How To Clean Piano Black Speaker Finish?

A friend who is a guitar repair genius recommended Novus...a  plastic polish supposedly, but he saw it at the Collings guitar shop  and he was sold...so am I...I use the lightest version of the 3 available (#1) on everything from my motorcycle helmet face shield to my nitro finished acoustic guitars...amazing stuff.

I too use Novus, to polish the plastic wrap, and even lacquered finish, on the vintage drums I restore. The Pro's choice!

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

Not sure if you saw my pics but Novus is what I finalized my KEF’s with.  I actually have a bottle of Novus on top of one of the speakers in one of the pictures :-)

Gerlitz looks like good stuff as well 👍
