1, steel ball brush
The casserole is burnt and can be soaked for half an hour. After the burned position becomes soft, it can be easily wiped clean with a steel ball brush. Be careful not to use too much force when using steel balls, so as not to damage the enamel layer of the casserole, just wipe it gently.
Step 2 soak in vinegar
When the casserole is burnt, you can pour a small amount of white vinegar into the pot, add 10 times of water, boil over high fire, soak for more than two hours to soften the burnt skin, and then wipe the casserole with a scouring pad.
Step 3 burn with salt
Sprinkle salt evenly on the burnt place and heat it slowly with a small fire. It takes about 3 minutes to remove the burnt place with a shovel. To remove the burnt smell in the pot, you can choose to cook rice soup in a casserole. After the gap in the casserole is filled, the burnt smell in the casserole can be removed.
