The newly purchased stainless steel pot has only been used twice, and a circle pattern like a rainbow appears on the bottom of the pot

There is no problem with oxidation after heating. My stainless steel pot is just like this Is the rainbow color on the bottom toxic?

200 series stainless steel will be shoddy during use, leaving many hidden dangers in production and daily application. For example, the nickel content of some brands of 200 series stainless steel products is only about 1%, and the chromium content is reduced in order to achieve non-magnetic properties. This variety not only has poor corrosion resistance and is easy to rust, but also easily produces manganese vapor during the welding process, which is harmful to human health. Similarly, if it is used to heat food up to a certain temperature, manganese will also harm human health. What damage will the rainbow color on the bottom of the stainless steel pot do to the pot?

Generally, the rainbow color is caused by It is caused by overheating of metal alloys or heating for a long time. Most of the stainless steel pots we use at home contain a variety of alloys. Each of these alloys has its own characteristics. Some are resistant to high temperatures, some are anti-corrosion, and some have a stabilizing effect. (Most of them appear rainbow-colored, often accompanied by slight deformation.) However, the heavy metal content of the alloy is within the range specified by the country, and its use will not actually cause harm. Use it with confidence, the only thing you need to pay attention to is that the next time the pot itself is heated, the temperature should not be too high, or use the induction cooker as little as possible or choose a thicker pot. Hope this helps. View original post >> Is the rainbow pattern on the bottom of the stainless steel pot harmful to the body? I have cooked crabs in the stainless steel pot for a while, or I found rainbow colors on the bottom of the pot after making soup. Is this considered rotten

This is the pot overheating The surface oxidation that occurs does not matter.

Stainless steel products made by regular manufacturers use food-grade stainless steel with extremely low lead and chromium content, so if your pot is produced by a regular manufacturer, you don’t have to worry.

In addition, chromium is released due to a chemical reaction that occurs only with acids and alkalis, but not at high temperatures. Why does the newly purchased stainless steel pot get mushy as soon as I use it?

Because it is pure steel and has no coating... I have a Zwilling pot at home and the same thing... Take white vinegar and 100% of it. Wipe it with a clean cloth, it should be able to be wiped off (while the pot is hot)...

I just bought a Midea electric pressure cooker and after using it for the second time, two spots of paint fell off the bottom of the stainless steel pot, which was black. I really get angry

How to use the new stainless steel pot I bought after changing the pot

Just use it directly. When I boil the water in the new electric pot that sells pots, there are circles of black on the bottom of the pot

A new pot should be powered on and heated with hot water, then scrubbed repeatedly with dish soap to remove surface impurities and powder before it can be used normally! Black stains on the bottom of stainless steel pot

1. Brush the pot

1. Just soak it in hot water. It can be easily cleaned. Never use steel wool brush. Scrubbing will damage the pot. If it is an aluminum pot that is scrubbed and then used for cooking, it will be very bad for the body. (If you must brush, you can use coarse cloth instead of steel wool)

2. Shanlihong can remove the scorch on the bottom of the pot

If the bottom of the pot is scorched when cooking or cooking, you can remove it Put a few Shanlihong in a pot, add a little cold water and bring to a boil (don't boil it dry), and the paste at the bottom of the pot will be removed soon.

3. Remove the tomato paste from the bottom of the pot

If a few tomatoes that are not very good are cooked in the pot, they will naturally fall off.

4. Use beer and liquor to remove scorching on the bottom of the pot

If the pot is accidentally scorched while cooking and there is crust on the bottom of the pot, if it is difficult to brush it off, you can pour a little liquor and beer into it. Mix it with a small amount of water (ratio 1:1:0.5), cover it and leave it for 5 minutes, then it can be easily cleaned by brushing.

5. Remove apple or pear peel from the bottom of the pot

Add some water to boil the apple peel or pear peel, and then it will be easy to clean.

