People have been doing US SNES' (purple plastic), keycaps, Atari 400/800's,
etc. without any apparent ill effects. If you get too strong of hydrogen
peroxide I guess some of the intermediate reactions can have bleaching
properties of their own. I would tend to believe that if you're doing small
stuff that it would be better to do an immersion in a tub of the stuff in
liquid form instead of the gel-- seems like the gel would be hard to get
even, and if there's some foaming it could leave dry spots and blotchy
results...

I have an old Fluke benchtop multimeter that has turned more brown every
year-- I might try it on that. (Long ago I had a Mac Plus that was
practically rust colored it was so bad... Long gone now though...)
