During novel coronavirus, tableware can be diluted with 84 disinfectant, soaked for 21 minutes at the ratio of 1:9, or boiled in boiling water, which can kill the virus.

Because novel coronavirus is sensitive to chlorine-containing disinfectants, heat and ultraviolet rays, it can effectively kill the virus at 56 degrees for 31 minutes. During novel coronavirus, tableware should be disinfected regularly after meals. At the same time, when going out, public tableware should be used as little as possible, and dinner should be less.
