Quick answer: If you want a wire brush to clean paint brushes, think in terms of a small kit rather than one tool. A brush comb such as the ROLLINGDOG 4-in-1 stainless comb or the Wooster two-sided brass and steel comb handles bristles; a three-material set like the IEGREMAR nylon, brass and stainless trio covers ferrules, palette knives and palettes from gentle to tough. Heavy steel brushes are for hardware only.
Paint dries fastest in the one place you cannot see: the heel of the brush, where bristles disappear into the metal ferrule. Once acrylic, latex or gesso cures there, the bristles splay outward and the brush never quite holds its shape again. A wire tool can rescue many of these brushes, but only if you pick the right wire and use it in the right order.
This guide is a practical walk-through. It sets out a simple three-level cleaning kit, gives step-by-step methods for acrylic, oil, latex and gesso, and lists the tools that fit each step, with an honest note on which brushes should never meet a wire bristle.
The Three-Level Cleaning Kit
| Level | Tool | Use It For |
|---|---|---|
| 1. Gentle | Fingers, brush soap, nylon scrub brush | All artist brushes, ferrule exteriors, routine cleaning |
| 2. Bristle rescue | Painter’s brush comb (fine pins, brass bristles) | Wide flats, gesso and varnish brushes, hog bristle, mural brushes |
| 3. Hard surfaces | Brass, then stainless steel wire brushes | Palette knives, metal palettes, tube caps, easel hardware |
Always start at the gentlest level and move up only if needed. The aim is to remove paint without removing bristles, and most brushes never need to go beyond level two.

Why Paint Hardens at the Ferrule
When you dip a brush, capillary action draws paint up between the bristles toward the ferrule. Rinsing clears the tips easily, but the heel holds a reservoir of paint that dries slowly from the outside in. With acrylic and latex, that reservoir cures into a plastic plug that wedges the bristles apart. With oil, it thickens over several sessions into a gummy collar. Gesso adds fine mineral grit. Each needs softening before any comb can move it, which is why soaking comes before combing in every method below.
How We Chose
We picked these tools from the Amazon listing details checked in October 2026, considering bristle material, how each fits into a gentle-to-tough cleaning routine, whether it is designed for brushes or hard surfaces and how widely it is reviewed by Amazon buyers. The cleaning steps reflect established brush-care practice; we have not tested these specific tools.
Step-by-Step: Cleaning Brushes by Paint Type
Acrylic (wet or recently dry)
- Wipe excess paint onto a paper towel.
- Rinse in lukewarm water, working soap into the heel with your fingers.
- For wide brushes with paint at the heel, run a brush comb from the ferrule to the tip under running water.
- Rinse, reshape and dry flat.
For speed tips, see our guide on how to clean acrylic paint off brushes fast.
Acrylic (fully dried)
- Soak only the bristles in a brush restorer or rubbing alcohol for 30 minutes to a few hours.
- Massage softened paint toward the tip; use a comb on wide brushes.
- Wash with soap and water, reshape and dry.
Oil paint
- Wipe the brush thoroughly on a rag.
- Rinse in odorless mineral spirits, or work in a little safflower or linseed oil if you avoid solvents.
- Comb wide hog brushes gently to lift paint from the heel.
- Wash with brush soap, rinse, reshape and dry.
Our guides on cleaning oil paint brushes without odor and cleaning oil paint brushes without solvent explain both approaches in detail.
Latex and mural paint
- Clean while wet in warm soapy water.
- Comb wide synthetic brushes from heel to tip to remove trapped paint.
- Spin or shake out water and hang to dry.
Gesso
- Rinse immediately; gesso dries hard and gritty.
- Comb wide gesso brushes thoroughly, since particles lodge between bristles.
- Consider keeping dedicated, inexpensive brushes just for gesso.
Best Tools to Clean Paint Brushes Reviewed
1. ROLLINGDOG 4-in-1 Paint Brush Comb — Best for cleaning brushes and rollers
ROLLINGDOG makes this tool from 420 stainless steel that the listing says flexes without breaking and resists rust. One edge is a fine-tipped, long-toothed comb for separating bristles and removing paint deep in the brush head; the other edges are shaped to clean mini, large-diameter mini and standard paint rollers.
For artists who also use small foam or nap rollers for backgrounds, murals or printmaking-style textures, one tool handles both brushes and rollers.
