How to polish Wilson Audio speaker


I've ordered a pair of very good conditioned WA Sophia 3 and I'll get it in next week.  May I know how to polish WA speaker?  Someone said use car soft max but someone said better to use piano wax.  Which is better?   

What about in normal period?   Just use 3M cloth or use wet cloth to wipe the speaker surface?

On the other hands, how to clean the drive?  By water? Use alcohol mixed with water?

Personally, I’d contact the manufacturer and ask them what they suggest as a starting point. Then, with other comments people make you will have a good reference starting point to perhaps know if someone found a better product or not.

Novus Plastic Polish is a possibility but I don't know how it compairs to other products.
Your Wilson's should come with a micro fiber cloth.  Wilson recommends periodic wiping of the speakers using a horizontal wiping motion to avoid swirl marks.  You do not need to wax your speakers as they are not exposed to toxic environmental elements and sun like a car.  For finger prints etc, Wilson recommends a product called Plexus Plastic Cleaner which is safe for painted surfaces.
Dust lightly with Swiffer, then use a soft microfiber cloth and an auto detailing spray like Griot's Garage speed shine.  As stated above, clean in straight lines to avoid round swirl marks which are more visible. I believe Wilsons use automotive paint and you can find a lot of information in auto detailing videos, especially ones for dark cars.
