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.
