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?
