I know they sell a bottle of something for pet stains and odors, I seem to recall that the guys who cleaned the carpets at my fathers would just add something to the water in the machines….and I want to say it was some common thing, like ammonia, or bleach or something…a very small amount…

Anyone have any ideas – or suggestions?

I cleaned the spot as best I could with paper towels and spray bottles of carpet stain remover….but it still smells yucky….
