The newly developed stainless steel bowl in kindergarten must be the cleanest if it has not been opened! ?
As no one took care of the children, I went to the kindergarten summer school, and the kindergarten where 19 was located was about to officially start school. As a result, the kindergarten bought a batch of new kitchen utensils, and the children in the summer class got the stainless steel tableware just issued by the kindergarten in advance. Many parents may think that as long as they are new, there will be no big problems, so they only clean the stainless steel bowl a little, but they are not familiar with stainless steel pot and tableware, which will lead parents to be unable to check their baby's health at home.
Why do all these stainless steel pot pots and pans have black oil?
The residual black oil should be the stamping oil left in the production process of the mold factory. This kind of oil can improve the lubrication in the molding process and avoid the damage caused by excessive friction between the material and the mold.
In addition, it is also pointed out on the Internet that in the manufacturing process of stainless steel pot pots and pans, there is a process called polishing, which is to make the stainless steel surface smoother, so industrial black oil will be used.
However, no matter what reason it is necessary to use black oil in stainless steel manufacturing, it is because the factory did not do enough cleaning in the last step, which will lead to the residual black oil on stainless steel tableware or pots.
The darker you wash, the dirtier you wash? How to remove the black oil from stainless steel cookware and tableware?
New stainless steel tableware must have one more cleaning process! Some parents follow suit, only to find that no matter how they wash, they can't clean up and even get dirty. The following are several common methods to remove black oil on the Internet for your reference.
Method 1: Make oil from oil, and dissolve oil with oil.
Please prepare cooking oil and napkins, and then start wiping hard. After repeated wiping, there will be less and less black oil on the napkin, and finally no black oil can be wiped out.
Method 2: Dough oil absorption method
Please prepare flour and water, and the ratio is about 2: 1 (flour 2, water 1). When adding water to flour, you must add it slowly until the flour becomes dough and does not stick to your hands. At this time, you can wipe the stainless steel with dough and wipe out the black oil.
Method 3: Blanch the white vinegar with water.
Wash the pot or dish with detergent and melon cloth first, then fill it with water, then pour in a few spoonfuls of vinegar and simmer until it boils. Stainless steel pot is of poor quality, and black oil will come out.
What effect does eating stainless steel pot or black oil on tableware have on human body?
These black oils are organic solvents, which may cause damage to the brain and nerves, and contain carcinogens, which are harmful to the body. But as long as a balanced diet, plenty of water, enough sleep and more exercise are used to maintain the normal function of the body, most of the poisons in the body can be metabolized.
No matter whether the black oil on stainless steel can be excreted through human mechanism, I think that since black oil is a chemical substance, it can be avoided. After all, once the black oil is eaten, no one can guarantee that there will be no problems; Therefore, parents are advised that if they get or buy new stainless steel tableware and pots, they should thoroughly remove the black oil after returning home in order to eat with peace of mind!
