Through normal use, a mouse will accumulate dust, lint, and oils on vital operational parts. For a mouse that uses a ball, the internal rollers will become dirty. For an optical mouse, the optical lens and possibly the LED lens will become dirty. This will cause performance to slowly degrade. If the mouse pointer begins to move erratically or the mouse itself no longer moves smoothly, the mouse probably only needs to be cleaned.
The rollers may have hair or lint wrapped around the axle points, carefully remove any lint with tweezers.
Look in the center of the roller to see if there is any built-up residue.
This can be easily dislodged with a pair of tweezers. A cotton swab with a drop of rubbing alcohol can be used to get the roller completely grime-free.
Once you are sure the rollers are completely clean and that there is no more lint, hair, or grime in the roller ball cavity, put the mouse ball back in and put the ring back on.
Turn the ring clockwise until it clicks into place.
Clean the Optical Mouse
Turn the mouse over and check the lenses for dust and debris.
With a dry cotton swab, clean the lenses.
Clean the mouse pads or feet if needed so that the mouse slides as smoothly as possible.
Test mouse and cursor movement.
Clean the Roller Ball and Roller Cavity on the Mechanical Mouse.
On the bottom of the mouse is a ring that circles the ball. Twist the ring counter-clockwise (to the left) and remove it.
With your hand under the ring and ball, flip the mouse back over.
The ring and ball will fall out into your hand.
Look inside the roller ball cavity and blow out hair or lint collected on the rollers.
There are generally one small white roller and two long black rollers that are perpendicular to each other. The rollers may have hair or lint wrapped around the axle points.
Carefully remove additional lint, hair, or other build up on the rollers with tweezers.
Using cotton swabs and alcohol, gently clean the rollers and any other affected surfaces in the roller ball cavity until the cotton swab comes away clean.
Clean the ball by blowing any lint off it and gently wiping it with a lint-free cloth.
Wipe the ball down with a clean lint-free cloth dabbed in alcohol.
Wait about five minutes for the ball and the roller cavity to dry.
Put the mouse ball back in and put the ring back on.
Turn the ring clockwise until it clicks into place.
Clean the mouse pads or feet if needed so the mouse slides as smoothly as possible.
Mouse Pad Maintenance
Keeping your mouse pad as clean and dust-free as possible will slow down the build-up process. Plastic mouse pads are better than the cloth ones as the cloth mouse pads trap oil and coat the ball with oil and lint. In addition, optical mice may not operate properly on some surfaces. For more information on optical mice surfaces, refer to the Dell KB Article: What surfaces should I use with my optical mouse.
