I agree with J. Chip. My Zu Def 4s in piano black are 8+ years old. Rare gentle dusting. White gloves or a cloth when moving - again rare. Avoid fingerprints. Don't touch the bare surface. Etc. They still look new.
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?
