“when someone is clean, you can smell them before you can see or hear them a lot of times”
if you can smell something that is clean, I would argue that it is not clean at all, after all you cannot smell nothing.
(yes I know that some people claim outer space smells bad, like polycyclic aromatic hydrocarbons)
I guess you’re just arguing semantics at that point. By clean, I mean what most people think of, meaning dirt, oils, sweat, and everything else washed off the body with water and cleaning agent of some sort, like soap