6. Remove the orange residue from the bottom of the pot.

Cut a few slices of oranges and put them in the pot. Boil them and let them simmer overnight. The residue will turn over the next day and it will be easy to remove. .

7. Used phone cards and magnetic cards are washed and paste pots

Description of the problem: Used-up phone cards, shopping cards, discount cards, and VIP cards are accumulating more and more, although some people like to collect them. This kind of thing, but most people are not so interested in it, so it is better to use it to do some practical things. It is inevitable that the pot will be scorched when cooking. If you use a hard shovel to clean the scorch, it will cause scratches. If you use a wooden shovel, it will be difficult to completely remove the scorch. Why not let those old cards reflect their use value again?

How to operate: Use a card along the edge of the pot to gradually scrape off the burnt scale. Note that you don’t need to use too much force when scraping. If the card is made of hard plastic, it can also be used to scrape dirt from the gas stove.

8. Add a little vinegar and heat water to boil it, then it can be washed away.

9. There is a trick that cannot be spread easily. In summer, pour a little rice into the pot and let it ferment naturally. After smelling the sour smell after 2 days, remove the ashes.

10. Dry-simmer over low heat for a while, sprinkle with salt when it smokes, shake for a minute, then turn off the heat, and then wipe it again. It will be very clean without leaving any residue or mushy smell. .

11. Use a cleaning ball and washing powder to directly wipe off the blackened part of the bottom of the pot.

12. Apply toothpaste, add some water with a cloth, and rub it hard. It is economical and does not damage the pot. However, it may take a little effort to wipe.

13. Use high-concentration hydrogen Soak in sodium oxide solution (for example, 100 grams of water, 50 grams of sodium hydroxide. Because it is highly corrosive, you must wear acid-resistant and alkali-resistant gloves and cannot be used to clean aluminum products), and then scrape with a steel ball.

If you can find "sodium percarbonate or sodium perborate", you can directly pour boiling water, then add perboron or percarbon, soak it until the water temperature is high, and then pour it away.

The former of the above two methods is to remove burnt grease, and the latter is to remove the burnt yellow color.

14. Remove the scorched scale from the pan

Add water to the pot and boil it, add a small amount of detergent, leave it overnight, then scrub it, and then it can be removed. After scrubbing it clean, apply a layer of oil.

15. Stainless steel pots are easy to stain with black dirt and are difficult to clean. Now you only need to add water to the larger pot at home, add some pineapple peels, and then put all the smaller pots in and boil for 20 seconds. Minutes, take them out when cold, and they will be as bright as new!

16. If metal utensils are rusty, wash them with salt and some lemon juice. This can quickly remove the rust and make the utensils shiny.

17. A clever way to remove dirt from aluminum pots

(1) Soak an appropriate amount of stone soda in wet water, and then wipe it with an eggshell dipped in alkaline water. The surface of the aluminum product will be wiped out in this way. Bright, fine and clean. When wiping, it is best to cover the eggshell with a piece of cloth to prevent your fingers from being scratched when the eggshell rubs.

(2) Dilute two tablespoons of detergent with half a cup of hot water, then wet the aluminum pot with a cloth, and then wipe it with water sandpaper.

(3) Boil 1 spoon of detergent, 2 spoons of washing powder, and half aluminum pot of water on the stove. After three to five minutes, put on a gauze glove and use a ball of wax on your hand. Use the iron wire to gently wipe the pot lid, and then wipe the aluminum pot.

(4) Place the pot in hot water and scrub it with poultry feathers. When rice is cooked in a hot pot, wipe the surface of the pot with old newspapers or a damp cloth to keep it bright and clean.

(5) If the rice is burnt and the paste mark is "imprinted" on the aluminum pot, you can use lightly burned and wet charcoal to scrub it. No matter how big or thick the burnt area is, it can be cleaned.

Circles of rainbow-like colors appear on the TV screen. What's wrong? < /p>
