    It is totally unreliable. The "warm water washing method" circulating on the Internet believes that warm water washing can reduce nitrate. A related experiment showed that by soaking leafy vegetables in warm water for 10 minutes, the nitrate can be removed by more than 50%, and if only washed with cold water, it can only be reduced by 10%. However, Zhao Yongyi, director of the Clinical Nutrition Department of the First Affiliated Hospital of Guangdong Pharmaceutical University, told the media that washing vegetables with warm water is not reliable.
