Can't say I have perfect solution, but I use plain window cleaner. Works great, but use it sparingly lest you get spray in the electronics. In fact, spray it in a cloth and then wipe the screen
I think a more important question is the cloth you clean it with. Paper towels are abrasive and leave mico scratches. A cotton handkerchief would be better
