Question about Logitech M570
Does anyone know a good way to maintain the little balls on which the blue ball rolls? Mine have become quite scratchy after years and the trackball is constantly stuck.

Fat helps.... I always use normal Nivea cream.... so treat the blue ball with it, the others just clean normally.... helps for years;)
I take the ball out and clean it with cotton swabs.
I had the 15 years with the red ball over 3 generations (thumb ouch). All you had to do was press the ball hard and then turn it in one direction. That always loosened any dirt immediately and the ball rolled like it did on day one.
