No denying the lightening process has brightened it beautifully. This has got me thinking of trying a couple of Peroxide experiments on coloured ABS and 'Bakelite'....

Will the strict peroxide soak work as well on other colors ?

I have done a search on here and read a number of threads re this. Coloured plastic results appear to be variable.
The part about whitening plastics I like the much is that it stemmed from someone experimenting with whitening yellowed Commodore Amiga computers, and from there it just spread out like a wildfire of whitening of all kinds of yellowed things, it's brilliant... 
I don’t know where the method originated but as that chap did it some time ago, do you know if he ever did a vid showing what it looked like, for example, 1 year on?
I’m wondering how long his bleaching process lasted before the darkening began to revert.
