How do you clean the scroll wheel on the Fuze?

The best solution that I have found is CRC QD Electronic Contact Cleaner. Does not bother plastic at all Walmart Has it in the auto depertment. It is excellent for MAF sensors too, if you cant get your ride to idle right. Sometimes you can spray it in the seam beside the wheel and let it run in, then work the wheel real good. If your wheel is sticky, you may have a sugar base in there, like someone else said. If thats the case take it apart and clean very carefully with Q-Tip and Hot Water, followed by the QD cleaner.
