I clean mine up with a angle grinder with a wire brush attachment. Works out real well. Then wipe it down with a dry rag, then one with some vegetable oil. After that, melt ya some lard an brush on, put in the oven at bout 350* fer couple hours, then out ta the grill on high heat fer a couple more, shut the grill down then just let it set till mornin. Now it is usable. Don't wash out with soap. Wipe out after each use an coat with vegetable oil to prevent the rust from formin again.
