1, cold water wash. Soak the picked vegetables in clear water for a period of time, wash off the dirt such as sediment on the vegetables, and then rinse them repeatedly.

2, salt water wash. There are many eggs on vegetables in summer and autumn, so it is difficult to wash them off with cold water. You can soak the picked vegetables in 2% salt water for 5 minutes, and the vegetable worms will fall off because of the contraction of the suction cups on your feet, and then rinse them repeatedly with cold water.

3. Wash with detergent solution. Drop 5-6 drops /2500g of detergent into a water container, soak the raw materials for 3-5 minutes, and then wash them with clear water. This method is mainly used for one or several vegetables whose surfaces are polluted by pesticides. Contaminated vegetables can't be washed simply or cleanly.
