    Retr0bright works well but it was designed for ABS plastic. Not sure if playfield posts are ABS. The ABS yellows upon exposure to fluorescent light which causes Bromine added as a fire retardant, to break free of its chemical bond. This is the yellowing you see. I've used the process quite a bit with very good results. First thing would be to find out what kind of plastic the posts are or just try it out and see what happens.

    I just reread your post and realized you were talking (I think) about the playfield plastics and not the posts. The retr0bright process will very likely remove the artwork from the plastics. It's a caustic mix and I've only used it on solid color plastic that I knew was ABS.

    Quoted from nerdygrrl:

    I tried the peroxide and Oxy Clean mix last night on the clear plastics from my SI. It didn't do squat. They are still stained.

    Sometimes it takes up to 36 hours. What were you using for UV light?
