1, cabbage can be washed directly with flowing water, and every leaf must be washed in place when washing. Of course, you can also choose soaking cleaning, soaking cabbage in clear water, and then washing it with water.

2. Before cleaning the cabbage, you need to remove the outside leaves, because the outside leaves are easy to have pesticide residues. It is best to pick out the outer leafy vegetables before cleaning. The stem is also the most prone to residual pesticides, and the stem must be partially removed before cleaning.

3. If you feel that the cabbage can't be washed with clean water, you can choose to wash the leaves with rice washing water, which can effectively remove the toxicity. Because the rice washing water is alkaline, it can also remove the residual pesticides.
