Best way to clean glossy finish on speakers?

@macg19 ,

You can get into a lot of trouble with a rotary polisher. You can burn right through the finish. However with Menzerna 3500 and a foam polishing pad on a random orbital polisher it is virtually impossible to get into trouble. You would have to throw the polisher at the speaker. It would take hundreds if not thousands of polishings to get through the finish and it is impossible to burn through the finish. You can't generate enough heat. The Cyclo is another safe finishing device but I find it clumsy to work with.

@vandy357  CQ Quartz UK formula. Lasts three years in New England. You have to rub out the finish first and use a professional surface cleaner like CarPro Multix. If you leave anything like fingerprints or water spots on the paint you will seal them right in and the only way to get them off is to rub the panel off and start all over. This is true for any of these products. First time around it is best to do a white or silver car. If you do a black car you will wind up committing suicide.  

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??

Introducing a mixture of all kinds of molecules against the glossy surface can't be a good thing.

@mijostyn I am certainly not good enough with a rotary polisher to use that on my speakers, if you don't know what you are doing with one of those you can burn clean through the paint.

I don't need anything like the CQ Quartz because my speakers are not in the weather that beats up on a wax, the summer sun in the Memphis area is really hard on automobile paint.

@emergingsoul I am not sure what kind of paint is on my Sopra speakers but it sure looks like automotive paint.  I use the products to help protect the finish and make them easier to wipe down when dust settles on them, (and finger prints that always seem to make their way onto my speakers).  If you don't want to use anything like that that then I would suggest a soft damp cloth followed by a dry cloth.  You just have to be careful what kind of cloth you use because they can scratch the painted surface, Griot's has some really good cleaning cloths and other products to remove dust and other contaminates without scratching the surface.

........great thread for once. Where would buy Novus as I have high gloss speakers. Thank you in advance.  

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