What do you use to keep high gloss speakers clean?

I second that: "Damp microfiber cloth followed by a clean dry microfiber cloth."

Wizards Mist-N-Shine motorcycle detailer.

You're welcome. 😏

Feather duster or Swiffer, no liquids whatsoever. Buff out any fingerprints with a microfiber cloth only. I had black high gloss speakers for two years in a south facing room with floor to ceiling windows and I am picky about appearance. I have high gloss white speakers now, which need dusting 10 x less often :)

I use saliva spit shine

I use Plexus. Also never buff in circles. Best to go on one direction
