I posted this on the dog side but got to thinking this isn't really pet specific. My dog Disney urinated in the bathroom right on top of the heat and air vent. It ran down inside all over the duct work. I've have scrubbed it with Mr. Clean and then later with Nature's Miracle but it still stinks, especially when the heat runs. What will help neutralize the ordor? This is some potent smelling stuff too.

By the way, Disney has Canine Cognative Dysfunction which is like Alzheimer's for dogs and she is starting to forget her potty training.

Thanks for any suggestions and help.
