Rub some Rubbing Alcohol on them with a cotton ball
A quick squirt of WD40 will fix it.

If you have just bought a guitar, the whammy bar will tend to not work off and on. If it is broken because of neglect or overuse, than yeah. Two possible reasons: First, if the whammy bar is pushed forward when the controller is turned on (possible because the guitar is laying on its face), the whammy bar will not work. There is a screen where you can calibrate the whammy and it will fix the problem. Or simply start over and turn on the controller again and be careful with the whammy. Second, I have seen a case where a small piece of plastic broke off the top of the whammy bar mechanism inside the guitar. If this is the case, you are pretty much out of luck unless you can locate an old wii guitar that can be used for parts.
