Choose a cleaner by paint and airbrush compatibility
The best airbrush cleaner for your bench is the one the manufacturer says is for the paint you sprayed and that your airbrush manual permits. Two documented options show how the choice works:
- Medea Airbrush Cleaner — Iwata lists it as a ready-to-use, general-purpose airbrush cleaner, and Iwata's paint guide recommends it for water-soluble paints.
- Tamiya Airbrush Cleaner, item 87089 — Tamiya describes this 250 mL product as a cleaner for stubborn paint stains on airbrushes and other painting equipment.
Neither label makes either product a universal cleaner. Before you buy or use one, check the paint label for the actual chemistry (water-soluble, lacquer, or enamel) and check the airbrush manual for the cleaners and solvents it allows. If the paint has already dried, the method may matter more than the bottle.
Medea Airbrush Cleaner: documented for water-soluble paints
Iwata lists Medea Airbrush Cleaner as a ready-to-use general-purpose airbrush cleaner. The manufacturer's airbrush paint guide is more specific: it recommends Medea for water-soluble paints and tells users of other materials to follow the paint label or the material manufacturer's guidance.
That makes Medea a reasonable starting point when you are spraying a water-soluble acrylic and want one bottle for routine flushing. It does not prove the cleaner will remove every cured paint, and it is not an independent comparison against other brands. If your acrylic is not labeled water-soluble, the paint label—not the word acrylic—decides what to use.
Tamiya Airbrush Cleaner 87089: documented for stubborn stains
Tamiya identifies Airbrush Cleaner item 87089 as a 250 mL cleaning liquid for stubborn paint stains on airbrushes and other painting equipment, including metal palettes and mixers. That is the manufacturer's stated role; the page does not establish compatibility with every paint brand, seal, finish, or cured lacquer.
Treat it as a targeted cleaner for residue that a normal flush has not removed, not as proof that a stronger product is always better. Check the paint label and the airbrush manual before it touches seals, O-rings, plated parts, or a finish you care about. If the manual does not list the cleaner or its solvent, do not soak the brush in it.
The three checks that decide the purchase
- Paint label: Does it say water-soluble, lacquer, or enamel? Does it name a thinner or cleaner family?
- Airbrush manual: Which cleaners and solvents are allowed, and which parts can be soaked or removed?
- Residue state: Is the paint still wet, or has it dried? A wet flush and a dried-paint soak are different jobs.
If those three answers do not line up, no product name settles it. Ask the paint manufacturer or the airbrush maker rather than guessing. The manufacturer details above were checked on October 20, 2026.
Match the cleaner to the paint family
Model paint is not one chemistry. Lacquer, enamel, and acrylic behave differently, and the cleaner has to match the paint that is actually in the cup. The model paint types guide explains the families; the practical cleaning split is below.
What you sprayed | Documented starting point | Check before use |
|---|---|---|
Water-soluble acrylic, still wet | Water or a water-based airbrush cleaner | Paint label says water-soluble; manual allows water or cleaner |
Water-soluble acrylic, dried | Water-based cleaner with dwell time | Manual's soaking limits; water alone may not break the film |
Lacquer | Cleaner or thinner from the same lacquer family | Manual allows the solvent; ventilation and containment |
Enamel | Enamel thinner or a cleaner labeled for enamel | Manual allows the solvent; adequate dwell time |
Mixed session | Clean after the last paint, then deep clean before switching families | Residue from the previous family is fully gone |
Stubborn stains on equipment | Tamiya 87089, where the label and manual allow | Brand, seal, finish, and cured-lacquer compatibility |
A table can only give categories. The product label and manual still control the specific choice.
Water-soluble acrylic paint: water while wet, cleaner when dried
For water-soluble acrylic, plain water is enough for a quick rinse between colors while the paint is still wet. It is not a universal acrylic cleaner. Some model acrylics are not water-soluble, and water alone is not a reliable way to break a dried film.
Once the paint has dried, give a water-based cleaner time to work: add cleaner, let it dwell according to the product label, then flush and repeat. Do not jump to a solvent before trying the water-based route; a solvent is not automatically better for acrylic residue and may be harsher on the brush. For thinning and flow problems, see the airbrush thinning guide and flow improver vs thinner; cleaning is a separate job from thinning.
Medea is the documented water-soluble option in this article. Check that your paint label actually says water-soluble before relying on it.
Lacquer paint: use the thinner family your manual allows
Lacquer residue can set before you finish the session, so the flush right after spraying is much easier than the cleanup after it sits. Use a cleaner or thinner from the same lacquer family the paint label names, and confirm the airbrush manual permits that solvent. The airbrush thinner guide explains how the families differ.
Do not spray solvent-based cleaner into open air. Flush according to the product label and manual, work in a ventilated area, and capture waste in a container intended for it if the manual allows. Wipe the needle and nozzle, and check the pattern on scrap. A solvent that is fine for the paint can still be wrong for seals, O-rings, or plated parts, so check the manual before soaking anything.
Enamel paint: match the thinner and allow dwell time
For enamel, use enamel thinner or a cleaner explicitly labeled for enamel paints. Enamel residue can stay workable longer on the surface but still cures tough, so an immediate flush is easier than a cleanup after it has sat. Use the thinner that matches the paint you sprayed; if you want a final clean before storage, use a product labeled for that job.
