G9 mouse scrollwheel problemo

My old g9 that I have for 2-3 years is having a bit of a problem with scrolling. I noticed is getting kind of stuck like its grinding on something. Is it hard to take apart the mouse and put it back together? I suspect the scroll wheel itself is rusting and may need some good olde sanding. I appreciate some pointers to fix it.

If your mouse has a rubber ball, you can normally release it by rotating a locking ring that holds it in place. Look for an arrow telling you which way to push or twist the locking ring. Remove the ball and carefully clean it with a lint-free cloth or soap and water. Dry it carefully. While in the case of optical mouse, clean occasionally with distilled rubbing alcohol and a paper towel. This type of mouse stays clean longer.

Lol, I dont have a ball mouse.
