Somebody on some forum or blog mentioned stuff they picked up at a dollar store, I don't know if this is the same stuff they were referencing but the other day I picked up a jug of LA's Totally Awesome concentrate cleaner at my local 99 cent Store. I wish I had documented my first trial but wow so far so good!
I soaked these goblins for about 48 hours and the paint literally sloughed off and they cleaned up with a minimum brushing. No paint left stuck in the nook and crannies.
So I'll try and document my second test here. Ive got a couple more goblins and a heavily painted space marine. I'll give them a day or two and post the results.
It turned very milky after soaking the first two gobbos so I'm a little concerned about how re-usable it is. To that end I've dropped an old Mighty Ugezod (sorry no before pic) into the used stuff and the other three into a new pour.
OK, I'll be back in a few days with results.
