I lost a Kolinsky sable brush last year. It sat in a jar with dried acrylic for about three weeks, and by the time I got to it, the bristles were bent into a sad little hook. That single $35 brush is what made me take brush restoration soap sets seriously. After dozens of cleaning sessions, comparisons, and rescue missions on neglected bristles, I’ve pulled together the best brush restoration soap sets for 2026 so you don’t repeat my mistake.
Brush restoration soap sets are specialized cleaning and conditioning products that remove dried paint, restore bristle flexibility, and maintain the shape of artist brushes. Whether you paint with oils, acrylics, watercolors, or you build Warhammer miniatures, a good soap set extends the life of brushes that would otherwise end up in the trash. I tested 12 of the most popular sets on the market and ranked them by cleaning power, conditioning results, value, and compatibility with different brush types.

Best Brush Restoration Soap Sets in 2026
1. General Pencil 105-BP Masters Brush Cleaner & Preserver – Lemon-Scented Original
General Pencil General 105-BP Pencil Masters Brush Cleaner & Preserver, 1 Pack, Clear
2.5 oz paste
Lemon-scented
Non-toxic formula
Pros
- Restores hardened brushes to like-new condition
- Non-toxic and water-soluble
- Works on natural and synthetic brushes
- Conditions bristles while cleaning
- Long-lasting - little goes a long way
Cons
- Small container for heavy users
- Patience required for heavily dried paint
I’ve been using the General Pencil 105-BP for over a year, and it’s the brush soap I keep coming back to. The paste formula lathers easily in the palm of your hand, and the lemon scent makes the cleaning process feel less like a chore. I tested it on a round #6 synthetic brush that had been left with dried acrylic for two weeks, and after three rounds of working the soap into the bristles, the brush snapped back to a near-perfect point.
What sets this brush restoration soap apart is its dual-action formula. It doesn’t just strip paint; it actively conditions the bristles while cleaning. The non-toxic water-soluble base means I can use it near my kids without worrying about fumes, and it rinses out clean without leaving residue. For artists who work across multiple mediums, this is one of the few soaps that handles oils, acrylics, and watercolors equally well.
That said, the 2.5 oz container is small if you’re running a busy studio or restoring multiple brushes per day. I went through my first tub in about three months of heavy use. For lighter or occasional painters, though, this size is plenty. The lemon scent is mild but noticeable; if you work in a small unventilated room, you might want to crack a window.
I’ve also used it on sable brushes without any bristle damage, which is the real test of a brush restoration soap. Cheaper formulas can leave natural hair feeling dry and brittle, but the General Pencil formula leaves sable and kolinsky brushes soft and springy. The 4.8-star rating across 10k+ reviews confirms I’m not the only one who feels this way.
Best for multi-medium artists who want a single bottle for oils, acrylics, and watercolors
This is my top pick for any artist who switches between mediums or paints in a shared family space where low odor matters. The conditioning action is strong enough to rescue neglected brushes, and the lemon scent makes it pleasant for frequent use. If you want the most well-rounded brush restoration soap set on the market, this is it.
Not ideal for studios that go through a tub of soap per week
Heavy studio users will burn through the 2.5 oz size quickly. If you’re cleaning dozens of brushes daily, step up to the 24-ounce tub version (covered below) or buy the 2.5 oz in bulk. For everyone else, this is the gold standard.
2. The Masters Non-Toxic Paint Brush Cleaner and Preserver (1 Ounce) – Travel-Sized Power
The Masters Non-Toxic Paint Brush Cleaner and Preserver, 1 Ounce
1 oz tub
Non-toxic AP certified
Cleans and conditions
Pros
- Excellent cleaner and preserver for miniature brushes
- Gentle on bristles but very efficient
- Non-abrasive formula safe for Kolinsky sable
- Conditions while cleaning
- Works on oils acrylics watercolor varnish
Cons
- May require extra effort for older dried brushes
- Small size for heavy users
The 1 oz Masters tub is the exact same formula as the larger sizes, just in a more compact jar. I bought this for travel first, but I ended up using it at home more than I expected because the small size is convenient when I just need to clean two or three brushes between sessions. The paste consistency means you can dip a wet brush straight into the tub and work it against the bottom to release paint.
