How can I clean my mouse wheel without taking apart my mouse?

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
