Computer Cleaning Part. 2 of 5

Why clean computer screen and monitor?
Dirt, dust, fingerprints, wood chips—you name it, there is a lot of debris that can collect on your screen and on top of your monitor. On the screen these foreign particles and smears distort the image, making it difficult to read. They may even cause permanent damage to sensitive LCD and CRT screens. Collecting on top of the monitor, a layer of debris can clog the ventilation cooling ports and cause monitor overheating. In an extreme case an overheated monitor may start a fire.
The following instructions apply for cleaning regular (SVGA) monitor screens as well as LCD screens and CRT screens.
Before you begin, collect the following cleaning supplies:
Soft, lint-free cloth
Screen cleaner spray (read caution before cleaning monitor)
Compressed air and/or anti-static computer vacuum
Mild detergent solution or spray
How to clean your monitor and screen in six simple stepsSTEP 1: Unplug the power supply cord and cable from the back of the monitor and allow it to cool for at least 20 minutes.
STEP 2: Vacuum the outside of the monitor, particularly the cooling grooves, holes or slots in the top surface where heavy dust or other debris may have collected. If you don't have a vacuum, blow canned, or compressed air in short puffs at an angle to the monitor surface. The goal is to remove dust and dirt without letting anything fall into the ventilation holes.
STEP 3: Lightly dampen a cloth with a mild soap solution and wipe down the outside plastic portions of the computer monitor.
STEP 4: Clean the monitor cables and power cord while they are disconnected. Lightly dampen a cloth with mild soap solution and gently pull the cables and cords through the cloth. Too tight a grip may damage the cables. Dry the cables and power cords with a dry cloth.

STEP 5: Check the documentation or call the manufacturer to find out if your monitor screen has anti-glare, or other delicate coatings. If so, ask the manufacturer for cleaning instructions. If it does not have these special coatings you may spray a window cleaner unto a lint-free cloth and wipe it clean. Do not spray directly unto the screen. Chemicals may drip inside the monitor and damage it.
Absent manufacturer instructions, you can safely clean and protect all LCD, plasma, HDTV, flat screen, and CRT displays and monitors with a Klear Screen cleaning kit. Klear Screen is the only formula used, sold, or recommended by leading manufacturers such as Apple, Dell, Sony Vaio, HP/Compaq, Fujitsu, IBM, Panasonic, Samsung, Sharp, Toshiba, and ViewSonic.
STEP 6: For dusty or dirty manufacturing environments using a ShopShield™ computer monitor dust cover is recommended. The innovative ShopShield covers are breathable membranes that totally encase your computer or monitor to filter out dust and dirt, but at the same time allow clean, cool air to pass through. It is an economical way to allow you to keep your computer protected even while it is running.
