I guess they mean that most people can smell freshly sprayed cleaning products but think the products don't smell of much when still in the bottles.
The aisle has a faintly bleachy/detergenty smell to me, but not usually oppressive, more just pleasantly clean, I suppose.
But I have noticed my hands/sweat smell different when I have a cold, and sometimes a day or two before I feel ill. I usually only get close enough to notice it on my own body, but I have a couple of times entered someone else's room/office and smelt the same smell before hearing confirmation from their croaky voice, snuffling, or them just telling me they have a cold.
(And no, it's not the smell of cough sweets or lemon/honey-based cold remedies, but it might be partly the smell of damp tissues and stale phlegm and other such nice things. Subtle but sickly sweet.)
Obviously this is neither particularly useful nor a superpower, but I'm glad research is going on into more useful applications of similar phenomena.
