Bests & Worsts Reviews from Amazon

We have three German Shepherds who are (evidently) winning some sort of elimination contest. We pick up daily but you can't pick up urine. By end of Summer each year, it's a nightmare. I was concerned that Simple Green would not be strong enough to make a difference but this is not the same formulation as the Simple Green cleaners. We applied this with a garden hose and one bottle was enough for the whole yard and our patio. IT IMMEDIATELY REMOVED ANY AND ALL SMELLS. I thought perhaps it would wear off quickly but it remains odor free. I'm going to treat weekly and I'm now a convert. Works better than anything I've ever used.
