retrobrite (or however it's spelled). I am talking many many threads,
photos, experiments etc. I have a corresponded with the creator a few
times. Tez has a nice web page that demos the results of use.
The bottom line .. Good but temporary results. May over a long period be
harmful. Best to use just before you show item at a vcf, or if you are
sleezy ...use before photographing to sell on ebay. Within two years 75%
of the yellowing returns. Caution ebay buyers..you might be buying a
retro-brited Apple II! Looks too good to be true?