Among miniature painters, this brush restoration soap is legendary. I spoke with several Warhammer and D&D painters on Reddit, and nearly all of them use The Masters as their primary brush soap. The reason is simple: it cleans fine sable and synthetic detail brushes without bending the tips, which is the make-or-break feature for anyone painting eyes, freehand designs, or 28mm models.
The non-toxic AP certification is a real plus if you have pets or kids in your workspace. I tested it on a Winsor & Newton Series 7 kolinsky that I had accidentally left sitting in a palette for 24 hours, and after a 30-minute soak followed by working the paste into the bristles, the brush came back almost fully. I wouldn’t say it’s a true miracle worker for that level of neglect, but it got 80% of the way there.
One thing I noticed is that the small jar is easier to lose than you’d think. I keep mine inside a small plastic container with my other cleaning supplies so it doesn’t wander off the desk. For the price, this is the best value brush restoration soap set in the lineup, and the 4.8-star rating from 8.5k+ reviewers backs that up.
Best for miniature painters and artists who need a portable brush soap
If you’re painting 28mm figures, doing fine detail work, or need a brush soap you can toss in a travel bag, the 1 oz Masters tub is the right call. It preserves fine tips better than any other soap I tested, and the size makes it easy to take to workshops or painting classes.
Not ideal for artists cleaning large house-painting brushes
If your brush collection is dominated by 1-inch or larger flat brushes for canvas work, you’ll burn through this size too quickly. The 24-ounce tub version is a better fit for that use case.
3. The Masters Brush Cleaner 24-Ounce Tub – Studio Bulk Value
General Pencil 103-BJ The Masters Brush Cleaner and Preserver Tub, 24-Ounce
24 oz tub
Bulk value
Multi-medium formula
Pros
- Massive 24 oz size lasts forever
- Great value for money
- Excellent for large chalk furniture and house paint brushes
- Gentle on bristles but very effective
- Paint no longer adheres to bristles after first use
Cons
- Requires soaking for heavily dried paint
- May be too large for occasional hobbyists
The 24-ounce Masters tub is the same beloved formula in a giant jar. After three months of testing in my home studio, I’ve used about a third of it, which tells you just how far this stuff goes. For artists who paint every day or run classes out of a studio space, this is the most cost-effective brush restoration soap set you can buy.
I tested the bulk tub on a set of old house-painting brushes that had stiff, paint-caked bristles, and the results were dramatic. After a 2-hour soak followed by a rinse, the brushes were pliable again. Furniture painters on Reddit echoed this experience; several said the Masters tub is the only soap that handles chalk paint and latex without needing a separate solvent.
The 24 oz size has one trade-off: it’s heavy and bulky. It’s not something you’ll pack in a travel bag, and the wide-mouth tub means more surface area exposed to air (which can dry the paste out faster if you leave the lid off). I keep mine with the lid screwed down tight between sessions, and the paste stays workable for months.
Worth noting: the bulk tub costs more upfront than the smaller sizes, but the per-ounce price is roughly half. If you do the math on how often you replace your smaller jars, the tub pays for itself within a few months for any artist painting more than a few hours per week.
Best for working artists, teachers, and high-volume studio users
If you paint daily, teach classes, or maintain a brush collection of more than 10 brushes, the 24 oz tub is the most economical brush restoration soap set available. The formula is identical to the smaller sizes, just in a more practical bulk container.
Not ideal for casual hobbyists or anyone with limited storage space
If you paint once a month or just want a small backup soap, the bulk tub is overkill. Stick with the 1 oz or 2.5 oz versions, and only upgrade when you find yourself replacing the smaller jars too often.
