How To Clean Piano Black Speaker Finish?

b_limo, you are absolutely correct taken in context so I owe Millercarbon an apology. No I have never won a concours, just a Make a Wish contest.
I am sure the mini was a PIA. Who the f--- would do that to a Mini. The Cooper S is a really fun car. I think it may be the best handling FWD out there. It certainly is the best I have ever driven. Porsches are great if you work on them yourself. If not they can be a money pit. I have plenty of scraped knuckles to show for it. Audi just announced they are finally going to bring the RS 6 Avant to the US. Boy am I going to have a hard time passing that one by. The ultimate stealth mobile:)
Anyway, what kind of finish did you use on the Kefs, precat lacquer? Gutsy thing to do.
I have watched several episodes of AMMO. Very informative. I think he is in NYC where there are plenty of megabuck cars for him to work on. He drives a 911 on track. Smiley has the cup car nose and wing. I have had him on track several times. Rudy is too scary for that. He goes beyond my capability real fast. 
Stereo5 they are always going to say that for liability reasons lest you use something like brake fluid on em melting the finish off. Trust me on this one, an instant detailer like Meguires 34 which is mostly distilled water will do an excellent job, not harm the lacquer at all and leave you with a nice shine. I use it on my subs all the time. 
 

Jeez.....it's not rocket science folks.  The speakers are not outside,  they will not have any bonded contaminants.  So DON"T use clay.  Use some Mequiars Ultimate Quick Wax and a quality microfiber.  That's it. Polish in the same direction....back and forth, not circular.  You won't see swirl marks unless the sun is reflecting off them through a window.  It's paint and basic paint care is pretty simple on a new finish.  

Some piano black finishes have a very thin UV cured clear coat like Taylor uses on
their guitars.  They have a polish specifically for this type of finish.
You can purchase it on line at music stores and Taylor guitars.

I've owned a few Taylors and still own a couple of 'em, and Novus works on the poly finishes as well.

Novus also works really well on turntable dustcovers.
