Used this guide to clean my scroll wheel, took me 15 min, super easy. Didn’t need to remove anything, just opened it up and disconnected the 1 ribbon cable from the top half.
I used some clear tap folded on itself and ran it through the scroll wheel a few times. Only a bit of dust came out but the difference is crazy, its totally free spinning now.
Stop convincing yourself your scroll wheel is fine, open it up, clean it out and its even better.
Thanks iFixit
