Stainless steel pot is easily stained with black dirt, which is difficult to scrub. Now just add water to the bigger pot at home, put some pineapple peels, put all the smaller pots in, cook for 20 minutes, and then take them out when they are cool, and everything will be as bright as new! The burnt scale at the bottom of the pot can be wiped with rosin water, toothpaste powder, toothbrush or cabbage cloth, all of which have good results. The braised pork was accidentally burnt, and there was a thick layer of burnt meat at the bottom of the pot, which could not be washed off and was difficult to scrape off. What should I do? Pour one-third of any kind of vinegar (white vinegar or fruit vinegar ... cheap) into the pot, add two-thirds of water (be sure to cover the black part), cover it, cook for five minutes, soak it overnight, and gently scrape off the black bottom with a cream knife or spoon. Give it a try! How to maintain stainless steel pot: 1. Due to the low thermal conductivity of stainless steel, slow heat dissipation at the bottom and easy concentration of temperature, it is not advisable to use too much firepower when using stainless steel cookware, and the heating surface at the bottom should be as wide and uniform as possible, which can not only save fuel but also avoid burning food at the bottom of the pot. 2. If there is food sticking and burning at the bottom of the pot, you can soak it in water and gently scrape it with bamboo chips and sawdust, instead of using sharp tools such as kitchen knives; Wipe it with a soft cloth after cleaning and put it in a dry place. 3. Cookware should avoid colliding with sharp and hard objects to avoid scratches and dents, which will affect the appearance and sealing performance. 4. After the cooker is used for a period of time, a layer of fog will appear on the surface of stainless steel, which will make the surface of the cooker black. At this time, a soft cloth can be dipped in detergent or wiped with detergent to restore brightness. This method can also be used if its outer surface is blackened by smoke. 5. When using stainless steel pot, don't let the bottom of the pot have water stains. Especially when it is used in a coal stove, because the briquette contains sulfur, it will produce sulfur dioxide and sulfur trioxide when burning, and sulfurous acid and sulfuric acid will be produced when it meets water, which will corrode the bottom of the pot. Stainless steel tableware, like other metal tableware, tends to turn black after heating. In order to avoid this reaction, it is very important to treat the surface of new tableware. Just apply a small amount of grease, such as peanut oil or animal oil, to the surface of tableware before use, and heat it with slow fire for a period of time when cooking food. After the surface of tableware is coated with an oily antioxidant film, it can be used normally according to your needs. If there is no dry pot, it will not turn black again. If the stainless steel tableware has turned black, if you want it to be as bright as before, you can use the commercially available "electroplating rust removal and brightening agent" for rust removal and brightening maintenance. "Rust removal and polishing agent for electroplating" is safe to use, does not damage the surface of the coating, and is non-toxic and tasteless.
