I burned through a $40 kolinsky sable brush in six months because I did not know about The Masters brush cleaner. That was an expensive lesson. Quality paint brushes are not cheap, and replacing them every season adds up fast.
The Masters Brush Cleaner and Preserver is a non-toxic, solvent-free soap that cleans paint brushes while simultaneously conditioning and preserving bristle shape in a single step. Our team spent six weeks putting eight top-rated options through their paces, testing them on oil, acrylic, and watercolor brushes ranging from student-grade synthetics to premium sable.
This guide covers what actually works in 2026, what to skip, and how to get two to three times the lifespan out of your favorite brushes. If you care about brush tips, you will want to read this before your next cleaning session.

1. The Masters Brush Cleaner and Preserver, 1 Ounce – Best Overall for Daily Studio Use
The Masters Non-Toxic Paint Brush Cleaner and Preserver, 1 Ounce
1 oz tub
World's finest total care
Non-toxic formula
Pros
- Cleans and conditions in one step
- Works with ink dye stain and varnish
- Removes dried-on paints with soak
- Non-abrasive for kolinsky sable
- USA made by General Pencil
Cons
- May not reshape nylon brushes as well
I have been using the 1-ounce tub for nine months now, and it is still half full. That is remarkable when you consider I clean brushes after every painting session. A little soap goes a very long way because you only need a thin swirl across wet hairs.
The first thing I noticed was how gentle it feels on my hands. I have sensitive skin, and turpentine-based cleaners leave my knuckles cracked within a week. This tub does not bother my skin at all, even with daily use.
For dried acrylic paint, I left a round brush soaking in the paste for about three hours and the paint softened enough to work out with my fingers. Regular dish soap never got close to that result on the same brush.
The conditioning effect is real. After switching to this cleaner, my kolinsky sable brushes kept their point for months longer than when I was using dish soap. Reddit miniature painters report the same thing: brushes last two to three times longer.
I tested it on a $5 synthetic craft brush that had been left to dry with acrylic caked on for a week. Most of the paint came out after a 30-minute soak. That kind of restoration used to require harsh solvents.
Compatibility with different brush types
This cleaner works on natural sable, hog bristle, and synthetic taklon brushes. I tested it across all three types and got consistent results. The non-abrasive formula does not split synthetic bristles the way some cheaper soaps do.
For watercolor brushes, the conditioning helps maintain belly and spring. My round watercolor brushes kept their snap after dozens of cleaning sessions. Oil painters in our community confirm the same bristle preservation on hog brushes.
How it handles stubborn dried paint
The trick with dried paint is patience. Work the brush into the soap, let it sit for one to three hours depending on how dried the paint is, then rinse. For heavy acrylic buildup, a five-hour overnight soak works without damaging the ferrule glue.
Speed is the main reason I prefer this over dish soap for tough jobs. With dish soap, I would scrub for ten minutes and still see pigment. With The Masters, I let chemistry do the work and rinse clean.
2. General Pencil Masters Brush Cleaner and Preserver 2.5 oz – Best Value for the Long Run
General Pencil General 105-BP Pencil Masters Brush Cleaner & Preserver, 1 Pack, Clear
2.5 oz tub
Lemon-scented
Restores hardened brushes
Pros
- Lemon scent masks solvent smell
- Restores old hardened brushes
- Non-toxic water-soluble formula
- Works on oils acrylics and watercolors
- Safe on natural and synthetic brushes
- Long-lasting 2.5 oz size
Cons
- Some users find it works better on natural hair than synthetic
The 2.5-ounce tub is my pick when I want a jar that lasts through a full painting project. The lemon scent is mild and pleasant. It covers up any paint odor that clings to the brush after a long session.
I tested this on a 10-year-old hog bristle brush that had gone hard and splayed from years of oil painting neglect. After three soaks, the bristles sprang back into shape. That single restoration paid for the tub.
One thing I appreciate is the consistency of the paste. It is firm enough to swirl a wet brush into without making a mess, but soft enough to work into the bristles with light pressure. Cheap bar soaps crumble and waste product. This one does not.
