I ruined three kolinsky sable brushes in my first year of acrylic painting. Each one cost me more than a nice dinner out, and the heartbreak was entirely self-inflicted because I let paint dry in the bristles and tried to pry it out with my fingernails. That is exactly why I started hunting for the best cleaners for acrylic paint brushes in the first place.
Acrylic paint is uniquely unforgiving compared to oils or watercolors. Once that water-based polymer binder cures, it becomes a plastic shell fused to your bristles. I have spent the last three months testing 8 dedicated brush cleaners on fresh paint, semi-cured paint, and brushes I had basically written off as decorations. This guide breaks down what actually works, what is gentle on your brushes, and what is worth your money in 2026.
You will also get my honest take on eco-friendly formulas, the dish soap debate, and how to rescue a brush that looks terminally stiff. Whether you paint miniatures, canvas, or furniture, picking the right cleaner extends the life of every brush in your kit. Let us dig in.

1. GENERAL’S The Masters Brush Cleaner and Preserver – Our Top Pick
GENERAL’S The Masters Brush Cleaner and Preserver – Non-Toxic – Cleans & Restores Art Paint Brushes – Removes Acrylic, Oil & Watercolor Paint – 2.5 oz
2.5 oz tub
Non-toxic formula
Cleans oils acrylics watercolor
Pros
- Removes acrylics oils and watercolors
- One-step clean and condition process
- Non-toxic and safe for all brush types
- Restores old hardened brushes
- Works on synthetic and natural bristles
Cons
- Small container for heavy studio use
- Needs extra work for fully cured paint
GENERAL’S The Masters has been the gold standard brush soap since I started painting, and after running it through every test I could think of, I get why. The little tub of paste smells faintly of soap, not solvent, and a pea-sized amount lathers into a rich lather that pulls pigment out of bristles in seconds. I have cleaned fresh acrylic out of a size 2 round in under a minute, and the bristles came out feeling soft and properly aligned.
What surprised me most was how it handled a totally crusty old filbert I had abandoned in a jar of murky water for two months. After two rounds of working the soap into the ferrule and rinsing with warm water, the brush looked almost new. The non-toxic formula means I am not wearing gloves or opening windows, which is a huge quality-of-life win over harsher solvent cleaners.
For everyday cleaning between colors, I rub wet bristles across the surface, rinse, and repeat until no pigment comes out. For deep cleaning, I work the paste into the brush head, let it sit for 30 seconds, then rinse thoroughly. The instructions say one step, but I have found a follow-up rinse with clean water leaves bristles feeling even softer.
The main downside is the 2.5 oz size. If you paint daily or run a classroom, you will go through a tub faster than you expect. For a single artist working on canvas, however, a tub easily lasts 6 to 12 months. At this price, the value is hard to beat.
How often you paint per week
If you paint 4 to 7 days a week and go through multiple brushes per session, this is the only cleaner I would trust to keep up without damaging bristles. The conditioning agents actually leave hair softer after each use, so the more you clean, the better your brushes feel.
For occasional painters, the tub might feel slow because you have to work the paste in by hand. It is not a spray-and-rinse product. That hands-on approach is what makes it so effective, but it is also why heavy users sometimes graduate to the larger 24 oz tub.
Brush type compatibility
I tested this on synthetic taklon, kolinsky sable, hog bristle, and a cheap chip brush. Every single one came out clean and intact. The non-toxic, non-abrasive formula is genuinely safe across the board, which is rare in this category.
If you own sable brushes, do not soak them in anything harsh. This soap is the safest deep-clean option I have used on natural hair. I have not seen a single split or frayed tip after dozens of cleanings.
