First, prepare a container, pour baking soda and white vinegar, then squeeze in a drop of detergent, pour in water and stir well. Then soak the cotton towel in the solution for 5 minutes and then pick it up and squeeze it out. You can let the cotton towel stand on the range hood for 10 minute, so that the solution can fully decompose the oil stain on it, and finally clean it with a clean cotton towel.

1. The range hood, also called the range hood, is a kitchen appliance for purifying the kitchen environment. Installed above the kitchen stove, it can quickly pump away the burning waste of the stove and the oil fume harmful to human body generated in the cooking process, at the same time condense and collect the oil fume, reduce pollution, purify the air, and have the functions of anti-virus and explosion-proof safety guarantee.

Second, the smoke exhaust in early family kitchens was done by exhaust fans. Although the exhaust fan can remove most of the oil fume in the kitchen, it can't solve the pollution of the oil fume produced in cooking to the whole kitchen. Cooking fume contains many substances harmful to human body. If people work in a room full of oil fumes for a long time, it will lead to many diseases.

Third, the WHO research report shows that among the 4.3 million people who died of kitchen air pollution in 20 12 years, 34% suffered from stroke, 22% from chronic obstructive pulmonary disease, 26% from ischemic heart disease and about 6% from lung cancer.

4. In a research project on disease risk assessment published by the famous British medical journal The Lancet, kitchen air pollution (smoke) has been listed as the biggest health hazard after hypertension, smoking and alcoholism. Every year, the number of people who die from continuous inhalation of smoke from kitchen fires is more than the total number of deaths caused by malaria, tuberculosis and AIDS.

5. The study of farmers in China by the Journal of National Cancer Society in the United States also confirmed the impact of kitchen air pollution on people's health. Scientists from China and the United States who participated in this study surveyed more than 20,000 farmers in Yunnan Province and found that the probability of lung cancer was about twice that of those who had no ventilation in their stoves.

Six, China people's diet structure is different from that of westerners, so the variety, style and layout of kitchen utensils are very different from those of western countries. China is a country that pays attention to diet. In food processing, frying, frying, boiling and frying account for a large proportion. Therefore, there is a lot of oil smoke in Chinese kitchens, which makes the kitchen environment greasy and difficult to clean. So the range hood has become a necessary machine to change the kitchen environment.
