Use a cloth designed to clean the TFT peak of a laptop or go to a camera shop for a lens cloth. It dose'nt hurt to humidify it slightly. A raw cotton cloth for eyeglasses can be a moment or two abrasive. You could even wet some tissue and wipe it clean next "breathe" on the screen and wipe near a polishing cloth that has not be used but washed previously use.
