I was truly amazed that this product not only worked, but worked so well. My problem was mostly old stains that would re-surface after having professional carpet cleaning done. And those guys always recommended doing an enzyme treatment for pet stains (and they charge more for that) and tell you that our stains will disappear, etc, etc....
I had the professionals come out about 3 months ago, and within a month the stains were coming back up. I typically would use Resolve Foam, and get down on my hands and knees and scrub. So when I learned about this product, I figured I had nothing to lose to try it out. I'm still amazed at how well it does whatever it's doing. I will keep this product in my home for as long as I have carpet in my house.
