Methods/steps
Very thick paste rice crust can be scraped off with an iron scraper or a knife, and then scrubbed with scrubbing tools such as steel balls, so that the black paste can be completely removed. It should be noted that when scraping with tools, don't use too much force, and don't scrape blindly. Tools such as steel balls have a large stress area and are easy to hurt the paste. Otherwise, although it is cleaned, it will destroy the enamel of the casserole, causing water leakage and oil leakage, which is not worth the candle. Therefore, after careful scrubbing with powerful tools, if the paste marks cannot be completely removed, you can consider scrubbing with more flexible tools.
In order to prevent the metal scrubbing tools from damaging the enamel of the casserole, you can use items with good flexibility or moderate hardness to scrub the casserole. Fine sandpaper is the best scrubbing tool, which can scrub paste marks at fixed points. In addition, items with moderate hardness such as charcoal, bone charcoal and cuttlefish bone can also be used to scrub shallow paste marks.
For the bottom of the casserole for cooking porridge or cooking, the rice crust often sticks firmly to the bottom of the casserole, which is very laborious to scrape. You can cool the casserole first, pour out the porridge rice, wash all the rice grains that can be washed off with water, and then slowly heat them on the stove until the rice crust is about to emit black smoke. Be careful not to burn until the black paste gets worse. Finally, put the casserole down to cool for a while, and shovel it with a rice shovel while it is hot, which can often remove most of the rice paste.
If the rice crust is not badly burnt, but the paste layer is thick and sticky, you can still try to take it off completely and cook it. The specific methods are as follows: one is to make burnt rice porridge with water, which is not necessarily smooth and complete; Another method is to heat it with a small fire until black smoke comes out, then add vegetable oil to the pot to soak all the crispy rice, then stop the fire and let it cool. After cooling, you can shovel the crispy rice with a spatula, and then pour some tomato juice on the crispy rice, which is delicious.
For the paste marks caused by meat and other foods, if you are too lazy to spend time and energy scrubbing, or don't have suitable scrubbing tools, you can use dry burning method to paste: pour the food out of the pot, wash off all the food residues that can be washed off with clear water, then slowly dry burn the casserole on the stove until the rice crust is reduced to ashes, and finally shovel it off with a spatula, which can often remove the paste marks of the rice crust effortlessly. This method is more suitable for removing the paste marks in black or gray-black casserole.
Some stubborn sticky paste marks are difficult to clean with tools. In this case, you can soak and clean it with the treatment agent first, and then wash a part of the rice crust with tools. Generally, it can be washed with white vinegar and caustic soda. , or with other household strong acid or alkali cleaning agents, the washing time is preferably above 1 hour.
It should be noted that most casseroles contain heavy metals, even purple casseroles, which are known as healthy, safe and healthy pots, are no exception. Heavy metals such as lead can be separated from vinegar. Therefore, if the casserole is washed with white vinegar, it is best to discard the vinegar and rinse the pot with clear water.
In addition, for ordinary paste marks, as long as there is basically no carbonized layer, it can be removed by soil method. Use sour fruits such as carambola and sour lemon, or use dried bamboo shoots, put water in a casserole, and cook for about half an hour. Basically, you can paste it without scraping tools.
Some casseroles have very small pores, and the newly bought casseroles are burned directly without caulking. Often, the paste marks on the bottom of the pot are thoroughly scrubbed, but there is still a thick paste smell. This is because some food residues have penetrated into the micropores and burnt in the micropores, so the burnt smell will last for a long time. In this case, you can soak in white vinegar 10 minutes or so, and then cook the rice noodle paste in a casserole. After the rice paste is cooked, take it down, spread it in a pot, let it stand and cool, and then clean it. The paste smell is removed, and there will be no such paste smell that can't be washed out in the future.
