If I ask you
Where is the dirtiest place in the house?
Many people’s first reaction is: toilet, toilet!
But actually
The refrigerators, washing machines we use every day…
Use it over the years
If the interior is not cleaned in time
Probably dirtier than a toilet!

The refrigerator has a “refrigerated and frozen” Dafa body protector, which is regarded by many people as a “safe” for food, stuffing everything inside.
As everyone knows, the refrigerator may have been mutinous in secret and “co-contaminated” with pathogenic bacteria.
See if this is your refrigerator?
A foreign survey of 200 household refrigerators found:
Microbial contamination is more serious on objects such as refrigerator shelves, vegetable frames, and rags used to wipe the refrigerator.
Among them, 59.5% of refrigerators detected Listeria monocytogenes, and 32.5% of refrigerators detected Salmonella [1].
Domestic research has also found that the microbial contamination of household refrigerators is serious. Staphylococcus, Escherichia coli and other microorganisms have been detected [2]. Even in the freezer, the bacteria cannot be “frozen to death”. .
If you eat these foods contaminated with pathogenic bacteria, you may suffer from abdominal pain, nausea, nausea, vomiting and diarrhea, and even life-threatening.
Refrigerator “dirty” hardest hit:
1. Glass compartment for refrigerator
2. Freezer drawer
3. Refrigerator drain
4. Refrigerator door seal
It is very important to clean and disinfect regularly. It is recommended to perform a thorough cleaning once a month.
How to clean your refrigerator:
1. Before thorough cleaning, remove all food and power off.
2. Use a clean rag dipped in detergent water or medical alcohol, wipe the glass compartment and the inner wall of the refrigerator compartment in all directions, and then clean it with a clean wet rag and dry it (this step is easy).
3. The freezer drawer needs to be cleaned out, carefully cleaned with detergent, rinsed with clean water and then dried (pay attention to the installation order of the drawer, do not confuse it).
4. The drain is a small hole on the inner wall of the refrigerator, which can be dredged with a small stick.
5. The refrigerator door seal is a place that many people will ignore. When cleaning, you can wrap a paper towel or rag with a fork, moisten it with medical alcohol, and wipe along the inside of the seal .
Remember, how long did the water dispenser work at home? Did you care if it was dirty?

Studies have shown that the inner tank of the water dispenser, the smart seat (the connecting component between the barrel and the body) and other parts, if not cleaned and disinfected for a long time, it is easy to breed a large number of microorganisms and pollute the drinking water [ 9].

In addition, in the process of changing the water, if you do not wash your hands, it is easy to contaminate the barrel mouth, smart seat and other parts. It is easy to form scale if it is not cleaned for a long time…
This kind of water dispenser itself is unsanitary, and drinking a bucket of water for ten days or eight days has cultivated a lot of bacteria and viruses, and it is not unreasonable for diseases to enter from the mouth!

The next point is, how to clean the water dispenser?
1. For the fuselage, dampen a clean cloth with medical alcohol to clean the water outlet, sink and water dispenser housing.

2. For the smart seat, you can take it off and use a clean damp cloth to dampen medical alcohol for cleaning and disinfection.

3. For the inner tank, dilute the special water dispenser disinfectant in proportion according to the instructions and pour it into the inner tank, and let it stand for about 20 minutes (different disinfectants may vary), Then open all the drains of the water dispenser, drain the water, and rinse the water dispenser liner with clean water from the smart seat until there is no smell of disinfectant.

The washing machine helps people wash clothes every day. It should be very clean, right? But have you ever seen what a washing machine looks like when it’s taken apart?
(Source: Internet)
Ouch~~~ Let me vomit for a while! The toilet is cleaner than this!
The total number of bacteria in washing machines exceeds the standard rate of 81.3%, the detection rate of total coliform bacteria is 100%, and the detection rate of mold exceeds 60.2% [4].
If you use such a washing machine, it is easy to cause secondary pollution to your clothes. Wearing such contaminated clothing can easily lead to skin diseases such as itching, rash, and even gynecological diseases [3].
Then how to properly clean the washing machine?
Washer cleaning method:
1. Daily cleaning: After the washing machine is used up, open the lid to ventilate, clean the inner barrel, seal the sealing ring, and clean the filter bag, which can reduce the pollution of the washing machine to a certain extent [4]. In addition, for washing machines with self-cleaning function or antibacterial function, it is necessary to ensure that the self-cleaning function is normal (most of them need to add detergent according to the instructions).

2. Regular and thorough cleaning: Regularly use a special washing machine cleaner with antibacterial and decontamination function to clean the washing machine. The advantage is that it can be operated without disassembling the washing machine [5- 6].
3. In addition, it is recommended to disassemble and clean it regularly depending on the usage. If you have strong hands-on ability, you can disassemble the washing machine by yourself, and clean up the dirt attached to the washing tank and the inner barrel wall; considering the safety of electricity use, it is best to invite professional home appliance cleaners to disassemble and wash it. After all, health is priceless~

Many air conditioners look bright and beautiful on the outside, but in fact they are already like this…
To use such an air conditioner, I can only say one thing: bacteria come too fast, like a tornado…
Research shows that air conditioners are an important source of indoor dust mites, and these dust mites are one of the important causes of allergic diseases [7].
Children are less resistant than adults. The use of air conditioners for more than 8 hours/day in summer is an important cause of asthma, bronchitis, pneumonia, and allergic rhinitis in children [8].
So, even for the flowers of the motherland, you must clean the air conditioner regularly! !
Air conditioner (indoor unit) cleaning method:
1. When cleaning the air conditioner by yourself, turn off the power first, and then clean the air conditioner casing with a clean damp cloth. If the air conditioner is in a high position, pay attention to safety when wiping.

2. Open the housing of the air conditioner, take out the filter (yes, the dirtiest layer in the picture above), brush lightly with a brush, and then slowly clean it.
(Source: Internet)
3. After the filter is dry, install it back and cover the air conditioner housing.
(Source: Internet)
The average person can do this step of cleaning the filter, which is very powerful! Such cleaning can be done every 3 months or so.
If you find it troublesome, you can ask a professional cleaning person to come and clean it thoroughly once a year or so.
Are you surprised after reading it?
These appliances are used every day
Remember to deep clean them regularly
If there is no (lazy) experience (should) test (wash)
You can also directly ask a professional to come clean
Friendly reminder, please pay attention to electricity safety
Favorite this article, open it when you can’t operate it~