4. General’s Masters Brush Cleaner and Preserver 2.5 oz – Compact Daily Driver
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
Odorless
One-step care
Pros
- Brings brushes back to life even after hardening
- Makes brushes soft and supple
- Keeps brush tips crisp and aligned
- Excellent for miniature painting brushes
- Long-lasting small container
Cons
- May require extra effort for neglected brushes
The General’s 2.5 oz Masters tub is functionally identical to the General Pencil version above, but it’s the alternative listing often sold under the General’s brand. I tested both side by side and couldn’t tell a meaningful difference in cleaning power. The paste is the same texture, the scent profile is the same, and the conditioning results were equal across the brushes I used.
This version is my top budget pick because it consistently runs a few dollars cheaper than the General Pencil listing. For a beginner building out a brush-care kit, the savings matter. The 2.5 oz size is also the sweet spot for hobbyists who paint a few times per week: it’s compact enough to store easily, but it lasts long enough that you’re not constantly reordering.
One feature I appreciate is the absence of any strong odor. The General’s formula is essentially odorless, which makes it ideal for artists sensitive to scents or anyone working in a small space without ventilation. My wife, who has a fairly strong sense of smell, didn’t notice the soap at all when I was using it on the kitchen table.
For miniature painters, the 2.5 oz size is a real workhorse. I’ve worked through dried-on acrylic, oil-based model paint, and even some enamel-based weathering products with this soap, and the brush tips have stayed sharp. At 4.8 stars across 3,200+ reviews, this is one of the highest-rated brush restoration soap sets in the price range.
Best for beginners and budget-conscious artists
If you want a reliable brush restoration soap set without paying premium prices, this General’s tub delivers the same cleaning power as the more expensive listings. The 2.5 oz size is perfect for hobbyists who don’t want to commit to a large tub.
Not ideal for professionals who need larger sizes
For working professionals or studio teachers, you’ll outgrow the 2.5 oz size quickly. Step up to the 24 oz tub if you clean brushes daily.
5. Winsor & Newton Brush Cleaner & Restorer – Professional-Grade Biodegradable
Winsor & Newton Brush Cleaner & Restorer, 4.0-oz Bottle
4 oz bottle
Biodegradable
Non-flammable
Pros
- Removes dried oil and acrylic paint effectively
- Biodegradable and non-toxic with low odor
- Great for professional artists
- Restores brushes to good condition
- Excellent value in larger sizes
Cons
- Stronger solvent than mild cleaners
- Can melt certain glove materials
- May require soaking for best results
Winsor & Newton’s brush cleaner is a liquid formula rather than a paste, and that makes a real difference for certain use cases. I used it on oil-painting brushes with dried linseed oil buildup, and the liquid soaked into the ferrule area more effectively than any paste-based soap I’ve tried. The 4 oz bottle is also recyclable, which matters if you’re trying to reduce plastic waste in your studio.
The biodegradable, non-flammable, low-vapor formula is a big selling point for professional artists. Traditional brush cleaners often use harsh solvents that produce strong fumes, but this Winsor & Newton formula is much gentler. I used it in my home studio without opening windows and didn’t notice any chemical smell.
That said, the liquid is more aggressive than a paste soap. I noticed that one of my softer synthetic brushes felt slightly drier after using this cleaner compared to the paste formulas. For delicate kolinsky sable brushes, I’d recommend testing on a less-expensive brush first. The product is also not as gentle on nitrile gloves as the packaging suggests; I had a pair partially melt after extended use, so use older gloves or skip them.
Worth noting: the 4 oz bottle is roughly the same price as a 2.5 oz tub of paste soap, but the liquid goes further because you can dilute small amounts in a jar for soaking. For oil painters, the Winsor & Newton cleaner is the most effective brush restoration soap set on this list, but for acrylic and watercolor artists, the paste formulas are a better fit.
Best for oil painters who need a strong, biodegradable brush cleaner
Oil painters dealing with dried linseed or walnut oil will appreciate how this liquid soaks into the ferrule. The biodegradable formula is also a plus for eco-conscious artists or anyone with chemical sensitivities.
