I've never retrobrighted anything because I always had a hunch this would be the case. It turns out I was vindicated. We all know full well that oxygenation is one of the things that deteriorates many materials, including embrittling plastics, and what you're doing with this stuff is literally just oxygenating the shit out of your plastic in order to bleach it.
For stuff that I've really cared about de-yellowing, I've always just cleaned it thoroughly and painted over it. This has the added bonus of the paint being an additional protective layer rather than a destructive chemical reaction inflicted on the material itself. Sure, it sucks that you also paint over any logos printed on it or whatever, but you can recreate those with stickers if you really care. I figure that if anybody can't identify what an NES or Dreamcast or something is shaped like, even without the logos on it, they're probably not invited to any more of my parties anyway.
