The black polyester finish (so-called "Black Ebony") is pretty hard
stuff and not easy to damage. Still, I would stay with the soft felt
polishing materials that Yamaha offers as well as the Yamaha Unicon
polish. Pledge Grabits also work well for dusting and seem to leave an
anti-static film.
If you are getting deposits of dust, you might wish to check your
humidity. Ideally, your piano should be kept at 42% relative humidity.
Where I live, it's dry as a powder house during the heating season
and, for reasons I won't go into, I can't humidify the entire piano
room. I have a DampChaser humidistat-controlled humidifier installed
under my DC3 grand. When the piano is not in use, I keep it closed and
covered with a tent that extends to the floor and holds the moist air.
Using this humidifier considerably reduces drifting of the tuning.
Also, probably the wool hammer felts retain a consistent resiliency. My
tech has told me of sound boards that have dried out and cracked.
DampChaser is also available for uprights.
