Use a little salt with cooking olive oil or butter.

Also, Invest in a nice cast iron pan as well. You don't wash the inside of the cast iron with soap. You just clean with steel wool and after a while it is seasoned to the point that is naturally non-stick.

After you cook and clean with water you rub a little oil or similar natural lubricant to prevent rust and condition the non-stick cast iron surface. Also you can use forks, spoons and metal utensils and not damage the surface.
