A sharp blade sounds like a terrible idea: the surface of the sensor needs to be optically flat, the sensor needs to SEE the surface it’s used on… I wouldn’t trust myself not to scratch it with a sharp object.

I’ve never needed to clean one but others have suggested using a q-tip with isopropyl alcohol to clean it.

You may also wanna clean the glide pads (The rounded shiny parts at the top and bottom) so the mouse glides like new and doesn’t “catch” on the table.
