Office Kitchen Cleaning: Hygiene in Shared Spaces

The office kitchen is a shared space where the hygiene habits of dozens of people collide. It is the highest-bacteria spot in the entire office — yet it is also the most commonly underestimated area when it comes to cleaning. Here is a guide to getting it right.

Why the Kitchen Is the Highest-Risk Hygiene Area in an Office

Studies consistently show that the office kitchen contains more bacteria than the bathroom. The combination of moisture, food residues and heavy use creates ideal conditions for microorganism growth. The highest-risk spots: kitchen sponge (replace at minimum weekly!), sink and taps, fridge and microwave door handles, and the coffee machine button and machine itself.

Daily vs. Weekly vs. Monthly Kitchen Cleaning

Daily (employees or cleaner)

• Washing up or loading the dishwasher
• Wiping the worktop
• Taking out the rubbish
• Wiping the sink and taps

Weekly (cleaner)

• Cleaning microwave inside and out
• Cleaning the coffee machine (descaling, forced flush)
• Disinfecting the sink and taps
• Replacing the kitchen sponge
• Cleaning the exterior of appliances
• Mopping the floor

Monthly (cleaner)

• Cleaning the fridge interior (checking for out-of-date food)
• Defrosting the freezer (if applicable)
• Cleaning the cooker hood or ventilation grille
• Cleaning cupboards and drawers inside
• Cleaning fridge door seals

Most Common Problems and How to Solve Them

Mould in the Fridge

Out-of-date food and insufficient air circulation. Solution: monthly check, a clear rule for employees (label food with a date), and monthly cleaning of drawers with a disinfectant product.

Smell from the Bin

Rubbish must be taken out daily. The bin should have a liner — without one, disinfecting the bin is extremely difficult. Disinfect the bin once a week.

Limescale in the Coffee Machine

Prague water is hard — the coffee machine needs descaling every 4–8 weeks. Neglected descaling shortens the machine's lifespan and deteriorates the taste of coffee.

Employee Rules: What Works

Kitchen cleanliness does not depend solely on the cleaner — it also depends on company culture. We recommend simple, visual rules displayed in the kitchen itself: "Wash up after yourself", "Label food in the fridge with a date", "Throw away out-of-date items". Rules must be clear and visible — not hidden in the internal wiki.
