Can the stainless steel pot still be used when it is red?

The surface of stainless steel is oxidized, which has carcinogens and must be removed.

1. Add water to the larger pot at home, put some pineapple skins, put all the smaller stainless steel pot in it, cook for 20 minutes, and take it out when it is cold. Everything is as bright as new.

2. Hawthorn can go to the bottom of the pot. If the bottom of the pot is burnt when cooking or cooking, you can put some hawthorn in the pot and add a little cold water to boil it (don't burn it dry), and the bottom of the pot will be removed soon.

3, tomatoes should paste the bottom of the pot. A few tomatoes that are not very good will naturally fall off if they are cooked in a pot.

4, beer and white wine to paste the bottom of the pot. If you accidentally burn the pot when cooking, you can pour a little white wine and beer, mix a little water (the ratio is 1: 1: 0.5), and let it stand for 5 minutes to easily scrub the pot cover.

5, apple skin or pear skin should paste the bottom of the pot, add some water with apple skin or pear skin, and then clean it up.

6, oranges should paste the bottom of the pot, cut a few oranges and put them in the pot to cook, stuffy for one night, the paste will turn up the next day, it is easy to fish out.

7. Remove the scale from the pot, add water to boil it, then add a small amount of detergent, leave it for one night, and then scrub it off. You need a layer of oil after scrubbing.

Extended data:

Chemical oxidation coloring method: the color of the film is formed by chemical oxidation in a specific solution, including dichromate method, mixed sodium salt method, vulcanization method, acid oxidation method and alkali oxidation method. Generally speaking, INCO method is widely used, but in order to ensure the color consistency of a batch of products, reference electrodes must be used for control.

Electrochemical coloring method: the color of the film is formed by electrochemical oxidation in a specific solution. Ion deposition oxidation coloring chemical method: put stainless steel workpiece into vacuum coating machine for vacuum evaporation. For example, titanium-plated watchcases and watchbands are generally golden yellow. This method is suitable for mass product processing. Because of the large investment and high cost, small batch products are not cost-effective.

High temperature oxidation coloring method: the workpiece is immersed in a specific molten salt, and certain process parameters are maintained, so that the workpiece forms an oxide film with a certain thickness and presents various colors. Vapor pyrolysis coloring method: it is more complicated and less used in industry.
