Apple has its own cloth to clean the Pro Display XDR
Apples Pro Display XDR costs $5000 along and the stand costs $1000. But Apple says that you can use only the provided cloth to clean the pro display XDR, Since the display has high end nano texture glass.
However, it’s not clear what to do if you lose this included cloth or after the clothes usable life period. So if a customer loses the cloth they have to call Apple and let them send a new one for a cost. The expected cost of the cloth is about $100.
There are very strict rules on how to clean this cloth too. Apple says you should use dish soap and water, Then rinse and dry for 24 hours.
