Partial yellowing?

Not me!

I don't want to destroy even an yellowed key cap!

The very dead A500 keyboard I have is going to be "transformed" in CDTV key caps! Yeah, I want a black A500 too. I have enough parts to resurrect at least one badly yellowed A500 (from 3 "zombies").

But I have enough A500 trapdoors and a hopeless A500 case. The original owner had try to "fix" the broken keyboard using a SCSI port on the right side . Badly yellow (=brown!). Also I have one PERFECT A500, who will donate a small part of the trapdoor cover to the experiment...

I like experiments and I have lot of yellowed PC keyboards to sacrifice...pleas e advance

anyways ..I think that there's no way to unyellow any plastic without remove the first yellowed layer....this can be made on a fast way with thinner.. it burns the plastic ...of course this process can't be made on individual keys because you will erase the printed number
however my preferred method is a fine sand paper and patience
but
sometimes the yellow penetration is so deep ... even using thinner it's impossible
