Your hands stay stinky even when they’re clean. Such as a fish smell lingers on the skin hours after fishing and labourously washing hands. Why is that?
In: Chemistry
Skin isn’t smooth and try to think about it like it was a carpet. Germs and bacteria are bigger than smell particles.
Drop some relatively big on the carpet, like a coin, and it’s really easy to pick up, leaving no evidence that there was a coin on your carpet. But then spill sand on it or something powdery, and it would take a really long time to really clean that carpet.
