I'll take a not-very-knowledgeable shot at this. I saw a piano with very yellowed keys at a used-piano dealer one time. I'm quite sure they were plastic. When I remarked about the keys, he said, "Oh, that will come right off!" He took a piece of very fine steel wool to one of the keys, and sure enough, there was white under the yellow. I don't know if this will always work, and I'm not sure what number the steel wool was. I surely wouldn't want to scratch the keytops. Maybe someone else knows.
