Use a paint brush (about 1/2 inch wide) to brush out the ground coffee, then use a damp paper towel to clean up the fine powder. This method works very well, especially if you use a soft brush. Keep the brush near the grinder and brush out the grinder after each use.
Sweep a clean dry Popsicle stick around the where the blade built up a residue a few times and get your money's worth of coffee. That's where the oily flavor is. Then dump it in the brewing basket. Use the other hints above for a final more thorough cleaning. Go for the flavor first. :)
