What can I do about mouse 'lint'?
Solution 1:
Clean the area frequently, and have a clean area to work with.
If you're cleaning your mousing area with a paper towel or a wet wipe, try to make sure you're cleaning with a lint free cloth, or you'll probably just add more stuff to the area.
Solution 2:
The gooey part of the lint is mostly dead skin cells so there's not much you can do to avoid it. Try washing your hands before using the mouse and using a smooth plastic mouse pad instead of a cloth faced one.