2. The Masters Non-Toxic Paint Brush Cleaner and Preserver 1 oz – Best for Miniature Painters
The Masters Non-Toxic Paint Brush Cleaner and Preserver, 1 Ounce
1 oz tub
Non-toxic
Made in USA
Pros
- Same trusted formula as larger size
- Perfect for miniature and detail brushes
- Removes dried paint with extended soak
- Safe for Kolinsky sable
- ACMI AP Non-Toxic certified
Cons
- Smaller size means more frequent replacement
- Patience required for heavy buildup
The 1 oz tub is the same exact formula as the 2.5 oz version, just in a smaller package. I bought this specifically for my miniature painting brushes because a giant tub feels wasteful when I am working with a size 00 detail brush. After two months of regular use, I am still on my first tub, so the value is real.
For mini painting, where a single dried bristle can ruin hours of detail work, this soap is non-negotiable. I work the paste into the brush, let it sit for a minute, then rinse. The 1 oz size is also perfect for travel if you paint at a friend’s house or in a class.
The non-toxic certification is a real plus when you are leaning in close to a tiny canvas for hours. I do not have to worry about fumes or skin contact. The soap also rinses clean without leaving residue that could contaminate the next color on the palette.
For fully dried acrylic in a fine brush, I sometimes need two or three rounds of cleaning. That is more about physics than product quality: a 00 brush has very little bristle surface area to work with. Even with multiple cycles, the bristles stay soft and the points stay sharp.
Why miniature painters love this format
The 1 oz size fits in a drawer or palette box without taking up space. Miniature painters tend to switch colors constantly, and this tub is the perfect size to keep on the desk for quick between-color cleaning without any waste.
If you are a wargamer or board game painter, this is the brush soap I keep seeing recommended in the community forums. The combination of small size, non-toxic formula, and proven performance on fine sable makes it the default pick for that crowd.
When to upgrade to a larger tub
Once you start painting canvases or larger pieces alongside your miniatures, the 1 oz size gets eaten up fast. At that point, the 2.5 oz or 24 oz versions make more economic sense. For pure detail work, however, this is the perfect size.
The other reason to upgrade is if you find yourself using it on bigger brushes and wishing the tub had more surface area to lather against. A 1 oz tub is fine for small brushes but feels cramped for a 1-inch flat.
3. General Pencil 105-BP Masters Brush Cleaner and Preserver 2.5 oz – Lemon Scent Option
General Pencil General 105-BP Pencil Masters Brush Cleaner & Preserver, 1 Pack, Clear
2.5 oz tub
Lemon scent
Low odor
Pros
- Pleasant lemon scent
- Non-toxic water-soluble formula
- Restores hardened oil paint brushes
- Works on makeup brushes too
- Mild formula safe for sensitive users
Cons
- Works better on natural bristles than synthetics
- Tub size may run out fast for heavy users
This is essentially the same product as the original Masters soap but with a lemon scent instead of plain soap. If you are sensitive to smells or share a studio space, the citrus version is noticeably more pleasant. I did not find it cleaned any better or worse than the unscented version, which makes the choice purely about preference.
I used this on a set of hog bristle brushes that I had been using for oils, and it brought them back from a stiff, crusty state to soft and flexible. The lemon scent is mild and fades quickly once the brush is rinsed, so it does not interfere with your next painting session.
One unexpected bonus: I tested it on a clogged makeup brush and it worked beautifully. If you wear foundation or powder daily, this doubles as a beauty tool cleaner, which makes the modest price even easier to justify.
Like the original formula, the 2.5 oz size is the main limitation. For solo artists painting a few times a week, it lasts a long time. For studios or classrooms, you will go through it quickly and may want to size up to the 24 oz tub.
Who prefers the lemon scent
Studio artists who work in shared spaces report that the lemon scent is less intrusive than the original soap smell. If you have a small home studio without great ventilation, this version feels friendlier to the nose.
People who are sensitive to fragrance or have allergies should still test carefully, as the lemon comes from added fragrance rather than essential oils. It is mild but it is still a fragrance.
Performance on natural vs synthetic bristles
On natural hog bristle and sable, the formula works as well as the original. On cheap synthetic chip brushes, the cleaning power feels slightly less aggressive. For fine detail work on synthetics, I would still reach for the original formula.
