Computer Mouse Cleaning

Optical or laser mouse

Why? A dirty optical or laser mouse can cause the mouse cursor to be difficult to move or move erratically.

Procedure Use a can of compressed air that is designed for use with electronic equipment, spraying around the optical sensor on the bottom of the mouse. Blowing air on the bottom of the mouse clears away any dirt, dust, hair, or other obstructions that may be blocking the optical sensor.

Avoid using any cleaning chemicals or wiping a cloth directly on the optical sensor, as it could scratch or damage the optical sensor.

Optical-mechanical mouse (ball mouse)

Why? A dirty optical-mechanical mouse (mouse with a ball) can cause the mouse to be difficult to move, as well as cause strange mouse movement.

Procedure: To clean the rollers of an optical-mechanical mouse, you must first remove the bottom cover of the mouse. To do this, examine the bottom of the mouse to see what direction to rotate the cover. As you can see in the below illustration, the mouse cover must be moved counterclockwise. Place two fingers on the mouse cover, push down and rotate in the direction of the arrows.

Rotate bottom of mouse cover

Once the cover has rotated about an inch, rotate the mouse into its normal position, covering the bottom of the mouse with one hand. The bottom should then fall off, including the mouse ball. If the cover does not fall off, try shaking the mouse gently.

Once the bottom cover and the ball is removed, three rollers should be visible inside the mouse. Use a cotton swab, finger, or fingernail to remove any substances on the rollers. Usually, there is a small line of hair and dirt in the middle of the roller. Remove as much of this substance as possible.

Once you have removed as much dirt and hair as possible, set the ball back in the mouse and place the cover back on.

If the mouse still has the same problems, repeat the above process. If, after several attempts the mouse is still having the same problems, your mouse has other hardware issues and should be

replaced.

Note

Cleaning your mouse pad with a damp cloth can also help improve a computer's mouse movement.

All types of mice

Why? To help keep the mouse clean and germ-free.

Procedure: Use a cloth moistened with rubbing alcohol or warm water and rub the surface of the mouse and each of its buttons.
