Could baby shampoo and mouthwash be a key to slowing the spread of COVID-19? Maybe. According to a new study, nasal and oral rinses like mouthwash can deactivate human coronaviruses. Researchers tested a number of products including a neti pot, peroxide sore-mouth cleansers, mouthwash and one-percent baby shampoo, to see how each would lower the viral load of coronavirus strains in a patient’s mouth. Their findings reveal most of these products effectively shut down virus particles in less than two minutes.
