Jeez.....it's not rocket science folks. The speakers are not outside, they will not have any bonded contaminants. So DON"T use clay. Use some Mequiars Ultimate Quick Wax and a quality microfiber. That's it. Polish in the same direction....back and forth, not circular. You won't see swirl marks unless the sun is reflecting off them through a window. It's paint and basic paint care is pretty simple on a new finish.
How To Clean Piano Black Speaker Finish?
What do you use to clean your speakers Piano black finish? I am using a slightly damp microfiber cloth. So far, in 2 years, no scratches. Is there an easier way to keep them clean? I have used a very clean wool duster a couple of times but it doesn't help fingerprints like when I move them. Anyone?
