I’m sure you know, water and oil don’t mix together very well. That’s because oils are non-polar molecules and water is polar. Polar molecules stick to other polar molecules, and non-polar molecules stick to non-polar molecules.

You don’t need to leave soap on your hands, but you do need to rub it all over your hands, in every crack and crevice, to ensure you’re washing everything off.
