wash the air conditioner before and after use
As the temperature keeps rising, every household’s air conditioner has begun to be put into use again. Experts remind that for air conditioners that have been shelved for a long time, cleaning before use is very important.
Household air conditioners are simple in structure and easy to clean. When the weather turns cool every autumn and the air conditioner is no longer in use, the dust filter should be taken down according to the instructions, washed with clean water for several times, and then dried. It’s best to clean it like this before reuse in the next summer. If you can’t wash it with water, you can gently brush it with a soft brush.
For air conditioners that have been in use for 3 years, professional personnel need to carry out a professional and systematic cleaning and maintenance. Generally, the central air conditioner should be fully and systematically cleaned by professionals every 3-4 years, which can not only maintain the ventilation quality, avoid infectious diseases of respiratory tract and skin, but also avoid failure.
the refrigerator should be cleaned once a month in summer.
In summer, the temperature is high, and the food is easy to breed bacteria. Timely and effective cleaning of the refrigerator can make food stay longer and reduce the peculiar smell in the refrigerator, which is more beneficial to health.
It is recommended to empty the refrigerator every 2 weeks or at least once a month, discard expired, broken and unsuitable food, and thoroughly clean the refrigerator. Wipe the inside and outside of the refrigerator with warm water or neutral detergent. If there is a peculiar smell in the refrigerator, first clean it with bleach diluted with a concentration of about 1%, and then wipe it with clean water. You can also deodorize coffee grounds and tea grounds, dry the soaked tea leaves, put them in a small container and put them in the refrigerator to absorb the odor. Other natural deodorants, such as baking soda powder and lemon juice, can be renewed once every 1-3 months. As soon as it is found that there is food dripping out of the soup, immediately take a rag to wipe it clean.
wash the washing machine every two to three months
In summer, people sweat a lot, wash clothes more frequently, and there are more intimate clothes. Always clean the washing machine.
Generally, a newly bought washing machine should be cleaned and disinfected every two or three months after it has been used for half a year. When cleaning, it’s better to use a special cleaner, or “baking soda and white vinegar”.
First fill the washing machine with water, add a small cup of baking soda powder, let the washing machine rotate for 3-5 minutes, soak for at least 30-60 minutes, drain the water, fill it with water, and turn it for five or six minutes. The second step is disinfection and sterilization. Add a small bottle of white vinegar (about 300 ml) to the clean water, let the washing machine rotate for a few minutes, soak it for more than 30 minutes, and then wash it again with clean water.
carefully clean the screen window to keep it cool all summer.
In the sultry summer, opening windows for ventilation is essential, and screen windows are the only barrier between the room and the outside world. But the screen window has been used for a long time, especially after the accumulation in winter and spring, it should be cleaned in advance. Otherwise, it will not only pollute the indoor air, but also shorten the life of the screen window.
Since only some dust is attached to the screen windows in the bedroom and living room, you can remove the screen windows and wash them with clean water. You can also spread newspapers on one side, brush the dust with a soft brush, and then turn over to clean the other side; When cleaning the kitchen screen, you can use some detergent or washing powder and brush it clean.
If the stains are stubborn, take an appropriate amount of washing powder, a small amount of milk and water, mix them together to make a cleaning solution, dip them with a soft brush and smear them on the screen, and then rinse them with clean water after 5-8 minutes. The screen will be the same as the new one. Flour can also be used. Because of the large surface tension of flour particles, it can absorb various oil stains. After wetting with water, the coarse fiber and starch in the powder will expand when they meet water, which has a strong removal force for oil stains.
There are also many people who use invisible screen windows, which can be put into the net box when not in use. This kind of screen should also be cleaned regularly. At the same time, pay attention to the lubrication of the track and add some oil to the positioner. Once the yarn surface is damaged, it should be replaced in time.
