My iron pot is old and brushed, and it is still black when it is clean, what s going on?

The black substances are coatings, high-temperature paints, silicones, graphite, etc., and I don't know exactly what they are. If you don't want to eat the coated black substance, rub it with gold steel sand, steel wool ball with dish soap, nano cotton and white vinegar, rub it with Nazhi rice cotton after boiling white vinegar, wash it, heat the pot to dry the water, pour a small half pot of cooking oil, shake it down, let the oil soak to the side, wipe it with paper on the side, heat, no need to smoke, heat it for a while and wait for the pot to eat enough oil, and then open the pot. If you don't coat it, you won't be able to wipe it black.

Smooth when coated, astringent when uncoated. I also wrote that there was no coating when I bought it, but in fact there was a coating, and the seller falsely advertised that the nitriding should be cyanid, which is definitely harmful to the human body, and if you don't want to eat a little coating every day, you will get rid of the coating.

This is the pot I used last night to rub off the coating with Nazhuan rice cotton, the pot has been opened, and a meal has been fried, after washing and drying, the paper is not black. I first rubbed this pot with steel wool balls, and then used gold steel sand, and then used steel wool balls, all of which were still black, and then used nano cotton and white vinegar, and then boiled with clean white vinegar, and then rubbed with nano cotton repeatedly after cooking, before the coating was removed, and it was not black. It turned out to be pitch black and bright, because there was always black engine oil when brushing the pot, and there were black things precipitating out of the hot pot, so I couldn't bear it, and I would rather rub the pot through and rub off the coating, and finally rub it off and it was not black.

Your genus is not necessarily good, not as good as seventy or eighty uncoated, I bought this more than a hundred is very rubbish, there is a coating pretending to be uncoated, the uncoated is gray, and the black must be coated!

**If it's too big, it won't be uploaded. After removing the coating, wash the pot every time you finish frying (no need to use steel wool, a soft pot brush), bake the water over low heat, wipe dry with paper on the side, pour oil directly next time you stir-fry, shake the pot, let the oil coat the pot, heat the pot, add vegetables, add an appropriate amount of water, don't let the pot smoke, the pot is not good for health, and the smell of smoke and water vapor is not the same. Recycling can be, after no coating, the pot has no strange smell, not black, when there is a coating, the pot has a strange smell of iron cyanide, and the draft is serious, after no coating, the smell is very light, and not much draft.

The iron pot is still black after washing and wiping because the iron on the surface of the iron pot is oxidized, and a layer of black oxide will appear, and the iron on the surface of the iron pot is difficult to wipe clean thoroughly.

How to maintain the iron pot.

It is recommended to dry it and put it in a dry and ventilated place to avoid rust caused by residual water stains on the pot.

Once it is found that the iron pot is burned, it is necessary to deal with it in time to prevent the burnt part from becoming more and more serious and difficult to deal with in the future.

Pay attention not to use too much firepower, a long time of high temperature will make the temperature concentration of the place damaged, rusty and black.

The reason why the iron pot is still black when it is washed and wiped is that the statement of the iron pot has been oxidized. After the iron pot is oxidized, it will slowly turn black when it comes into contact with the air, and a protective film will be formed to prevent the iron pot from further oxidation. Note that the next time you cook, you should wash the iron pot first to wash off the oxide on the surface.

The reason why the iron pot is still black when it is washed and wiped is that the surface of the iron pot is oxidized. After the iron pot is oxidized, it will slowly turn black when it comes into contact with the air, and a protective film will be formed to prevent the iron pot from oxidizing in a closed step. Note that the next time you cook, you should first wash the iron pot to remove the oxide on the surface.

Summary. The black substance that is wiped out by the washed iron pot with paper is the component produced after the oxidation of the iron pot, which generally has no effect, and has a certain effect, which can make the iron pot become a non-stick pan. When the pan is boiled, the high temperature allows the grease to melt, so that the grease will slowly penetrate into the pan and form a protective layer, so that the grease will make the pan not very sticky.

The iron pot can be soaked in hot water, so that it can be cleaned quickly, do not use a steel wool brush, it will damage the pot.

Hello, this is normal.

The black substance rubbed out of the washed iron pot with paper code is the component produced after the oxidation of the iron pot, which generally has no effect on the lead mu, and it also has a certain effect on the delay, which can make the iron pot become a non-stick pan. When the pan is boiled, the high temperature allows the grease to melt, so that the grease will slowly penetrate into the pan and form a protective layer, so that the grease will make the pan not very sticky. The iron pot can be soaked in hot water, so that it can be cleaned quickly, do not use a steel wool brush, it will damage the pot.

The iron pot is always rubbing out a black substance due to the following reasons:1Iron pot is not fully seasoned:

Newly purchased iron pans need to be seasonally treated before use to form a uniform oil film to protect the surface of the iron pan. If it is not treated with sufficient seasonality, a black substance may appear on the surface of the iron pan. Workaround:

Season process the new iron pot. Wash the pan with warm water and mild detergent, then apply a layer of cooking oil and place it in a preheated oven for seasonal treatment at the appropriate temperature and time. 2.

Food residue on the surface of the iron pan: After cooking food in the iron pan, food residue may adhere to the bottom of the pan and form a black substance. Workaround:

Wash the iron pot in time after cooking, you can use detergent and warm water to clean it, and use a soft brush or sponge to scrub the bottom of the pot. 3.Iron oxides on the surface of the iron pan:

When exposed to air for a long time, the iron pot will react with oxygen to form iron oxides, resulting in the appearance of black on the surface of the iron pot. Solution: Regularly care for and maintain the iron pot.

After use, wipe the surface of the iron pot with a paper towel or soft cloth and store it in a dry environment. A thin film of oil can be applied regularly to protect the surface of the pan and prevent the formation of iron oxides. Please note that the black color of the iron pan is not necessarily a problem, it is due to the characteristics and usage of the iron pan.

However, if you are upset or concerned about black matter, it is best to consult professional kitchenware maintenance advice or seek professional advice.
