Most office cleaning focuses on visible surfaces — desks, floors, maybe the break room counter. The spots that actually accumulate the most germs are usually the ones nobody thinks to wipe down.

Shared touchpoints see the most hands

Door handles, light switches, elevator buttons, and the shared coffee machine get touched by nearly everyone in the building, often dozens of times a day, and rarely get cleaned as frequently as a desk does.

Phones and keyboards trap what hands carry

A personal desk phone or keyboard isn't necessarily worse than other surfaces, but because it sits close to the face and gets touched constantly, whatever's on your hands ends up there too — and stays there until it's actually wiped.

Break rooms are busier than they look

Microwave door handles, the fridge handle, and shared condiment bottles get touched by everyone who uses that space, usually right before or after eating, which makes them worth more attention than they typically get.

None of these spots need constant attention — just more of it than they usually receive.
