Yellowed Ivory

I used to clean my piano keys with a solution of vinegar & warm
water - this would also, marginally, whiten the yellow.

This is an official retraction folks…my brain told my
fingers to type the wrong thing. In my last post I said that
Ivory is 70% Calcium Carbonate. It ain’t so. Ivory is 70%
Calcium Phosphate. Please forgive my mistake (and be glad that I
don’t write the tech manuals for your local Breeder Reactor.)
