Hi,
What is the most effective way to remove acryl-paint from a resin figure?

I used nail varnish remover to take acrylic car primer off a resin model, it worked fine and didn't affect the resin in any way.

A dip in Windex also removes all traces of acryl paint.

Pure alcohol. So spiritus works well, it's cheap and you can get it everywhere

Of een flesje alcohol bij de apotheek of drogist halen je hebt ze van 70% en 96% hoe hoger hoe beter (niet voor consumptie )
Of spiritus werk net zo goed .

I have used a dishwashing product called Fairy Power Spray to remove acrylic paint from plastic and metal figures and plastic palettes. Harmless to plastic and to enamel primers. Spray, leave, dunk in warm water and scrub with a toothbrush. I have no idea if this is available outside the UK. It's something you spray on your crusty pots and pans before washing to loosen the crusty bits.

There are specific model paint removers available. AK Interactive certainly do one.

Oven cleaner will do it, but as has been suggested, isopropyl alcohol will really strip acrylics and leave enamel primer intact.

Thanks for all your tios. I'll go for the spiritus first. Easy to get.

I have read (and have used) the following will clean acrylic paints:

The blue window cleaner (Windex)
Isopropyl Alcohol
Castrol Super Clean
Oven cleaner

For lacquer I used brake fluid once. Took off the paint, but also softened glued joints and parts came of the model.

I have just had to strip a medium size part and I used oven cleaner. I placed the part in a mug, covered it in oven cleaner and then left it for 24 hours.

The following day I placed the mug under the tap and ran the water for a few minutes and when I took the part out it was pristine and back to plastic, I did not even have to scrub it with a toothbrush.

also Brake fluid works

I'm a big fan of oven cleaner, works for both acrylic (tamiya, Gunze) and enamels (Humbrol). I just stripped a figure I had started painting maybe 15 years ago with humbrol enamels. Overnight in Mr Muscle Heavy Duty oven cleaner and it looks as good as the day I assembled it.

Best remover ever. Safe for plastic, safe for clear parts. I know, because i have used it and it's brilliant.

I am using two different solvents for acrylic coatings:
- ethyl alcohol (the one from farmacies or supermarkets). It is quite efficient, not very costly and most fundamental, non-toxic.
- oven foam cleaner. It is less efficient than the alcohol and it is toxic. Need very well aereated place and avoid breathing. Also yiu really need using gloves.
For enamel paint the best result is obtained by dipping the model in a soda-water bath. Need to remove the coating with toothbrush while sunk in the batch. Toxic and very agressive. Need to be very careful during preparation of the bath and while using the toothbrush.
None of the above trestments damage the polystyrene . In many cases, unglue the parts , so you can rebuild the model after washing and rinsing several times with water. I use to also wash with dishwasher Fairy or equivalent, specially after the two last options.
Recommendations: do not use methylalcohol. It is very toxic by contact sith the skin. People use to confuse it with ethylalcohol (non-toxic).

Hi, I use isopropyl alcohol with my airbrush. Just blast over the figure. Also I do the same to chipp the white camo.