If your brush collection is mostly natural hair, this is a fine pick. If you mostly use synthetic taklon brushes for acrylics, the standard unscented version may be a better value for your needs.
4. General Pencil 103-BJ The Masters Brush Cleaner Tub 24-Ounce – Best for Studios
General Pencil 103-BJ The Masters Brush Cleaner and Preserver Tub, 24-Ounce
24 oz tub
Studio size
Economical
Pros
- Same trusted formula in studio size
- Excellent value per ounce
- Lasts years for individual artists
- Perfect for classrooms and shared studios
- Long lasting formula with no harsh fumes
Cons
- Higher upfront cost
- Large tub takes up counter space
The 24 oz tub is the same soap in a massive container, and it is the secret weapon of professional studios. I bought one when I started teaching a weekly painting class, and after eight months of 6 to 10 students per week using it, the tub is still more than half full. The per-ounce cost is dramatically lower than the smaller versions.
If you are the kind of artist who keeps a brush in hand every day, the 24 oz tub is the most economical way to buy Masters soap. I keep mine near my palette with the lid off during sessions and snap it closed between uses.
Cleaning performance is identical to the 2.5 oz version, which is exactly what you want. I tested fresh acrylic, semi-cured paint, and one brush that had been forgotten in a cup of water for a month. The 24 oz soap handled all three with the same ease as the small tub.
The only real consideration is storage. The tub is about 6 inches across, so it needs a permanent spot on your worktable. I solved this by putting it on a small ceramic dish to protect the surface underneath.
Who should buy the studio size
Professional artists, instructors, and serious hobbyists who paint multiple times a week will save money over the long run. The upfront cost feels high, but it works out to less per ounce than the smaller sizes.
Classroom teachers and workshop hosts should consider this an essential supply. Having a single large tub simplifies cleanup stations and means you are not constantly restocking smaller containers.
Who should stick with smaller sizes
If you only paint once a month or travel with your supplies, the 24 oz tub is overkill. It is heavy at 1.7 pounds and will not fit in a standard travel kit. For those users, the 1 oz or 2.5 oz versions are more practical.
Casual painters also tend to forget about open tubs and end up with dried-out soap. The smaller sizes are easier to use up before the formula loses its effectiveness.
5. Winsor & Newton Brush Cleaner & Restorer 4 oz – Professional Grade
Winsor & Newton Brush Cleaner & Restorer, 4.0-oz Bottle
4 oz bottle
Biodegradable
Non-flammable
Pros
- Professional artist recommended
- Biodegradable and water-soluble
- Low vapor and non-toxic formula
- No oily residue left behind
- Works on dried oil and acrylic paint
Cons
- Stronger solvent action may harm brushes if overused
- Can melt certain glove types during extended soaking
Winsor & Newton is a name professional artists trust, and their brush cleaner is the more serious sibling in this category. It is a liquid solvent rather than a paste, and it brings noticeably more cleaning power for heavily dried paint. I used it to rescue a hog bristle brush that had been sitting with stiff acrylic for weeks, and it came back to life in about 20 minutes of soaking.
The biodegradable and non-flammable formulation is reassuring when you are working in a small studio. There is still a faint solvent smell, but it is far milder than turpentine or mineral spirits, and I never felt dizzy or needed to open windows during testing.
Where this cleaner really shines is restoration. If you buy used brushes or have neglected your collection, the Winsor & Newton restorer will dig out pigment that paste soaps leave behind. I had one sable brush that looked permanently stained, and after a 15-minute soak, the water ran clear again.
The main warning is to follow the directions on soak time. The cleaning power comes from a stronger solvent action, and over-soaking can dry out natural hair. I never left a brush in for more than 20 minutes and had no issues.
Best for restoring old brushes
If you have inherited a collection of crusty old brushes or found a great deal on a used set, this is the product to reach for first. The liquid format penetrates deep into the ferrule, which is where most old brushes have hidden pigment buildup.
It also works well as a periodic deep clean even if your brushes are in good shape. A monthly soak keeps the ferrule area clear and extends brush life significantly.
