Scrolling wheel is stuck

Recently I have been having some major trouble with my scrolling wheel I’ve tried all of the tactics that others have used but none seem to be working for me. And I have a refurbished Sansa Fuze so I can’t return it, what should I do? Are their any other methods to clean underneath the scrolling wheel? 

What have you tried so far?  And please elaborate on the condition of the wheel (difficulty turning, any noises, etc).
