The Truth About Stainless Steel

Stainless steel is used for many different appliances throughout many different industries. Whether it’s architecture and construction, medical, food, transport, hospitality, the touch surfaces you come into contact with are likely to be made from stainless steel.

The material is extremely popular, mainly because of its clean looking appearance; but just because it looks that way doesn’t mean it is.

Many believe that stainless steel is easy to clean. The surface is smooth and there is a huge number of products on the market we can use to disinfect.

Here at Hygi Group we worked with Professor Bill Keevil, Professor of Economic Healthcare at the University of Southampton. Professor Bill Keevil has spent years studying the antimicrobial properties of copper, and alongside that work has uncovered some truths about other materials such as stainless steel.

In an interview we conducted with Professor Keevil, he mentioned how stainless steel ‘hides a multitude of sins.’ What he meant by this was that when stainless steel is examined under the microscope, we can see lots of pits and crevices on its surface where pathogens can hide and survive very easily. What this means is that whilst we believe stainless steel is very easy to clean, we’re not actually able to reach all the bacteria and viruses on its surface as straightforwardly as once thought.

This is why at Hygi Group we want to reiterate the importance of using antimicrobial touch surfaces. A common argument for not using these kind of products is that people think they can just clean more often and that this will have the same effect. Whilst we don’t want people to stop cleaning, and actually advocate for people to use our antimicrobial metal alloy and continue regular cleaning, cleaning alone is not enough to kill the bacteria and viruses on these surfaces.

When we compare stainless steel to our Hygi Metal we can see how we can benefit from the change. Up until now people have been hesitant to make the change to copper alternatives because of its appearance. In Professor Keevil’s words, ‘'It's ironic that stainless steel became widely used because of its apparently clean looking surface.’ Many believe that copper looks dirty, when in fact, it’s one of the cleanest and safest materials you could use for touch surfaces. However, at Hygi Group we decided that no matter how many benefits our product had, people would still always be drawn to the appearance of stainless steel. This is why we created our Hygi metal alloy. It contains copper, and has all the antimicrobial benefits that copper offers, but looks just like stainless steel, so you can get the best of both.
