How To Clean Piano Black Speaker Finish?

What do you use to clean your speakers Piano black finish?  I am using a slightly damp microfiber cloth.  So far, in 2 years, no scratches.  Is there an easier way to keep them clean?  I have used a very clean wool duster a couple of times but it doesn't help fingerprints like when I move them.  Anyone?

You can purchase piano cleaner fluid, and use a microfiber cloth or similar (e.g. piano cleaning cloths).
