Wits scientist says firms are ‘exploiting ignorance and fear’ with deep cleans

Scientists say “deep cleans” of offices, schools and other spaces every time a positive case is reported, is unnecessary. A Bizcommunity report says many companies are exploiting ignorance and fear and selling COVID-19 cleaning solutions that are unnecessary and expensive.

However, regular cleaning with household products is sufficient, says Professor Francois Venter, an infectious disease doctor at Ezintsha, Wits University. “These so-called ‘deep cleans’ after a work colleague tests positive are absolutely unnecessary. Regular, normal cleaning of surfaces using standard household products, like water and bleach, are sufficient. If you spend thousands of rands on a ‘deep clean’ and someone with COVID-19 sneezes or coughs and touches things in the room a short while later, what was the point of it? Do not get distracted by endless angsting about catching it off a surface; it infects the vast majority of us through the air. So distance, masks, outdoors will keep you safe, not strong chemicals,” he says.

“The Department of Health and the Minister of Health have warned against the use of sanitising tunnels,’ says Momeena Omarjee of the law and enforcement division of the SA Health Products Regulatory Authority.

And a recent article in the South African Medical Journal states: “To mitigate the spread of the SARS-CoV-2 virus, a concerning practice of spraying individuals with disinfectant via so-called ‘disinfection tunnels’ has come to light. The Allergy Society of SA supports the World Health Organisation in strongly condemning all human spraying, owing to lack of efficacy and potential dangers, especially to patients with coexisting allergic conditions.’