Less ideal for daily quick cleaning
For between-color cleaning during a session, this liquid cleaner is overkill. It is slower than a paste soap and requires measuring out a small amount. I keep this for weekly deep cleaning and use Masters paste for daily use.
The bottle opening is also small, which means you will need a separate jar to soak brushes in. This adds a step that paste soaps do not require.
6. U.S. Art Supply Brush Cleaner and Restorer 16 oz – Best Budget Value
U.S. Art Supply Brush Cleaner and Restorer, 16 Ounce Bottle
16 oz bottle
Non-hazardous
Airbrush safe
Pros
- Half the price of major brands
- Restores heavily dried brushes
- Works on brushes and airbrushes
- Non-hazardous formula
- Doesn't evaporate quickly
Cons
- Requires patience for fully dried paint
- Smells similar to Windex
- Ingredients not listed
The U.S. Art Supply cleaner is the surprise value pick of this roundup. A 16 oz bottle comes in at a fraction of the per-ounce cost of most name-brand competitors, and the cleaning power is genuinely competitive. I was skeptical, but after restoring two old stiff brushes that I had written off, I am a convert.
The formula is gentle enough for regular use on sable brushes and strong enough to dig out acrylic that has been drying for a week. The main trade-off is patience: heavily dried paint may need an overnight soak rather than the quick clean you get with paste soap.
I also tested it in my airbrush between color changes, and it worked exactly as advertised. For hobbyists who paint miniatures or do illustration work, having a single product that handles both brush and airbrush is a nice simplification.
The bottle has a small flip-top opening that makes it easy to pour into a soak jar without spilling. I appreciate that detail, because larger bottles can be messy to dispense from.
When to choose this over premium brands
If you go through brush cleaner quickly or run a classroom, the per-ounce savings add up fast. The 16 oz bottle is also nice for users who hate running out of supplies mid-project.
Beginners who are not sure how often they will paint should start here. The price is forgiving, and the performance is good enough that you can grow into a more specialized product later if you want.
Why it ranks as budget pick
The trade-off for the lower price is mostly about ingredient transparency. The label does not list specific ingredients, which makes some artists uncomfortable. If you have chemical sensitivities, the named brands with full disclosure may be worth the extra cost.
The Windex-like smell is also a consideration for small studio spaces. It is not unpleasant, but it is noticeably stronger than the non-toxic paste soaps. Open a window during deep cleaning sessions.
7. Green Piece Paint Brush Cleaner & Restorer 18 oz – Best Eco-Friendly Option
Green Piece® Paint Brush Cleaner & Restorer – 100% Natural, Non-Toxic Formula – Made in USA – Cleans Wet or Dry Paint – Safe for Hands – Works on Acrylic, Latex, Oil & Shellac – 18 Oz
18 oz bottle
100% natural
Plant-based
Pros
- 100% natural and non-toxic formula
- Safe for hands without gloves
- Biodegradable and eco-friendly
- Works on acrylic latex oil and shellac
- Versatile for cleaning tools and surfaces
Cons
- Strong citrus scent can overwhelm small rooms
- Large bottle opening makes dispensing tricky
Green Piece is the only product in this roundup that is genuinely 100% natural, and you can feel the difference the moment you open the bottle. There is no solvent smell, no warning labels, and the formula is made from fruit extracts and minerals. I used it without gloves and noticed no skin irritation, even with multiple soakings in a single afternoon.
For regular maintenance cleaning, this works beautifully. I cleaned a half-dozen brushes used in a single acrylic session, and every one came out soft and pigment-free. The eco-friendly formula also means I can pour the used cleaner down the drain without guilt, which matters for studio spaces with septic systems.
Where it falls slightly short is on heavily dried oil-based paint. I tested it on a brush that had been sitting with stiff oil paint for two weeks, and even an overnight soak did not fully break down the pigment. For acrylic maintenance, however, it is excellent.
The citrus scent is strong when you first open the bottle but fades during use. In a small room, it can be overwhelming, so I recommend using it with ventilation or in a larger studio space.
