My trackball, a Logi Ergo, has an issue with static friction. So I remove the ball and clean the ball, rollers, and laser eye. Helps for a while. Then I did all that and waxed the ball, which was even better but only as long as it lasted.
Today I did all that and lubricated the ball with genuine A-1 Nose Grease. Works like a champ. Turns out the ball is supposed to use skin oils.
So...
If you ever see me rolling my ball around on my nose, you know why.
