Even if you never touch the screen of your monitor, it somehow has a tendency to collect dirt, dust, and fingerprints. Here are instructions on how to clean it.
When cleaning any computer componet (this includes the monitor) the standard advice is do not spray any liquid on the component and do not use so much liquid on the cloth that it runs off the cloth. Instead dampen a cloth with the liquid and then wipe the component with the damp cloth. The reason for this is that the liquid could seep inside of the case through cracks or vents and short out or ruin the electrical circuitry. As added protection against this happening, you should unplug the component before cleaning and not plug it in until any liquid that may seep inside has a chance to dry (like overnight).
If you clean the screen when it is off, you will be able to see the dirt and smudges better.
