Let the porridge cooked in the casserole stand for 40 minutes, pour it out, and then wipe the casserole clean with a sponge. Never use anything too hard to brush the pot, because the casserole is physically anti-sticky. For example, using too hard steel balls will affect the non-stick effect of casserole.
Then clean the casserole, dry the internal and external moisture with a dry towel or kitchen paper, and the casserole is finished. The casserole treated in this way is not only not easy to crack, but also not easy to stick to the pot.
