Review on EARTH FRIENDLY Ecos, Pet Odor Remover: Powerful 22 Fl Oz Solution by Kelly Slevira

I don't know about stains because I use it on black carpets, but it really helps with the smell. I have an older kitten who decided to pee and poop on the carpet in our living room. At first I was disappointed because this product didn't get rid of the smell after a treatment or two. It actually took over five treatments for the urine smell to go away from our carpet, but in the end it worked, and very well. All it takes is persistence and a few treatments. However, that won't stop your kitty from going about their business in this place. But it will help you clean. If it had magic pollen to prevent cat pee, this would be the perfect product.
