yeah... you could get like a special cloth... but i wouldnt bother, just dont use sandpaper
i use a towel and some multi-purpose cleaner. not to sure if thats good for it. probably best to use a tissue. just damp. you dont want water dripping anywhere.
actually. get a tube of sillicon stuff... and fill up the entire back bit of it. so no water will get into the electronics. and then put a seal(spelling?) around the edge of the screen. then send it though the car wash. perfectly clean screen.
