Cleaning operation of kitchen range hoods The range hoods and flues that have been used for a long time are not cleaned frequently, which will leave a lot of oil stains on the surfaces of the range hoods and flues. After a long time, oil stains will form, which cannot be removed by simple cleaning, affecting the use of range hoods and flues, making it difficult to eliminate smoke flow. The kitchen is an important area for safety and fire prevention, and it is particularly important to clean kitchen facilities and equipment, especially range hoods. Cleaning method of range hood: pressure cooker steam cleaning method. Boil the cold water in the pressure cooker. When the steam is continuously discharged, take the low-pressure valve, turn on the range hood, and aim the steam water column at the rotating blades. As high-temperature steam continuously rushes into the fan blades and other parts, oily sewage will flow into the waste oil cup along the way until there is no oil in the oil cup. Soaking method of detergent and vinegar. Remove the impeller, soak it in a pot of warm water mixed with 3-5 drops of detergent and 50 ml of vinegar for 10-20 minutes, and then scrub it with a clean rag. The shell and other parts are also cleaned with this solution.

This method has no damage to human skin and no corrosion to equipment, and the surface still maintains its original luster after cleaning. Soap liquid surface coating method. Make soap into paste, and then smear it on the surface of impeller and other devices. After a period of use, remove the impeller and other devices and wipe them with a rag, and the oil will fall off. When the range hood is covered with oil smoke, dust and sticky dirt, people often use sharp tools such as bamboo chips, steel balls and knives to clean up the thick grease, which will inevitably scratch the smooth surface of the range hood. Many people ask people to take it apart and wash it, thinking that it is labor-saving and thorough. As we all know, the range hood, a high-speed rotating machine, requires high dynamic balance. If the range hood is disassembled by a cleaner without mechanical knowledge, the dynamic balance will be seriously damaged.
