A privacy screen, also called a privacy filter, is placed over a computer monitor, making any image on the screen visible only to the person in front of the computer. Anyone sitting to the side of the monitor will see either a distorted or blurred picture, or just a plain, black screen. Privacy panels come in matte or glossy finishes. You can also buy a more expensive LCD filter.
Dust the screen gently with a nonabrasive, lint-free cloth. This will remove surface dust and fingerprints. You can do this with any kind of privacy screen.
Wipe the filter with antistatic cleaning wipes every few days. This will prevent dust buildup.
Spray a gentle cleaning product, such as a vinegar and water solution, directly onto a soft cleaning cloth. Only use this method when you need to clean stubborn smudges or greasy fingerprints. Spraying the solution directly onto the screen won't cause damage, but it could drip into the tiny gaps that frame the screen as well as onto your keyboard.