The same compatibility rule applies: the paint label names the chemistry, and the airbrush manual says whether the brush can take it.
Commercial cleaner or the paint's own thinner?
A commercial cleaner is blended to be used as a cleaner. A paint's own thinner is blended to thin that paint. Those jobs overlap when the chemistry matches, but they are not automatically interchangeable.
A thinner from the same family can be a practical flush for fresh residue if the paint label and airbrush manual allow it. Do not assume it is a final cleaner, a dried-paint remover, or safe for every seal. A dedicated cleaner may contain different additives and may be the better choice for a final pass or storage. If you are unsure, follow the paint label and the airbrush manual rather than substituting one for the other.
Do not mix two cleaners in the same cup hoping for a stronger result. Pick one, finish the clean, and try the other only if the residue survives and the manual allows it.
A flush routine that works with either product
The routine matters as much as the bottle. Flush before the paint dries, and use the cleaner the label and manual support.
- Dump the leftover paint from the cup or bottle before adding anything.
- Rinse the cup with a little cleaner and dump it, so you are not pushing a full cup of paint into the brush.
- Flush the fluid path as the airbrush manual directs. For water-based products, short bursts into a spray-out container are typical; for solvent-based products, follow the label's ventilation and containment instructions and do not atomize the solvent into the room.
- Wipe the tip and needle, and remove the needle only if the manual allows it.
- Reassemble, then check the pattern on scrap paper.
A clear mist is a useful checkpoint: it shows the fluid path is flowing. It is not proof that the nozzle, needle, and inner passages are free of residue. Also look for an even pattern with no spatter, color tint, or bubbling. If the pattern is still patchy, residue is one possibility; paint flow/viscosity, air supply, and worn or incorrectly assembled parts can also affect the pattern; Iwata's frequently asked questions cover these other causes. Work through the airbrush troubleshooting diagnostic before assuming the cleaner is at fault; the airbrush not spraying paint checklist covers the common fluid-path causes.
A deep clean is not automatically required just because the brush has sat unused or you are switching paint families. Decide by remaining residue, poor flow or spray after a normal flush, and the maintenance instructions for your model; Iwata's airbrush cleaning guidance is one documented example. Between colors in one family, a thorough flush is usually enough.
Common mistakes that waste cleaner
- Letting paint dry before the first flush, which turns a rinse into a soak.
- Using water alone on dried acrylic, lacquer, or enamel and expecting it to break the film.
- Assuming every acrylic is water-soluble; the paint label decides.
- Reaching for a strong solvent on fresh water-soluble acrylic that a water-based cleaner would lift.
- Soaking the whole airbrush without checking whether the plating, seals, and finish tolerate it.
- Cleaning the cup and calling it done while the nozzle and needle keep old residue.
- Mixing cleaners in the same cup.
- Treating a clear mist as proof of a clean brush.
FAQ
Can I clean an airbrush with water alone?
Only for paint labeled water-soluble, and only while it is still wet. Water alone is not a reliable cleaner for dried water-soluble acrylic; use a water-based cleaner with dwell time. Lacquers and enamels need a cleaner or thinner from their own family, and the manual must allow it.
Is household glass cleaner safe as an airbrush cleaner?
Only if the airbrush manual specifically allows it. Glass cleaners are formulated for glass and surfaces, and some contain ammonia or additives an airbrush is not designed for. Do not use one as a substitute for a product labeled for airbrush cleaning.
Can I use paint thinner instead of airbrush cleaner?
Sometimes, for fresh residue from the same paint family, if the paint label and airbrush manual allow it. Thinner is formulated to thin paint, not necessarily to remove dried residue or protect seals. Do not treat it as an automatic substitute, especially for a final clean or a dried film.
Do I need a cleaning station or spray-out pot?
No. It is a convenience that captures waste and reduces mess, not a required tool. Whether you use one depends on your workspace and the cleaner's instructions. It does not replace cleaning the nozzle and needle.
Is ultrasonic cleaning safe for an airbrush?
It depends on the airbrush. Plating, seals, and finishes vary, and the solvent or heat used in a bath may not suit every model. Follow the manufacturer's cleaning instructions before putting parts in a bath, and do not immerse the whole brush.
How often should I do a deep clean?
A period of disuse or a switch of paint families is not a universal trigger. Decide by remaining residue, poor flow or spray, and the maintenance instructions for your model; Iwata's airbrush cleaning guidance is one documented example. Between colors within one family, a thorough flush is usually enough; a full teardown after every session is optional unless the manual says otherwise.
The bottom line
There is no single best airbrush cleaner for every paint and brush. For water-soluble acrylics, Iwata documents Medea as a ready-to-use general-purpose cleaner. For stubborn paint stains on an airbrush or other painting equipment, Tamiya documents item 87089 as a 250 mL cleaner. For lacquers and enamels, stay with the thinner or cleaner family named on the paint label and allowed by the airbrush manual.
The decision is paint label first, airbrush manual second, wet-or-dried third. Flush before the paint sets, use a clear mist as a checkpoint rather than proof, and check the nozzle and needle before buying a stronger product.