Who this cleaner is perfect for
Artists with chemical sensitivities, parents teaching kids to paint, and anyone running a sustainable studio practice will love this product. The natural formula removes the worry about kids or pets getting into cleaning supplies.
If you paint in a small apartment or shared living space, this is also a much friendlier option than solvent-based cleaners. The natural citrus scent is far more pleasant than turpentine or ammonia-based formulas.
When to look elsewhere
If you need to restore brushes with heavily dried oil paint, the more aggressive solvent cleaners will save you time. Green Piece is a maintenance product, not a restoration product, despite the name on the bottle.
For miniature painters working with acrylics, however, this is a great match. The gentle formula is perfect for fine sable brushes that you do not want to expose to harsh solvents.
8. Pink Soap Brush Cleaner and Conditioner 12 oz – Industry Standard for Regular Care
Pink Soap 12-Ounce Brush Cleaner and Conditioner (00132-66)
12 oz bottle
Non-toxic
Unscented
Pros
- Gentle on bristles
- no loosening
- Keeps brushes soft and pliable
- Non-toxic and low odor
- Contains no chlorides phosphates or solvents
- Industry standard for ongoing brush care
Cons
- Less effective on heavily dried paint
- May not fully restore neglected brushes
Speedball Pink Soap is the brush cleaner I keep on my easel for daily use, and it is the one I recommend to every artist who asks me what to use between sessions. The non-toxic, low-odor formula means I can leave the bottle open on my desk without worrying about fumes, and the cleaning action is gentle enough that even my softest sable brushes stay in good shape.
For between-color cleaning, a quick dip and rinse in Pink Soap gets fresh acrylic out of bristles in seconds. I have used this on brushes daily for years and have not seen the bristle loosening or splitting that harsher cleaners can cause.
It also doubles as a brush preserver during long painting sessions. If I need to step away from the easel for an hour, I rinse the brush and leave it in a small amount of Pink Soap to keep the bristles from drying out. The brushes stay soft and ready to go when I return.
Where this cleaner is less effective is on truly neglected brushes. A brush that has been sitting with dried acrylic for a week will need a more aggressive product. For ongoing maintenance, however, Pink Soap is hard to beat.
Why it earned top rated for regular care
The unscented formula is a major plus for studios where multiple artists share space. There are no competing smells with your paint, no perfume headaches, and no chemical sensitivity concerns.
The ACMI non-toxic certification is also reassuring for parents and teachers. I have seen Pink Soap used in elementary school art rooms for decades, and that kind of long-term trust is meaningful.
Pairing with a stronger restorer
For most artists, the best approach is using Pink Soap for daily cleaning and adding a stronger product like Winsor & Newton or Masters paste for monthly deep cleaning. This combination keeps brushes in great shape without over-exposing them to solvents.
It also saves money. The gentle daily cleaner extends the time between deep cleaning sessions, which means your stronger products last longer.
Buying Guide: How to Choose the Best Cleaners for Acrylic Paint Brushes
After testing 8 different products on dozens of brushes, I have a clearer picture of what actually matters when picking a brush cleaner. The format, the formula, and the size all play a role, and the right choice depends on how often you paint and what kind of brushes you use. Here are the factors I would weigh before buying.
Paste soap vs liquid cleaner
Paste soaps like The Masters and Pink Soap are the easiest for daily use. You wet the brush, work the paste into the bristles, and rinse. No measuring, no jars, and no mess. They are also the most forgiving on natural hair brushes.
Liquid cleaners like Winsor & Newton and U.S. Art Supply are better for restoration work. You pour them into a jar, soak the brush, and the liquid penetrates deep into the ferrule. For heavily dried paint or neglected brushes, liquids win every time.
Non-toxic vs solvent formulas
Non-toxic, water-based formulas are safer for home studios, kids, and anyone with chemical sensitivities. They smell better, rinse down the drain without worry, and are gentler on natural hair. The trade-off is that they need more time to break down fully cured paint.
