How to Clean an Optical Mouse
The optical mouse is gradually replacing the trackball mouse on most computers. While it requires less maintenance, it still can eventually build up dust and dirt making the mouse jerky or unresponsive. Clean your optical mouse to prevent it from stalling on you.
Turn off your computer and unplug the mouse.
Look at the lens on the bottom of the optical mouse. If you see any debris, blow it off, or take a Q-tip and rubbing alcohol and lightly clean the lens.
Look at the small rubber pads on the bottom of the mouse. Dust and dirt tends to build up here. Scrape as much of the gunk off as you can with a paper towel.
Wipe any remaining dirt and dust off the pads of the optical mouse with a damp cloth.
Plug the mouse back into the computer, and enjoy your newly cleaned optical mouse.
