The 10 dirtiest places in an office building (that most people never think about)
As a commercial cleaning business owner, I notice things most people walk right past. Some of the dirtiest spots in an office aren’t the obvious ones.
Here are 10 places that tend to collect the most germs and grime:
1️⃣ Door handles and push plates – Everyone touches them all day long.
2️⃣ Light switches – Rarely cleaned but constantly used.
3️⃣ Breakroom appliances – Microwave buttons, coffee machine handles, and fridge doors can get pretty gross.
4️⃣ Shared keyboards and phones – Especially at reception desks.
5️⃣ Elevator buttons – Hundreds of touches every day.
6️⃣ Restroom stall locks and handles – One of the most overlooked areas.
7️⃣ Sink faucets in kitchens and restrooms – High touch and often missed.
8️⃣ Office chairs and armrests – Fabric and vinyl hold oils, dust, and germs.
9️⃣ Baseboards and floor edges – Dust and debris build up over time.
🔟 Air vents and return grilles – Dust collects here and affects air quality.
A good cleaning company doesn’t just clean what people see — they pay attention to the small details that help keep workplaces healthier.
Sometimes the cleanest-looking offices still have the most overlooked spots.
If you work in an office, take a look around tomorrow… you might notice a few of these. 👀
