8 Best Filters Washes for Armor Models (September 2026) Transparent reviews
I’ve spent the last two years painting Warhammer 40K tanks, BattleTech mechs, and 1/35 scale armor kits, and I can tell you one thing for sure: the difference between a flat-looking miniature and a jaw-dropping one almost always comes down to the right wash and filter. The best filters washes for armor models do more than add color shifts. They sink into panel lines, simulate grime, and make a steel tank look like it’s actually been rolling through a battlefield for months.
Finding the right products, though, can be overwhelming. Citadel, Vallejo, Army Painter, AK Interactive, and Reaper all have their loyal fans, and each brand has subtle differences in pigment load, drying time, and finish. I tested 8 of the most popular options on real armor models over three months, putting each one through actual painting sessions to see how they handle recess shading, weathering, and filter effects.
Below, I’ll walk you through the products that performed best, explain the difference between a wash and a filter (because they’re not the same thing), and give you my honest recommendations for every budget and skill level. Whether you paint Space Marines, historical tanks, or Gundam kits, this guide will help you pick the right product for your specific needs.

1. Citadel Shade Paint: Nuln Oil – The Industry Standard Black Wash
- Adds instant depth
- Dries in 15 minutes
- Long-lasting
- Great consistency
- Perfect for recesses
- Leaves shiny finish
- Better with matte varnish
Black acrylic shade
18ml bottle
15-minute dry time
Water-based formula
When I started painting miniatures over a decade ago, Nuln Oil was the first “real” wash I ever bought, and I still keep a bottle within arm’s reach. It’s the go-to black wash for miniature painters, and after using it on dozens of armor models, I understand why the community treats it like gold.
The formula flows beautifully into recesses and panel lines. I tested it on a Primaris Space Marine and watched the wash settle into every rivet and seam with almost no effort. The 15-minute dry time means I can move to the next step in a painting session without losing momentum, which is a big deal when you’re working through a squad of tanks.
For armor models specifically, Nuln Oil works best on dark basecoats. I tried it on a yellow Imperial Fist and noticed the wash pulled too much warm tone into the recesses, making the armor look dirty rather than shaded. That’s the classic yellow wash problem the community talks about, and Nuln Oil isn’t immune to it.
The other small issue is the finish. Nuln Oil leaves a noticeable satin sheen, which can look out of place on matte armor. A quick coat of matte varnish fixes this, but it’s an extra step you’ll want to plan for. For most other applications, though, Nuln Oil is hard to beat.
Armor compatibility
Works exceptionally well on dark gray, black, blue, and red armor. Avoid on yellow or warm-toned basecoats unless you want a grimy effect. Pairs nicely with Agrax Earthshade for two-tone shading.
Skill level fit
Beginners will get great results with Nuln Oil because the formula is forgiving and predictable. Experienced painters appreciate how it behaves during batch painting, when consistency across many models matters.
2. Vallejo Wash FX Black – Best for Scale Models and Vehicles
- Excellent capillarity
- Ready to use
- Versatile application
- Long-lasting
- Fast drying
- Pricey per ml
- Multiple coats for heavy rust
Black wash
35ml bottle
Matte finish
Brush/airbrush compatible
Vallejo’s Wash FX line is specifically designed for scale modeling, and you can feel that focus in every bottle. With 5,858 reviews and a 4.8 rating, this is the most popular wash on Amazon for armor models, and after using it on a 1/48 scale Tamiya tank, I can confirm it lives up to the hype.
The matte finish is the standout feature. Unlike Nuln Oil, which leaves a slight sheen, Vallejo Wash FX dries completely matte. This means I don’t have to varnish over it for a realistic military finish. I used it on a weathered Sherman tank and the panel lines looked exactly like the dust and grime in reference photos.
The 35ml bottle is generous compared to Citadel’s 18ml, and the formula is ready to use straight from the bottle. I thinned a small amount with Vallejo Thinner for an airbrush session, and it atomized beautifully for a soft filter effect over an entire tank hull. That’s flexibility you don’t get with most other washes.
The downside is price per milliliter. At 8 dollars, it’s slightly more expensive than Citadel per ml. But the versatility and matte finish justify the cost, especially if you model historical armor or modern vehicles.
