The Neutralizer

Considering if the rain is purely water, it shouldn’t have any sort of smell attached to it. If anything, if the rain does have a scent, it is most likely due to potential minerals inside of the rain or the runoff when the rain is on the ground. I would say that rain and the moisture of the air would be more of a feeling rather than a smell. In a way one could say that rain could be a neutralizer of smell. Oftentimes, the police use dogs to smell out where someone or something is and when it harshly rains it can wipe away the scent thus in this situation the rain acts as an anti smell.
