We are all diligent in running our anti-virus scans, cleaning up old files and folders and removing old software. But, quite often, the physical cleanliness of the computer itself is forgotten. A dirty computer can make its use difficult and even cause hardware failure. By performing a few regular cleaning tasks, your computer will last longer and be easier to use. This is our second article discussing the best ways to clean your computer equipment and keep it running in top condition.

Monitor

There are two main types of computer monitors today: Each requires a different method of cleaning: The standard, or CRT, monitor and the Flat Panel, or LCD monitor. Please make sure you follow the cleaning correctly for each type. Normal cleaning should be done every three months. This will keep the display clean preventing additional eye strain. Smoking while using the computer will cause additional residue buildup on the display and will require cleaning more often. Note: Make sure the monitor is unplugged from both the computer and electrical source before starting the cleaning.

CRT
The CRT monitor is vary similar to a television in the components used. Cleaning requires a damp soapy rag or towel. A glass cleaner may be used on the display front. To clean the display, spray water or cleaner on a soft rag and wipe making sure to get completely around the edges of the glass. Be sure to put the water or cleaning solution on the cleaning rag and not directly on the monitor itself. Again, if you are a smoker this may require additional passes with a clean rag.

To clean the monitor case use a rag dampened with warm water. Make sure there is no excess water on the rag and be careful when cleaning around the air vents on the back and top of the monitor. Once clean, let the monitor air dry before reuse.

Warning: DO NOT attempt to open the monitor case while cleaning. CRT monitors use large capacitors while in operation which can hold a charge for two to three hours after being unplugged from the power source. If you feel the monitor needs additional service or cleaning, please take it to a trained service professional.

LCD
LCD, or flat panel monitors, should only be cleaned with warm soapy water. Cleaning solutions, especially those with alcohol will damage the display surface. There are special cleaning solutions available, but I have found the soapy water to work best. There are products on the market that claim to clean LCD monitors, however quite often these are false claims and can cause damage. To clean the monitor use the damp rag and wipe down both the display and case then let air dry before reuse.

Keyboard

The keyboard seems to always accumulate dust and particles down between the keys which cause a constant need for cleaning. All keyboards today have a plastic membrane under the keys which helps prevent dirt from getting inside.

Most dirt particles can be removed by merely turning the keyboard over and shaking vigorously. Then, using a damp rag clean the keys and case. Pressing on the keys to clean them will not cause damage as long as the keyboard is unplugged from the computer.

If the keys are extremely dirty or the keyboard has not been cleaned in a while, you can remove each key with a small standard screwdriver. Make sure you know where each key goes before removal so it can be returned to the proper position. Soak the keys in warm soapy water then rinse and dry before replacing.

Mouse and Mousepad

Like everything else, mice come in many shapes and sizes. There are only two basic types though: Ball type, which contain a small ball and wheels, and optical or laser type. Each mouse has different cleaning requirements.

Ball Mouse
A ball mouse works by having a ball rolling on a rough surface. This turns a series of wheels or rollers inside the mouse sensing direction and speed. Unfortunately, the ball can easily pick up dust and lint which builds up on the rollers.

Turn your mouse over and remove the round cover holding the mouse in place. This usually has finger grips and arrows for removal. Be careful not to let the ball fall on the floor. It can be difficult to replace if lost or damaged. Clean the ball using a warm wet cloth then set aside.

Look inside where the ball was and you will find two or three plastic wheels which sense the ball movement. This is where the dirt accumulates and can sometimes be difficult to clean. I have found that my fingernail or other small flat scraper works best. Slowly turn each wheel scrapping the lint off. This may take a while as the wheels are usually spring loaded and will move around as you clean them. When finished use your compressed air to blow out the dust and lint. If possible, use the small tube on the air can to get under the mouse buttons. Do not try and remove the buttons. They can easily be damaged.

Optical Mouse
Without the ball or internal wheels, the optical mouse is much easier to clean and maintain. On the bottom of the optical mouse is a small light and optical pickup. Use your compressed air to blow any dust and lint from the bottom of the mouse. Then take a cotton swab soaked with alcohol and clean each surface.

Mousepad
Hard surface mouse mousepads can be cleaned with warm soapy water and dried. Cloth surface mousepads do not clean as easily. If your mousepad does not have a rubber or foam backing, it can be washed in a clothes washing machine. Rubber and foam backed pads will not survive in the machine. Unfortunately, there is no easy way to clean these types of pads. (If you know of a good way please contact me)
