How Effective Are Disinfectants In Killing Bacteria And Germs?


We’re no stranger to using a whole bunch of disinfectants to keep our home safe and germ-free, but are you sure that the products you’re using are REALLY effective against bacteria and germs?


We often think that any regular disinfectant will get the job done, but it’s also important to know that not all disinfectant products in the market are equally effective on all kinds of germs. Most germs are harmless, but some can be pathogenic — which means they have the potential to harbour disease-causing bacteria and viruses that may lead to serious health effects. The process of disinfection allows you to eliminate disease-causing pathogens on surfaces and in the air, therefore reducing the chances of infection. However, not every product has the ability to kill them all.


So, how do you ensure that a disinfectant works as it claims? And how do you use one for maximum effectiveness? Here are some factors that will help you to determine the effectiveness of a disinfectant product.


Kill rate


Is there a difference between 99.9% and 99.999%? Yes, there is!


The efficacy of a disinfectant product is measured by its kill rate, which is used to indicate the percentage of bacteria and germs that are killed. The higher the kill rate, the greater the reduction in the amount of pathogens — for every extra ‘9’ added to the kill rate, the number of germs present is reduced by 90%.


For instance, if you disinfect a high-touch surface that contains 1 million microbes with a product that kills 99.9% of bacteria, 1,000 microbes would still be left behind. Comparatively, using a disinfectant with a 99.999% kill rate would result in only 10 remaining ones. This shows that a 99.999% kill rate is 100 times more effective than a 99.9% kill rate!

Contact time


All disinfectants need to stay wet on the surface for a specific amount of time in order to thoroughly eliminate all bacteria and germs. This is known as the contact time, which can range from 15 seconds to 10 minutes depending on the instructions indicated by the manufacturer. It’s usually shown on the back of the product label.


So, in practice — if you were to spray a surface with a disinfectant, the contact time stated refers to how long the solution needs to remain on the surface in order to achieve the optimal results. If the solution dries or gets wiped off before the desired contact time is met, then there’s a high possibility that germs could still be present.


Your best bet is to choose a fast-acting disinfectant with a speedy contact time so you won’t have to wait around for it to take effect, minimising the hassle of reapplication.


Type of germs


It’s commonly believed that disinfectants can kill all types of germs on surfaces, but the truth is that it may not be effective on a certain strain of pathogen. Some are found to be more effective against viruses such as influenzas and common colds, but they may not be as effective against fungus and spores which can also present significant health risks.


It’s important to know exactly what your targeted germs of concern are. Before deciding on which disinfectant is right for your specific needs, be sure to check the label to verify the claims. What are the different types of bacteria and germs that the product is said to combat? Has it been tested and proven to be effective against these pathogens? Understanding the level of efficacy of a product will help to protect yourself and others around you from exposure to harmful germs.
