It may be just an excuse, but I rarely clean my desktop computer because I am not sure of the best way to do it. Do I need special products for the monitor and the keyboard? And what's the easiest way to clean a sticky mouse? I got the help I needed from Erik Sagerdahl, General Manager of Techs to Go, a Diamond Certified company. Mr. Sagerdahl recommends using a damp scratch-resistant cloth on the monitor. For the keyboard, try a product called Dust-Off, available at your local computer store, which blows dust off safely and effectively.
You'll probably have to replace the keyboard if something like soda or coffee is spilled into the keys. To clean a mouse, unscrew the cap that holds your mouse ball in place by turning it counter clockwise. Take the ball out and clean it, along with the three rollers inside, with a Q-Tip and rubbing alcohol.
