    The peroxide reverses the yellowing but does not 'cure it' so that it never happens again. It is still the same plastic prone to yellowing as it always was so it was bound to return.

    May take weeks, months or years but it will return. Nature of the plastic used.

    yeah , unfortunately the plastic used are the ones prone to it... I think same as the plastics used for old computer bodies/cases (which yellows like heck too). Good thing the formula I think has been changed since then.

    That's gold

    FYI, I put one of the newly whitened junk Jetfire wings (pic a few pages back) in the oven at its lowest setting (170F). The yellowing came right back in minutes, so heat certainly has an effect. Plus the wing shrunk a little bit, lol.

    How is it on non-white plastic that's slightly yellowed? I have a Hotspot which looks a little manky and it might be the same sort of thing?
