New Study Finds Mouthwash can Inactivated Human Coronaviruses
A new study conducted by researchers at the Penn State College of Medicine has found that a common dental item can inactivate human coronaviruses: mouthwash and oral rinses.
For the study, the results of which were published in the Journal of Medical Virology, researchers tested various oral and nasopharyngeal rinses — which included a 1% solution of baby shampoo, a neti pot, peroxide sore-mouth cleansers, and mouthwashes — to determine how well they inactivated human coronaviruses.
The baby shampoo solution, “which is often used by head and neck doctors to rinse the sinuses,” the researchers noted in a news release regarding the findings, was particularly effective; the solution inactivated “greater than 99.9% of human coronavirus after a two-minute contact time,” they said.
