Using the tip of the nail pick on a pair of clippers, clean underneath your fingernails to remove dirt and other built-up grime. Do this in the bathroom, under good lighting, so you'll be able to see your nails clearly.  In general, it's easier to clean the dirt from underneath your nails before you wash your hands instead of after. The drier the better. Avoid using a pencil to clean them out, as the lead may cause them to look dirtier.
