water may streak though, there are cleaning products designed for fps. Most of them are 99% alcohol so it evaperates quickly. For the laptops and fps I have here at work I use ClearView Gel made by ALLSOP. It was like 5 bucks for 5 oz of it and it came with a little squirt bottle. I have had for 3-4 months and haven't even used an oz of it yet. You only need lilke a dime sized squirt to clean a very dirty screen.
Yeah, a little bit of water, maybe just a touch of soap and scrub lighly, don't wanna damage the darn thing. Works with me sis's flatscreen laptop just fine.
