I've had good luck buffing double-shot molded keytops
back down to the original color and finish while
removing a minimum amount of material. IMHO, this type
of yellowing and chalkiness is not at the surface, but
it must be from exposure of the plastic to ozone, UV
light (flourescents?) or possibly smoke. I use metal
polishing compound and a buffing wheel, then finish
off with car rubbing compound. This process is
tedious, but makes an _enormous_ difference in the
appearance of equipment. Note, I mentioned "double
shot molded"; obviously, pad printed keys (virtually
every cheap keyboard made afrer 1985 is made with pad
printing) is just going to come off. You need to look
at the key from the bottom in order to determine this
for certain.
