Clean your computer mouse

If you have a mouse with a removable tracking ball, use a 50/50 vinegar-water solution to clean it. First, remove the ball from underneath the mouse by twisting off the cover over it. Use a cloth, dampened with the solution and wrung out, to wipe the ball clean and to remove fingerprints and dirt from the mouse itself. Then use a moistened cotton swab to clean out the gunk and debris from inside the ball chamber (let it dry a couple of hours before reinserting the ball).