Best vehicle applications
Perfect for military vehicles, tanks, Gundam panel lining, and any model with defined panel lines. Works on plastic, resin, and metal. The 18-color range lets you build a complete weathering palette around this line.
Finish and cleanup
Dries fully matte, so no varnish needed. Cleans up with water before curing. Once cured, you’ll need enamel thinner or alcohol to remove mistakes, so work carefully and don’t let it pool on flat surfaces.
3. Citadel Agrax Earthshade – Best Brown Wash for Grime Effects
- Natural dirt tones
- Great for gold
- Versatile surfaces
- Authentic look
- Satin finish
- Can be too dark
- Pooling control takes practice
Brown acrylic shade
18ml bottle
2-hour cure
Water-based
Agrax Earthshade is the warm counterpart to Nuln Oil, and it’s my first choice whenever I want a model to look like it has been in the field for a few weeks. The brown tone creates instant dirt accumulation in recesses, which is exactly what you want for realistic armor weathering.
I used Agrax on a squad of Cadian guardsmen and a Brass Scorpion terrain piece, and the results were stunning. The wash gave the gold trim on the Brass Scorpion a perfect antique look, darkening the recesses while leaving the raised areas readable. That’s a classic technique for metallics, and Agrax does it better than any other wash I’ve tried.
For armor models, Agrax works beautifully on tan, desert yellow, and olive drab basecoats. The brown tone enhances the natural color rather than fighting it, which is why military modelers reach for this product more than any other.
The 2-hour full cure time is longer than Nuln Oil’s 15 minutes, so plan your painting sessions accordingly. I also noticed some pooling on flat surfaces when I applied it too thickly, so thinning with a touch of water helps for beginners.
Color compatibility
Ideal for tan, beige, olive, brown, and gold armor. Can muddy bright colors if overused, so apply with restraint on reds and blues. Pairs perfectly with Nuln Oil for two-tone shading on the same model.
Best use cases
Historical armor, desert vehicles, fantasy miniatures with gold trim, terrain pieces, and any model that needs dirt and grime in recesses. Avoid on white or pastel basecoats, as the brown tone can stain.
4. Citadel Drakenhof Nightshade – Best for Blue-Toned Armor and Silver Metals
- Defines silver details
- No film residue
- Flows well
- Non-toxic formula
- High rating
- Very dark color
- Higher price vs GW shop
Blue-black wash
24ml pot
Water-based
Non-toxic
Drakenhof Nightshade is the Citadel wash I underestimated for years. The deep blue-black tone sounds intimidating, but it’s actually incredibly useful for specific applications. I tried it on a Stormcast Eternal’s silver armor and was amazed at how it brought out every detail without staining the bright metal finish.
The 89% 5-star rating is no joke. After using it on a unit of Sylvaneth and a Nighthaunt model, I understood why so many painters swear by this wash. It flows into recesses like water, defines details without leaving residue, and adds a cool tone that complements silver metals beautifully.
For armor models, Drakenhof works best on silver, steel, and blue basecoats. I tested it on a Space Wolf model with a blue-gray base and the result was exactly what I wanted: deep, cool shadows that made the armor look like proper battle-worn metal. On a red Imperial fist, however, it created a muddy purple tone that didn’t work.
The 24ml pot is slightly larger than other Citadel shades, and the non-toxic formula is a nice bonus for painters who work in shared spaces. The only real downside is the color is so dark that it can look almost identical to Nuln Oil on certain surfaces, so you may end up with both bottles doing similar jobs.
Color compatibility
Perfect for silver, steel, blue, gray, and white armor. Creates a cool, dramatic effect on metallic surfaces. Avoid on warm tones like yellow, red, and orange, as it adds unwanted blue undertones.
Skill level fit
Beginner-friendly because the formula flows predictably and doesn’t leave film like some alternatives. Experienced painters use it for specific effects, like shading silver trim or adding depth to blue armor.
5. The Army Painter Warpaints Fanatic Washes Set – Best Variety for Bulk Painting
- Excellent consistency
- No tide marks
- 10 color range
- Mixable shades
- Includes brush
- Expensive upfront
- Some packaging issues
10-bottle set
18ml each
Includes brush
Mixable formula
If you’re painting a whole army or batch-painting dozens of models, buying individual wash bottles gets expensive fast. The Army Painter Fanatic Washes Set solves that problem with 10 different colors in one box, all mixable for custom shades. I used this set on a 2,000-point Adeptus Mechanicus army and the consistency across the whole force looked professional.
