Well, if nature miracle worked, my living room rug wouldn't be outside right now. With that, I DID find something recently that worked fantastic!!! I found it at Lowes and it's called "Home remedy PLUS, pet stain plus odor eliminator", WOW!
Back story, I've been wanting to haul the living room rug out of the house for over a year now and power wash it, my mother didn't seem to want to believe me that it smelled like pee in front of the sofa. Needless to say, she got into a game of ball with Enda and as usually End stuffed her ball under the sofa, my mother bent down to find and, all I know is the next thing I heard was the thud of her rolling up the rug, I WON! Except, the first "treatment" to clean to rug, made it smell worse, the second, didn't remove the new odor either and left it reeking of lavender, the third, talk about salad dressing (wont be playing with Vinegar again), but I was looking around at Lowes for ANYTHING! Well, I know you shouldn't buy based on price, but this stuff looked the best and was the cheapest so I went for it. Yeah, next time I'm in the store I'm buying up the entire display! Does that tell you anything?