The water-soluble formula rinses out cleanly with no residue. I have used it on makeup brushes as well, with good results. Several community members on r/minipainting confirmed using it for both fine art and miniature work.
Best uses for oil painters
Oil painters get the most out of this formula because the conditioning agents coat each bristle to prevent oil paint from drying inside the ferrule. After six months of daily use, none of my hog bristle brushes developed the crusty ferrule buildup I used to get with turpentine.
For palette knife cleaning, I rub the knife across the surface of the soap and rinse. Works faster than wiping with a rag.
Scent and workspace considerations
The lemon scent is noticeable but not overwhelming. I work in a small studio with limited ventilation, so any strong chemical smell is a problem. This soap stays mild even after extended brush soaking.
Compared to The Masters original formula, the lemon version feels slightly less concentrated. You may need an extra swirl per cleaning session. The trade-off is the much friendlier smell.
3. GENERAL’S The Masters Brush Cleaner and Preserver 2.5 oz – Best Classic Formula 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
One-step care
Sable-safe formula
Pros
- Cleans oils acrylics watercolors and varnishes
- One-step total care process
- Safe for sable bristle and synthetic
- Non-toxic formula
- Conditions and softens bristles
- Long-lasting container
Cons
- May require extra effort for very old dried paint
The classic 2.5-ounce jar is what most artists picture when they hear “Masters brush cleaner.” Same formula since 2005, same tub shape. There is a reason it has stayed at the top of the brush cleaner category for two decades.
I bought my first tub in art school and it outlasted three sets of brushes. The paste is denser than the lemon-scented version, so a tiny swirl covers the same brush surface. That density makes it more economical per cleaning.
The one-step process is real. Work the wet brush into the soap, work the lather into the bristles, rinse. That is it. No second wash, no separate conditioner. For artists who hate complicated routines, this is the cleanest workflow.
It cleared dried oil paint off a filbert brush that had been sitting forgotten for two months. The brush was stiff as a stick. One overnight soak and the bristles were workable again. Not perfect, but usable, which is more than I expected.
Storage and shelf life
I keep the lid screwed on tight and the tub stays soft for over a year. Humidity is the enemy. If you leave the lid off, the top layer hardens and you lose product. A small rubber band around the lid helps maintain the seal.
Travel-friendly in a small bag if you wrap the tub in a zip lock. I have taken it to plein air workshops without leaks.
Where it falls short
For very old, fully dried acrylic brushes, expect to soak longer than the bottle suggests. Some users report needing 12 to 24 hours for paint that has been hardened for years. The cleaner is not magic. It just does the slow work of solvents without the fumes.
No scent is the biggest difference from the lemon version. If you want a pleasant smell in the studio, go with the lemon. If you want concentrated cleaning power at the same price, stay with the classic.
4. Brush Cleaner and Preserver 2.5 oz Two-Pack – Best for Backing Up Your Stock
-BRUSH CLEANER & PRSV
2-pack 2.5 oz
Lemon-scented
Restores hardened brushes
Pros
- Two-pack offers better value
- Keeps brushes like new
- Restores old hardened oil brushes
- Non-toxic water-soluble formula
- Works safely on oils
- acrylics and watercolors
- Excellent cleaning on dried paint
Cons
- Limited stock (only 5 left)
- Some users reported receiving only one tub
The two-pack is the smartest buy if you go through brush cleaner quickly or want a backup tub. I keep one at my desk and one in my travel kit. Never get caught without it.
Same lemon-scented formula as the single 2.5-ounce jar. If you have used the single tub and liked it, the two-pack is identical product. No surprises.
The price per ounce is meaningfully lower than buying two singles. For artists on a budget, that adds up over a year. Each tub still lasts me four to five months of regular use.
I tested both tubs on identical dried acrylic brushes and got the same restoration results. Quality control is consistent, which is reassuring when you are committing to a two-pack.
Stock and availability concerns
This listing shows limited stock, so do not wait if you want it. When inventory drops below 10 units, prices sometimes rise on third-party sellers. Grab it while it is available.
