IMO, Gojo and Dwipes (Dwipes actually contain Aloe Vera, a plant that absorbs Lead from the ground!) are just regular anionic surfactant soaps. Great for dissolving dirt, but Lead is not dirt, and it doesnt act like dirt. Microscopic amounts stick to skin through an electromagnetic charge that creates a bond to skin. Uranium is easier to clean off than Lead! The CDC recomends using Hygenall, which I found at Galls.com. Its called Hygenall FieldWipes (they dont have it on their website for some reason). What is great about the Hygenall stuff is that you dont have to rinse.
