Cabbage is formed into a ball. Don't think that it is clean when you break it open and see that there is no mud in it. In fact, it is only the surface.

The correct way is to cut it first, rinse it under the tap for three minutes, soak it in clear water for half an hour, change the water at least three times during the period, and finally rinse it for two minutes.

For cabbage, our most important thing is to clean the pesticides left on the leaves.

In the process of planting, it will inevitably be sprayed with various pesticides. Unlike other leafy vegetables, it will be wet by dew at night and dilute some pesticides.

The leaves of cabbage are covered layer by layer, and the pesticides sprayed on the leaves are all wrapped. Don't say that they can't be diluted by dew, even when vegetable farmers water it, they can't remove much pesticide residue.

So, you say, how many pesticides will be contained in a big round cabbage?

These things can still be seen with the naked eye. If they are washed clean, they will be gone, and the pesticide residues will be different. You have to wash the vegetables with water patiently over and over again.
