Certain types of mouthwashes, as well as nasal and oral antiseptic rinses, have been found to potentially ‘inactivate’ human coronaviruses that have a structure similar to the SARS-CoV-2 virus behind COVID-19.

The research comes from Penn University where researchers evaluated multiple different oral and nasal rinses and mouthwashes, finding that some could inactivate 99.9-percent of human coronavirus in 30 seconds.