Best suited for: mural painters and artists who use rollers as well as wide brushes.
Key features:
- 420 stainless steel
- Fine long-tooth brush comb
- Mini, large mini and standard roller cleaners
Pros:
- Four tools in one
- Rust resistant
- Long teeth reach deep into bristles
Cons and limitations:
- Steel teeth need a gentle hand on natural bristle
- Not for small artist brushes
Buying consideration: Use the comb with plenty of running water so loosened paint flushes away instead of re-depositing.
2. Wooster 1832/1831 Two-Sided Painters Brush Comb — Best for heavy buildup
Wooster’s comb pairs non-rusting brass bristles for heavy paint buildup with a 12-pin stainless comb that speeds washing and rinsing and reshapes the brush for storage.
Brass bristles are a step gentler than steel, so this is a good choice for natural bristle gesso and oil brushes as well as synthetic flats.
Best suited for: wide oil, gesso and varnish brushes.
Key features:
- Brass bristle side
- 12-pin stainless comb side
- Reshapes bristles before storage
Pros:
- Two levels of cleaning in one tool
- Gentler brass option
- Durable
Cons and limitations:
- Higher price than basic combs
- Too big for detail brushes
Buying consideration: Use the brass side first, then finish with the pin comb to straighten the bristles.
3. Purdy Paint Brush Comb — Best for basic combing
A compact Purdy wire comb for routine cleaning of wide brushes. The listing offers little detail, so treat it as a simple, no-frills tool from a well-known brush maker.
It is a good spare to keep next to the sink or in a mural kit.
Best suited for: routine cleanup of wide brushes.
Key features:
- Wire comb
- Compact size
Pros:
- Simple
- Inexpensive
Cons and limitations:
- Minimal listing information
Buying consideration: Store it dry so the wire stays clean.
4. IEGREMAR 3-Piece Nylon, Brass and Stainless Steel Brush Set — Best for a budget three-level set
IEGREMAR includes three small brushes: nylon, brass and stainless steel, with rubber-coated plastic handles and hanging holes. The listing suggests nylon for delicate items, brass for unfinished metal and steel for rust.
That maps neatly onto a painter’s needs: nylon for scrubbing the outside of ferrules and handles, brass for palette knives and metal palettes, and steel for crusted tube caps and easel hardware.
Best suited for: painters building a gentle-to-tough tool kit on a budget.
Key features:
- 3 brushes: nylon, brass, stainless
- Rubber-coated handles
- Hanging holes
Pros:
- Lowest price tier
- Three materials for three jobs
- Small heads reach tight spots
Cons and limitations:
- None designed for bristles
- Small heads are slow on large palettes
Buying consideration: Label the handles so you always reach for the gentlest brush first.
5. Lavaxon 3-Piece Wire Brush Set (7 in) — Best for comfortable three-material scrubbing
Lavaxon offers the same three bristle types, nylon, brass and stainless steel, on 7 inch brushes with slightly angled handles for a better grip.
The longer handles give more leverage than mini brushes, useful on glass palettes, sinks and metal trays caked with dried paint.
Best suited for: palettes, trays and sinks.
Key features:
- 3 brushes, 7 in
- Nylon, brass and stainless steel
- Angled plastic handles
Pros:
- Comfortable grip
- Covers gentle to tough jobs
- Portable
Cons and limitations:

Buying consideration: Use the nylon brush on glass palettes to avoid scratching.
6. Amazon Basics Stainless Mini Wire Brushes (3-pack) — Best for tight crevices on tools
Three mini brushes with 1/2 inch stainless heads and offset, solvent-resistant soft-grip handles. The small head reaches crevices, and the offset protects knuckles.
Great for the crank of a palette knife, the threads of tube caps and brush-washer coils.
Best suited for: cleaning studio tools and small hardware.
Key features:
- 1/2 in stainless heads
- Offset handle
- Solvent- and chemical-resistant
Pros:
- Reaches tight spots
- Low cost
Cons and limitations:

Buying consideration: Keep one in your solvent area and one by the acrylic sink.
7. MAXMAN 10 in Stainless Steel Wire Brushes (2-pack) — Best for heavy metal cleanup
Full-size stainless brushes with 4 x 16 rows of bristles and beech wood handles, built for rust, paint and scale. In a studio, they strip dried paint from metal easels, steel palettes and outdoor equipment.
