The Biggest Germ Gathering Spots In Your Office

Posted November 4, 2022


Surfaces and items that get touched often in an office space will risk having bacteria and germs on them. From desktops to keyboards, coffee pots to door handles, numerous areas around an office space could have germs growing on them. When someone touches these surfaces, the germs attach to their hand and get carried to their next stop. Human contact is the highest risk factor for germ transmission in an office or workspace. The more people that use an elevator button, the higher the number of germs growing on it.

We like to think that we keep our hands clean when moving from place to place. Even using hand sanitizer between touching high-contact surface areas isn’t always enough to kill all germs. It’s easy for companies to keep their office spaces clean and germ-free by hiring professional cleaning and sanitizing services regularly. These cleaning companies, such as Corvus Janitorial Systems, have experience in keeping high-contact surfaces germ-free.

Why Hire a Janitorial Service?

Companies that offer office cleaning services are excellent assets for high customer volume business locations. Restaurants, office buildings, stores, schools, hospitals, and clinics are all high-volume locations that see numerous customers daily. Add to that the number of employees at the business location, and the number rises significantly. The more people that visit a business location and touch surfaces, the higher the risk of germs and bacteria. A professional cleaning and janitorial service can reduce this risk significantly.

Common Locations for Germs

Germs live on almost every surface around an office. There are, however, certain areas where constant human contact creates a breeding ground for germs to survive for long periods. Surface areas such as elevator buttons, light switches, doorknobs, door locks, toilet handles, faucets, vending machines, and other high-contact surfaces will retain germs longer the more they get touched. Keeping these surfaces cleaned and sanitized is the only defense an office space has against germs.

The following is a detailed list of surface areas that germs will find easier to breed in due to high contact:

Elevator Buttons

Elevator controls see a lot of attention throughout the day. Both the controls in hallways and the control inside the cab of an elevator see constant contact from visitors riding the elevators through an office building. It’s always a good idea to clean doors and rails inside the elevator cab due to contact from riders.

Door handles, knobs, and locks

Doors will see the most use in an office space throughout the day. Everyone in the office will use a door multiple times during their work shift, making them a high-contact surface area to sanitize when fighting germs in an office space. Always clean the door’s surface around the handles also, due to people pressing on the door to help open it at times. Locks and latches will also need sanitizing when cleaning doors.


Workspaces often carry the most germs due to being high-contact surfaces. These workspaces can include cubicles, countertops, tabletops, desktops, and other flat surfaces where someone spends time constantly. Germs travel by contact with people’s hands, spreading about as far as a person can reach from any given point.

Keyboard, Mouse, and Trackball

Electronics that get constant use, such as input devices for computers like keyboards and mice, will see the most germs in a workspace. People constantly eat at their computers while working, leaving crumbs, oil, grime, and other tidbits that contribute to germs. If co-workers share a workspace, the amount of germs rises significantly.

Telephones, Fax Machines, Printers, and Other Shared Devices/Appliances

There are many appliances and devices in an office space that co-workers share amongst themselves. Coffee makers, printers, fax machines, copiers, shredders, vending machines, kitchenettes, microwaves, refrigerators, and many other devices or appliances get constant use in an office space. Co-workers using the same copier repeatedly will have shared their germs and others that have used the machine. Watercoolers are also a high-contact area for germs to breed.

Sinks, Dishes, Sponges, and Soaps

Having a nice breakroom is excellent until the kitchenette doesn’t get cleaned properly. Sinks and dishes are the most common breeding grounds for coli and salmonella. Most new sponges will have these bacteria on their surfaces within three weeks. Using these germ-ridden sponges throughout the day will spread the germs to other surface areas. Two minutes in a microwave can kill most germs on dishes, but we recommend replacing the sponge every two weeks to prevent these bacteria.


Coli bacteria thrive in bathrooms. Every surface in a bathroom is likely to have some stage of E. coli bacteria growing on it. Faucets, sinks, countertops, trashcans, handles, rails, and everything in between is at risk of bacteria in a restroom. Keeping these areas cleaned regularly can help reduce the risk the bacteria poses.


The most overlooked hotspot in any building for germ distribution is the air around us. You cannot sanitize the air itself. The recent Covid pandemic has taught us that contaminants can linger in the area for a while. Good ventilation helps keep the air cleaner to breathe. Adding fresh air into the mix will help, especially with a fan running. Replacing air filters in HVAC systems and keeping them well maintained also helps.

Depending on the type of business, hiring professional cleaning services like Corvus can often be the best solution for a workspace to remain a germ and bacteria-free environment. Some companies will have other high-contact areas that pose a risk of bacteria or germs growing on them. Restaurants, for instance, will have surface areas like tables, chairs, booths, menus, and other items or surfaces that customers come into contact with daily.

Staying Germ-Free

Keeping an office space germ-free is easy with the help of a professional cleaning service and some patience. Regularly cleaning a workspace and its high-contact surface areas will reduce the number of germs and bacteria that put visitors and employees at risk. Hiring a professional cleaning service is quick and easy. All it takes is making a quick call or scheduling an appointment to get an estimate. Keep your office space, employees, and visitors safe from bacteria like E. coli and salmonella with professional janitorial help.
