How to wash the black dirt on the bottom of the pot?

Some woks often accumulate a layer of grease due to the backflow of oil and water left by pouring vegetables during cooking. After a period of time, it is hard and sticky, which not only affects the heat transfer effect of wok during cooking, wastes energy, but also easily makes kitchen tables and other places black and sloppy. Therefore, the oil at the bottom of the wok should be cleaned regularly. There are many ways to clean the oil dirt at the bottom of the pot, with convenience, quickness, good effect and no damage to the pot as the basic principle, and there is no need to stick to a certain method. When cooking porridge or stir-frying, the phenomenon of sticking to the bottom of the pot often occurs. If measures are not taken immediately to brush, it is difficult to clean the bottom of the pot, and it is easy to hurt the pot itself by scraping with hard objects. A more convenient way is to add some water to the pot, and the amount of water should not be too sticky. Then put the pot on a small fire and turn it off for a few minutes. After a while, the ingredients stuck to the bottom of the pot will be easily washed away. In fact, sticking to the pot can be avoided. For example, when cooking porridge, stir it frequently, and don't use too much fire. When cooking, once the pan is dry, add some water appropriately. The pot will turn brown when it sticks to the bottom to a certain extent. The blackened pot bottom is not only difficult to clean, but also difficult to scrape, otherwise it is easy to damage the pot bottom. In fact, it is not difficult to solve this problem, and we can borrow the wonderful use of vinegar. Put vinegar and water into the pot at the ratio of 1:2, and the height is better to cover the blackened part, then boil for 5 minutes, then cover and soak overnight. When I clean it up the next day, I just need to scrape it gently and it will all come down. For a raw wok, oil stains can be removed by burning backwards. Turn on the internal heat, turn it to the maximum heat, then turn the iron pot upside down on the flame, and stop the fire when the iron pot is slightly red. Scrape the grease off the bottom of the pot with a spatula, and it will soon fall off.
