Soak the casserole in water for 5-6 hours to make the casserole fully absorb water. Put the casserole soaked in water on the stove and heat it slowly with low fire to let the water in the casserole evaporate slowly. After the inside of the casserole is dried, heat it with medium fire, and the heating time should not be too long, usually about 15-20 minutes.
After turning off the fire, let the casserole naturally cool to room temperature. Take out the casserole and wash the inside and outside thoroughly with clear water. Detergents such as detergent can be used, but be careful not to scratch the surface of the casserole. Dry the clean casserole and start using it. It should be noted that when cooking, don't use too high a temperature to avoid cracking the casserole. In addition, the surface of the casserole will be rough after boiling, so don't scrub it with hard objects such as metal shovel to avoid scratching the surface and affecting the use effect.
