Terry (Tezza) has posted a pretty thorough summary of his experience (not to
mention his most excellent videos of his various other restoration and repair
efforts):

I would be interested to see how the full scale test goes.

I tried it on some key tops. Works great.
I’ve been meaning to do some larger scale tests. Even just Hydrogen peroxide
from the store at 3% and some oxyclean works with a UV lamp works. I used the
ones they sell at Staples for checking currency, and placed a shallow container
with some keys under it overnight.
I’d rather do full emersion with a fish tank than paint on the jelly version.
I think the blooming problem would be avoided that way (as long as the light is
scattered and there’s no shadows where you’ve got differing exposures of UV).
As for the long term problems, the only thing I can think is that somehow the
yellowing goes deep, and somehow the treatment only penetrates the surface, and
somehow older yellowing comes up to the surface.
I guess only more people trying and sharing their experiences it over the
long term will tell. Unless some Masters or PHD student is looking for a thesis
and takes this whole idea into the lab and figures it all out.

Also: don’t get acetone or nail polish remover on Commodore 64 dark brown
keys. Messes them up with a frosty coating that makes them look dirty.

Worth a try though, if your C64 looks as bad as the other sample ;-)

Not exactly a new idea.
This has been around for >5 years

Hi all I just wanted to bring up this new chemical procedure for getting
your systems back to their original colour. As we know Computers and other
electronics can become yellow with age. This is caused by exposing the system
to UV light. Bromine is the reason for this. It was used as a flame retardant
in plastic during the 80's and 90's. Now there is a way to reverse the
yellowing with a chemical formula called RetrObright. Many Nintendo collectors
have had great results using this method. Why cant we?!
