Optical mice have largely replaced the mechanical ball mice that once dominated American homes and offices. These modern mice are more sensitive and can operate on just about any kind of surface. Another advantage is that there is no internal cleaning required, whereas mechanical ball mice were like miniature vacuum cleaners, picking up all the dust and debris on your desk. The maintenance is much easier with optical mice. Here are some cleaning tips from Professional Marketing International to help you keep them running smooth. 

While optical mice don’t pick up as much dust as mechanical ball mice, they still get dirty over time, sometimes resulting in erratic cursor control. To remedy this problem, first disconnect your mouse from the back of your computer. Turn the mouse over and examine the pads on the bottom. These are usually the first place that dust gathers. To clean the pads, you can use your fingernail or a penny to gently rub them clean. Never use a sharp or bladed object because they may permanently damage the pads. Another technique is to moisten the pads with water and then place the mouse on a sheet of paper. Pressing down with moderate pressure, drag the mouse across the paper. Repeat this 4-5 times to clean the pads. 

If it has been a long time since you last cleaned your mouse, it may require a more thorough cleaning than just the pads. After disconnecting it, dampen a cloth with rubbing alcohol and gently clean the entire exterior of the mouse. Use particular care around the sensor area. If the sensor appears to be dirty, it can be cleaned with a plain cotton swab. Caring for your mouse in this way helps to keep it running smooth. If you continue to clean it whenever necessary, your optical mouse will give you years of excellent performance. A clean mouse is truly a happy mouse.
