I just wanted to point out that Acetone does not melt plastic models for removing paint, many people, forums, etc. had said so and so I went with Simple Green - after 36 hours of sitting in it and a few hours of scrubbing I made very little head way. Acetone was an instant fix and cleaned my mini's up nicely.
Don't believe the hype! Just be sure you don't let them soak in acetone or they will soften up and break easily when scrubbing. In and out.
