How do I maintain and clean the LCD screen on my Dell™ portable computer or flat panel monitor?
Discussion
A common cause for marks on a portable LCD is oil and dirt deposited on the keys of the keyboard that can get pressed against the LCD when carried in a carrying case or when pressure is applied to the lid.
Cleaning
There are many cleaning solutions sold specifically as LCD cleaners. You can use these to clean LCD screens on Dell notebooks or Dell flat panel monitors. If you do not use one of these products designated specifically as an LCD cleanser, use isopropyl alcohol (IPA), which you can find in the grocery store, or water (preferably filtered).
NOTICE:
Do not use any of the following chemicals or any solutions that contain them: acetone, ethyl alcohol, toluene, ethyl acid, ammonia, or methyl chloride. If you have a different chemical or solution and are not sure whether it is suitable, do not use it. Using any of the chemicals in the previous list may cause permanent damage to the LCD. Some commercial window cleaners contain ammonia and are therefore unacceptable.
To clean the LCD display, use a soft, clean cloth (such as a lens cloth used to clean eyeglasses). Moisten the cloth with the cleaner, and then stroke the cloth across the display in one direction, moving from the top of the display to the bottom.