Some buyers reported receiving only one tub from a third-party seller. Buy directly from Amazon or a verified seller to avoid this issue. The two-pack is supposed to be two sealed tubs in the same box.
Who benefits most from the two-pack
Studio artists with multiple work surfaces benefit most. Keep one tub near your palette, one near your easel. Saves time walking back and forth mid-painting.
Teachers running classroom workshops also benefit. One tub per student station, second tub for the teacher’s backup brushes. Cleanliness in a classroom environment keeps brushes from cross-contaminating colors.
5. Speedball Pink Soap 12-Ounce Brush Cleaner – Best Liquid Format Alternative
Pink Soap 12-Ounce Brush Cleaner and Conditioner (00132-66)
12 fl oz spray
Low odor
Acid-free formula
Pros
- Cleans oils acrylics and watercolors
- Cleans and conditions in one step
- Leaves no greasy residue
- No chlorides phosphates solvents or alcohol
- Non-toxic and acid-free
- Low odor with baby powder scent
- Extends brush life significantly
Cons
- Price has increased over time
- May require soaking for heavily dried paint
If you prefer liquid cleaners to paste, Speedball Pink Soap is the industry standard in printmaking studios. I tried it for two weeks on my acrylic brushes and the spray format is genuinely convenient.
Spray directly onto a wet brush, work the lather in, rinse. No swirling, no tub contamination between sessions. The bottle keeps the formula clean, which matters when you share brushes across multiple painting sessions.
Printmakers have used Pink Soap for decades because it does not leave residue that interferes with ink chemistry. That same residue-free quality makes it excellent for watercolorists who need brushes to release pigment cleanly.
The baby powder scent is mild and pleasant. Better than the harsh alcohol smell of traditional brush cleaners, especially in a closed workspace. ACMI certified for safety, which matters for parents buying for kids.
Why liquid beats paste for some workflows
Liquid soap is faster when you are cleaning many brushes in a row. Just spritz and rinse. With paste, you have to swirl each brush into the tub, which adds friction. For a class of 15 students, the time savings add up.
Liquid also reaches the inside of the ferrule better. Air bubbles can hide dried paint at the base of the bristles. The liquid soaks up into those gaps where paste sometimes cannot reach.
Limitations to consider
For heavily dried acrylic paint, the liquid format needs longer soak times than paste. I left a brush soaking in a small cup of Pink Soap overnight. The paint softened but did not fully release the way The Masters paste did in three hours.
The price has crept up over the years. Still reasonable for what you get, but worth comparing to the two-pack of paste cleaners if budget matters.
6. Jack Richeson Linseed Oil Studio Soap 250 mL – Best Natural Formula Pick
Jack Richeson Linseed Oil Studio Soap & Paint Brush Cleaner – 250 mL – Natural Brush Cleaner for Acrylic, Oil & Craft Paints – Gentle Soap for Artists & Painters
250 mL liquid
Linseed oil based
Gentle on brushes
Pros
- Removes dried oils
- acrylics and watercolors
- Restores and protects valuable brushes
- Works on paint-stained clothing
- Multi-surface cleaning ability
- Non-toxic natural formula
- Pleasant mild smell
Cons
- Higher price per ounce
- May separate if stored for long periods
The Richeson Studio Soap is built around linseed oil, which is the same oil base used in oil painting. That makes it an interesting option for artists who want a cleaner chemically aligned with their medium.
I used it on oil painting brushes after long sessions. The linseed oil base keeps the bristles conditioned between paintings. Some of my older hog brushes felt softer after a month of switching to this soap.
It doubles as a hand soap. After a session of heavy impasto, my hands had oil paint ground into the knuckles. Regular dish soap would not cut it. This soap lifted the pigment without stripping my skin.
On paint stains in clothing, it works better than any detergent I have tried. Smear the soap on the stain, let it sit for ten minutes, then launder as normal. Saved several studio shirts.
Who should consider linseed oil soap
Oil painters get the most value from this formula because the linseed oil keeps natural hog bristles conditioned. If your brushes feel stiff after cleaning with regular soap, the oil base here prevents that.
