It sucks when they stop registering properly, but there is something satisfying about cleaning that gunk out. I have a trackball mouse at work and I clean it every day or two to keep the ball rolling smoothly. It's gross, but I like sticking the tip of a pencil in there and pulling out small lumps of gunk. And it feels especially nice to give the ball a spin after.
