Clean the nano-texture glass
To remove dust or smudges from the nano-texture glass screen, use only the polishing cloth that came with your Studio Display, Pro Display XDR, or iMac.
For infrequent cleaning of hard-to-remove smudges, you can moisten the cloth with a 70-percent isopropyl alcohol (IPA) solution.
Never use any other cloth to clean the nano-texture glass. If you lose the included cloth, you can order a replacement polishing cloth.
