We use citrus based stripper at work because it's hard to get rid of solid waste from methylene chloride stripper. Works a little slower and heat don't help it out like the evil shit, but that don't matter on a plastic part anyway! It eats organic paints pretty well. I don't know that we are using it on any poly plastic, as most of ours is phenolic or cellulose acetate butyrate, but it has not wrecked anything for us. Important when so much of your project parts are made from unobtainium.
