First, when the iron pot is bought back, the following points should be done to prevent the iron pot from rusting easily.
1, the newly bought wok is generally rough. Buying sandpaper or grinding wheel and soaking in water to polish the inner surface or edge of the wok will improve the unevenness of the wok surface, make the wok smoother, and make it difficult to hide evil and accommodate evil.
2. Soak the iron pot with rice washing water, because there are fine particles in the rice washing water, and the rice washing water is acidic, which is beneficial to the iron pot. Soak for about two or three hours, boil the rice washing water, and let the iron pot fully absorb the rice washing water before pouring it out.
3. Pour a little cooking oil into the iron pot and bring it to a boil. Then let the oil stay in various positions of the iron pot for a while, let the oil enter the gap of the iron pot, squeeze out the air in the gap of the iron pot, and fill the gap with clean grease, so as to avoid air oxidation and rust. Finally, pour off the oil and clean the wok.
Second, when using the iron pot at ordinary times, you should do the following to avoid the rust of the iron pot.
1, usually use the wok, clean the wok, and don't leave residue in the wok. In this way, the iron pot can avoid the danger of pollution and reduce losses.
2. There is water in the iron pan after cleaning, and the water drops should be dried or dried to avoid oxidation and rust due to contact with air.
3. Clean cooking oil can be used to wipe the surface, so that the oil can fill the gaps in the iron pan to prevent air from entering and cause rust.
Third, the iron pot that has not been used for a long time can be prevented from rusting by doing the following.
1. Clean the wok, make sure there is no dirty grease and vegetable residue in the wok, and wipe off the water drops.
2. Apply clean cooking oil to the inner surface of the iron pan, so that the whole inner surface of the iron pan is coated with a layer of grease. Then, clean the wok with a soft dry towel, and then dry or suck up the water droplets.
3. Seal the wok with a transparent plastic bag that can completely wrap the wok and put it in a ventilated and dry place.
Iron pots will always rust if they are not used for a long time. When not in use, the iron pan should be cleaned and maintained in advance and stored in a dry and ventilated place.
