Hello there,

Thank you for reaching out. I understand why you might be embarrassing, but be rest assured that we all encounter things like this at some or the other time.

Since you're a really clean person, it doesn't seem to be you that's causing this issue. One thing that comes to mind - I used to read 'Diary of a Wimpy Kid' when I was young - is that there might be a dead animal or bird stuck somewhere in the walls. You'll be surprised at how animals find their way into random places in homes and unfortunately, poor them, don't find an outlet for leaving.

Have you tried keeping your windows open to let fresh air inside? Ventilation can drive out bad smells and ample sunlight acts as a disinfectant.

If the smell doesn't go, it might be best to hire professional cleaners and try to get them to fix the issue.

Hope it gets resolved!!
