Stripping paint from plastic warhammer miniatures

Getting rid of a (bad) paint job on a Warhammer miniature is a universal wish. With metal miniatures it is easy. You toss them in a pot of aceton (or in the bad old days in paint thinner) let them soak for a day (or a week), grab a (hopefully old) toothbrush and start scrubbing. Dump model back in the aceton and repeat as needed. Stripping paint of metal is easy and I'm not going to waste more words on it. In this post I'm more interested in stripping paint of plastic models. As the wait for my order of a large tub (bathtub full) of Vallejo Sepia wash is slightly longer then expected I got a chance to try a new method of stripping paint of my plastic models.
(update with extra scrub at the end of the post)

Who will rid me of this turbulent paint job!
