Then you need to clean the rollers, which is nowhere near as easy, and
in my experience, almost always involves dismantling the mouse. I was
very glad when I got rid of my last rollerball mouse and went over to
the optical scanning ones. A quick spray of furniture polish on the base
occasionally to make them slide more easily and clean the clag off the
window and you're done.
I just hate to throw out something that serves my purpose adequately as
this ball mouse does.
