My husband is a super smeller. I find that with certain detergents, we will get what he calls "fish water smell" in glasses that have had water sitting in them for a while. Switching detergents normally stops the problem for a while, but it always seems to come back.
The glasses do not initially have that fishwater quality, but if you let the water sit in them for an hour or so, when you go to take a swig, you get a hit of aquarium smell. It didn't bother me in the past, but the longer I live with him, the more he challenges my nostrils to detect what he can smell, and I now find it pretty offensive too.
This happens other places that just our house. It's noticeable at friends and family's houses too. Any input what may be causing it? I have several different dish detergents under my sink from switching them out as the fish water smell inevitably returns.
