Hi Scott,
Remember Jerry Peterson? He used to sand them down by hand similar to what
was being shown in the video but without the sanding machine after which he
placed them on the polisher to close up the pores again. They came out
looking very nice.

Hmmm, that sounds pretty drastic to me ... I remember one article I read
that suggested using some kind of nut to rub the ivories? Sounds crazy,
but if it works, it works. Do I also remember somebody suggesting oxalic
acid? eek!