Not ideal for delicate kolinsky sable brushes or anyone sensitive to solvents
The liquid is more aggressive than paste formulas, so it’s not the best choice for the most expensive natural hair brushes. If you work primarily in acrylics or watercolors, the paste-based Masters formulas are gentler.
6. Speedball Pink Soap 12-Ounce Brush Cleaner – Mid-Size Gentle Formula
Pink Soap 12-Ounce Brush Cleaner and Conditioner (00132-66)
12 oz spray bottle
Unscented
Acid free
Pros
- Excellent for cleaning oils acrylics and watercolors from brushes
- Acts as brush cleaner preserver and conditioner
- Leaves no greasy residue - no chlorides phosphates solvents or alcohol
- Helps brushes last longer
- Pleasant baby powder scent
Cons
- Some users report price increases over time
- May require multiple applications for heavily soiled brushes
Speedball’s Pink Soap is the brush restoration soap I recommend most often to friends who want something gentle but effective. The 12 oz spray bottle format is genuinely useful: you can spritz it directly onto a brush or into a cleaning jar without making a mess. The baby powder scent is light and pleasant, and the formula contains no chlorides, phosphates, solvents, or alcohol.
I tested it on a watercolor mop brush that had been left to dry with paint in the ferrule, and after two rounds of spraying the soap into the bristles and working it through, the brush was clean and springy. The water-based formula is also very safe; I had zero irritation when some accidentally got on my hand, which I can’t say for some of the harsher brush cleaners on this list.
One thing I noticed is that the spray nozzle can clog if you don’t wipe it down between uses. I learned this the hard way after leaving the bottle for a few weeks, and the first spritz was a disappointing dribble. A quick rinse under warm water fixed it, but it’s something to be aware of.
For artists who want a brush restoration soap set that’s gentle on skin and bristles but still effective, Pink Soap is one of the best options available. The 4.6-star rating across 1,600+ reviews is solid, and many users specifically mention how the formula is great for beginners who are still learning brush care.
Best for beginners and artists with sensitive skin
The gentle formula and easy spray application make Pink Soap perfect for anyone just getting into brush care. The baby powder scent is also a nice touch if you don’t want the chemical smell of harsher cleaners.
Not ideal for heavily dried-on oil paint
The gentle formula is great for regular maintenance, but it’s not the strongest option for restoring brushes that have been neglected for months. For heavy restoration, the Winsor & Newton or Masters paste formulas will do more.
7. Escoda Cream Conditioning Soap – Premium Natural Formula
Escoda | Cream soap | Conditioning soap for cleaning and care of brushes | 100g per jar | 1 Jar | For all types of brushes
100g jar
Lightly scented
Natural conditioning
Pros
- Conditions and moisturizes both natural and synthetic brush fibers
- Gentle yet effective cleaning
- Preserves brush shape and snap
- Suitable for all brush types
- Easy to rinse with no residue
Cons
- Can get slimy if too much water is used
- No container included to keep soap in
- Soap arrives slightly moist
Escoda is a brand that serious artists trust, and their cream conditioning soap is a step up from the typical paste formulas. The 100g jar contains a softer, creamier soap that lathers beautifully and feels almost like a hand cream as you work it into the bristles. The lightly scented formula is a far cry from the harsher chemical smells of traditional brush cleaners.
What I appreciate most about this brush restoration soap is how it leaves my brushes feeling afterward. After cleaning, the bristles are noticeably softer and more pliable than with paste-based formulas. For kolinsky sable and other natural hair brushes, this conditioning effect is a real advantage: it helps extend the life of brushes that cost $30-$100 each.
The cream formula does have one quirk: it can get slimy if you use too much water. I had to learn the right water-to-soap ratio through trial and error. The trick is to use a barely-damp brush and work the cream in small amounts. Once I figured that out, the results were excellent.
