Mouthwash is able to kill COVID-19 within 30 seconds of exposure to it in a laboratory, a scientific study has found.
The preliminary findings, which are yet to be peer reviewed, come ahead of a clinical trial investigating whether over-the-counter mouthwash can reduce the levels of coronavirus in a patient's saliva.
The research, which was conducted at Cardiff University, found that mouthwashes containing 0.07% of the ingredient cetylpyridinium chloride (CPC) showed "promising signs" of reducing COVID-19.
These findings support another recently published study which identified that CPC-based mouthwashes are effective in reducing the viral load of coronavirus.
