Hi Blaine,
Was that C3 from the 1980s or 1990s ? If it has "Ivorite" keytops, the issue is humorously called "Ivoritus". I was the Yamaha tech for the local dealer during that period, and Yamaha used to provide new keys and cover the labor for replacement. They don't do that anymore. I installed many of these replacement keysets, a few times twice on the same piano.
You can sand and polish the keytops but that's a lot of work work well, and it won't last. The problem will just come back. The problem is worse on piano teachers pianos or any Ivorite piano what has more than one player.
Yamaha will provide a newer version of "Ivorite" keytops. The problem is the expert labor to remove and install properly. You could go with acrylic molded keytops, but for a "C" series Yamaha with discerning pianists, I'd recommend something better, Tharan or Ivocor which we install in our shop. Tharan is what's installed on Fazioli and other high end European pianos. These high end mineral plastics such as Ivocor or Tharan have a feel that duplicates the ivory feel that pianists like.
Hope that helps,
-Dean

Subject: Yamaha with discolored keys
A customer has a Yamaha C3 grand with the textured keys that are discolored and grimy in the heavily played area. The student is complaining about the texture (though there are several other complex issues involved).
I can get a new set of keys from Yamaha or replace the existing key tops but this could get complex and expensive.
Who has experience with these textured keys?
Will a bleach/cleanser solution adequately remove the discoloration?
Is there a treatment such as wax, shellac or laquer that would fill the pores and improve the touch?