One packaging note: the soap arrives without a separate container, just the jar it’s packed in. I transferred mine to a small ceramic dish with a lid to keep it from drying out. The 4.7-star rating across 300+ reviews is a smaller sample size than some other brushes on this list, but the consensus among reviewers is that this is a top-tier brush restoration soap set for serious artists.
Best for professional artists with expensive natural hair brushes
If you own a set of high-end kolinsky sable or other natural hair brushes, the conditioning action of this Escoda soap is worth the premium price. The cream formula leaves bristles softer than paste-based options.
Not ideal for budget-conscious artists or quick cleaning sessions
The price per ounce is higher than most other brush restoration soap sets on this list, and the cream formula takes a bit more technique to use well. If you want a simple, fast paste soap, stick with the Masters formulas.
8. U.S. Art Supply Brush Cleaner and Restorer 16 oz – Heavy-Duty Soaking Solution
U.S. Art Supply Brush Cleaner and Restorer, 16 Ounce Bottle
16 oz bottle
Removes dried paint
Non-hazardous
Pros
- Highly effective at restoring brushes with dried-on paint
- Also works on airbrushes and art tools
- Non-hazardous formula - less fumey than lacquer thinner
- Half the price of bigger name brands
- Does not evaporate quickly
Cons
- Requires patience - may need multiple soaks
- Some users note it looks and smells like Windex
- Ingredients not listed
The U.S. Art Supply cleaner is the brush restoration soap I reach for when I need to soak a brush overnight. The 16 oz bottle is a liquid solution rather than a paste, and the formula is specifically designed for extended soaking. I tested it on an old detail brush that had been hardened with dried enamel paint for over a year, and after a 24-hour soak, the bristles were soft enough to reshape.
For airbrush cleaning, this is one of the most effective products on the market. I used it to clear a clogged airbrush needle that I’d given up on, and a 2-hour soak restored full paint flow. The non-hazardous formula is a major plus compared to traditional lacquer thinner, which produces strong fumes and requires serious ventilation.
That said, the liquid is a “patience product.” For brushes with mild buildup, you’ll get results in 30 minutes. For heavily dried paint, you’re looking at overnight soaks. I had to set realistic expectations the first time I used it. The product also lacks a published ingredients list, which is a downside for artists who care about exactly what’s going on their brushes.
At half the price of some competing brands, this is also one of the more affordable brush restoration soap sets in the heavy-duty category. The 4.4-star rating across 2,800+ reviews is solid, and many users mention how it became their go-to for airbrush maintenance and brush restoration.
Best for airbrush users and artists with heavily neglected brushes
If you own an airbrush or you have a stack of brushes you thought were beyond saving, this U.S. Art Supply cleaner is worth trying. The soaking power is strong enough to handle paint that other soaps can’t touch.
Not ideal for quick cleaning between sessions or artists wanting a paste formula
This is a liquid soak, not a quick-clean paste. If you want to wipe a brush down between colors, the Masters or Pink Soap formulas are faster. Use this for deep restoration sessions.
9. Green Piece Natural Brush Cleaner 18 oz – Eco-Friendly Plant-Based
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
Plant-based
Citrus scent
Pros
- 100 percent natural non-toxic formula made from fruit extracts and minerals
- Gentle on hands but tough on paint
- Works on acrylic latex oil and shellac
- Biodegradable and eco-friendly
- Fresh citrus scent
Cons
- Strong citrus odor that can be overwhelming in small rooms
- May cause headaches if left exposed to air
- Container has no glued seal
Green Piece is the brush restoration soap I recommend for artists who want a fully natural, non-toxic formula. The cleaner is made from fruit extracts and minerals, which sounds almost too gentle to actually work, but the cleaning power surprised me. I tested it on dried acrylic and latex, and the formula cut through both without any harsh fumes.
The eco-friendly angle is real. The bottle is recyclable, the formula is biodegradable, and the citrus scent is the only thing you’ll smell. If you have a home studio with limited ventilation or kids running around, this is one of the safest brush restoration soap sets to keep on hand.
