I am not an ivory expert either! However I have had some experience cleaning cracked ivory key tops. I found that most 'blackness' was due to household cooking /finger grease. A 'caveat', we do not know the the thickness of the ivory, the narrownes of the cracks. Are they splinter, or wide enough to use a solution to clean said cracks? We also do not know the quality of the piano in question. Please help.
