    Just curious, can you keep the jar of hydrogen peroxide and reuse it over and over?

    Yes you can. Just make sure the lid is sealed so that it doesn't evaporate out.

    just wanted to confirm what kup has said and that you CAN reuse the peroxide multiple times.

    It also works on coloured plastics too.

    sunlight is not always constant over here atm so im currently using a UV lamp indoors. im also using a motorised jewellery display turntable to allow even exposure to the UV.

    the results have been pretty good so far.

    however, i've got a question for those who say that they've used 35% concentration. do you mean 35 vol and not 35%?

    how are you guys obtaining this? the max i can buy is 6% / 20vol?

    I have never found more than that amount. I would also be interested in a higher concentration.

    perhaps TheHandsomeCrab can enlighten us where he gets his 35% ??

    i certainly look forward to the prospects of using it for only a few hours rather than a few days...

    yeah, i was talking to Kup about retr0bright a while back...
    sounds promising if you can make the gel form and only apply to areas where you need it. saves from unwanted bleaching/whitening of adjacent sections that dont need it.

    however, with "Figure 3. Lorne’s Osborne 1 experiment", is it me or did they compare 2 completely different machines (refer exhaust unit)?? looks a bit suss to me but meh... peroxide + UV works.

    I like that, plus you don't need to "bath" the parts.

    Funny, I remember mentioning this a long while back. Haven't actually tried it myself yet.
