What is the topic of the composition about the cleaner? The hard work of a good cleaner and the clothes of the city.
In the blue sky, the sun seems to be angry, making people put a stove on their heads. In this annoying weather, most people like to stay in a comfortable home, but the students in Puxie Primary School are different. They all bring glory.

And participated in the "Three Million Teachers and Students Entering the Community" activity.
With the autumn wind, humming a ditty, I walked into our "site". I looked at the ground and thought: no garbage! It seems that the cleaner is not so hard. With the teacher's command, the four of us started to act. The original clean ground, like a dirty dress, turned out to be garbage hidden on the ground in the corner. No wonder it looks so spotless.
Looking at the dirty ground, I suddenly felt a kind of power and thought: I must sweep the ground clean! We destroyed a lot of rubbish with high morale. Watch.

The room is full of people, and our hearts are full of pride.
Sweat on my face flowed down disobediently. I wiped my sweat and regretted my first thought: the cleaners are so hard that they have to rise from the sun to bask outside every day, whether it is cold or hot, but I think their work is very simple. I must help them lighten some burdens, though it is so insignificant.
I looked at the ground, my mouth was raised, and I smiled knowingly. The earth finally took off its dirty clothes and put on new clothes. The autumn wind blows my cheek again, and the familiar tunes echo in my ears.
How to disinfect cars in an epidemic situation? Some pictures are really like movie scenes.
Empty streets, faces under white masks, closed cities, unspeakable loneliness. This is the true portrayal of the epidemic, which not only broke our original plans and expectations, but also intertwined reality and illusion.
In order to cope with the epidemic, strict prevention and control measures have been taken all over the country, among which the safety of public transportation is particularly important. Taking Beijing as an example, the transportation department not only controls the density of people in subways and bus compartments, but also adopts a variety of strict disinfection measures.
For example, taxis and online car rides also require their drivers to always wear masks and guide passengers to sit in the back row, thus effectively inhibiting the spread and infection of the virus.
For many private car owners, how to make their families and passengers comfortable and safe under the epidemic situation is also a top priority. Today, I will talk with you about how to ensure the cleanliness and safety of our private car under the problems of whether to wear a mask when driving and how to disinfect the car.
Pay attention to the ventilation in the car
Under normal circumstances, private cars are more careful and intimate when used, cleaner and more hygienic than buses. If you are in an open parking environment, you can do a good job of ventilation, but you should pay attention to the fact that the weather in February is still relatively cold to avoid symptoms such as colds due to the large temperature difference between inside and outside the car.
If our private car is in a closed environment such as an underground parking lot, we suggest you close the window and open the circulating ventilation inside the car.
Pay attention to the disinfection of people and cars.
When drivers or passengers of private cars return to their cars from some public places, it is suggested that you wipe your hands with disinfectant wipes. If possible, you can use disinfectant to clean exposed body parts such as hands and face to avoid bringing harmful substances such as viruses into the car.
At the same time, it is necessary to clean and disinfect the car in time. Under normal circumstances, we can use a little disinfectant to mix disinfectant according to the ratio of 1:20, which is probably the ratio of a bottle of bottle cap disinfectant+a bottle of mineral water.
We can wet the rag with mixed disinfectant and use it to wipe the steering wheel, door handle, window and other automobile facilities.
As for the fabric parts such as car seat covers, we can use clothes sterilization agent to clean them. First, pour the drip sterilization agent of two bottle caps and a proper amount of laundry detergent into clean water, then put the seat cover in it and soak it for about 15 minutes, and then clean it according to our normal laundry process.
Besides dropping disinfectant, we can also use 84 disinfectant, peracetic acid and Lysol for cleaning and disinfection. Next, let's talk about how to use them.
When we use 84 disinfectant, we should pay attention to diluting it with 200 times of water. The use method of peracetic acid is to dilute its stock solution with water to a concentration of 0.2%-0.5%. It should be noted that peracetic acid is easy to volatilize. In order to ensure the use effect, we'd better mix it.
Lysol water, like the above two disinfectants, should be mixed with water, and its solution concentration is about 1%-3%. We can put Lysol solution in a small watering can and spray it on the surface of objects in the car for 30 to 40 minutes for disinfection.
It should be noted that the above three disinfectants are corrosive to some extent, so they should be used correctly according to the requirements of the instructions when mixed.
After we wipe it with disinfectant, it is also important to open the window for ventilation. Before driving and entering the car, open the door for ventilation for at least half an hour.
In addition to self-disinfection, you can also find some professional disinfection personnel to clean up (try to do it yourself in an epidemic situation). Although professional disinfection is expensive, it can ensure better disinfection and cleaning effect, and there are many kinds of disinfection.
Ozone disinfection
The so-called ozone disinfection is accomplished by using a vehicle-mounted sterilizer that can generate a large amount of ozone quickly. After sterilization, oxygen can be quickly decomposed without causing secondary pollution in the car.
It should be noted that if the ozone concentration in the car is too high, it will not only cause gas pollution in the car, but also have a certain impact on human health while sterilizing.
Photocatalyst disinfection
The principle of photocatalyst disinfection is completed by the reaction between photocatalyst coating and sunlight, which can quickly decompose harmful substances in our car into harmless and stable substances.
However, photocatalyst disinfection can only work under ultraviolet radiation, which will cause certain damage to our human health, so photocatalyst disinfection needs professional operation.
Ion disinfection
Ion disinfection, as its name implies, is to release ions in the car by using the car oxygen bar, but this disinfection method has great limitations. Because the overall volume of the car-mounted oxygen bar is relatively small, and the ions released by it are also very limited, the process of purifying the overall air in our car is very slow, and the sterilization treatment is not thorough enough, which is not worth recommending.
Steam sterilization
Before steam disinfection, the car should be cleaned first, then the detergent in the car should be sandblasted, and then disinfected with high-temperature steam.
The disadvantages of this disinfection method are long disinfection time and low efficiency, and long-term use of steam will cause short circuit and other adverse effects on electronic equipment in our car.
Finally, we'd better wear masks when traveling by car. At the same time, the best protection measure is to reduce traffic jams in China. Come on, China!
