How to Keep Computer Clean
Keeping computers clean inside and out is a vital part of a maintenance program. Dirt can cause problems with the physical operation of fans, buttons, and other mechanical components. On electrical components, an excessive buildup of dust will act like an insulator and trap the heat. This insulation will impair the ability of heat sinks and cooling fans to keep components cool, causing chips and circuits to overheat and fail.
When compressed air is used to clean inside the computer, the air should be blown around the components with a minimum distance of four inches from the nozzle. The power supply and the fan should be cleaned from the back of the case.
Before cleaning any device, turn it off and unplug the device from the power source.
Clean the Computer Case
Clean computer cases and the outside of monitors with a mild cleaning solution on a damp, lint-free cloth. Mix one drop of dish washing liquid with four ounces of water to create the cleaning solution. If any water drips inside the case, allow enough time for the liquid to dry before powering on the computer.
Clean the LCD Screens
Do not use ammoniated glass cleaners or any other solution on an LCD screen, unless the cleaner is specifically designed for the purpose. Harsh chemicals will damage the coating on the screen. There is no glass protecting these screens, so be gentle when cleaning them and do not press firmly on the screen.
Use a dry, soft, lint-free cloth, preferably the micro-fiber cleaning cloth that may have come with your TV or monitor. Use a solution of mild soap and water, if needed. Don't spray a liquid directly on the screen. Don't use your fingernail or a sharp object to remove stubborn stains.
If a dry cloth doesn't remove the smudges and stains on your screen, then get yourself two cloths and a solution of diluted dish soap and warm water.
After removing any dust from your screen with a dry cloth, dip the other cloth in your dish soap solution, wring it out, and gently wipe your display. Next, rinse out your soapy cloth, wring it out again, and wipe your display to remove any soap residue. Finally, take your dry cloth and wipe the display to remove any streaking.
Clean the CRT monitors
To clean the screens of CRT monitors, dampen a soft, clean, lint-free cloth with distilled water and wipe the screen from top to bottom. Then use a soft, dry cloth to wipe the screen and remove any streaking after you have cleaned the monitor.
Clean the dusty components
Clean dusty components with a can of compressed air. Compressed air does not cause electrostatic buildup on components. Make sure that you are in a well-ventilated area before blowing the dust out of the computer. A best practice is to wear a dust mask to make sure that you do not breathe in the dust particles.
Blow out the dust using short bursts from the can. Never tip the can or use the compressed air can upside down. Do not allow the fan blades to spin from the force of the compressed air. Hold the fan in place. Fan motors can be ruined from spinning when the motor is not turned on.
Clean the Component Contacts
Clean the contacts on components with isopropyl alcohol. Do not use rubbing alcohol. Rubbing alcohol contains impurities that can damage contacts. Make sure that the contacts do not collect any lint from the cloth or cotton swab. Blow any lint off the contacts with compressed air before reinstallation.
Clean the Keyboard
Clean a desktop keyboard with compressed air or a small, hand-held vacuum cleaner with a brush attachment.
[warning]Never use a standard vacuum cleaner inside a computer case. The plastic parts of the vacuum cleaner can build up static electricity and discharge to the components. Use only a vacuum approved for electronic components.[/warning]
Clean the Mouse
Use glass cleaner and a soft cloth to clean the outside of the mouse. Do not spray glass cleaner directly on the mouse. If leaning a ball mouse, you can remove the ball and clean it with glass cleaner and a soft cloth. Wipe the rollers clean inside the mouse with the same cloth. Do not spray any liquids inside the mouse.
