Do you think the clothes are really clean after each wash? The dirt left in the inner cylinder is not completely discharged with the sewage, and some are attached to the inner wall of the washing machine. Year after year, there are a large number of bacteria on the inner wall of the washing machine, which will increase with the increase of the number of times you wash clothes. Even if they are washed separately, the repeated washing process of underwear and outerwear also increases the number of bacteria. “Washing the washing machine is actually the process of infecting certain bacteria to the next barrel of clothes. Some bacteria may not be eliminated even by drying, especially the intimate underwear.” Han Guangen, deputy director of the Environmental Health Department of the Shanghai Center for Disease Control and prevention, also reminded the public at the meeting that they must be vigilant against “secondary pollution” of washing machines. However, the current full-automatic washing machines are more likely to cause mold breeding than the traditional double cylinder washing machines because of the difficult discharge of residual water and the small gap between the dewatering tank and the washing tank.
An investigation shows that there are not only pathogenic bacteria in the internal tank of washing machines, but also seriously exceed the national sanitary standards for cleaning and disinfection of public goods in the hotel industry. In the pollutants in the inner tank of the washing machine, not only general pathogenic bacteria such as molds and coliforms were detected, but also pathogenic bacteria such as Pseudomonas aeruginosa, spoilage bacteria, fermentation bacteria and Cryptococcus were found.
Professor GUI suiqi, doctoral supervisor of Fudan University’s affiliated obstetrics and Gynecology Hospital, said that up to 60.2% of the molds detected in the washing machine’s internal tank were very dangerous to women. At present, international statistics show that the proportion of women infected with mold once is 75%, while the proportion of women infected with mold twice after treatment is still as high as 40%. And mycotic vaginitis is very stubborn in treatment, especially for pregnant women, once infected with mold, the probability of abortion, premature birth and even stillbirth is very high. Mycotic vaginitis is also easy to cause women’s pelvic inflammation, cervicitis, cervical erosion and other gynecological diseases, which has a particularly serious impact on women’s health.
In fact, most of the bacteria in the washing machine are hidden in the interlayer between the inner liner and the outer cylinder, that is, the inner tank of the washing machine. At present, all automatic washing machines have internal slots. When the washing machine is working, the outer cylinder basically does not rotate, but the inner cylinder rotates. In the process of washing clothes, the dirty water from the washed clothes is discharged from the inner tank, and will stay in the inner tank for a period of time. However, the speed of drainage is not very fast, and it is easy to leave dirt in the inner tank over time. The interlayer of the washing machine is like a sewer, with scale, detergent free matter, clothing fiber and other organic matters attached. If not cleaned in time, these impurities attached to the interlayer will ferment and breed bacteria. Moreover, many families prefer to put washing machines in poorly ventilated and humid places such as toilets, which will promote the proliferation of bacteria in large numbers due to the high humidity of the environment. The investigation also found that the current full-automatic washing machine is more likely to cause mold breeding than the traditional double cylinder washing machine due to the reasons that the residual water is not easy to discharge and the gap between the dewatering tank and the washing tank is very small.
For ordinary citizens, developing scientific laundry habits is very useful in dealing with the secondary pollution of washing machines. First, the washing machine should be placed in a ventilated and bright place; Secondly, underwear and coat should be washed separately to reduce cross contamination of clothes. Finally, after washing the clothes, the cover of the washing machine should be opened for ventilation for a period of time, so as to keep the inside dry, so as to promote the volatilization of residual water and inhibit the growth of microorganisms. Moreover, the clothes should be taken out immediately to dry, not stuffy inside. If conditions permit, the washing machine can be cleaned regularly after three months or half a year. The special cleaning and sterilizing agent for washing machines disinfects and cleans your washing machines in a simple, easy and fast way.
Cleaning method: put the drain pipe of the washing machine on an empty bucket, close the water inlet valve and the front door. Pour 20 liters of water and 10 liters of detergent into an empty container and stir evenly. Pour the mixed detergent solution from the detergent addition box, and be careful not to splash it on the skin. Clean the machine body according to the daily washing mode. After the descaling solution is discharged from the drain pipe to the bucket, add the discharged descaling solution from the detergent addition box. Repeat this several times, and then open the filter to clean the filter screen. After cleaning with descaling solution, clean the filter screen again with clean water according to the daily washing mode.
After each washing, drain the sewage and clean the washing machine barrel with clean water; Dry the water drops and accumulated water inside and outside the washing machine with a dry cloth; Restore all knobs and keys on the operation panel to their original positions; The drain switch is indicated in the closed position, and then placed in a dry and ventilated place. When brushing the washing machine, do not use strong alkali, gasoline, alkene and hard brush. When cleaning the filter screen and drain pipe, do not use hard tools.
