Turpentine or paint thinner helps soften paintbrushes affected by oil-based paint or stain. Either one of these solvents also works for hardening problems caused by varnish or enamel paint. After soaking the stiff brush for at least half an hour in a well-ventilated area, rinse the brush under hot water, then wash the bristles in warm, soapy water. Mix fabric softener and warm water in a bucket. Begin swirling your paint brush in the mixture until paint starts to come off and sink to the bottom of the bucket. Once clean, rinse off any remaining solution in the sink. Wipe on a paper towel when finished.

Haven't any of you had any professional training at all?

I don't want to steal your thunder Kelly, but this is not Best Practice.

Don't ever put paint thinner into plastic. It will melt most kinds. Why risk a mistake? Old glass salsa jars exist for brush cleaning. label one, put some glass marbles like the flower arranging ones into the bottom to work the brush against. (Plain, not coated with shiny stuff. It'll dissolve) Trying to clean oil based paints out of brushes by just stirring them around doesn't work. If you're desperate a crumpled piece of window screen will work too but it's hard on bristles so this is not a default. Paint thinner is very flammable and an ugly toxin so you want to keep it stingy and the stuff needs to go to Hazardous Waste Disposal. Wipe those brushes really well!

If you're doing fine arts painting go buy a proper brush cleaning pot. A big size one would be good for pro house painters. Solvent sits in it for weeks and it has a sieve to work the bristles over. Paint solids drop below it. The top keeps fumes in and evaporation almost nill over weeks. Minimal exposure, clean brushes. Now wash them! I wash up to thirty brushes a day in the studio; it's just doing the dishes.

Do NOT use a surfactant/ detergent 'soap'. Use a real soap, a chemically designated soap, with oil or fat in it. You can put it on a cellulose sponge and work the brushes across it to work up a lather, or just work them against your palm. If you use bar soap swipe the brushes across it. The soap cuts the oil, and the fat base conditions the bristles.If you wiped out the paint and rinsed in thinner properly there's very little to wash out. More like a post gym shower then wrestling gunk. You don't want paint in a sink drain or on the back patio. Rinse well. If you do this correctly you'll get to wear brushes out instead of throwing them away. And bristles are chosen for this exposure so they'll get better. It's just like washing your hair. Squeeze out the water and shape them, air dry.

This works for synthetic brushes too. Do not leave soap in the bristles as it will contaminate your paint next time and make a bad paint film. As for exotic paints like epoxy? Yes, use nitrile gloves and a respirator! Outside. But if the stuff is hydrocarbon based a fat soap should work too. Acetone on brushes will kill them fast, so make sure thats a really Best Practice. Again- a soap may work better. Most bristles need the conditioning.

If your brushes start to get that gunky icky feeling, soaking them in that inexpensive liquid oil soap from the grocery store (Also best for regular washing after painting) is like a spa treatment. Leave them in for two or three days. It's magic! Paint in the ferules is a ruined brush, but as regular maintenance this is amazing. I have ten year old mongoose thats still sweet. I also paint a lot.

Do not use soap on watercolor brushes. Just rinse.

This is the method professional painters use; It keeps solvent use to an absolute minimum. Reusing a cup or 12 ounces of thinner instead of blowing through gallons of it reduces exposure and that stuff has lead in it. Among other scary things. Don't use it on skin either. Paint'll fall of in 48 hours if soap or olive oil doesn't get rid of it.

Even if you use a thinner only system like the guys who paint cars using industrial paints, a cleaning pot will use less thinner and reduce your chemical exposure. They can be used in series. You can eyeball them at the big online art supply stores, and I shop at industrial supply so don't think they don't interchange. ;-D I'll try to post instructions for the homemade version.

You pull a clean, fresh paintbrush out of the pile, and a smile stretches instantly across your face. There is simply no better feeling!

Wouldn’t it be amazing if you could keep your brushes in this good of shape for as long as possible? It may not come as a surprise, but all it takes is some regular care and maintenance.

But, while dirty brushes are the bane of every painter’s existence, they happen. Whether they are accidentally forgotten about after a long day in the studio or merely on their last leg, seasoned artists and brush makers have a few tricks up their sleeves for bringing your brushes back to life.

So, think twice before you pop that trashcan lid, and consider these twelve tips for caring for and salvaging your favorite brushes.

“Repeat the washing and rinsing process until the soap and water runs clear. Keep your water warm, but not hot, as hot water may cause any remaining paint to clot.” - Winsor & Newton

“Soaking your brushes in fabric softener periodically will help restore softness and pliability to their bristles, keeping them from becoming brittle and breaking off.” - Paint Nite

“You can use vegetable oil for cleaning a palette and dish soap and water for brushes. Just don’t let them sit in the water—it will ruin them. But, if they do lose shape, you can stick them in boiling water for a few seconds and they will reshape.” - Lori McNee, Fine Art Tips

“ Remove all excess paint with a soft rag or paper towel. Never let your brush rest on its head. There are many accessories available that will suspend your brush.” - Princeton Artist Brush Co.

“The most important thing to remember with regard to caring for your acrylic brushes is not to let the paint dry following use, as the paint is not soluble in this state and will produce a plastic-like dried texture.” - Winsor & Newton

“Soak oil paint-covered brushes for 5-10 minutes in baby oil (yes, baby oil). This gets a lot of paint and medium off before washing thoroughly with mild soap and warm water. “ - Teri Granger Martin

Cleaning Hardened Paint Brushes

“The area near the ferrule is often the hardest to clean, but it's actually just as important for maintaining a brush's shape as the tip. Any paint residue that coats the bristles at their base will prevent them from coming together at the top.” - Craftsy

“If the ferrell gets gummed up, I was told that you can soak your brushes in rubbing alcohol for a couple of days and that will solve the problem.” - Carol McIntyre

“After washing with dish soap and water I finish the job as a usual rule with olive oil! You fight oil base with oil! Won't believe how much oil paint is removed from what I thought was a clean brush! The olive oil keeps the bristles soft as well!”

“Grab a glass cup and fill it about 1-2 inches deep with distilled white vinegar. Heat it in the microwave for 1-1.5 minutes then submerge your nasty paintbrushes into it… Take some dish soap (Dawn, Palmolive, etc.) and rinse off the brushes in warm soapy water.” - Crafty Morning

“If you have a painting project in mind, but the only paintbrushes you have are old, hard, and frayed, don’t go through the trouble of buying new ones. Revive old acrylic brushes with hair gel instead! Coat frayed bristles with any hair gel to mend the tips, then wash and soak them in fabric softener. They’ll be good as new!” - Paint Nite

“No matter what works for you, ensure that you reshape your brushes to the way they first looked when you bought them before you let them dry.” - Rosemary and Co
