Though none of our experts deal specifically with issues related to household odors, I did find two resources that might be helpful from our Extension colleagues in Kentucky and Illinois.  Please go to http://www2.ca.uky.edu/hes/fcs/factshts/HF-LRA.125.PDF for the University of Kentucky fact sheet on household orders.

In addition, the University of Illinois Extension has a link to a comprehensive stain removal guide:  http://web.extension.illinois.edu/stain/staindetail.cfm?ID=23.

Good luck and thanks for contacting Ask an Expert.
