Mouthwash can kill coronavirus within 30 seconds of being exposed to it in a laboratory, a scientific study has found. The preliminary result comes ahead of a clinical trial into whether using over-the-counter mouthwash has the potential to reduce the levels of Covid-19 in a patient's saliva.
The Cardiff University report said mouthwashes containing at least 0.07 per cent cetypyridinium chloride (CPC) showed "promising signs" of being able to combat the virus.
The report is yet to be reviewed but supports another study published last week that found CPC-based mouthwashes are effective in reducing Covid-19's viral load.
