There is a question on main which asks how long a scent can remain tracable.
I personally feel like this question is off-topic since there seems to be no reason why this question couldn't refer to a mundane, real life scenario. There is nothing for us to add that chemistry.SE couldn't do better.
I'm not 100% sure though and feel like it's valuable to discuss these edge cases more explicitly, so we can make a more confident decision the next time around. I'm also not entirely sure if this specific question could be rewritten to be more on-topic.
How does the community feel about this question?
