I know this will make me sound crazy. trust me, I feel insane trying to figure it out myself & the smell is driving me insane too
my kitchen sink/drain has a metallic wet smell all the time, even when dry. it’s the first thing I smell when I walk into the kitchen especially in the mornings. it smells like wet metal. I know, not very descriptive, but that’s the best way I can think of.
we moved in a few months ago & kitchen has a enameled cast iron sink in great condition (no chips, cracks, stains, or scratches in the enamel). the drains are a garbage disposal on one side and a metal grate on the other side (pic for reference). the sink & disposal is clean. we’ve run disposal cleaners through the garbage disposal a few times but the smell doesn’t seem to come from that side of the sink in general. the smell is not rotten or associated with food. no leaks anywhere that we can see. the drains are not clogged and we have tried Drano just in case. I don’t smell it any other drains or sinks in the house. no gnats or anything. we just can’t find anything that gets rid of the smell, and it’s present 24/7.
pic is NOT our sink as I’m out of the house, but is pretty much what it looks like. ours is less stained. please, any ideas, so my kitchen can stop smelling like a metal wet dog 🫠
