Q:
A: Use either dedicated screen wipes (from any PC shop etc), or a soft damp cloth such as a duster. You should not really need to use anything else unless you have managed to spill or stain the screen with something such as a splashed drink. Never use any strong detergents or bleaches etc, and if you do use any solution never spray it or apply it directly to the screen. Do not apply too much pressure on an LCD/flatscreen.
