Thanks for the guide! I was able to clean the scroll wheel properly and fixed the annoying inaccurate scroll issue.

Finally my mouse-wheel has stopped ghost scrolling, I used to have this problem where when I scrolled down and up it would go the opposite direction, at first I thought it was a bug but turns out on my other wired logitech mouse, it worked normally.

Upon following this instruction manual (A++) I managed to put some WD40 in the mouse wheel scrolling part, from the inside (not the wheel but the thing it’s attached to) and scrolled it a couple of times, now it works normally :)

Thanks to the author!

Thanks, cleaning up my M331 and put nachi tape on right-mouse-button so it works again (after it deform slightly).
