A microbiologist with more than 40 years of experience says the term “deep clean” thrown around by businesses is a “public pacifier” and firms are not doing enough to mitigate Covid-19 transmission risks following positive case exposure.

Ben Harris, the medical microbiology scientist, and lecturer at the University of Otago, says the now-famous phrase “deep clean” is in fact not deep, and research shows that the virus can continue to live on surfaces even after a clean has taken place.

Manual cleaning, even with disinfectants, is an ineffective method to mitigate transmission risks, he says.“The biggest risk is shared air, and then touch surfaces,” says Harris.

So what do businesses actually need to do to get rid of any traces of Covid?

Harris’ first piece of advice is “not to do a manual clean”, and instead use fog canon disinfectants as a way to effectively sterilize both the air and surfaces.“If there is a known case [that has visited the premise] everything should be fogged with high-level disinfectant fog, not residual ones.”

Cleaning Commercial Companies have the money and resources to get their clients to change from doing a manual clean to fogging/misting.
A CCC may have 200 clients but only 10 of those clients may be willing to switch to a more modern way of cleaning/disinfecting their premises.
CCC will be pushing for their clients to make the change, which means this will eliminate/reduce the need for any other cleaning products.

During lockdowns, buildings are still cleaned as per their contract.
