Original article title: Use this brush to wash the bowl, and be careful that the more you wash it, the dirtier it gets!

Before the text of today's article gradually begins, let's tell a little scary story.

One Sunday, Aunt Zhang, who lives in Chaoyang District, Beijing, had a sumptuous lunch for the whole family. Unexpectedly, that night, relatives suddenly vomited and diarrhea gradually.

and the culprit is actually a worthless towel. To be precise, after Aunt Zhang scrubbed the fish with a towel, she wiped the towel gourd and made it into a cold dish. The pathogen on the towel immediately entered the abdomen of the family.

It was reported in a variety show of Life Early Reference by CCTV in 2111, and the title of the article was "A rag, the whole family was poisoned".

Many years ago, there were no other reasons for the food poisoning incident, but the authoritative experts did pay special attention to one point:

The towels used in people's daily life were much dirtier than expected.

how dirty is the cloth in the dining room kitchen?

In general, there are two kinds of cloth in the dining room and kitchen at home: those that clean the cupboard and the dishes.

however, no matter which one, it is exposed to waste water, vegetable oil and food residues for a long time. Such a piece of cloth containing nutrients, suitable environmental humidity and porous materials is really an amusement park for microbial strains.

You are likely to say, small stalls, outdoor, sanitary conditions have not improved. Then let's take a look at the military logistics management canteen.

There is no doubt that the natural environment and management methods of the military canteen are very strict, and even the difference between raw and cooked towels was made in the early 1991s.

However, in a statistical analysis of environmental pollution of towels in a cooked vegetable area, the over-standard rates of bacteria and Escherichia coli both exceeded 81%.

The condition of cleaning towels is no better.

There was a scientific research on the environmental sanitation of Shanghai residents' dining room kitchens. Among 311 household cleaning towels, 17.3% of the samples had more than 2,411 Escherichia coli of 111 cubic centimeters, and the environmental pollution rate of kitchen utensils such as bowls and plates was immediately related to the environmental pollution status of cleaning towels.

In addition, in many cases of microbial food poisoning, the same germs were detected in the cleaning towel, which is inseparable.

which?

are so many germs still alive?

Don't be anxious. The good news is that most microbial strains can live in harmony with people.

Some germs are also essential for physical and mental health, such as Bifidobacterium and Lactobacillus. What makes people sick is a small number of pathogenic bacteria.

but there are two bad news. First: it is difficult to remove pathogenic bacteria, and the detergent can't be washed clean.

Many people don't care about the cleaning of the cleaning utensils themselves. After washing the bowl, squeeze the foam plastic and fill it with water. But the detergent only has stains, not germs, and the germs left in the cleaning towel will continue to breed again.

If the cleaning towel is soaked in turbid water again, overnight, the bacteria on it will already be able to match the total number of people on the earth. In the study of restaurant kitchen hygiene mentioned above, more than 95% of households wash towels every day, but 48.3% of towels still contain environmental pollution caused by Escherichia coli.

second: a towel is rubbed around, but you can't remember to throw it.

when unpacking new towels, I always think very well: this one washes the bowl, this one cleans the kitchen stove, and that one cleans the chopping board. But it's not the case when you use it specifically. If you are impatient, even the water on the ground will be wiped with a cleaning towel. _ As a result, pathogenic bacteria fled around with towels, which eventually led to the deterioration of the kitchen environment of all restaurants.

not to mention the older generation, you must never throw things away before they are worn out. -

in the long run, a towel containing old oil and sediment from hot pot, with a complicated taste and full of germs, is thus cultivated.

It's disgusting!

what should I do with the towel?

_

Special-purpose cloth

Those who brush bowls are those who clean cabinets and countertops. Try to distinguish them, such as using different colors or hanging them on different hooks. When it is necessary to wipe off the moisture on the ingredients, it is suggested to use kitchen paper, and it is best to test according to the touch of food.

There is a way to choose materials

There is a very useful article called kitchen paper, which looks a bit like kitchen paper and turns into a piece of cloth when it is watered. Strong water absorption, clean as soon as it is wiped, and the most important thing is to throw it away after use, so there is no need to worry about the secondary pollution problem of microbial strains.

If you don't accept the daily throwing, you can try it. This kind of towel has very good cleaning power and certain antibacterial ability.

the cleaning power is good because the superfine fiber is really fine, so it is larger than the surface and can quickly waste water. At the same time, microfiber itself is not a water-absorbent raw material, so water can't penetrate into chemical fibers, towels are very easy to dry, and germs can't survive in the natural environment.

The last thing to recommend is to wait for other cleaning towels made of porous structural materials. Although it has good water absorption, it is very easy to leave food residue in the porosity, and if it is not cleaned, it will become a happy house for bacteria to eat.

Daily maintenance

Besides washing oil stains with detergent, drying and airing, towels should also be disinfected and sterilized. Disinfectant can generally be used at 84, or boiled at 15 minutes _, which can also have the effect of sterilization.

the most important thing is to remember to replace it immediately. Don't say it's too dirty to wash out. Even if the towel looks neat, it's best to change it every 1~3 months.

When I saw this, some basin friends threw out doubts to everyone:

In fact, if you choose the right towel, laminated glass and furniture can be polished spotless easily; Some towels don't need to be rubbed by hand, but they can be washed clean and tidy by washing.
