Bacteria and harmful microbes are all around us. They can cause infections and health issues if not dealt with properly. One square inch of human skin can contain up to 600,000 bacteria.

Microbes that are harmful and cause diseases- known as pathogens- can be even lethal. In the current times of COVID-19, it has become even more important to keep our home and offices clean. You can use a suitable disinfectant to clean the surfaces that are most frequently touched.

These surfaces can include kitchen countertops, doorknobs, desks, mobile phones, etc. Doing so can keep them free of any harmful bacteria and other pathogens and keep you and your family safe.

How Do Disinfectants Kill Bacteria?

Disinfectants contain chemicals that are effective in killing bacteria and other microbes. Most common disinfectants in the market contain water, detergents, and fragrances.

They also contain an active formula that kills bacteria and pathogens. Disinfectants impact the cell structure of microbes and kill them. Active ingredients in disinfectants are aided by other ingredients too. Surfactants are added to disinfectants to ensure a more consistent and better wetting of the surface and improve the cleaning process.

What to Consider When Choosing Disinfectants

There are many things that you should carefully consider before buying a disinfectant.

The first factor to consider is whether the disinfectant can kill the microbes and pathogens you want them to kill. If you want to be safe from coronavirus, then ensure that a disinfectant can kill it before making the purchase.
