    • Before you continue, turn off the mouse using the slide switch underneath the mouse.

    • Before disassembling the mouse, first try scrubbing the mouse ball with a toothbrush and isopropyl alcohol. Be sure to get the bristles between the ball and the housing as this will help remove dirt and dust that is clogging the rollers inside.

    • You can also try blowing into the "ball hole" with a can of compressed air.

In order to clean perfectly the scrollball, you can hold the mouse upside down, and roll very quickly the scrollball on a white A4 papersheet (As if you wanted to colour the papersheet with the scrollball). Normally, you'll see some grey stripe of dust on the paper sheet!

Wow - Ludal's advice actually worked! I'm amazed. Paper -- just a plain sheet of paper.

I can't believe I just found this post in 2015, gotta say thank you for saving $53 bucks!

I actually did both things but I used one of those wipes for eyeglasses which have alcohol in them after rubbing it on paper. Worked great.

Amazing, after months of frustration - rub for 5 mins on a plain sheet of paper - working perfectly. Thanks
