Killing Bacteria with Jangro Sanitisers & Disinfectants

You know when you see an advert for a disinfectant and it says 'Our product kills 99.9% of bacteria leaving your kitchen sparkling', or something along those lines? Well, how effective is 99.9% in reality and when we say that our products kill 99.999% of bacteria is that just a childish way to get above the competitors or an accurate assessment that makes a huge difference?

Breaking Down the Numbers - and the Bacteria

Without knowing the inside info there's no reason why you wouldn't think that a 99.9% effectiveness wasn't great. I mean, it's not awful but there is a huge difference when compared with our own products being 99.999% effective, and here's why.

Bacteria will always multiply, there's no argument there. So if a product is being used on an area with 1,000,000 bacteria as an example how much would 99.9% leave behind?

It would leave behind 1000 bacteria on the recently disinfected area. This doesn't sound so bad really, but when you consider that bacteria multiplies, at different rates dependent on the conditions, you could be left with 256,000 bacteria just 2 hours after disinfecting the area.

Now, what would happen in the same circumstances but using the 99.999% effective disinfectant?

Only 100 bacteria would be left behind out of the 1,000,000 we began with. That's a pretty impressive drop in numbers we're sure you'd agree. Even better, with the same multiplying factors after 2 hours there would only be 256 bacteria present. You're already seeing huge gains.

What's the Big Deal? 99.9% Is Still Pretty Amazing?!


Bacteria being present on a surface will not automatically lead to infection for anyone who comes into contact with it. But, a person who is more vulnerable to infection can get ill from as little as 100 bacteria cells. When you put that together with the information above about the difference in effectiveness of 99.9% and 99.999% and you'll start to see why products should have the higher rating.

The European Standard Test Methods specify that in order for a disinfectant to pass its test there must be a 99.999% effectiveness for killing bacteria, so why aren't we swamped with this number on television advertising instead of the standard 99.9% we're so used to hearing about?

Take a look at some the Jangro commercial cleaning chemicals and check the credentials of these sample products by asking for a copy of the microbiological lab reports, with tests against bacteria such as Salmonella, MRSA and E-coli for diseases such food poisoning, dysentry to determine just how good and effective these products are, including:
Realistically you're never going to have a fully 100% effective disinfectant that kills all bacteria in its wake. Instead you should focus your efforts on purchasing products that come as close to that as you can. Next time you see a sign promising 99.9% of all bacteria killed by the product in front of you, remember that there are cleaner disinfectant products out there with more effective numbers and Wray Bros can help you.
