Your monitor only needs occasional cleaning. When cleaning,
unplug the main power cord. Dust with a clean soft cloth, or, if the
cabinet is soiled, you can use a slightly damp clean cloth soaked in
mild detergent. The screen may be cleaned with household window
cleaning products, but avoid using alcohol based solutions or
strong acids and bases.
