    Wow. That Fort Max looks amazing after the "treatment" was done.

    Soaking the parts in Hydrogen Peroxide? Wouldn't that just be eating away a little bit of the top layers of the plastic?

    The results are definitely impressive. I'm curious how this would be with standard hydrogen peroxide you can pick up at wal mart or drug stores.

    However, I'm thinking those figures will re-yellow with time. It could take years though, but who's to say just another retreatment wouldn't fix it again. My understanding is that yellowed plastic is ruined. The treatment could just be taking off that "top layer" of plastic, but it being so thin as to be unnoticeable. The degradation would be liable to continue, but I don't know that you're any worse off on significantly yellowed items.

    Holly crap! :jawdropper: That is awesome!

    I have 3-4 macross winged G1 jetfires that are begging for this treatment, actually I bet I can find all sorts of junkers that can be brought back from the dead. I cant tell you how happy I am!

    Woah. That stuff gets expensive, but I suppose there is a limited market and thus a higher price. Perhaps I can get NASA to donate some of their 90% stuff for a yellowed Sky Lynx.

    Yeah it seems that 30% is just right, but if you read the jetfire section, only part of it was dipped but the whole thing turned white. What if there was a way to put a screen to keep the plastics from being submerged and just use the vapors? Agian, only half was submerged but the vapors cleaned the rest of jetfire......

    That might also be an alternative to disassembling the entire figure.

    Interesting... My Fort Max has some yellowing that needs fixing but I'd need a ton of the stuff to have enough to soak it in and then there's the cost of a new sticker sheet for him... I'll end up paying more for the treatment than I did for the toy.

    This has to be the single greatest discovery in Transformers toy restoration since actual Chrome paint, followed by Reprolables.

    Read the linked thread, people have been having good results with 3% too, and its only a few bucks at your supermarket. It takes longer, and the results aren't quite as good, but it does work.

    Mannn, I'm so excited to test this on several items I have like a Jetfire, a U.S.S. Flagg from G.I. Joe and a couple Storm Shadow figures!

    Thanks for posting! My only concern too is if there is after-effects such as it returning back to yellow.

    That is amazing....but with that strength of Hydrogen peroxide (standard/industrial-27.5-35% or the food grade 35%), please be careful because it can kill a person if they inhale it. What it is doing is just bleaching the figures. It is hard to say if the yellowing process will come back or not.

    safety with Hydrogen peroxide

    In terms of my own figures, I am fine and have not seen the yellowing process.

    How do you protect the areas that are painted that you do NOT want to get damaged, like the Jetfire's red stripes?

    I'm a little embarrassed to say I saw the beginnings of this discovery way back in July or June when it was first posted at the Action Figure Archive - A vintage 70s & 80s action figure collectors guide, online store & forums forums but I forgot about it.

    I'm a little weak on my chemistry, but I'm guessing this works like so: Yellowed plastic is yellowed because it is oxidized (rusted). H2O2, which is unstable and naturally releases that extra O, normally forming O2 + H2O. With the yellowed plastic present, the free radical O forms a stronger bond with the plastic-bound Os and and is able to rip them out of the plastic. Your end products would be O2 + H2O + de-oxidized plastic. So, you're not actually removing any of the plastic, paint, etc, which I think explains why the paint looks intact in that thread's pictures. Is that correct? Chemists?

    What about the plastic. Does it alter the structure ? does it become more brittle ?
