Wikipedia:Featured picture candidates/unwashed hand

 
An example of how minuscule particles can be caught between dermal ridges in the hand, yet remain unseen by the naked eye. Washing one's hands removes such contaminants.
Reason
I think it has great detail. The small dirt particles make this an excellent addition to the hand washing article, illustrating how small particles can be hidden from the unaided eye. In thumb version of the picture, the dirt particles are uncontainable and the hand looks clean. One does not notice them until the image is enlarged.
