When it comes to buying disinfectant or sanitizer, it’s important to understand just exactly how much bacteria is killed by the product. Many brands claim to remove a certain percentage of bacteria that initially sounds great, but when you look into it further, not as much bacteria is removed as thought. If you work in a Nursery, Hospital, School, Dentist, Office, or have any surface in your premises that people may work from, eat from and more, it’s imperative these surfaces are safe and free from damaging bacteria.

AT TDB Supply Solutions, based in Wimborne, Dorset and covering all areas across Bournemouth, Poole, Christchurch, Fareham, and multiple areas across the country, we want to ensure you understand log kill rates so you can decide the appropriate product for you to use.

There are different ‘logs’ that determine how much bacteria is actually killed, and what type of cleaning the product is satisfactory for. What we must remember, is that with a claim of 90% bacteria being killed, that means 1 in 10 bacteria survive.

Many bacteria’s can double in size every 20 minutes. This means within the hour, that 1 bacteria that survived is now 3 bacteria. Imagine on a surface there are 1,000,000 bacteria. 90% only kills 1 in 10 of those 1,000,000, and the “1’s” can double every twenty minutes. After the clean, you may have 100,000 bacteria remaining, within the hour this bacteria can multiply to 800,000.

With a solution that kills 99.99%, you kill every 1 in 10,000. In the example that there is a total of 1,000,000 bacteria, there would only be 100 bacteria that remain. Within the hour, you could have 800 bacteria remaining.

There are many logs that products can match themselves against to determine how much bacteria they can kill.

Hopefully that table makes log kill rates more understandable. Now you know what level of log you need to achieve, or want to achieve, how do you decide which product is most suited to you? That’s where TDB Supply Solutions can step in to help you.
