Hydrogen peroxide is also a commonly used chemical disinfectant in hospitals, and the new treatment guidelines for novel coronaviruses now clearly state that hydrogen peroxide can kill novel coronaviruses. The condition for hydrogen peroxide to kill novel coronavirus is to ensure effective concentration. If the hydrogen peroxide is not well preserved and the concentration is too low, it will not be effective in killing the virus. In addition, hydrogen peroxide kills the virus for a sustained period of time. Ensure the concentration and ensure the effective time of action, in order to be able to play such a role in killing the virus. Source: Dr. Yurai
