An industry-defining standard of cleaning and disinfection

Chemicals Used

You may have heard the old term ‘Oils ain't Oils. ’ Well exactly the same applies to cleaning chemicals.

This part can get a little technical, but if you’re the sort of person that likes to know the Nitty Griity stuff, then please, read on.

The Vira Shield process is divided into a 3 step system for

good reason.

The Step1: Cleaning process is imperative in attaining the correct final outcome.

Choice of chemical is one of the main reasons for this.  The best Hospital grade disinfectant may kill every germ and Virus on the planet, but they perform extremely poorly at removing soiling such as oil and fats left from food, beverages or even fingerprints. These MUST be removed entirely during the First step utilising the correct type of chemical with components such as wetting agents and powerful emulsifiers to break down any soiling. This then allows the Disinfectant to do its job properly in the following Decontamination step.

If choice of chemical was important in the First step. It is even more critical in the second Decontamination step! You will have no doubt seen the ads on TV for Disinfectants claiming to “Kill 99% of germs and bacteria”  Sounds GREAT!  And whilst it may be perfectly true there are 2 problems with this type of claim. 

The first one is easy, Germs and Bacteria can be nasty little things, but they are NOT Viruses.

In fact, many ‘off the shelf’ products won’t even come close to killing virus pathogens.

The second problem is a bit more in depth.

Even if your average garden variety disinfectant is one that is capable of killing Viruses, the question must be asked… how many does it kill? 

This is where the Virus’ kill log’ comes in to play. Log stands for Logarithmic and works on a base 10 factor.  The chart below shows this better.

Basic maths tells you that if a disinfectant kills 99% of virus pathogens, then 1% are still left alive.  That 1% sure doesn’t sound like much,  until you realise that a virus such as Sars2, eg: Covid19  is, on average approximately 1 micron in size. That’s really  really small.  So much so, that 50 Million can fit onto a pinhead !  So if you only kill 99% of them, it stands to reason you still have 500,000 (that’s 1%)  left alive… ON YOUR PINHEAD !  Imagine how many might be left alive on a lift button or a door handle because of poor cleaning and decontamination practices.  Understanding this critical fact helps one to realise why viruses can be spread so quickly.


It is for this reason we ONLY use Disinfectants that have been tested and proven to kill 99.999%  (Log6) of the Sars2 Covid19 virus.  The industry standards in Australia is set by the ‘Therapeutic Goods Administration’ and they publicise a small  list of chemical proven to have passed the most rigorous testing program and can truthfully make the claim

“Kills Covid19 Virus”. 

All of the disinfectants we use in the Vira Shield system must be tested, passed and appear on that list! PERIOD. 

Using a garden variety disinfectant in your workplace is a bit like driving a car with only 3 wheels. You are headed for a train wreck!

Even though our disinfectants are super powerful Virus killers, they are 100% safe for your staff and your customers. When we have completed our decontamination process you will be able to confidently re-open your workplace in as little as an hour.
