Clean is not one smell
Fresh laundry, soap, toothpaste and a recently aired room can all feel clean while smelling very different.
EXPLAINER
Smell & Cleanliness
Cleanliness has a sensory reality and a cultural language. Soap, laundry, citrus, mint and disinfected spaces can all signal 'clean' in different ways.
Culture shapes expectation
Products and habits teach people which smell cues belong with washing, hygiene and order.
Atlas implication
SmellBook keeps 'clean' as a descriptor or cultural association rather than treating it as one universal source.
A clean-smelling space is not necessarily hygienically clean, and SmellBook does not use odor as a safety test.
