ivories

[CAPSTANDAN@AOL.COM]

Hi there.
I recently had an action in my shop with 75% "yellowish" ivories ,  The client
asked if I could bring them back to their original white color.  I said I
would do my very best.   In short, After sanding them lightly with a 350 grit
sand. paper
and applied bleach on them, followed by laying them for many hours in the sun
-
unfortunatelly not much of a change took place. (that method was suggested to
me by another local piano tech.)   Does any body have another proven
sucssesful
method for that?
I really would appreciate your input.
