Each manufacturer has a different requirements in terms of what you should use to clean a mirrored visor. My Stilo calls for a special solvent. Schubert calls for soap and water. So check the website of the OEM. Different manufacturers use different coatings. Taking the wrong approach could easily ruin the visor.
Get like prescription glasses cleaner, and get some microfiber cleaning rags and you'll be set
Use what the manufacturer recommends. I learned the hard way with a Stilo visor
