I noticed that my mouse wheel when scrolling up would sometimes scroll down instead (and vice versa). I figured it’s probably because there is some dirt and grime inside the mouse wheel casing that’s somehow interfering with the sensor.
How can I clean it without taking the mouse apart? I guess I could fill it with some isopropyl alcohol and wait a bit to shake it out or something but I don’t know how well that would work and I don’t want to make it worse obviously.
Does anyone have a better idea maybe? It’s a Logitech G703 Lightspeed
Not old enough, apparently. They originally were two wheels, and even when they switched to the ball, there was actually still two smaller wheels inside which were turned by the ball.
