[pianotech] Bleaching ivories

[Roger Gable]

Rick, et al,
Our long time technician Bill Smith demonstrated years ago at a chapter 
meeting, a method I've used with good success without the risk of warpage. 
Soak a paper towel with Clairoxide -- a product used by hairdressers to 
bleach hair -- and place the towel on top of the keys while exposed to the 
sun. In two days (changing the towels periodically) the result is sufficient 
for most yellowed keyboards.

Richard,
Has anybody had success using UV lights to aid bleaching of keys?
