Biokleen Bac-Out Enzymatic Odor & Stain Remover for Pet Stains, Urine, Laundry, Diapers, Wine, Carpet, 128oz

The Best by far in elimination cat urine smell in carpet . My sisters cat wasn't house broke yet and the smell from it was bad, even after cleaning it, still had a smell. tried all sorts of cleaners and odoban, nothing helped, even steam cleaned it. This said in description could use in steam cleaner but didn't have too, just sprayed it over section of carpet and let set overnight so it could break up the enzymes deep in the carpet, I put it in a spray bottle so I could spray mist it on carpet.. I called her the next morning and she said she didn't smell anything at all, not even a faint smell of urine. I couldn't believe it, so rode over and sure enough , there was no smell and it was bad even after all the previous cleanings, this stuff works great like a miracle, Now I can visit her without all the cat smell.
