i am using a 2001fp. a kid was poking his fucking hands all over on the screen while i wasnt there. now it looks dirty. actually not that dirty cuz when the lcd is on, i dont notice any dirty mark. but when it is off and under light reflection i can see alot of fingerprint streaks on it. i tried water and isopropyl solution (from the LCD cleaner bought from staples) but it doesnt help. the streaks reappeared back right after the cleaning solution dried off. does anyone get this problem? could it be that the sweat has some kind of acid that was eating into the screen?