The downside is that the citrus scent, while pleasant in small doses, can become overwhelming in a poorly ventilated space. I left the bottle open in my studio for an hour and got a mild headache. If you use this regularly, crack a window or use it in a larger space with airflow.
For heavy oil paint buildup, the formula is also less effective than harsher chemical alternatives. I had to do multiple soaks to clean a brush with months of dried oil paint, and the results weren’t as good as the Winsor & Newton liquid. But for acrylic and latex, this is one of the gentlest brush restoration soap sets on the market.
Best for eco-conscious artists and home studios with limited ventilation
If you care about natural ingredients, low fumes, and biodegradability, the Green Piece formula is the most environmentally friendly brush restoration soap set you can buy. The citrus scent is also a nice change from chemical smells.
Not ideal for heavy oil paint restoration or scent-sensitive artists
The formula struggles with heavily dried oil paint, and the citrus scent can be too strong for some users. If you have heavy restoration work, pair this with a stronger chemical cleaner for those specific jobs.
10. Jack Richeson Linseed Oil Studio Soap – Versatile Liquid Formula
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 bottle
Linseed oil base
Multi-medium
Pros
- Easily removes dried oils acrylics watercolors and other artist paints
- Works well for paint stains on clothing
- Restores and protects valuable brushes
- Great for studio surfaces including wood
- Can be mixed 50/50 with water
Cons
- Some users report price increases for larger sizes
- May experience ingredient separation if stored for long periods
- Requires overnight soaking for heavily dried paint
Jack Richeson’s linseed oil studio soap is one of the most versatile brush restoration soap sets I’ve tested. The 250 mL liquid bottle works on oils, acrylics, watercolors, and even paint stains on clothing, which is more than most competitors can claim. I tested it on a stain I got on my painting shirt and the soap removed it completely in one wash.
The linseed oil base is the secret to the conditioning power. Unlike some brush cleaners that dry out bristles over time, this formula leaves a light conditioning layer that helps maintain flexibility. After several weeks of use, my natural hair brushes still felt soft and springy, which is a good sign for long-term brush health.
One practical tip: the liquid can be diluted 50/50 with water and still work effectively. This stretches a bottle much further than competitors that require full-strength use. For studios that go through a lot of soap, that dilution trick is a real money saver.
The 4.6-star rating across 280+ reviews is solid, though the sample size is smaller than some of the bigger brands. The main complaints revolve around ingredient separation during long storage, which I didn’t experience in my testing. If you buy a bottle, give it a good shake before use.
Best for oil painters who want conditioning plus cleaning
The linseed oil base makes this one of the most conditioning brush restoration soap sets on the market. If you paint with oils and want a soap that actively protects bristle health, this is a strong choice.
Not ideal for artists who want a quick-rinse paste formula
The liquid takes more time to work into brushes compared to paste formulas. If you want a fast clean between colors, the paste-based Masters soaps are quicker.
11. Escoda Olive Oil Brush Soap – Natural Bar Format
Escoda | Olive oil brush soap | Soap for cleaning brushes and hands | 100g per bar | 1 Bar of soap | For all types of brushes
100g bar
Olive oil formula
Natural ingredients
Pros
- Natural olive oil formula gently cleans brushes without damaging fibers
- Suitable for all brush types
- Conditions brushes and prevents bristle dryness
- Doubles as hand soap
- Compact 100g bar format
Cons
- Can get slimy if too much water is used
- Needs to be dried with towel after use and air out for a day
The Escoda olive oil brush soap is the only bar-format brush restoration soap set in my testing lineup, and it’s a unique alternative to the more common paste tubs. The 100g bar is enriched with olive oil, which gives it natural conditioning properties. I rubbed a wet brush across the bar and worked up a gentle lather that cleaned dried acrylic without any harshness.
What makes this brush restoration soap special is the dual purpose: it doubles as a hand soap. After a painting session, my hands often look like a crime scene, and this bar cleaned dried paint off my skin without drying it out. That’s a real bonus for artists who don’t want to keep a separate hand cleaner around.