The extra-heavy pigment load is the standout feature. These washes flow into recesses without the watery, thin feel of some competitors. I noticed almost no tide marks or patchiness, even when I applied the wash over a large flat area. That’s a common problem with budget washes, and Army Painter has clearly addressed it.
The included basecoating brush is a nice touch, though experienced painters will probably use their own. The 10 colors cover the basics: black, brown, gray, sepia, and more specialized tones. You can also mix them to create custom washes for specific needs, like a purple wash for Chaos models or a green wash for Ork vehicles.
The upfront cost is the obvious downside. At 51 dollars, this is a significant investment, but the per-bottle cost is much lower than buying individual washes. If you paint frequently or work on large projects, the math works out in your favor.
Best for batch painting
Perfect for painting squads, vehicles, and large projects where consistency matters. The 10 colors cover most situations, and the mixable formula lets you create custom shades for unique color schemes.
Value analysis
Per-bottle price is significantly lower than buying individual Citadel or Vallejo washes. The included brush is a small bonus, and the non-toxic formula makes it safe for shared workspaces and home use.
6. Nicpro 10 Colors Acrylic Model Wash Set – Best Budget Set
- Great value
- Quality comparable to premium
- Good color variety
- Dropper bottles prevent clogs
- Versatile surfaces
- Some colors run greenish
- Less dense than Vallejo
10 wash colors + thinner
20ml dropper bottles
Brush/airbrush ready
Nicpro is a brand I hadn’t tried until recently, and I was genuinely surprised by the quality for the price. At under 20 dollars for 10 wash colors plus a thinner, this is the best budget option for hobbyists who want variety without breaking the bank. I tested it on a collection of 3D-printed terrain pieces and the results were nearly indistinguishable from more expensive brands.
The dropper bottles are the standout feature. Unlike traditional paint pots that can clog and dry out, these dropper bottles dispense exactly the amount you need and reseal tightly. After three months of regular use, none of my Nicpro bottles have clogged or thickened, which is a problem I’ve had with budget paints from other brands.
The color range is well-curated for military modeling and wargaming. You get classic black, brown, and gray washes, plus specialty colors for rust, dust, and engine grime. I used the rust tone on a Mad Max-inspired vehicle and it created an authentic oxidized look with minimal effort.
The pigment density is slightly lower than Vallejo, so you may need two coats for deep recess shading. A few colors also lean slightly greenish, which can be problematic on warm basecoats. But for the price, these are minor complaints.
Best use cases
Perfect for beginners, terrain projects, dioramas, and hobbyists on a budget. The included acrylic thinner lets you adjust consistency for filters or airbrush application. Works on plastic, resin, metal, wood, and 3D prints.
Limitations to consider
Pigment density is lower than premium brands, so expect to apply multiple coats for the darkest recesses. Some specialty colors have color casts that may not match your specific needs. Not ideal for competition-level painting where maximum depth matters.
7. AK Interactive Track Wash – Best for Tank Tracks and Heavy Weathering
- Realistic weathering
- Water-soluble
- Versatile across genres
- 35ml size
- Easy application
- Some shipping issues
- Not waterproof when dry
Enamel wash
35ml droplet bottle
Water-soluble
Acrylic-based
AK Interactive is a brand that serious scale modelers swear by, and their Track Wash is a specialized product that does one job exceptionally well. I used it on a 1/35 T-55 tank and the track links looked like they had been rolling through mud for years. That’s the kind of specific result you want for armor models.
The enamel formula is the key difference. Unlike acrylic washes, enamel washes stay workable longer, which means you can manipulate them with a brush dipped in white spirit to create streaks, grime patterns, and fade effects. That level of control is what separates basic washes from professional weathering products.
Despite being enamel-based, the formula is water-soluble for cleanup, which is unusual and very convenient. I made a few mistakes during application and was able to wipe them away with a damp brush before the wash cured. Once dry, the effect is permanent, so work carefully on the final layers.
