How to Season Rusted Cast Iron Grates

Cast iron grates are featured on many ranges and stoves. The grates cover the burners that cook the food. Grates are also found in indoor and outdoor grills. Cast iron is popular for grilling because it helps to cook food evenly. Because they are made of iron, these grates can rust very quickly. Seasoning cast iron is one way to keep them rust-free. Regular cleaning and seasoning of the grates helps keep them in top condition.

Things You'll Need

• Dishwashing liquid
• Scrub brush or pad
• Paper towels
• Cooking oil
• Aluminum foil

Instructions

1. Remove the grates and place them in the sink. Fill the sink with warm water, add dishwashing liquid and clean the grates thoroughly with a scrub brush or pad (steel wool also works well). Make certain all traces of food are gone. Rinse and dry grates with paper towels.

2. Apply a very thin coat of cooking oil to the grates with a paper towel. Cover all areas of the grate with the oil.

3. Place a large sheet of aluminum foil on the lower rack of the oven.

4. Heat the oven to 250 to 300 degrees Fahrenheit.

5. Place the grates on the top rack of the oven.

6. Leave the grates in the oven for one hour, suggests Mother Earth News.

7. Turn off heat and let grates cool.

8. Replace the grates to the stove or grill.

Tips & Warnings
