Wool Wax is for lacquer finishes. For polyester finishes use the #12 black rubbing compound and 3/0 steel wool from Mohawk. Windex is a good cleaner but it will remove the Satin Wax that was applied in the factory leaving the satin finish milky and streaked. Therefore, not good for pianos--just windows. This wax will need to be re-applied to get the satin black color back. There is no need to use steel wool in the cleaning process. It's true that some parts of the older Yamaha pianos were finished with something other than polyester. That was lacquer, not verathane (or Urethane) I hope this cleaning advise was not directed to the owner of the piano. That could lead to some real trouble. It's like advising an owner to try tuning their own piano with a socket set, or even the proper tools. >>> "David ilvedson" <ilvey@jps.net> 12/22 1:55 AM >>> If if comes to that I would use WoolWax and steel wool with the grain. It's a lot of work but can work wonders...