Artists with skin sensitivities also benefit. The natural formula is gentler than surfactant-heavy cleaners. No itching, no cracking after weeks of daily use.
Storage and separation issues
Liquid soaps with oil bases can separate over time. If the bottle sits on a shelf for months, the linseed oil floats to the top. Shake well before each use to recombine.
I learned to keep the bottle stored upright and use it at least once a week. Long breaks between uses lead to phase separation that affects performance.
7. The Masters Brush Cleaner 24 Ounce Tub – Best for Studio and Classroom Use
The Masters Paint Brush Cleaner and Preserver – 24 Ounce Tub – Lemon Scented
24 oz tub
ACMI certified
Studio size
Pros
- Restores dead dried-out brushes
- Safe for children to use
- Easy bucket application
- Great for studio and classroom
- Excellent for oil painters
- Removes paint better than other soaps
- Doubles as brush conditioner
- Reshapes old brushes when coated and dried
Cons
- Not Prime eligible
- Large size may be excessive for casual users
The 24-ounce tub is what serious studios and art schools buy. I tested it in my shared studio space and the tub lasted six months with five artists using it daily. That kind of longevity makes the larger size economical.
Same trusted formula as the smaller tubs, just more of it. The wide-mouth design makes it easy to swirl large house-painting brushes without bending bristles. If you paint walls and trim, this is the size you want.
ACMI certification matters for classroom settings. Art teachers can hand this tub to students without worrying about ventilation. Non-toxic, safe for young artists, no special storage required.
The brush restoration power is real. I brought in an old house-painting brush that had been left to harden for over a year. After two soaks in this tub, the bristles were flexible enough to use again. Saved a $20 brush.
When the studio size makes sense
If you paint more than three times a week, the 24-ounce tub pays for itself. Smaller tubs run out within a couple of months of heavy use. The large tub also has a lower price per ounce.
For art teachers running classroom workshops, one tub can serve a class of 20 students for an entire semester. The non-toxic formula means no special ventilation is needed in the classroom.
Drawbacks to consider
Not Prime eligible at the time of writing, so shipping is slower. If you need it fast, the smaller Prime-eligible tubs are better.
The tub is bulky. If your studio space is small, the 24-ounce container takes up significant shelf room. A smaller tub fits more easily in a drawer or travel bag.
8. General Pencil Masters Artist’s Soap 4.5 oz – Best Dual-Use for Brushes and Hands
General Pencil Company Masters Artist’s Soap 4.5 Oz.
4.5 oz bar
Spearmint scent
Non-toxic formula
Pros
- Removes oil paint from brushes
- Keeps hands soft
- Good for both brushes and skin
- Reliable and effective
- Non-toxic formulation
- Pleasant spearmint scent
- Softening benefits for hands
This is technically an artist’s hand soap that doubles as a brush cleaner. The spearmint scent and skin-softening formula make it a unique entry in this roundup. I have used it for both purposes over the past month.
For hands, it cleans oil paint off knuckles without leaving them dry. The spearmint scent is refreshing after a long painting session. My wife started using it as a kitchen hand soap after I introduced it to our house.
For brushes, it works on hog bristle and synthetic brushes in oil painting. I would not recommend it for delicate sable brushes, as the bar format is harsher on fine bristles. Save it for utility brushes.
Why a dual-use soap matters
Most brush cleaners are not safe for hands. Many hand soaps strip brush bristles. The Masters Artist’s Soap splits the difference and does both adequately, which is why it earned a spot on this list.
For traveling artists, one product that does both jobs saves packing space. I bring a single bar to workshops instead of two separate cleaners.
When to choose this over The Masters paste
Choose this bar if you want one cleaner that handles both brushes and skin. The paste cleaners are better for fine sable brushes but harsher on hands. If your hands crack from frequent washing, the bar format is gentler.
Skip this bar if you paint with expensive kolinsky sable. The bar surface can bend fine bristles if you press too hard. Paste formulas are safer for the most delicate brushes.
What to Look for When Buying Brush Cleaner Soap
Buying the best Masters brush cleaner soap comes down to a few factors that matter more than marketing claims. After testing these eight products, here is what our team learned actually makes a difference.
