Need help with horrible dog smell
I have a vacant apartment which reeks of dog odor. It is not urine/feces, just the smell of a dog which was never bathed. The entire place has been painted, including the first floor ceilings. The carpets have been professionally cleaned. I even called a disaster recovery place and got some stuff that they use for smoke damage, etc. It is supposed to have bacteria that eat the source of the problem. I sprayed the carpets and part way up the walls with a fairly concentrated dose of that, twice. Still the odor lingers.
The downstairs has prefinished hardwood floors, which have been mopped twice, once with vinegar and once with household cleaner. I'm afraid to use anything too harsh there.
Any more suggestions? I am afraid I will end up replacing the carpet, but I'd like to try anything else first. I need to get to the source, so things that simply cover up the odor won't work. I've tried.
