You can use the canned air that they sell to blow the dust out of computer keyboards to blow the dust out of you knife. You should also be able to wash it in mild soap and water, maybe use a brush if needed to get into the crevices. Rinse it in the hottest water possible and it will dry quickly. WD-40 would probably be a good idea after such a cleaning. . . The "WD" stands for water displacement. It's not the greatest lubricant though, so follow up with some 3 in one oil or something like that on the blade pivot.
