Hi friends, a year ago I bought an MX Master 3 mouse, and recently strange signs started to appear on it (which look like greasy ones) I use a computer for work purposes only and work in a clean environment. I was trying to clean it, it started peeling off parts of the plastic so I got off the idea. I've never seen anything like this with other mice I had. Does anyone have any idea how to clean it? Or is it possible to replace the top panel of the mouse? French Pictures Thanks!
