The specific operation method is as follows:

1. Remove the oven grill. Soak them in a water tank filled with hot water and a few drops of detergent.

2. Make cleaning solution. Add 4 tablespoons (56.7 grams) of baking soda to a 1 liter spray bottle and fill it with water. Shake the spray bottle to dissolve baking soda.

3. Spray on the oven. Spray several times in oily areas.

4. Clean the oven again with a solution of half water and half vinegar. The inner wall of your oven should be clean by now.

5. Clean the oven rack. Scrub the oven rack with soapy water. Wash off the soap, dry it and put it back in the oven.
