Scott Put them under a blacklight overnight. It will take some of the yellow out, but they will not look white because the stain is probably too deep in the pores of the ivory. If you know you're going to have sunny days, you can put them outside in the sun for several hours at a time.

Does anybody ave any good tips for how to accomplish this? The piano is extremely old nd was in a smoker's home for many, many years. I'd also welcome advice n what pitfalls to avoid in doing this job. Thanks in advance! Scott ----- cott A.