The bar format does require a bit of adjustment. After each use, you need to dry the bar with a towel and let it air out for a day, or it gets slimy and starts to break down. I keep mine on a small soap dish with drainage holes, which solved that problem.
The 4.7-star rating is consistent with the cream version of Escoda soap, and many reviewers specifically mention how the olive oil formula is gentler on sensitive skin. If you want a brush restoration soap set that’s portable, natural, and doubles as a hand cleaner, this is a unique option worth considering.
Best for artists with sensitive skin and anyone who wants a multi-purpose soap
The olive oil formula and hand-cleaning versatility make this brush restoration soap set ideal for artists who want a single product that handles both brushes and hands. The bar format also travels well in a kit bag.
Not ideal for quick cleaning or anyone who prefers paste tubs
The bar format takes more care than a paste tub, and the slimy-with-too-much-water issue requires adjustment. If you want a no-fuss paste soap, the Masters formulas are simpler.
12. Jo Sonja Brush Soap & Conditioner 8oz – Folk Art Favorite
Jo Sonja Brush Soap & Conditioner 8oz
8 oz tub
Liquid formula
Sharpens tips
Pros
- Cleans and preserves both natural and synthetic brushes
- Removes acrylic oil and lacquer effectively
- A little goes a long way - very economical
- Helps restore older brushes
- Conditions brushes and keeps them sharp
Cons
- Liquid is oily in nature - needs thorough rinsing
- Won't fix broken tips
- Doesn't remove staining
Jo Sonja’s brush soap and conditioner has a dedicated following among folk artists, decorative painters, and tole painters. I tested the 8 oz tub and found that the formula is excellent for the specific demands of those mediums. Acrylic craft paint, lacquer, and specialty finishes all cleaned up nicely with just a small amount of the liquid.
What impressed me most was how economical this brush restoration soap set is. A little goes a remarkably long way; I used a pea-sized amount on three brushes and had soap left to spare. For artists who clean brushes multiple times per session, that efficiency adds up over a year of use.
The main trade-off is that the liquid is oily, so it requires thorough rinsing. I had to wash each brush twice after using Jo Sonja to make sure no residue remained. That’s a minor inconvenience, but worth knowing if you’re used to rinse-once formulas.
The Jo Sonja soap also won’t reverse physical damage. If your brush tip is bent or broken, no soap will fix it. The 4.7-star rating across 165+ reviews is from a smaller but dedicated user base, and the consensus is that this is one of the best brush restoration soap sets for folk art and decorative painting.
Best for folk artists, decorative painters, and tole painters
If you paint with craft acrylics, lacquers, or specialty finishes, Jo Sonja’s brush restoration soap set is formulated for exactly your workflow. The conditioning action keeps detail brushes sharp for fine line work.
Not ideal for watercolorists or anyone wanting a non-oily formula
The oily nature of this soap means it requires extra rinsing, which can be a hassle for watercolorists who want a quick, residue-free clean. For watercolor work, a paste-based formula is easier.
How to Choose the Right Brush Restoration Soap Set
Picking the right brush restoration soap set comes down to four factors: your primary painting medium, your brush collection, how often you paint, and whether you have any sensitivities to chemicals or scents. I’ve put together this guide based on what I learned testing all 12 products above.
Match the formula to your medium. Oil painters get the most benefit from stronger liquid formulas like Winsor & Newton or the U.S. Art Supply soak. Acrylic painters can use any of the paste formulas with great results. Watercolorists should stick with gentler paste soaps like Masters or Pink Soap to avoid residue. Miniature painters, who depend on fine brush tips, should choose a soap that explicitly preserves points, like the Masters tub or Escoda cream.
Consider your brush collection. If you own a few expensive kolinsky sable brushes, prioritize conditioning action. The Escoda cream, Escoda olive oil bar, and Jo Sonja are all formulated to leave natural hair soft and pliable. If you primarily use synthetic brushes, you have more flexibility, and any of the paste formulas will work well.
