Un-Yellowing Keyboards?

[M-88]

I have a few keyboards that were made around and before 1995. When I got them a few years ago, they were yellowing. Haven't yellowed much in the few years I have had them, but I would like to get these back to white/gray. Is there anything I can do to accomplish this?

I was thinking some sort of powder bleach - but would that damage the texture?

I suggest you read this thread on an Amiga-forum...

It seems that the yellowing problem is solved.

Furthermore, read this thread, which was the 1st listed when searching "remove yellowing"

Thanks for the link. Where can I get the 30% h202. The stuff sold in drugstores is only like 2% right?

According to the article you can get it at beauty supply stores.

Beauty supplies stores sell up to 20% strength, that's plenty strong enough.

I just got something from a company called Prochem.
It's called Urine Rescue.
It's not less than 20% hydrogen peroxide, and not more than 40%.
Runs about $ 22/gal.
I've got a little experiment going right now on some parts.

Thanks for the tips. I'll check at a beauty supply place ... I won't need a big amount so that should work.