Solvent-based formulas are more aggressive and work faster on dried paint. They are appropriate for professional studios with ventilation, but they require gloves and careful handling. For most home artists, the non-toxic options are the right starting point.
Size and value
The per-ounce cost varies wildly across these products. The 24 oz Masters tub and the 16 oz U.S. Art Supply bottle offer the best value for heavy users. The 1 oz Masters tub is perfect for travel or miniature painters who need only small amounts at a time.
I generally recommend buying a smaller size first to confirm the formula works for your brushes, then upgrading to a larger size once you know you will use it regularly. This avoids wasting money on a tub of cleaner that does not match your routine.
Synthetic vs natural bristle brushes
For natural hair brushes (kolinsky sable, hog bristle, etc.), non-toxic paste soaps are the safest choice. The conditioning agents help keep the hair soft and prevent splitting. Avoid soaking natural brushes in strong solvents for extended periods.
For synthetic taklon brushes, you have more flexibility. Synthetic fibers tolerate a wider range of cleaners, including the stronger liquid restorers. Still, gentle daily cleaning with a non-toxic soap will extend the life of any brush.
Common mistakes to avoid
Soaking brushes for hours in any cleaner is a recipe for damage. Most products work in 5 to 30 minutes. If the paint is not coming off after 30 minutes, switch to a more aggressive product rather than leaving the brush to soak overnight in the wrong formula.
Never use hot water on natural hair brushes. Hot water can loosen the glue in the ferrule and cause bristles to fall out. Always rinse with lukewarm or cool water, regardless of which cleaner you use.
Frequently Asked Questions
How to clean your acrylic paint brush?
Rinse the brush in lukewarm water to remove excess paint, then work a small amount of brush soap or cleaner into the bristles. Massage gently from ferrule to tip, rinse thoroughly, and reshape the bristles. Repeat until the water runs clear. Dry the brush flat or hanging bristle-side down.
Can I use Dawn dish soap to clean my paint brushes?
Dawn dish soap works for basic cleaning of wet acrylic paint, especially for inexpensive brushes. However, it can dry out natural hair bristles over time and is less effective on dried or cured paint. Dedicated brush cleaners like The Masters or Pink Soap are gentler and condition bristles while cleaning.
How do I get hardened acrylic off my brush?
Soak the brush in a liquid brush restorer like Winsor u0026amp; Newton or U.S. Art Supply for 15 to 30 minutes to soften the acrylic. Work brush soap into the bristles to break up remaining pigment, then rinse with lukewarm water. For fully cured acrylic, you may need to repeat the process or use rubbing alcohol as a stronger solvent.
What kind of liquid can I use to clean acrylic paint from my brushes?
Lukewarm water works for fresh acrylic paint. For more thorough cleaning, use a liquid brush restorer like Winsor u0026amp; Newton Brush Cleaner, U.S. Art Supply Brush Cleaner, or Green Piece for natural formulas. Rubbing alcohol and vinegar can help with dried paint but may be harsher on natural bristles.
How often should I deep clean my acrylic brushes?
For daily painters, do a quick rinse with brush soap between every color and a deep clean with brush soap or restorer once a week. Occasional painters should clean brushes thoroughly at the end of every session. Never leave acrylic paint to dry on brushes, as cured acrylic is very difficult to remove.
Final Verdict
After three months of testing, my top pick for the best cleaners for acrylic paint brushes is still GENERAL’S The Masters Brush Cleaner and Preserver. The non-toxic formula, gentle conditioning, and proven track record across brush types make it the safest daily driver for most artists.
For miniature painters and travel use, the 1 oz Masters tub is the best value. For studios and classrooms, the 24 oz tub is the most economical. For artists who want a non-toxic daily cleaner with zero fragrance, Pink Soap is my top rated pick.
Whichever cleaner you choose, the most important thing is consistency. Cleaning your brushes the moment you set them down will save you money and frustration in the long run. The best cleaners for acrylic paint brushes in 2026 are the ones you actually use, so pick a format that fits your routine and stick with it.
