Shortly after Apple announced he new MacBook Pro lineup and the other new products yesterday, one less notable product made it into the store, a polishing cloth. The speculation is that it isn’t always clear on what kind of cloth to use, Apple does make that information in its support documents, but the best way is probably to use the official cloth from Apple.

The “Polishing Cloth” is £19 in the UK and $19 in the US and is made from what Apple calls a soft, nonabrasive material” and it can be used to clean any Apple display, including the nano-texture display Apple offers.
