I have outlined my experiences and techniques for removing yellowing here: https://a4000bear.neocities.org/overclock/Retrobrite
There are also pictures of the process being done on a VIC-20 case.

I did look at this but the cost of a plastic tub,uv lamp( no sun in England ) and retrobrite was a bit to expensive for what I wanted for one Vic20 case.
Thanks again for the link :D

You don't need the UV lamp, but if you don't have one keep the container somewhere warm (do you have an airing cupboard?) and be prepared to wait a few days, and it will change color eventually.

I did do some case brightening using H2O2 and good old Aussie sun. The results were mixed. I tried a VIC case and it worked brilliantly. It was all back to its original glory and looked great. However, the Breadbin 64 I tried failed miserably and left everything splotchy and all. The same happened to a C64C. I acknowledge that at least the Breadbin 64 was a bad idea but the 64C should have worked. Fast forward 6 years, the VIC is just as yellow as it was before the treatment. It may be a great idea if you plan to sell one but for a keeper, a can of spray paint is a better idea IMHO.