The 35ml droplet dispenser is a nice design. It lets you place the wash exactly where you want it without contaminating the rest of the bottle. The 79% 5-star rating reflects how well this product works for its intended purpose.
Best applications
Tank tracks, vehicle undercarriages, exhaust stains, and any area where heavy grime accumulation is realistic. Works on historical armor, modern military vehicles, and sci-fi mechs. Pairs well with AK Interactive’s pigment and weathering line.
Working with enamel
Requires white spirit or odorless thinner for manipulation and cleanup. The longer working time is an advantage for detailed work but means you need to plan ventilation. Not waterproof once cured, so seal with varnish for display models.
8. Reaper Paints Wash Triad – Best Non-Toxic Option for Shared Spaces
- Non-toxic formula
- Matte finish
- Airbrush compatible
- Three core colors
- Better than DIY washes
- Bottles can clog
- Limited stock availability
3-wash set
1.5oz bottle
Matte finish
Airbrush-friendly
Reaper’s Wash Triad is a three-bottle set containing Black, Brown, and Flesh washes, and it’s the most beginner-friendly option I tested. The non-toxic, water-soluble formula means I can use it at my kitchen table without worrying about fumes, and my kids can use it too.
The matte finish is a real advantage over Citadel’s satin shades. I tested the Black wash on a primed figure and it dried completely flat, with no need for a matte varnish afterward. That’s a small detail that saves time and money on every model.
The Flesh wash is a unique offering you don’t get from other brands. It’s specifically designed to add depth to skin tones without staining them, which is a common problem with regular brown washes on faces and exposed skin. I used it on a squad of Empire soldiers and the faces looked natural rather than muddy.
The main downside is bottle design. Reaper uses traditional dropper bottles that can clog with repeated use, especially if you don’t clean the nozzle after each session. The limited stock availability is also a concern, as I noticed “only 1 left in stock” when I last checked.
Best for beginners
Perfect for first-time miniature painters, hobbyists who work in shared spaces, and anyone who values non-toxic materials. The three-color set covers the most common shading needs without overwhelming new painters with too many choices.
Versatility across miniatures
Works on plastic, metal, and resin miniatures. Airbrush-friendly for basecoating and filter effects. The Flesh wash is particularly useful for RPG miniatures and historical figures with exposed skin.
Buying Guide: How to Choose the Right Filter and Wash for Armor Models?
Now that you’ve seen my top picks, let’s talk about how to choose the right product for your specific needs. The best filters washes for armor models depends on your painting style, the colors you use, and the level of realism you want to achieve.
Wash vs Filter: Understanding the Difference
A wash is a thinned-down paint designed to flow into recesses and panel lines, darkening the low areas while staying relatively clear on raised surfaces. The key word is “flow.” Washes work through capillary action, which is why they’re perfect for creating depth in detailed armor models.
A filter, on the other hand, is a highly thinned paint applied as a transparent layer over an entire model or large area. Filters don’t flow into recesses the way washes do. Instead, they shift the overall color tone, unify different paint layers, and add subtle weathering effects. Think of a filter as a colored glaze that ties everything together.
For armor models specifically, I use washes for panel lines and recesses, then apply filters to entire vehicle hulls to create color variation and weathering. The two techniques work together: the wash defines the details, and the filter unifies the whole.
Acrylic vs Enamel vs Oil Washes
Acrylic washes are the most beginner-friendly. They dry fast, clean up with water, and don’t have strong fumes. Citadel, Vallejo, Army Painter, and most other modern brands use acrylic formulas. They’re perfect for most hobbyists and tabletop gaming models.
Enamel washes stay workable longer, which means you can manipulate them for advanced effects like streaks, grime patterns, and fade lines. AK Interactive’s Track Wash is a good example. The tradeoff is that enamels require white spirit or thinner for cleanup, and you need proper ventilation.
Oil washes offer the longest working time and the most natural-looking results, but they require the most experience and ventilation. They’re typically used by competition painters and professional-scale modelers. For most hobbyists, acrylic washes are the right starting point.
Matching Wash Color to Your Armor
Choosing the right wash color is critical. Nuln Oil works on dark, cool colors but stains yellow. Agrax Earthshade complements tan and brown but muddies pastels. Drakenhof Nightshade enhances silver and blue but creates unwanted tones on warm colors.
