Duaine, The site Avery Todd listed in his post has some great info but you can also just use regular hydrogen peroxide brushed from the drug store. When using peroxide it will raise the grain so sanding and buffing afterwards is a must. I place the keys (usually still on the keyframe) out in direct sunlight on a sunny day. I paint hydrogen peroxide on with a brush every 15 min or so as they dry. Yellow spots or really yellow keys may take several days to bleach out. After bleaching I glue down loose ivories with glue wafers and clamps. (Pianotek and Schaff carry them) If they are just barely coming loose I may wick some thin CA in there to hold them, but if in doubt I pull them off and use a new glue wafer. I then sand the tops level and repair the chips with the Acrilite II ivory repair system that is advertised in the back of the journal. (If you don't get the PTG Journal I will be happy to email you the info) This is a great kit and if you will be doing many of these I highly recommend it. I finish off with buffing on a cloth wheel.
