I too have been plagued by the dirty trackball on the Apple Wireless Mighty Mouse. Although I love the mouse, cleaning the trackball as per Apple's instructions had done nothing. I have found a simple way to remove the lint/dirt etc... from inside the trackball WITHOUT disassembly of the mouse!

First, clean the mouse and trackball as according to Apple's instructions.

Next, take a piece of bright white paper, turn the mouse upside down on it, firmly press down on the ball, and vigorously run the mouse quickly up and down, left and right, AND in circles over the paper. After a while (it took me about 1-2 minutes), the lint and dirt that's been building up will break free of the sensors and when you take the mouse off the paper, you'll see everything that you cleaned on the paper -- and the scroll ball will work just like new.

I finished by cleaning it again with a damp, lent-free cloth.

Let me know how this works for you!
