Apple's official polishing cloth is intended to clean displays safely and effectively, and it is explicitly compatible with numerous iPhone, iPad and MacBook Pro models which Apple has included in a long compatibility list for its microfiber cloth.

Selling a cloth that likely costs less than $1 to make and is probably the same as many other, similar cloths for $19. Amazing. I realize that it's the whole point of a company to make money, but there's making money, and there's ripping off your customers. Even if this cloth is somehow special, and using a normal microfiber cloth that is meant for cleaning relatively delicate things like lenses and displays would scratch the screens on Apple devices, what does that say about the fragility of those devices?
