Before taking any more drastic measures, you should try simply cleaning a misbehaving scrollball from outside the mouse.

Before you continue, turn off the mouse using the slide switch underneath the mouse.
  • Before you continue, turn off the mouse using the slide switch underneath the mouse.

  • Before disassembling the mouse, first try scrubbing the mouse ball with a toothbrush and isopropyl alcohol. Be sure to get the bristles between the ball and the housing as this will help remove dirt and dust that is clogging the rollers inside.

  • You can also try blowing into the "ball hole" with a can of compressed air.

In order to clean perfectly the scrollball, you can hold the mouse upside down, and roll very quickly the scrollball on a white A4 papersheet (As if you wanted to colour the papersheet with the scrollball). Normally, you'll see some grey stripe of dust on the paper sheet!

Wow - Ludal's advice actually worked! I'm amazed. Paper -- just a plain sheet of paper.

Just to say it, the alcohol worked perfectly. Presumably, most people do not have isopropyl alcohol laying around so the paper trick is preferred—i.e., do not use rubbing alcohol.

Paper trick works perfectly. Last time cleaning a ball on the mouse is when the ball is under the mouse, not on top.
