Computer keyboards are often real germ hotspots and rank among the most contaminated items in the office. The risk of germ transmission increases significantly at shared workstations, making regular cleaning, disinfection of workstations and a clean desk policy essential.

Clean keyboards and healthy teams in the workplace
One aspect of hygiene in the office is often underestimated: computer keyboards are genuine germ hotspots. Studies show that up to 97% of keyboards carry microbes, including potentially harmful pathogens such as Staphylococcus aureus or multi-resistant bacteria. In open-plan offices and shared-desk environments, the risk of transmission increases substantially.
For employers, facility managers and employees alike, regular cleaning and disinfection of workstations and keyboards is essential for maintaining hygiene in the office. This helps reduce sick days and supports productivity.
Why computer keyboards are true germ carriers
When it comes to microbial load, computer keyboards hold a dubious record: studies confirm that an average keyboard can carry up to 400 times more bacteria than a toilet seat. Researchers at the University of Arizona found that keyboards in open-plan offices or shared-desk setups are particularly contaminated.
The list of possible pathogens reads like a mini ‘Who's Who’ of office germs: not only the usual suspects such as Staphylococcus aureus, E. coli and streptococci, which are responsible for a wide range of infections from the skin to the respiratory tract and urinary tract, were detected on keyboards. Multiresistant germs such as MRSA (a strain of Staphylococcus aureus that is particularly problematic in hospitals and care facilities and can lead to blood poisoning, among other things) have also been detected. According to studies, they are present on every seventh keyboard. They also harbour bacteria such as Enterococcus faecalis or Bacillus cereus, which can cause diarrhoea or even food poisoning. What's more, viruses such as norovirus and influenza virus can remain on plastic surfaces for many hours, meaning that transmission through touch is possible even after brief contact.
The reason is simple: hands are the main carriers of germs, especially if they are not washed before or after using the computer. Eating, commuting, sneezing or touching surfaces and then typing transfers microbes directly onto the keyboard. Spilled coffee or crumbs between the keys also provide a breeding ground for bacteria.
Regular cleaning and surface disinfection significantly reduces the risk of transmission.
How to disinfect a keyboard properly: step-by-step
To keep your keyboard and workstation hygienically clean, proper disinfection is recommended. Electronic devices are sensitive, so cleaning must be done using suitable products and methods. Prevent liquid from entering the device to avoid damage.
- Preparation: Switch off the keyboard and disconnect it from the power supply. Remove loose debris by gently tapping it or using compressed air.
- Product selection: Use only disinfectants suitable for electronic devices. Alcohol-based products with at least limited virucidal activity and material-friendly properties are ideal.
- Application: CWS disinfection wipes are practical because they contain the right amount of active agent. Sprays should be applied to lint-free cloths—not directly onto the keyboard. Wipe keys and spaces between them thoroughly. Also clean the mouse and any accessories.
- Post-cleaning: Allow devices to dry completely before reconnecting. This protects both the equipment and users.
For reliable and material-friendly workstation cleaning, we recommend CWS Surface Cleaner, specially developed for sensitive office surfaces.
Embedding workstation disinfection in daily office routines
Regular cleaning routines help ensure a consistently clean workstation. High-touch surfaces such as keyboards, phones, desktops or door handles should be disinfected daily. Of course, taking out the trash as part of your daily routine is also essential to avoid bacterial or viral build-up. Weekly routines should cover windows, shelves and technical equipment to prevent dust accumulation. Checklists and cleaning plans provide structure and transparency, helping everyone know what needs to be cleaned and when.
Placing dispensers, such as CWS Surface Cleaner or Disinfection Wipe Dispensers, at central points like entrances, break rooms or near lifts makes hand disinfection easy and accessible. Defined responsibilities are key: ideally, employees maintain their own desks, while the cleaning team ensures thorough hygiene in the office. Documented hygiene plans support smooth workflows and clarity.
These structured routines play a critical role in maintaining a healthy and productive office environment.
Clean Desk Policy and legal requirements for workplace hygiene
A consistent Clean Desk Policy significantly improves hygiene and organisation in the workplace. The principle is simple: at the end of each workday, the desk is cleared of personal items and unnecessary papers. This allows surfaces to be cleaned and disinfected more effectively, reducing germ spread while improving concentration and productivity.
Legally, employers are required to ensure safe and healthy workplaces. The EU OSH “Framework Directive” 89/391/EEC and Article 153 TFEU provide clear recommendations for cleaning and disinfecting office workstations. Certified disinfectants with proven efficacy play a central role. Documenting hygiene measures is also a legal requirement and essential for compliance.
Hygienic work equipment: improving protection together
Clean and safe disinfection of keyboards and workstations is an indispensable part of a healthy, productive working environment. Only by combining appropriate product choices, clear cleaning routines, a clean desk policy and responsible employee behaviour can germs be effectively reduced and absences prevented.
