1. Choose a stainless steel grill brush. The bristles of the stainless steel grill brush are soft enough to protect the surface of the grill. You can choose between a cylinder brush or a straight brush. Both brushes worked well, but the sides of the rack bars were easier to clean with a cylinder brush.

2. Heat the grill. Residual grease is easier to clean when it is softened by heat. Set the grill's temperature to the highest setting, then leave the stove on for 10 to 15 minutes, or allow the temperature to rise to between 260°C and 320°C. Next, turn off the grill.

3. Brush the grill. Start with the first metal strip of the rack and brush back and forth. Keep brushing until the grease and food residue are gone. Brush the rest of the grill in the same way.

4. Grease the grill with vegetable oil. Soak a towel in a container of vegetable oil so that it absorbs about 1 teaspoon of the oil. Next, wipe each metal strip with a towel between food tongs. This is done to prevent the grill from rusting.
Do not use more than 1 teaspoon of cooking oil. If there are unextinguished food scraps under the grill and the towel has absorbed too much oil, the oil can drip and cause the stove to burst into flames.
