The black scale burned at the bottom of the casserole is formed by the carbonization of food residues and burnt substances at high temperatures during the use of the casserole. These black scales can be removed in the following ways:
Vinegar and water removal method: Mix vinegar and water together in a ratio of 1:2, then wipe the bottom of the casserole with a cloth dipped in vinegar water, and wipe it several times to remove black scale.
Soot removal method: After wetting the soot, wipe the black dirt on the bottom of the casserole with a cloth or paper towel moistened with the soot, or place the casserole on a tray with wet soot, wait for a period of time and rinse it with clean water.
Baking soda removal method: Mix baking soda and water into a paste, then apply it to the bottom of the casserole, wait for a while, and then gently brush off the black dirt with a brush.
Grapefruit peel or lemon peel removal method: Put the grapefruit peel or lemon peel into the casserole, add an appropriate amount of water, soak the black scale at the bottom of the casserole to soften after boiling, and then gently brush it off with a brush.
These methods are all effective in removing black dirt from the bottom of the casserole and giving the casserole a new look. The reason for using these methods is that black scale is formed by the carbonization of burnt food residues and oil stains at high temperatures, which is tightly bound to the surface of the casserole and is difficult to remove with ordinary cleaning methods. Substances such as vinegar, soot, baking soda, and grapefruit or lemon peel can chemically react with black scale, breaking it down or loosening it, making it easy to remove.
In addition to the above methods of removing black scale, in order to avoid the formation of black scale at the bottom of the casserole, you can apply a layer of oil or a layer of heat-resistant anti-stick pad to the bottom of the casserole before using the casserole, which can effectively prevent food residues and oil from adhering to the bottom of the casserole, so as to avoid the formation of black scale. In addition, it is also necessary to pay attention to controlling the temperature of the casserole to avoid food burning and oil carbonization caused by excessive temperature.
In conclusion, removing the black scale from the bottom of the casserole requires some specific methods and substances. Understanding the reasons and significance of these methods and substances not only helps to ensure that the use of casseroles is safe and hygienic, but also helps to improve the quality and health of people's daily lives. At the same time, it is also very necessary for some people who use casseroles frequently, knowing how to remove the black dirt from the bottom of the casserole.
