How to strip paint from a miniature
A secondhand model, an old project you want to redo, a paint job gone badly wrong — stripping gets you back to bare plastic or resin. The two real methods, and the material test that saves a resin model from damage.
No card needed for your first render.
Stripping paint from a miniature means soaking it in a solvent — usually isopropyl alcohol or a dedicated paint-stripping solution — until the old paint softens and can be scrubbed off with a toothbrush, returning the model to bare plastic, resin or metal ready for a fresh coat of primer.
Test your material first
This is the step that gets skipped and causes real damage. Isopropyl alcohol is safe on most hard plastic miniatures, but stripping solutions — and even alcohol on some soft PVC or certain resins — can warp, soften or melt the wrong material. Before soaking a whole model, dunk one small, hidden part (a base tab, an unused bit from the sprue) for the same amount of time you plan to soak the model. If it holds up, proceed. If it goes soft or tacky, stop and use a milder method.
Isopropyl alcohol soak
The most common beginner-recommended method: cheap, widely available, and gentle enough for most hard-plastic miniatures. Submerge the model fully in isopropyl alcohol (90%+ concentration works faster than lower grades) in a sealed, ventilated container. Soak time varies with paint thickness and how many layers are on the model — check progress periodically rather than assuming a fixed time.
Dedicated stripping solutions
Purpose-made stripping products work faster and cut through heavier or older paint more reliably than alcohol alone, but they're also harsher — this is exactly where the material test above matters most. Follow the product's own soak-time guidance rather than guessing, and always work in a ventilated space.
The process, step by step
-
Test a hidden spot first
Confirm the material holds up before committing the whole model — this is the step that prevents real damage.
-
Soak fully submerged, sealed and ventilated
Patience matters more than force here. Check periodically rather than assuming a fixed soak time.
-
Scrub gently with an old toothbrush
Work in the recesses where paint tends to hold on longest. A second short soak clears stubborn spots rather than aggressive scrubbing.
-
Rinse and dry fully before re-priming
Any leftover solvent or moisture under a fresh coat of primer can cause exactly the frosted, grainy texture covered in fixing paint mistakes. Let it dry completely, then head to choosing a primer for the restart.
Work in a ventilated space with either method, and keep solvents away from open flame. If you're stripping a model you didn't originally build or aren't sure of the material on, the hidden-spot test above is not optional — some resins and soft plastics react badly to solvents that are perfectly safe on hard styrene plastic.
Questions people ask about stripping paint
Is isopropyl alcohol safe for all miniatures?
It's safe for most hard-plastic miniatures, but not guaranteed for every resin or soft PVC model. Test a small hidden spot first before soaking the whole thing.
How long should I soak a miniature to strip it?
There's no single correct time — it depends on paint thickness and how many layers are on the model. Check periodically rather than assuming a fixed soak time, and stop once the paint scrubs off easily.
Can stripping damage a resin miniature?
Yes, some resins react badly to alcohol or stripping solutions. Always test a small, hidden part of the model first — a base tab or spare sprue bit — before committing the whole miniature.
Does the same method work on metal miniatures?
Metal generally tolerates both alcohol and dedicated strippers well, since it isn't vulnerable to the softening/melting risk that affects some plastics and resins. Still worth a quick spot-check if you're unsure of the exact alloy.
What do I do right after stripping?
Rinse thoroughly and let the model dry completely before re-priming — leftover moisture or solvent under a fresh primer coat is a common cause of a frosted, grainy finish.
Plan the repaint before you strip
Since you're starting fresh anyway, preview a new scheme on the model first — decide the direction before you commit real paint to the second attempt.
