I love this product and have recommended it to all the pet owners I know. It has worked wonders on house training, I had some really bad and lots of accidents by my dog and thanks to Eco-88, when I left my apt I got my deposit back. I tried every product available for pet stains and odors and then my vet recommended Eco-88 to me and I am thankful they did.
Eco-88 is by far the best product on the market for pet owners. It has also removed stains on my carpet and upholstery, that were not caused by my dog, here is a list of a few stains it has removed. (none of which I had to gentle rub in, in fact Ive never had to rub it in to any stains in my household, though I need reapply but never more than a second time)
Wine
Colored drinks
Body paint
Mud stains
Fish odor (My dog eats whole uncooked fish on my carpets)

Eco-88 has replaced all of my cleaners. Minus the necessary ones, like Windex.
I HIGHLY recommend this product.
