Best way to clean glossy finish on speakers?

It should be available at any motorcycle dealer.   It is popular for plexi windshields 

My glossy finish looks fine without any polish.  I just want to clean off the surface. Why would anybody polish an already existing Nice looking glossy speaker finishes??

No clue. But applying a synthetic automotive paint sealant as I suggested above can protect that glossy finish and make it easier to dust and clean.

@garebear: Novus sells their products on their website, and so do Amazon, Walmart, Home Depot, and DAP Plastics. Buy $25 or more and Amazon shipping is free. If you have a good plastics supply house in your area they should too, mine does.

@mijostyn,

I believe enough time has passed, couple of years I’d gather since my first & only observation give or take. Sending compliments on one stellar furniture wood shop you’ve put together / assembled, a labor of love indeed. Question if I may Sir, maybe somewhat OP related … nah, likely near impossible! :-) Any chance you’ve had the luxury operating any of Festool’s Line? Particularly Fes’s variable speed random orbit sanders along side and paired with their dust collection Vacs. Somewhat more costly in comparison compared to that of unsaid competition many others offer, however second-to-none in shear performance equaling less effort & time spent. Top tier phenomenal collection puts one’s H&L sandpaper inventory dwindling down to lets say 7 fold.

@dabel ,

Festool makes excellent gear. Their sander s are top notch. The problem is the price. At times they try to hard to be different like the Domino tool. Having buried myself in Milwaukee batteries I generally stick to their tools and I have not had a bad one. The one exception is Fein, another german company. I use their vacuum for dust capture on all my hand power tools and I have a 1/2 sheet Fein sander that I can't kill and I have used it to sand floors! I use a Lamello Plate joiner and Porter Cable routers.
