Pro Display XR users can have their screens customized with a nano-texture glass, which gives less glare and reflectivity for a thousand dollars. But cleaning it is an entirely different method altogether, one that uses a special cloth from Apple.
In a support document released by the company, the nano-texture glass may only be cleaned with a dry polishing cloth issued by Apple. Furthermore, liquids, water and other cloths may not be used to clean the display.
Apple recommends contacting Apple Support if in case you lose your dry polishing cloth so they can send you a new one. The document doesn’t say if there’s a charge for the replacement cloth.
As for the dry cloth itself, Apple says that it may be washed with water and dish soap and left to dry for 24 hours at a minimum. The standard Pro XDR display may be cleaned using a damp microfiber cloth.
