I read somewhere that iron and steel expand at a microscopic level, when heated, such that you can fill these small holes up with oil and get a non stick cooking surface.
Whenever I’ve washed up an iron pan I always put it back on the heat with some oil. You can literally see the water bubbling out of the surface as the pan gets hot and the water boils off.
