are you cleaning them to repaint them or just cleaning them?

If just cleaning them, I would think simple green would be good...but dilute it. I'd probably do a 50/50 or more solution with water, that stuff is strong!

Just to be safe, I would try a 70% water/30% Simple Green first, clean them up.

If you decide then to dye/paint them, there are certain prep solvents used to 'soften' the plastic so that the color will absorb.
