For this to work, you will need to take your pan through a process of heating and cooling. You put it on the stove, start the heat and apply a thin layer of fat on it, with a napkin or brush. This will open up the pours of the pan. As the fat becomes to burn and the pan heats even more, place it on a lower setting on another part of the stove and continue to apply fat. This process repairs the pan, as it pushes the rust away from the pores, so you will have a stronger pan in the end. This will also make the bottom not stick to food, which you can test by cooking something in it.
