I recommend Gerlitz Smudge Off which was personally endorsed for polishing high gloss finishes by an ultra high end dealer. A quick spray onto a MF or other soft scratch free polishing cloth and a gentle wipe cleans exceptionally well while leaving no residue or streaks. It's commonly used on high gloss guitars, and also works well on any gear that's metal, glass, chrome, etc. https://smile.amazon.com/Gerlitz-SMUDGEOFF-Smudge-Spray-Cleaner/dp/B000WIFUDW
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?
