Make sure the monitor is turned off and the power cable is unplugged from the power outlet.
Never spray or pour any liquid directly onto the screen or case.
Handle the monitor with care, as a darker-colored monitor, if scuffed, may show marks more clearly than a lighter-colored monitor.
Cleaning the Screen
Wipe the screen with a clean, soft, lint-free cloth. This removes dust and other particles.
If the screen is still not clean, apply a small amount of non-ammonia, non-alcohol based glass cleaner onto a clean, soft, lint-free cloth; then wipe the screen.
Cleaning the Case
Use a soft, dry cloth.
If the case is still not clean, apply a small amount of non-ammonia, non-alcohol based, mild non-abrasive detergent onto a clean, soft, lint-free cloth, then wipe the surface.
