Best way to clean glossy finish on speakers?

Menzerna is a top shelf brand but once you add a machine to the mix you need to be careful if you do not have prior experience. Lot's of tutorials on YouTube though.

Autogeek dot net is awesome - they have everything you could possibly need - I've been buying from them for 20 years. 

I get my wife to all the dusting/cleaning. Highly recommend that.

I guess she must be more than happy doing so. Make sure though whatever the gadget she is using won’t microscopically scratch the surface please. Someone in this thread even worries about the cover fabric "rubs" the surface more so than abrasive, intrusive cleaning using all of the solutions recommended here.

I use Zaino products on my black gloss Focal Sopra 2's.  In particular I use their grand finale spray seal to remove dust on a regular basis with a soft cotton cloth.  I use their all-in-one about once a year to give the finish a nice coat of protection, these products make the surface a very slick.  I only handle the speakers with white cotton gloves if I need to move them.  So far I have only had one scuff mark on one of them, which came off with Zaino fusion polish.  They make good stuff, I have been using Zaino on my automobiles for probably 15 plus years.  Right now I am looking into a ceramic product, the only problem is there are so many out there it is hard to weed out all of the junk, I have tried a couple that were just that.

I use a product called Novus. There is a 1,2,3 versions for additional polishing.
