Said It Here

Why is there a mystery wet dog or sour smell in the house?

An unexplained, lingering odor resembling wet dog, sourness, or sweetcorn transfers unpredictably onto household fabrics in rooms like the bedroom, leaving people unable to trace its source. Because the smell appears in random places despite no obvious cause, it prevents occupants from successfully eliminating it.

Noticed a really strong urine smell coming from my sixteen year old baby’s head today. Gave her a little wash and it still persisted. Any advice?source ↗

Recently, I’ve noticed this really disgusting wet dog/egg-like smell on most of the dishes.source ↗

I’ve even tried being extra thorough, but the smell still seems to be there after it dries down a bit.source ↗

It’s honestly driving me insane 😭 Has anyone experienced something similar or have any idea what could be causing it? And what can I do to get rid of it?source ↗

I just bought a home a month ago and have been noticing a trash-like smell immediately when walking into my house and upon passing the front door landing.source ↗

It is not constant and seems to correspond to days with higher humidity.source ↗

Will that fresh minty smell go away after it dries?? I can’t use it if it doesn’t.source ↗

Google tells me once it dries and finishes the enzymatic process it should be odorless, but I don’t exactly trust that hahasource ↗

Today we tried to cook some food, and once again the smell was back. It was working, blue fire, sometimes orange here and there, but the smell is horrible.source ↗

I could also describe it as maybe like stinky feet, maybe kind of sour.source ↗

I've started smelling it in the bedroom somewhere.source ↗

I'm just completely at a loss to understand even if it is dog smell why is it happening in seemingly random places.source ↗

We have one specific section of our basement that smells terrible, and I cannot figure it out.source ↗

Thought it was cats peeing, so I walled them out of that area, scrubbed the floors with a bleach mixture, sprayed an odor eliminator all over, and it just smells like it always did a couple weeks later.source ↗

Earlier tonight, I started to smell lighter fluid coming from my car.source ↗

I don’t use zippos so I definitely know it isn’t from actual lighter fluid.source ↗

Currently not driving my car until I figure out the issue.source ↗

The pipes under my sink and in the boiler room stink, it’s a horrible smell. It’s very sweet but almost like sweetcorn.source ↗
