Fix for Mighty Mouse Scrolling Problem

If your Mighty Mouse stops scrolling smoothly - here is some helpful information from MacFixit:

"Apple's Mighty Mouse, despite its unique features, still uses a mechanical ball that is used for the navigation. Just like previous ball mice, this mechanism is prone to skip after a while of usage...

"The roller ball in the mouse is largely inaccessible, unlike old ball-mice where the ball could be removed by opening a hatch. Users could then apply alcohol cleaners to the roller mechanisms. For the Mighty Mouse, the ball will need to be cleaned in-place. Apple recommends taking a lint-free cloth and lightly moistening it to clean the surface of the mouse as well as the mouse enclosure. If the mouse has a noticeable piece of dirt that can be felt in the mechanism, users are recommended to turn the mouse upside down and roll the ball against the cloth rapidly until the dirt dislodges.

"Apple has a quicktime movie of the process available here.

"In addition to the steps suggested by Apple, users might try cleaning the ball with some over-the-counter isopropanol, which should help in clearing away finger grime that might have built up on the ball. Using a cloth or Q-tip, users can lightly moisten the ball with isopropanol (just enough to moisten, and not drip onto the ball) and roll it around with a clean cloth until the alcohol dries up. This step may need to be repeated several times depending on how dirty the surface is. If too much alcohol is used, allow it to dry (with the aid of an air canister if available) before using the mouse again.

"Other users have found that the easiest way to dislodge dirt is to lay a piece of paper on a table or other flat surface to provide a slight friction surface, and then turn the mouse upside down and roll the ball rapidly around on the paper. This allows for more rapid movement of the ball than just using a cloth around one's finger. In addition, if users do this on a counter or glass surface they can try soaking the paper in isopropanol so it will run up into the roller mechanism during the rapid rolling action."
