I have a microfiber cloth and distilled water and isopropyl alcohol.
I can use all this to clean a TV screen and my glasses, but is there a preferred way to clean pristine glossy finish on speaker cabinets so that trace scratching does not appear?.
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
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.
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.
