If the rust is more stubborn, you may need a chemical rust remover. You can find these products at most hardware stores. Follow the instructions on the packaging carefully, always wear gloves and work in a well-ventilated area when using them.

Step 3: Washing With Dishwashing Soap and Water

Dishwashing soap is a mild detergent that will not damage the finish on your grill. Next, use a soft bristle brush to scrub the rust off of the grill bottom.

Spray the grill and let it sit for 10 minutes before scrubbing with a brush. Rinse with water and dry with a towel. Be careful not to get citric acid on the food. It is safe to use, but it will taste sour.
