1. 高压锅蒸汽冲洗法。把高压锅内冷水烧沸，待有蒸汽不断排出时取下限压阀，打开抽油烟机，将蒸汽水柱对准旋转扇叶，由于高热水蒸汽不断冲入扇叶等部件，油污水就会循道流入废油杯里，直到油杯里没有油为止。
1. High pressure boiler steam washing method. Boil the cold water in the high-pressure boiler, take the lower limit pressure valve when there is steam continuously discharged, open the range hood, align the steam water column with the rotating fan blade, because the high hot water steam continuously rushes into the fan blade and other parts, the oil sewage will flow into the waste oil cup along the way until there is no oil in the oil cup.

The shell and other parts are also cleaned with this solution. This method has no damage to human skin, no corrosion to devices, and the surface remains original luster after cleaning.
3. 肥皂液表面涂抹法。将肥皂制成糊状，然后涂抹在叶轮等器件表面，抽油烟机用过一段时间后，拆下叶轮等器件，用抹布一擦，油污就掉了。
3. Soap liquid surface coating method. Make the soap into a paste, and then smear it on the surface of the impeller and other devices. After using the range hood for a period of time, remove the impeller and other devices, and wipe it with a rag, and the oil stain will fall off.
