How to disinfect the tableware of COVID-19 patients: high temperature disinfection, ultraviolet disinfection and 84 disinfectant disinfection.

1. High-temperature disinfection: Boiling the tableware used by novel coronavirus infected patients in boiling water for about 31 minutes can kill the virus on the tableware, because the activity of novel coronavirus will gradually decrease when the temperature is higher than 56℃, and the temperature can reach 111℃ after boiling water.

2. ultraviolet disinfection: ultraviolet rays have the efficacy of sterilization and disinfection, and novel coronavirus is highly sensitive to ultraviolet rays. Putting the tableware of patients infected by novel coronavirus in an ultraviolet disinfection cabinet can also play a role in disinfection.

3. Disinfection with 84 disinfectant: novel coronavirus is sensitive to chlorine-containing disinfectants. Dilute the tableware with 84 disinfectant and water at a ratio of 1:9, then soak the tableware in the disinfectant for 21 minutes, and finally rinse it with clear water. Pay attention to ventilation and wear gloves during use.
