I live in a house built in the 40s. It has a distinctive smell that I call "old house smell." I've noticed a similar smell in other old houses. It's not necessarily a terrible smell, but i would like to change it. It can be altered somewhat by air fresheners, etc, but it never completely goes away. I'm sure those old houses that are rennovated on tv don't retain that smell, but unless I gut the house and start over, Is that just something I'm stuck with?
