Whitening yellowed toys with Hydrogen Peroxide

[Trent]

Can anyone offer an update on some of the things that they used this method on a few years ago? I’m curious to know if the results are still as evident or if some of the yellowing has returned? I read some time ago that plastics whitened in H2O2 are prone to yellowing again quite quickly.

I got a super cheap animated megatron but it’s yellowed

Should i remove the electronics? Will it effect them in any way?

Yes. Definitely take them out.

So i finally caved and ordered peroxide from amazon rather than wait for chemist warehouse to get stock
Turns out it’s creme, should’ve read my screen but oh well

I’m assuming it will still work?

Well i tested it on a test piece and it works
