What is Baked On Oil Finish (BooF)?

Raw cast iron will initially turn from silver to an orange rust as the exterior weathering oxidation begins. A stable oxide exterior patina eventually forms, which results in the dark brown appearance we normally see on old cast iron. But that natural rusting process may take 1-2 years. Our 15 step Baked on Oil Finish process pre-rusts the metal and initially provides a beautiful chocolate brown appearance – bypassing the initial orange rusting episode. Be aware, the grates will eventually develop brown rust (time dependent on location, amount of traffic and weather conditions). This is normal in the aging of cast iron.

If rusting grates are unacceptable in your installation, you may want to consider a plastic grate.
