Got the Hydrogen Peroxide in cream form (hair bleach) and a low energy 11W "BlackLight" tube for my desk lamp...
Tested some old very yellowed Amiga keys yesterday, just brushed them with a mixture of the cream & some OXI laundry cleaner. Sat them for 10 hours with no UV light. Result... Nothing... not even a slight change whatsoever...
So tonight Im testing the same mixture but this time with the UV/BlackLight...
The pics below show an old and very, very yellowed VIC 20 case I got from eBay last week and some key caps from and old A1200 I also got from eBay, which once again was very yellowed. The A1200 trapdoor panel in the picture is from one on my own A1200s and is just to show how the colour of the plastic should be...
Start of Test... Normal Light
Start of Test... With UV/BlackLight on...
Gonna give it another 8 to 10 hours and see if I get any results this time...:nervous:
