Your Chicago office might look clean, but true cleanliness goes beyond visible surfaces. Many nightly cleaning services overlook critical areas where germs, allergens, and dust accumulate. This checklist reveals the high-touch, often-missed spots that separate basic cleaning from truly meticulous hygiene.
The Overlooked 12: Critical Cleaning Points
These areas are frequently missed in standard cleaning protocols but harbor significant contaminants:
Chicago's older buildings circulate dust and allergens through vents. Interior surfaces collect layers of debris that blow into your office air daily.
A horizontal surface at breathing level that collects dust, dead insects, and airborne particles that settle unnoticed.
Among the highest-touch surfaces in any office. Studies show door hardware can host 5+ different strains of bacteria.
Touched by every visitor and employee multiple times daily. The crevices around buttons trap skin cells and pathogens.
Refrigerator, microwave, and dishwasher handles accumulate food particles and bacteria from multiple users.
Dust accumulates on foliage, reducing plants' air-purifying ability and redistributing allergens when disturbed.
Light switches and power outlets show visible grime buildup around edges from repeated finger contact.
Adjustment levers, wheels, and bases collect hair, dust, and skin cells in hard-to-reach crevices.
Copiers, computers, and printers have vents that suck in dust, reducing efficiency and blowing particles into the air.
The bottom surfaces of stair and accessibility railings accumulate oils and grime from countless hand contacts.
Shared phones transfer oral bacteria and skin oils. The crevices between buttons are particularly problematic.
Accessed throughout the day with hands that have touched various surfaces, spreading contaminants between departments.
