We bought a 1950 rambler as a rental from original owners 2 years ago. They had lived there 60 years and had no pets.
There is still a smell associated with it that we can't get rid of. We've removed all wallpaper and repainted every surface, took out all carpet and resanded floors, had the ducts cleaned, and tried every odor-removing product we can think of. We've also had it inspected for mold but none was found. It is a single-story house and the smell isn't in the attic space or the semi-finished basement - just the main floor. We live in the Midwest and the smell does not seem to get worse or better with changing weather.
Yet there is still that "old person" smell in the house -- and to make it worse, it attaches to anything that we bring in there - even if we're there or our kids are there for a few hours, the smell is on our clothes or hair after. If I wash bedding from there in my house, the smell is still in the bedding after -- although less intense and if I keep the bedding at our house and put dryer sheets directly on the bedding, the smell will eventually go away.
The people who moved out live in a retirement community, and we're told that the smell is still present in their things even after two years.
What else can be done? What could be causing the smell?
