Best way to clean glossy finish on speakers?

If only there was a wizard

I wonder what chatgpt would say. 
Maybe this website will be replaced

If you do end up with fine small scratches on the piano gloss black finish, try PS 21 paint cleaner with a high quality applicator  It works for me every time

Also great to use on you toy car paint

Use a high quality car wax. For light swirls and scratches, use the same methodology as for car detailing.

FWIW, I also use car wax on all my guitars to protect them from skin oils and acids. It works on tools, on my Weber grills, especially in Hawaii, where corrosion will rot anything not protected. 

OP,

Great question. Here is what ChatGPT says:

To clean the glossy finish on speakers, use a soft microfiber cloth to gently wipe away dust and fingerprints. You can dampen the cloth slightly with water if needed, but avoid using harsh chemicals that could damage the finish. If there are stubborn smudges, try using a small amount of mild soap diluted in water. Remember to dry the surface thoroughly afterward.
