Was Action cleaning - Ivory keytop cleaning

[Lawsonic Pianoforte Services]

Here in "Sunny South Africa" (ZA  = international code, SA is Saudi Arabia)
it is very easy to put a set of keys out in the sun with a coating of
Hydrogen Peroxide (costs about R6 =$1) applied every couple of hours,
depending on how yellow they are, then you cut them down with wet&dry
sandpaper, then polish on buffing wheel, with buffing soap.
