Clean your paintbrush thoroughly after each use
When it comes to painting with acrylics, you don't want to slack with cleaning your paintbrushes, otherwise you may wind up with a frayed and/or crusty brush that is no longer usable for traditional art-making purposes (as you will know after reading all about proper paintbrush care!). Therefore, once you are done painting, it is in your best interest to pamper your brush with a full beauty spa treatment to get it clean, refreshed, and ready for the next painting session!
How to clean paintbrushes
When you are done painting with a particular brush, you must clean it right away to avoid acrylic paint drying on the bristles. Follow this simple procedure for how to clean paintbrushes and you'll have sparkling fresh paintbrushes for the next time you want to paint!
- At your work place, before you go to the sink, place the bristles in between a paper towel or rag and squeeze out the excess paint. Note that rags are a more eco-friendly solution than paper towels because they can be reused many more times than a paper towel.
- Swish the brush around in your cup of water to release any leftover paint.
- Gently shake off the excess water and pat against towel.
- Repeat Steps 1-3 as many times as necessary to remove the bulk of the acrylic paint. This is important for Step 6.
- Go to the sink and place a small bucket, pail or bowl under the faucet. This is an eco-friendly step to prevent the acrylic paint from running down the drain and getting into the water supply.
- Rinse your brush under a small stream of running lukewarm water. Using your fingers, gently and quickly squeeze the bristles to further dislodge any leftover paint. By working quickly and using a slow trickle of water you can avoid overfilling the bucket or bowl that you've placed in the sink.
- Using special artist soap or regular hand-washing soap, put some soap on your brush and gently wash the bristles with your fingers by working the soap through the bristles.
- Rinse off the soap.
- Check to see if there is any paint left, and if there is, repeat Steps 5 and 6. Use another bucket or bowl if your first one got too full.
- Once you are certain all the paint has been removed, shake the brush to remove the excess water.
- Place the bristles in between a paper towel or rag, and squeeze out the excess water.
- Let your paintbrush dry in a safe place, preferably lying horizontally.
If you’re wondering what to do with the buckets/bowls of dirty acrylic paint water, check out this helpful article on the Golden website that outlines a DIY solution to remove the acrylic paint solids from your rinse water. They also offer another article on waste disposal that’s worth a read.
When I was a youngster our teachers instructed us to wash our paintbrushes in the sink, which kind of reveals my age, because nowadays there is a strong awareness about the dangers of plastics (such as acrylics) in our water supply and how even the tiniest plastic particles end up in the ocean, threatening marine life and the environment. With that in mind I try to recommend eco-friendly art practices whenever I can.
Take note that at some point or other, the hairs of your paintbrush will become tinted with some of the colors that you've been using. This is normal, and does not effect the performance of the brush. As long as the water runs clear as you're rinsing your brush, it should be clean, even if the bristles are tinted with color.
Do I need special soap to clean the paint brush?
There are special soaps that are meant for cleaning artist paint brushes. These soaps are gentle and milder on the hairs of the brush than regular hand soap, because they are specially formulated to clean and condition brushes. Usually one dish or bar of paintbrush soap will last you a very long time.
If you don't have any paintbrush soap, it's okay to use regular handsoap. Just don't use dishwashing liquid, which normally has chemicals that are too strong for the delicate hairs of an artist paint brush.
Here are some brush soaps specifically made for artist paint brushes:

How should I store and/or transport my paint brushes?
If you have a permanent workspace, you can simply leave your cleaned brushes lying horizontally on your tabletop or shelf until its next use. The important thing is that you don't want the bristles to get bent or damaged in any way.
I keep a lot of my brushes in a Loew Cornell Multi Bin Holder with 50 holes for holding paintbrushes, pens, pencils, etc. I have a lot of paintbrushes (72 at last count) so sometimes I double up and put 2 or 3 of the smaller ones together in one slot. The system mainly works for me as storage and organization. Because I keep so many brushes crammed into this holder, it takes a few extra seconds to look through and find the ones I need. Therefore, before I start painting I'll select the brushes I think I'll be using for that painting session and set them aside.
Paintbrush storage and transport ideas
If you have limited space and need to tuck your paintbrushes away somewhere, you can put them inside a long rectangular box, such as a shoebox or a plastic food storage container. There are also quite a few storage solutions available from the art supply stores, such as these:
If you make a purchase via the links below I receive a small commission, which helps support this site.
This Holbein Adjustable Brush Holder is the most compact of the storage ideas, making it a good option for transport. It consists of a translucent plastic tube that can hold brushes up to 13' (22cm) long. While it is handy and compact, it doesn't have a way to prevent the brushes from banging up against the end of the tube. Therefore if you use one of these, but sure not to carry it upside-down!
An alternative to the plastic tube brush holder is this neat Bamboo Brush Roll-up that can safely store and protect up to 12 paintbrushes. You can put both wet or dry paintbrushes in this bamboo cloth holder, because it is quite airy and dries easily. To transport, simply roll it up and tie it shut.
If you need to store or transport more than a dozen paint brushes, the ArtBin Essentials Brush Box is a good choice because it keeps the paintbrushes in place so that they won't bump against the end of the box and get damaged. It can hold 20 brushes, fastened in place with foam inserts. This box features vented sides, to allow the brushes to dry.

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.
Clean Acrylic Paint Off Brushes
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.
