The content of acetic acid in edible vinegar is relatively low, generally about 5%~8%, which can’t achieve the effect of killing the new coronavirus. At the same time, acetic acid emanates into the air, its concentration will be reduced to enhance the air acidity environment is limited, can not achieve the purpose of killing the virus, so indoor use of vinegar can not kill the new coronavirus.
