One of the most common questions I am asked, now that LCDs are in wide use, is how to clean one.� Every manufacturer has their recommended method.� What Envision recommends will ruin an NEC LCD and void your warranty.� As you will be able to tell every LCD needs to be cleaned in a different way.� Another thing I learned from finding all this information is that every manufacturer has the same warning: Never touch or press on the LCD screen with your fingers - NEVER!!!� Doing so can cause the pixels to short out and die.� Then you will have blank spots on your LCD.
Here is the cleaning information I have gathered from various manufacturer's web sites.� The text is taken verbatim from the manufacturer�s web sites, �read-me� files, PDFs and e-mails.
List of manufacturers:
I called CTX tech support and was told the way to clean their LCDs was in the Technical Glossary and General FAQ.� I asked the guy to check that out and he said he couldn�t find it either.� He said to use very mild soap, tepid or lukewarm water and a just slightly moist lint-free cloth.� This is supposed to be added to their General FAQ.
I received an e-mail in response to a web based tech support request.

To clean the screen:
1. Shut down the PC.
2. Turn off and unplug the display
3. Gently dust the screen with a dry, soft, line-free cloth.� [Webster: I think they meant lint-free]

distilled water.� Make sure the LCD panel is completely dry before you turn
the display back on.
4. Plug in the display.
5. Turn on your PC and display.
To clean the screen:
1. Turn off the monitor and remove the power plug (pull the plug, not the cable)

Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass cleaner.
