Well that title should up the hits a bit.
I've long heard about Simple Green and its ability to strip paint from toy soldiers but until now i haven't been able to get my hands on any.
I have been using spray on oven cleaner which is pretty nasty stuff.
My first test has resulted in paint coming off when brushed with a nail brush after only six hours. Near complete paint removal has been had overnight. I'm really impressed with this stuff and will attempt plastics with the next batch to go in the soak.
