1, pressure cooker steam washing method. Boil the cold water in the pressure cooker. When steam is continuously discharged, take the lower pressure valve, open the range hood, and aim the steam water column at the rotating fan blades. Because the high-heat steam continuously rushes into the fan blades and other parts, the oily sewage will flow into the waste oil cup along the way until there is no oil in the oil cup.

2, detergent, vinegar soaking method. Remove the impeller, soak it in a pot of warm water mixed with 3-5 drops of detergent and 51 ml of vinegar, soak it for 11-21 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 devices, and the surface still maintains its original luster after cleaning.

3. Soap liquid surface coating method. Make the soap into paste, and then smear it on the surface of the impeller and other devices. After a period of use, remove the impeller and other devices and wipe them with a rag, and the oil stain will fall off.