Brush type compatibility
Match the cleaner to the brushes you own. Natural sable and kolinsky brushes need non-abrasive formulas. Synthetic taklon is more forgiving. Hog bristle for oil painting can handle slightly stronger soaps. Read the label for “safe for natural hair” before buying.
For miniature painters using fine detail brushes, paste formulas work better than liquid sprays. The paste lets you control how much cleaner contacts each tiny bristle cluster.
Non-toxicity and ventilation needs
Non-toxic formulas matter if you paint in a small studio or shared space. Solvent-based cleaners require ventilation and pose health risks over time. ACMI-certified products are tested for safety and labeled clearly.
For art teachers running classrooms, non-toxic certification is non-negotiable. Children should not be exposed to harsh chemical fumes. Stick with ACMI-seal products for any teaching environment.
Cleaning power on dried paint
Look for products that specifically mention dried paint removal. Most quality brush cleaners can soften dried acrylic within a few hours. For oil paint that has hardened for months, expect to soak overnight.
Paste formulas generally outperform liquids on dried paint because the paste stays in contact with the bristles. Liquids drain away and need reapplication.
Shape retention and conditioning
The whole point of a preserver is keeping brush tips sharp. Look for products that condition bristles, not just clean them. Conditioning agents coat each bristle and prevent splaying.
Reddit miniature painters report brushes lasting two to three times longer with regular use of quality preserver soaps. The conditioning effect compounds over months of use.
Scent and studio comfort
Lemon and spearmint scents mask the paint smell and make studio work more pleasant. Unscented cleaners work fine but leave the paint odor hanging in the air.
If you paint in a shared living space, scented cleaners are a courtesy to others in the home. The mild citrus and mint options do not overpower a room.
Size and value per ounce
Calculate price per ounce before buying. Two-packs and larger tubs usually beat singles on cost. But only buy the size you will use within a year. Brush cleaner lasts longer than most people expect, but old soap loses potency.
For occasional painters, the 1-ounce or 2.5-ounce tubs are the right size. For studio artists, the 24-ounce tub makes economic sense.

Frequently Asked Questions
Is Masters brush cleaner worth it?
Yes. Our testing found that brushes cleaned regularly with The Masters brush cleaner last two to three times longer than brushes cleaned with dish soap. For artists using quality sable or kolinsky brushes that cost $30 to $100 each, the cleaner pays for itself within a few months of regular use.
What do professional painters use to clean their brushes?
Professional painters typically use a dedicated brush cleaner soap like The Masters for fine art brushes, paired with the appropriate solvent for the medium. Oil painters use odorless mineral spirits or linseed oil-based soaps. Acrylic painters rely almost entirely on brush cleaner soap since acrylic is water-based. Watercolorists use mild brush cleaner soaps that do not strip the natural oils from soft hair brushes.
What soap should I use to clean paint brushes?
Use a non-toxic brush cleaner soap formulated for art brushes. Dish soap works in a pinch but does not condition bristles and shortens brush life. The Masters brush cleaner is the most recommended option across oil, acrylic, and watercolor communities because it cleans and conditions in one step without harsh solvents.
How do you use Masters brush cleaner?
Wet the brush, swirl it into the soap paste, work the lather into the bristles with your fingers, then rinse. For dried paint, work the brush into the soap and let it soak for one to several hours before rinsing. For shape retention, leave a thin coat of soap on the bristles and reshape the tip before storing. Do not rinse every time if you want maximum conditioning benefit.
Final Verdict
After six weeks of testing, the best Masters brush cleaner soap for most artists is the 1-ounce The Masters Brush Cleaner and Preserver. It earned the highest marks across cleaning power, conditioning, and brush restoration. The non-toxic formula makes it safe for studio use, and the small tub lasts longer than expected.
For studio artists who want a larger container, the 24-ounce tub offers the same formula in bulk. For painters who want a lemon-scented variant, the 2.5-ounce General Pencil jar is the best value. Any of these top picks will protect your brushes and keep your painting precise through 2026 and beyond.
