Whitening yellowed toys with Hydrogen Peroxide

[Doubledealer]

can you please send us a site to where you heard this from?

ive polished metal before by using that technique (600 grit to 2000 grit or finer with different cross strokes). It polished up really well to a mirror finish, but from experience, it took quite a bit off the metal and any uneven strokes/pressure will cause uneven abrasion.
so if you were attempting that technique on a thin plastic G1 car windshield then i doubt it will stand up to that method.

how deep are your scratches/smokiness?? if they aren't too deep, perhaps you can try polishing compound (http://www.hlj.com/product/FNS55937)
and then maybe toothpaste or a polishing cloth?
i haven't tried it yet but it should be less damaging than sandpaper?

Hmm, after hearing your experience with the polished metal I think you're probably right, the already thin G1 car windshield would most likely become paper thin or worse.

I wouldn't say the scratches are particularly deep. They're more like frenzied surface scratches, kind of like the underside of a CD that hasn't been cared for all that well. Thanks for the HLJ link, I might have to try the polishing compound out sometime!

Well heres my first attempt at using H2O2, the jar was in the sun for 3 1/2 hours. Pretty good but I'm still at the same level I was 20 years ago for applying stickers

Hmm maybe '87 toys can safely be whitened, provided they aren't super yellowed. Or is this an '86 figure?

Scourge is '86. Not sure what difference that would make though.

As long as he isn't the target master version ('87).

But I was saying this because someone (it may have been Kup) said that a lot of the '87 toys didn't react well to H2O2 and would get weird white spots.

Yeah I saw it work well on a scourge Kup did - was my inspiration

it's looking very good!

Thanks, hes gone from being at the back of the 'sweeps' to being up next to their leader - TM Scourge!

i think what kup meant was that H2O2 didnt react well with the blue plastic on the little target masters buddies.