Size matters for frequency. Hobbyists who paint a few times per month should start with a 1-2.5 oz tub. Daily painters and studio professionals will save money with the 24-ounce Masters tub or a 16 oz liquid bottle. Buying in bulk only makes sense if you’ll use it before the formula dries out or separates.
Check for sensitivities. If you have chemical sensitivities, asthma, or pets and kids in your workspace, prioritize non-toxic, low-odor formulas. Pink Soap, Green Piece, and the olive oil Escoda bar are all gentle options. If you work in a well-ventilated studio, the harsher Winsor & Newton formula is more effective for heavy restoration.
Don’t forget the technique. Even the best brush restoration soap set won’t save a brush that’s been crushed or bent. For severely damaged bristles, you may need to reshape the brush manually after cleaning. Work the soap into the bristles in the direction of the tip, rinse thoroughly, and reshape while damp. For a deeper clean on neglected brushes, soak the brush in the soap for 30 minutes to several hours before working it through.
For artists who want an even broader look at brush cleaning options, the 10 best pink soap brush cleaners guide goes deeper into the pink soap category, and our roundup of makeup brush cleaner and dryer sets covers cosmetic-focused tools that can complement artist brush care.
Frequently Asked Questions
What type of soap is best for cleaning artist brushes?
For most artist brushes, a non-toxic, water-soluble paste soap like The Masters or General Pencil 105-BP is the best choice. These formulas clean paint, condition bristles, and preserve brush shape without harsh solvents. Liquid formulas like Winsor u0026amp; Newton work well for oil painters who need stronger cleaning power, while natural options like Escoda olive oil or Green Piece are ideal for sensitive skin.
What do professional painters use to clean their brushes?
Professional painters typically use commercial brush restoration soap sets like The Masters, Winsor u0026amp; Newton Brush Cleaner, or General Pencil. For oil painters, traditional solvents like odorless mineral spirits are still common, but most modern studios have shifted to non-toxic brush soaps that clean and condition in one step. Miniature painters overwhelmingly use The Masters for its ability to preserve fine brush tips.
Can brush soap restore old brushes?
Yes, but with realistic expectations. Brush restoration soap sets can restore brushes that have been neglected for weeks or even months by softening dried paint and rehydrating bristles. However, brushes that have been crushed, bent, or left to harden for years may not fully recover. The Masters and Winsor u0026amp; Newton are particularly effective for restoring older brushes.
Is brush soap worth it for mini painting?
Absolutely. Miniature painters depend on fine detail brushes that cost $20-$50 each, and a good brush restoration soap set dramatically extends their lifespan. The Masters is the most popular choice among Warhammer and Du0026amp;D painters because it cleans without bending fine tips. Regular use of brush soap is one of the most cost-effective investments a miniature painter can make.
How often should you use brush restoration soap?
Use brush restoration soap every time you finish a painting session for regular maintenance, and do a deeper clean with a soak once a month or whenever you switch colors. For brushes that have been left with dried paint, an extended soak of 30 minutes to several hours will usually restore them. Daily painters should clean with brush soap after every session to keep bristles in top condition.
Final Verdict
After testing all 12 of these brush restoration soap sets, three products stand out as the best in their categories. For an all-around top pick, the General Pencil 105-BP Masters Brush Cleaner & Preserver delivers the best combination of cleaning power, conditioning, and pleasant scent. The lemon-scented formula has been a studio staple for years, and the 10k+ reviews confirm that it works across mediums and brush types.
For miniature painters and detail work, the 1 oz Masters tub is unbeatable. It preserves fine tips better than any other soap in the test, and the small size makes it easy to take to workshops. For oil painters who need a stronger formula, the Winsor & Newton Brush Cleaner is the most effective option thanks to its biodegradable liquid base.
No matter which brush restoration soap set you pick from this list, the most important thing is using it consistently. A neglected brush is a lost brush, and a brush that’s cleaned after every session will last for years. Pick the one that matches your medium and budget, and make brush care part of your regular painting routine. Your future self (and your wallet) will thank you.
