How to Clean a Mouse

Computer mouse

Computer mice, including optical and ball mice, often need to be cleaned. Dirt, food and other substances can get on your mouse during use, especially on the bottom and buttons of the mouse. Grime on your mouse causes problems using the mouse. If you notice your pointer jumping or if it refuses to move on the screen, a dirty mouse may be to blame. Optical and ball mice must be cleaned differently, but neither process takes over ten minutes.

Things You'll Need

• Cotton swab
• Rubbing alcohol
• Paper towel or clean cloth

Instructions

Ball

1. Unplug your mouse from the computer. If your mouse is not connected via USB, turn off the computer before disconnecting the mouse.

2. Turn the mouse over.

3. Turn the circle surrounding the ball counter-clockwise to remove the circle

4. Remove the ball and clean with a damp cloth.

5. Use a cotton swab or a fingernail to clean the three rollers located underneath the ball inside the mouse. If you use a damp cotton swab, ensure no water drips from the swap into the mouse.

6. Dry any excess moisture from inside the mouse and from the ball.

7. Return the ball and circle. Turn the circle clockwise to return.

8. Reconnect the mouse to your computer.

Optical

1. Disconnect your mouse from your computer. Most optical mice are connected via USB. Unplug the connector from your computer to disconnect.

2. Dampen the end of a cotton swab with water or alcohol.

3. Wipe the LED lens gently with the tip of the cotton swab.

4. Dampen a paper towel or clean cloth and clean the top of the mouse, especially around the buttons. If any dirt is built up on the bottom of the mouse, use the paper towel or cloth to remove it.

5. Allow the mouse to dry completely before reconnecting it. This usually takes around two to three minutes.

Tips & Warnings

• If you use your mouse frequently, clean it at least once per month. If you work in a high dust environment, you may want to clean it weekly.

• Remove any excess water immediately. Water inside the mouse can cause damage.
