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
unfortunately… I don’t think you can. You might be able to get some 90% IPA (use a fresh bottle. IPA absorbs water from ambient humidity.) and q tips and get it ‘okay-ish’ for now, but the rotary encoder is generally pretty heavily enclosed (precisely because of this issue.) Flooding the thing with IPA or, submerging it… is not a good idea. I wouldn’t recommend trying it unless you were willing to buy another mouse when it makes things worse.
Ifixit does have a guide for replacing them, you maybe be able to take it apart enough to clean it out more thoroughly.
