When you wash your face in cold water you cause the pores of your skin to open. Washing eggs in cold water is like that. Cold water causes the pores in the shell to open and any bacteria on the outside of the egg is drawn down into the inside. That's the reason for using warm water.
You shouldn't let the eggs sit in water and soap shouldn't be neceassary. If I get an egg so dirty that a little rinse under warm water won't clean it, I don't eat it the dog does.
