http://www.klearscreen.com/ works well, ANY computer store, Compusa, CCity, even Staples or Office Max should have them.... Make 150% sure its for LCD first!!!!!!!
Do not use Windex. I also just read a mixed solution of ispropyl alcohol and water (50% each), but I have no experience with that.

For the kids...
