Am I out of my mind? #obsessed

I used a polish spec'd for fiberglass boat hulls on vintage plastic souvenir snowdomes and CD's with excellent results (forget the brand name).

It smelled/looked exactly like a CD polish that was in vogue 15 years ago, or so, but was 1/10th the cost.

Never tried it on paint.

Thanks everyone! Much appreciate all the responses! 

Most likely anything you do to fix micro scratches is going to make the problem worse. The best coarse of action is limit the cleaning to twice a year and invest in protective, non abrasive covers. Then leave the speaker covered when not in use to prevent dust build up. I have a piano gloss wood finished speaker that I have owned now for over 20 years and they still look factory fresh. Although, if you look super close, a micro scratch might rear its ugly head but I don't worry about it.

Guitar makers and repair guys often use Novus as I do. The 3 versions go from serious scratch therapy to a great sort of anti swirl mark polish.

For years I have cleaned piano gloss speakers using the following method with perfect results:
1) Lightly dust the speakers with a Swiffer Duster.  This will remove the loose dust particles without abrading the surface.2) Lightly mist the speaker with any high-quality auto detail spray.  I had good luck with Mothers.3) Spray the Mother detail spray onto your NEW microfiber cloth, folded into quarters.  Gently wipe the finish until you see the detail spray start to disappear.  Flip over the cloth for a final buff and you're all set.4)  As long as the speakers are not touched, usually you can get excellent results from just going back to Step 1, above, and not having to use the detail spray steps.
To fix existing surface scratches on used speakers I purchased, I have used Turtle Wax Jet Black Car Polish  and plenty of elbow grease with good results.
