My cast iron cooking grids are rusty. What should I do?
Your grids may rust if they have not been properly seasoned or maintained. Follow these steps to remove the rust and re-season your grids.
With the lid open, turn the control knobs to the MEDIUM HIGH position. Close the lid and wait ten minutes. This will help burn off excess food debris and oils. Then, open the lid and turn the control knobs to the off position. Clean your grids by removing any excess food and oils using a stainless steel barbecue grill brush.
NOTE: We recommend using only a stainless steel brush for cleaning your grids. The stainless steel bristles are durable and are the most effective for cleaning food particles from your grids quickly and easily.
Spread a thin coating of cooking oil over entire surface of the cast iron grids with a basting brush or oil mister. Be certain the entire surface, including all corners, have been coated thoroughly.
NOTE: We recommend you use vegetable, olive, canola, sunflower oil or vegetable shortening. DO NOT use salted fat such as margarine or butter. They burn off at a really low heat and will not protect the grids.
Storing Your Cast Iron Grids:
When your barbecue grill is not in use for long periods of time, store your cast iron grids in a dry warm place. Coating clean, dry cooking grids with cooking oil (at room temperature) will create an extra layer of protection against rust.
