Did you deep clean the furniture too, some times it comes with attatchments for the furniture, or maybe at the store they have some kind of cleaner that cleans in the carpet upholostry sprays in the area by the carpet cleaners or cleaning supplies. Also I have used tuff stuff that is in the automotive section, it cleans good, but I would test it first in a small spot to make sure it don't change the color, and don't put it on objects that it will strip finish off. Mostly for upholstry in the car fabric and vinyl.
Can get odor eliminators as well that come in a jar.
Also if you use lysol spray every day through out the house kills the odors bacteria and germs. I have used that many times on fabrics. Also in the nursing homes we used it every day through out the house.
