The next time one of your students has difficulty using a mouse, consider the possibility that the mouse might need to be cleaned. Mice can quickly become clogged with dust and dirt and stop working properly. Because this can be extremely frustrating for the students, it's a good idea to clean your mice on a regular basis. Here are some instructions to help you do this.
- Turn the mouse on its back.
- Twist the ball cover on the mouse until the cover unlocks and then remove the mouse ball.
- Inside the mouse are three rollers. Two of the rollers are at right angles to each other and only rotate. If either of these rollers are wobbly then the mouse may be broken and need to be replace. The third roller is narrower and spring-loaded. This third roller will give slightly when you press it.
- Dirt can be removed from the rollers by carefully scraping them with your fingernail or a piece of firm paper. The end of a plastic top from a pen works well also. Make sure the dirt doesn't fall into the mouse and be careful not to scratch the rollers. You will have to rotate the rollers and continue scraping.
- You may also need to pull out lint from around the ends of the rollers and clean the mouse ball itself.
- While you're cleaning your mouse, you should also clean the mouse pad. Shake it out or wipe it if it is plastic. Make sure to dry the mouse pad well. Never use liquids or cleaners in or near your mouse or computer.
