Clean Studio Display
If your Apple Studio Display has nano-texture glass, clean it only using the included polishing cloth. See the Apple Support article How to clean the nano-texture glass on your Apple display. For additional cloths, visit apple.com, your local Apple Store, or other resellers.
Note: For infrequent cleaning of hard-to-remove substances on nano-texture glass or standard glass, you can use a 70% Isopropyl Alcohol (IPA) solution.
If your Studio Display has standard glass, clean it using a microfiber cloth lightly dampened with water.
