【How to Avoid Rust?】(1) Make sure that you scrape your grates after each use; (2) Season them by brushing with oil after each use; (3) Leave the dampers open a bit so that condensation does not collect in the grill; (4) Put the lid back on your grill when it is not in use; (5) Cover the grill when it is not in use; (6) If you need to store your grill for a long period of time, heavily coat them in cooking oil, wrap them in a plastic bag and store in your covered grill
