Yes you are right, the anti-glare coating does not stand up too much punishment. Even the fat on human skin is enough to dissolve it, making stains that is impossible to remove. I have used some water on a piece of papper, then quickly wiped of with a dry piece of papper to clean my LCD. But I do not recommend this. The water leaves permanent marks on the screen. A piece of lint-free cloth, slightly moist, works best in cleaning the screen from dust and other particles that may have become slightly "stuck" on the surface. Just be careful to have the screen off, and do not apply much pressure at all, since that can damage the crystal elements in the screen, leavind dead or stuck pixels.
