After the new oven is received, it should be baked in the air first. The purpose of baking in the air is to remove the antioxidant oil coated in the oven before leaving the factory. Adjust the temperature to 200, heat it up and down, and air it for 20 minutes. There is no need to put baking pans or other accessories. There will be smoke and odor during baking. This is normal. After baking in the air, wait for the oven to cool down, and use a slightly wet rag (do not use a rag with a lot of water) to occupy the detergent.
