Steam cleaning method of pressure cooker. 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.

2.

Soaking method of detergent and vinegar. Remove the oil smoke extraction impeller, soak it in warm pot 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.

3.

Soap liquid surface coating method. Make soap into paste, and then smear it on the surface of impeller and other devices. After the range hood is used for a period of time, remove the impeller and other devices and wipe it with a rag, and the oil will fall off.