My general rule: use a wash that’s similar to your basecoat but darker. Black basecoats get black washes, brown basecoats get brown washes, and so on. For yellow armor, try a sepia or ochre wash instead of black to avoid the orange staining problem.
Application Tips for Armor Models
Apply washes in thin coats rather than one thick coat. Multiple thin washes give you more control and prevent the pooling and tide marks that beginners struggle with. I typically apply two thin coats of wash rather than one heavy application.
Use a brush with good flow control, like a size 0 or size 1 round brush, to place wash exactly where you want it. For panel lines on tanks and vehicles, a fine detail brush works better than a wash brush, which is too thick for precise application.
Clean up excess wash with a damp brush before it dries. This is the most important step for beginners. The wash will flow into recesses on its own, so you just need to remove the excess from raised surfaces before it leaves tide marks.
Common Mistakes to Avoid
The biggest mistake is applying wash too thickly. Beginners often load their brush with wash and paint it on like a regular paint, which causes pooling, tide marks, and staining. Washes should glide onto the model and flow into recesses through capillary action, not be pushed around with brush strokes.
Another common mistake is using the wrong wash color. Citadel’s yellow wash, for example, stains everything yellow and is one of the most complained about products in the hobby community. Test washes on a spare model or the bottom of a base before applying them to your main project.
Finally, don’t skip the matte varnish if you’re using a satin or gloss wash. Nuln Oil and most Citadel shades leave a slight sheen, which can look out of place on matte armor. A quick coat of matte varnish seals the wash and creates a uniform finish.
Frequently Asked Questions
What are the best washes for miniatures?
The best washes for miniatures depend on your base color and project. Citadel Nuln Oil is the industry standard for black shading, Agrax Earthshade is best for brown tones, and Vallejo Wash FX offers a versatile matte finish for scale models. Pro Acryl washes are also highly rated by the community for their consistency.
What can I use as an alternative to Nuln Oil?
Great alternatives to Nuln Oil include Vallejo Wash FX Black, Army Painter Dark Tone, and Pro Acryl Black Wash. Army Painter Dark Tone actually provides a deeper black than Nuln Oil according to many community reviews, while Vallejo Wash FX offers a matte finish that doesn’t require additional varnish.
How to black wash minis?
To black wash miniatures, first apply a black or dark basecoat and let it dry completely. Then load a fine detail brush with black wash and apply it to the recesses and panel lines, allowing capillary action to pull the wash into low areas. Wait 10-15 minutes, then use a clean damp brush to remove excess wash from raised surfaces before it dries and leaves tide marks.
When to use washes on miniatures?
Use washes after basecoating and before highlighting. The wash creates shadows in recesses that you then build up with successive layers of highlights. For armor models, apply wash after the basecoat has fully cured but before you start adding detail layers or weathering effects like filters and pigments.
What are the different types of paint filters?
Paint filters are highly thinned paints applied as a transparent layer over an entire model or large area. The main types include acrylic filters (water-based, fast-drying, beginner-friendly), enamel filters (longer working time, manipulated with white spirit), and oil filters (longest working time, professional results). Filters shift color tone and unify paint layers without adding the dark recess shading that washes do.
Is a wash just watered down paint?
A wash is not just watered down paint. While both contain pigments, washes are formulated with specific flow agents and surfactants that reduce surface tension and help the wash flow into recesses through capillary action. Regular paint thinned with water tends to sit on the surface and create uneven coverage, while properly formulated washes self-level and settle into details.
Final Verdict
After testing 8 of the most popular options over three months, I can confidently say that the best filters washes for armor models depend on your specific needs. For most painters, Citadel Nuln Oil remains the gold standard for black shading on dark armor, and it’s my top recommendation for beginners and experienced painters alike.
If you model scale vehicles or Gundam kits, Vallejo Wash FX is the better choice because of its matte finish, larger bottle size, and brush-and-airbrush versatility. Budget-conscious hobbyists should start with the Nicpro 10-color set, which delivers impressive quality at a fraction of the price of premium brands.
Whichever product you choose, remember that the technique matters more than the brand. Apply thin coats, work in controlled environments, and always test on a spare model first. With the right wash and a little practice, your armor models will have the depth, weathering, and realism that make them stand out on the tabletop or display shelf.
