Greetings list, I'm with Dave Nereson on this one Ken.  Hydrochloric =
acid, a flourescent strip light and lots of patience are needed to =
whiten ivory.  I use one strip bulb, which must be left on all the time =
including overnight.  Arrange the keys underneath the light and apply =
the acid with cotton wool several times a day.  It can take a week or =
two depending on how yellow your keys are.
When they are done, buff the key tops with a buffing wheel if possible, =
to make them shine.  Do not get any acid on your skin, so wear gloves.  =
In the UK you can only get the acid from a chemist, who will want some =
proof of what it will be used for.  Good luck. =20