They are the top level of the kit and the least often needed.
Best suited for: restoring metal equipment.
Key features:
- 10 in overall

Buying Guide: Choosing a Wire Brush to Clean Paint Brushes
Decide what you are cleaning
Bristles need a comb; ferrules and handles need nylon; tools and palettes need brass or steel.
Choose stainless or brass for rust resistance
Tools that sit near water should be stainless steel or brass.
Look at tooth length
Long, fine teeth (like the ROLLINGDOG comb) reach deeper into thick brushes.
Consider multi-use tools
Roller-cleaning edges or two-sided designs save space in a small studio.
Check grip comfort
Rubber or angled handles reduce hand fatigue when cleaning several brushes.
Rescue or Retire? Judging a Hardened Brush
Not every brush is worth the effort. Before reaching for a comb, check three things. First, the ferrule: if it is loose, cracked or rusted, the brush will keep shedding even after cleaning. Second, the bristle tips: if they are snapped off or melted (from heat or harsh solvents), cleaning will not bring back a point or edge. Third, the brush’s job: an inexpensive chip brush with cured gesso is often cheaper to replace than to rescue.
Brushes with a sound ferrule and intact tips, but with paint packed into the heel, usually respond well to a soak and gentle combing. Even if the shape is not perfect afterward, a rescued brush can be reassigned to dry brushing, stippling, texture or applying medium, so it still earns its place in the jar.
Preventing Paint Buildup at the Heel
- Load only the front half to two-thirds of the bristles; paint pushed into the heel is what hardens first.
- With acrylic, rinse every few minutes during long sessions, even if you plan to keep using the same color.
- Rest brushes flat in a shallow tray of water rather than standing them upright.
- Wash with soap at the end of every session, working lather right up to the ferrule with your fingertips.
- Comb wide brushes briefly during the final rinse so nothing sets overnight.
- Dry brushes flat or hanging bristles-down so water and diluted paint drain away from the ferrule.
Which Brushes Should Never Touch Wire
- Kolinsky sable and other natural-hair watercolor brushes
- Squirrel mops and soft wash brushes
- Small detail rounds, liners and spotters
- Soft synthetic watercolor brushes
Clean these with mild soap, lukewarm water and your fingers only.
Common Mistakes to Avoid
- Reaching for a steel brush before trying soap and a comb.
- Combing dried paint without softening it first.
- Working from tip to ferrule, which forces paint deeper.
- Using wire tools on soft watercolor brushes.
- Leaving brushes standing in water while you clean others.
- Forgetting to clean the cleaning tools, which spreads old paint.
- Using hot water, which can soften ferrule glue and loosen bristles while you comb.
- Combing a brush dry; always work with water, soap or solvent to lubricate the bristles.
FAQs
Should I use a wire brush to clean paint brushes?
Use a brush comb on wide brushes. General wire scratch brushes are for tools and hard surfaces, not bristles.
What is the best tool to clean dried paint from a brush?
Soften the paint with a brush restorer or solvent, then use a brush comb on wide brushes or your fingers on small ones.
Can a brush comb fix splayed bristles?
It can remove the paint causing splaying and straighten bristles. Reshape and dry the brush flat afterward.
What are nylon, brass and steel wire brushes for?
Nylon is gentlest for delicate surfaces, brass is medium for soft metals and steel is toughest for rust and heavy residue.
How do I clean a roller and brush together?
A multi-tool like the ROLLINGDOG 4-in-1 has a brush comb and roller-cleaning edges.
Can I use rubbing alcohol on dried acrylic in brushes?
Many painters soak synthetic brushes in isopropyl alcohol to soften dried acrylic. Limit soaking to the bristles, then wash thoroughly with soap and water. Avoid long soaks for natural hair.
Is it worth saving an old brush with dried paint?
Often, yes. Even if it does not return to perfect shape, a rescued brush is useful for texture, dry brush and gesso.
Final Recommendation
Build a small kit. For bristles, choose the ROLLINGDOG 4-in-1 comb if you also clean rollers, or the Wooster two-sided comb for its gentler brass side. Keep a Purdy comb as a spare. Add the IEGREMAR or Lavaxon three-material sets for ferrules, palette knives and palettes, the Amazon Basics mini brushes for crevices and the MAXMAN steel brushes for heavy metal cleanup. Work from gentle to tough, and keep wire away from soft artist brushes.
