Hi all!  On the Piano Technicians List there was quite a thread about
bleaching ivories using hydrogen peroxide, H2O2.  Some people acquired
a 30% solution at chemical supply houses in major cities, others used
what they obtained at hair salons.  Some used the sun, others used ultra-
violet lights.  ALL cautioned strongly about the dangers to the skin.
