Open shelves look fantastic — right up until a grey film settles into every recess and flattens the contrast you worked so hard for. Dust is the slow killer of a painted collection. The good news: cleaning it off is easy and safe with the right method, and genuinely risky without it. Here's how to get dust off painted miniatures without lifting paint, snapping spears, or leaving water marks.
Start with the gentlest method that works
Most dust comes off with airflow and a soft brush. Reach for harsher methods only when those fail.
- Soft, dry brush. A large, soft makeup brush or a dedicated soft modelling brush lifts surface dust from flat panels and raised detail. Brush gently, top to bottom. This alone handles most display dust if you do it every few weeks.
- Air. A puff of air clears dust from deep recesses a brush can't reach. Use a hand blower bulb (the type sold for camera lenses) for control. Canned air works too, but keep it upright, hold it 15–20cm away, and use short bursts — held too close or tipped, it can spit cold propellant and frost the paint.
- The wet method (for stubborn, baked-on dust). If models have sat untouched for months, dust binds with airborne grease and a dry brush won't shift it. Dip in lukewarm water with a single drop of washing-up liquid, swirl gently or use a soft brush, rinse in clean water, and leave to air-dry fully before handling. Only do this on models with a sealed varnish coat — bare acrylic or unsealed pigments can lift.
What not to do
- No compressed air up close. Frosting and propellant spit ruin a finish instantly.
- No vacuum directly on the model. Thin spears, antennae and banners disappear in a heartbeat. If you vacuum, cover the nozzle with a cloth or stocking and hold it nearby, never against the model.
- No furniture polish or household sprays. They leave residue, react with varnish, and attract more dust.
- Don't scrub. Dust is abrasive — pressure grinds it into the paint and burnishes edges.
Stop dusting so often: reduce dust at the source
Cleaning is the cure; the fix is displaying smart so dust lands less in the first place:
- Keep models off the floor and away from doorways and radiators, where airborne dust circulates most.
- A light coat of varnish gives a tougher, easier-to-clean surface — see should you varnish painted miniatures.
- Mind where the cabinet lives in the first place: heat, damp and UV do more long-term harm than dust — see where not to store miniatures.

A quick word on display
However you clean them, models look their best raised and angled rather than flat in a row. A tiered modular stand lifts back ranks into view, gets air around each figure so dust settles less, and makes the occasional brush-down a two-minute job rather than an afternoon. Our WarSplay modular display stands are built for exactly that, support 25–100mm bases, and are compatible with Warhammer 40k and other popular tabletop systems. For the full setup, see how to display wargamer miniatures.
Frequently asked questions
What's the safest way to clean dust off painted miniatures?
A soft makeup brush plus a hand-pump air blower handles almost everything. Save the wet method for sealed models with baked-on grime, and skip canned air up close.
Can I wash painted miniatures in water?
Yes, if they're varnished — lukewarm water, a drop of washing-up liquid, gentle swirl, rinse, and full air-dry. Unsealed paint can lift, so varnish first.
How often should I dust my display?
A two-minute brush-down every couple of weeks beats a risky deep-clean twice a year. Little and often keeps the paint crisp.
