, choose Green Piece. If you need fast action, U.S. Art Supply’s cleaner shines. Restoring a lot of tools on a budget? Krud Kutter wins on volume and power.
