Has the answer to banishing Covid-19 been staring at us from the bathroom cabinet this whole time? According to a new study, it's certainly possible.

Scientists at Cardiff University found there were “promising signs” that over-the-counter mouthwashes may help kill the virus. Speaking on the report – which comes ahead of a clinical trial on Covid-19 – Dr Nick Claydon believes this could lead to mouthwash becoming an important part of people’s routines.

“If these positive results are reflected in Cardiff University’s clinical trial, CPC-based mouthwashes… could become an important addition to people’s routines, together with hand washing, physical distancing and wearing masks, both now and in the future.”

According to the report, mouthwashes containing at least 0.07% cetypyridinium (CPC) showed signs of being able to eradicate the virus when exposed to the virus in the lab. However, the research was keen to stress that although it may help kill the virus in saliva, there’s little evidence to show it can be used as a treatment for coronavirus, as the fluid is unable to reach the respiratory tract or the lungs.

The report, which is yet to be peer reviewed, supports another study that found CPC-based mouthwashes to be effective in reducing viral load.

Dr Richard Stanton, lead author on the study, said: “This study adds to the emerging literature that several commonly-available mouthwashes designed to fight gum disease can also inactivate the SARS-CoVo2 coronavirus [and other related coronaviruses] when tested in the laboratory under conditions that are designed to mimic the oral/nasal cavity in a test tube.”

While initial reports are promising, the full trial and results, which is looking at mouthwashes and its ability to reduce levels of covid-19 in the saliva, won’t be ready until early next year. The public should follow the government guidelines.

Hands, face, space, rinse and spit will have to wait for now.
