Hello,(halo...) Just a thought .... does there happen to be a floor drain in the room that the oder shows up in??
Hello halo, I just don't see any connection between the odor and what you describe. Perhaps you might try a different approach. Treat the entire area with a specialty product for removing odors. I'm attaching a web site I'd like you to visit.
I've used these products and they have accomplished everything they say about them.
