Go online to a musical instrument store (Shar, Johnson Strings) and get an instrument cleaning cloth (like those used on violins). Also get a cover for your piano if you have pets (cats) that will jump up on it. Keep the top closed when not in use to keep dust and debris from getting inside the piano.

no problem and enjoy your new "baby"! Do you play?

Use a soft cloth diaper for dusting and exactly follow the manufacturer's recommendations.

What finish is it?

Ooh la la!

If you keep things closed, then you're not really cleaning keys or interior, and I think we always just used pledge on ours. The surface of a black piano is pretty solid finish. Soft cloth.

Pledge on a microfiber. But I have a natural stained piano. The black ones are masochistic. Every fingerprint!

No pledge ever . A micro fiber cloth that is used only for the piano , washed separately and no dryer sheet. I keep mine in the book storage under the piano bench. I wring the cloth out in hot water wring til almost dry and works very well, have been doing it for 10 yrs with no scratches.

no pledge or anything else on musical instruments. It will completely ruin the finish.

We do what Patricia Colwell does. We have a satin black piano and no scratches.
