Cleaning Computers

Computers vary in operating systems, memory capacity, and software, but all share similar types of hardware and accessories. If the cursor on your computer screen suddenly stops moving smoothly, the mouse may need cleaning. Disconnect the mouse's cord from the computer. On the back of the mouse, remove the housing that covers the ball. This may involve unscrewing two small screws, rotating the housing or pushing it forward. Remove the ball. Wipe it clean with a lint-free cloth dampened with isopropyl alcohol. Blow any dust and lint out of the ball socket. Clean the two rollers inside the mouse. You may need to use a toothpick to remove chunks of grease and hair. With a cotton bud dipped in  wipe the rollers clean. Allow the parts to dry, then reassemble and reconnect the mouse.

Even if you have an optical mouse, its underneath must be cleaned occasionally. One way to prevent build-up of grime in the mouse is to keep the mousepad as dust-free and clean as possible.

Clean and service the keyboard only when the computer is off. Every month or so, wipe the keys and the area around them with a dampened lint-free cloth. If keys stick or you start getting characters on your screen that you did not type, clean the keyboard interior. To do this, unplug the keyboard, remove the screws from the bottom, and carefully pry the housing apart. If it is does not come apart easily, you may have missed a screw, or you may need to press locking tabs. Then turn the unit upside down, and carefully shake out any debris. Use a vacuum cleaner's blower with a narrow extension attachment to blow debris fro beneath the keys.

 If there is sticky grime in the machine, use lots of cotton swabs soaked in water or alcohol to clean it away; this may take time. Once dry, reassemble the keyboard and turn the computer back on.

If you spill liquid on the keyboard, unplug it immediately and set it upside down on towel to allow the liquid to drain out. Let the keyboard dry completely before attempting to use it again. If you spilled cold drinks or some other liquid that gets sticky when it dries, you will probably need to clan the inside of the keyboard.

       Use a soft cloth and clean the monitor screen. Spray a small amount of cleaner on the cloth, and then wipe the screen. Do not spray cleaner directly onto the screen. Vacuum the ventilation slots on the monitor's top and back periodically.
