Under normal circumstances, stainless steel will not rust. However, if it is not properly used or maintained, or the environment in which stainless steel is located is too harsh, stainless steel may rust. When we see yellow or orange rust spots on the steel surface, we can quickly confirm that this is a sign of rust.

1, to avoid food dyed black. When the new wok is cooked for the first time, the food will be dyed black. At this time, you can rub tofu residue in the pot a few times to avoid food pollution. It can also be refined with oil before formal use. Method: Pour in a proper amount of oil, turn off the fire until the oil is hot, turn the iron pan to make the oil stick to the pot wall, and wash it with clear water after the oil is cool.
2. Cleverly remove the fishy smell of the iron pot. After the fishy raw materials such as fish are cooked, the fishy smell in the pot is difficult to remove. At this time, you can put a little tea in the pot, add water to boil, and the taste will be removed.

3. Ingeniously remove the iron smell of the iron pot. When the new iron pot is used, it has an iron smell. There is a simple way to eliminate this iron smell: put a little sweet potato skin in the pot, leave it for a while, then pour it out, and then wash the pot, and the iron smell will be gone.
4. Cleverly remove oil stains from the wok. The frying pan has been used for a long time, and burnt oil stains have accumulated. It is also difficult to clean them with alkali or detergent. What should I do? As long as the fresh pear skin is put into the pot and boiled with water, the scale will easily fall off.
Rusting of iron products will react with oxygen. Generally, isolation method is adopted to prevent rust, that is, Batie is isolated from oxygen, such as iron railings coated with antirust paint, oil-coated iron pans, chrome-plated car wheels, etc. Other methods are also used in industry, such as sacrificial metal method, which connects iron with a more active metal to form a circuit to protect iron from oxidation and sacrifice that active metal.

Preventing iron from rusting is nothing more than taking corresponding precautions according to the internal factors and external environment in the process of iron rusting. Since the premise is that iron products are in power, it is impossible to prevent internal causes. Basically, it is aimed at the external environment, such as painting, coating and other isolation methods, to isolate the water and oxygen needed for rust, to prevent the electrochemical reaction of salts and accelerate oxidation. It can also effectively avoid impurities on the iron surface if it is placed in a ventilated and dry environment.
