I just bought some old 1/32 Airfix,Matchbox soldiers that were painted by a kid or a blind monkey.I'm in the process of removing the paint using easyoff oven cleaner method.I spray on the oven cleaner, then wait a couple of hours and brush with an old toothbrush... repeat until clean.I stopped using brake fluid years ago because I heard it removes oils from the plastic(have seen damaged models from this method).Some day I will buy an ultrasonic cleaner for this job but that'll have to wait.What methods do you use,any other methods should I try?
