As for circulating the fluid, doing this with any process will speed it up. Basically what happens is the fluid around the paint becomes “saturated” with paint, by stirring the fluid you expose the paint to fresh fluid allowing the saturation to spread.

Another tip to try is putting your cups of remover in a window pane or some other warm place, for every 10 degrees Celsius you raise the temperature the rate of removal will increase 2 fold. ( that is at 20c the rate is X, at 30c its 2X at 40c its 4X and at 50c its 8X) dont go to high though as most ketones will begin breaking down at roughly 68c.

P.S.Havent tried on plastic yet

As well as a wargamer, I also have an interest in model trains.

The acrylic paint on ready-to-run models is remarkably tough, but I’ve found a product for removing this works very well on miniatures too.

The only drawback is that it’s a little pricey (£7.25 for 125ml) and will evaporate if left uncovered.
The best way to stop this is to use an old glass container (jam jar, etc) with a sealable lid.

Superstrip works on plastic models without any damage, and models can be immersed for a few hours and attacked with a toothbrush.
This will remove paint and spray undercoats too.

Alternatively, dip the toothbrush in the Superstrip and scrub away slowly eating away through the paint.

I use Goo Off (US/Canada only) for metal models, leave them to soak in a sealed jam jar for a few hours and the paint can be scrubbed off just like the above pictures. On the downside, it does smell bad.

I’ve also used another cheap pine desinfectant with the same results, so my guess would be that any similar brand would work here.

Haven’t had any visible damage to models yet either.

No idea of its toxicity though. I’d wager drinking it aint to be recommended =P

I have started using Purple Power; which i got in the automotive section of Walmart. It is a bit harsher (you should wear gloves when handeling models that have been in it or fishing them out of it) but it removes paint and primer on metal, plastic and resin in a shorter time than Simple Green.

i have had models sitting in Purple Power for 6-8 hrs that came out looking like the above marine photo. 24hrs will take nearly all of the primer and paint off leaving you nice plastic.

I read a similar review on the Bolter and Chainsword where someone tested Simple Green on the off-white Forge World Resin and had similar results to plastic. Apparently some people have reported slight green tinges in the cracks of the resin after using this stuff, but I imagine that can be painted over easily enough, provided it is just the dye.
