I prefer to to remove no ivory even if the keys are cupped. I did a
BlŸthner overstrung last month that had very grubby and very worn
keys. The keyboard now looks very respectable and I shall have to
tell any prospective customer that the keys are not as good as they
look, If I'd sanded them level they'd be about 1/2 a millimetre
thick.

Just ordinary powdered chalk (CaCo3) that you can buy at any builders
merchant's. They sometimes call it line chank (for plumb lines) and
it's also known as whitening or whiting.
