Get your supplies ready. All you will need is a soft, smooth, and clean cloth. Pour half-and-half water and isopropyl alcohol into an empty spray bottle and shake.
Turn off your LCD monitor. By this, I mean turning the screen off and unplugging any power source connected to it. This is not only a safety precaution from electrocution, but turning off the screen will also make it easier to see the dust.
Lightly spray the alcohol and water mixture onto the cloth. Do not soak the cloth and never spray directly on the screen.
Gently wipe the screen in one direction (i.e. from left to right and up to down).
Wait until the screen is dry.
Turn on the screen.
