That may work for some, but for me it is the opoposite. If my fingers are too dry (I tend to have very dry skin) I need to add a little oil or just a lick of my finger in order to get the wheel to respond better. Yes, I have the latest firmware.
So if the above cleaning does not work for you, try the opposite - add a bit of moisture to your finger.

"I noticed that the latest firmware seemed to make navigation with the click wheel more precise and less sluggish. Additionally I suppose (not sure though) that the technology behind a click wheel is similar to that behind the laptops' touchpads or trackpads. Advices like those below work for me:

*Carefully clean finger oils and dirt from your laptop's touchpad with a damp cloth; you can also add a small amount - less than 50 percent of the solution - of isopropyl alcohol.
Touchpads are sealed, so you probably don't have to worry about a touchpad problem developing because of dirt or dust. Touchpads can become slippery or sticky from the transfer of oils or other substances from the fingers of those troublesome humans who use them, though")
