Step 2: Add two-thirds of cold water to the casserole, grab a handful of tea leaves and put the casserole on the gas stove to boil. Because tea has adsorption, it can remove the earthy smell and fireworks smell of casserole. Be sure to heat the casserole with a small fire first, so that the casserole has a process of slowly adapting to the temperature. Turn off the fire after boiling for three minutes, and remember to cover the lid. The odor on the lid can also be removed by the steam of tea leaves.
Step 3: Pour out the tea and rinse it with clean water after the temperature drops. Be sure to heat the water in the hot pot and add cold water to the cold pot to avoid cracking of the pot due to uneven heat conduction. Wash it and dry the outside.
Step 4: Pour two-thirds of the water into the casserole, and then put half a bowl of rice in it (leftover rice is also acceptable). Don't wash, start heating on low heat. Similarly, start cooking with low heat.
Step 5: When the rice porridge is sticky, pour some rice soup along the edge of the pot with a spoon to make the whole inner surface of the pot stick with rice soup. Because rice soup can effectively block trachoma, avoid water seepage and cracking in the future, and also prevent the pot from sticking to the pot during use.
Step 6: Pour out the rice soup and wash it, then dry the water on the surface, and you can use it. If you are not in a hurry to use the pot, you can wait until the rice porridge is cold and let the rice soup be fully filled with trachoma before pouring it out. The effect will be better.
After the above-mentioned boiler maintenance and normal use, the casserole will not crack and stick to the pot, and its service life will be longer.
