I have to be honest, I don't know if this actually works yet - but I will update! However, in case anyone else is having the same problem as I am, I wanted to put up this review ASAP. I take in older and special needs animals, and one cat peed outside the box and suddenly the boys (3-4, all neutered) started having a massive pee war that was impossible to keep up with. One of the reasons it was impossible to keep up with was that our relatively new carpet that I just replaced two years ago appeared to be reacting to every enzyme cleaner I tried - two versions of Nature's Miracle, Biokleen, Skout's Honor, Anti Icky Poo, Stink Free, Urine Off and Nok Out (and one or two others I can't even remember), the latter four of which come HIGHLY recommended in the rescue community. Every one of those bleached the carpet in the exact spot where urine (or vomit) was, with the exception of Nok Out, which did the inverse of this - left the pee spot unbleached, but bleached the outer 34;clean34; edges. In the meantime, our house became... something of a urine pool. I had accepted that in order to properly clean the pee, it would mean having to sacrifice my beautiful new carpet and learn to live with massive bleach spots on nearly half of it throughout the entire house, and accept that I would have to pay to replace it whenever we move (this is not our 34;forever home34;). I was heartbroken and devastated. Then I remembered an old episode of My Cat From Hell, and Fizzion came to the rescue. So far, it has NOT bleached our carpet!!! We've been working on a section of about 6-7 square feet in the bedroom for the past week. Since we know it's the worst section, we've been cleaning thoroughly by spraying, then blotting, then letting air dry completely, repeating that exact process 3 more times before then SOAKING the entire thing in order to get better coverage and most importantly, get down to the pad. No discoloration whatsoever! Yay! Once we get through the whole house, if it appears to be working, we intend to steam clean with the steam cleaner version of Fizzion. So far, we do think it's 34;working34; otherwise. My boyfriend and I are not the best sniffers, which makes it more difficult to tell, though it's clear it does not evoke an immediate 34;OH GOD YES, MY NOSE IS ABSOLUTELY TOUCHING CAT PISS RIGHT NOW34; response like it used to... more like a 34;IS that pee that I smell? Or is it the cleaner? Am I just smelling the carpet? I have no idea what I'm smelling right now if anything at all34;. That has to be progress though, right? We are also using a blacklight and the spots we've worked on seem to be drastically less flourescent than they were before (though I'm uncertain of how much it's supposed to affect the stains under the blacklight), but we'll know for sure if we can keep our biggest culprit from returning to the biggest problem areas. I'll update when we can better guage that. I'm not sure about the stain removing ability because none of our urine spots have stained the carpet. Or maybe we just can't see it because our carpet is a darker grey. We did use it on some vomit on the cream colored part of our area rug and it lifted what was there well, but we attended to that immediately after it happened, so that could be why. The scent of Fizzion itself is on the milder end of these type of cleaners in my opinon. For now, I'm leaving it with this rating for the simple fact that it is enviormentally friendly compared to other competitor's, is safe for pets, and DOES NOT BLEACH THE CARPET!!! For anyone else dealing with this problem, we obviously at some point realized the issue was with our carpet and not the cleaners, and we've talked to one local flooring guy who said that sometimes the dye can react to the enzymes somehow (which I assume is why the CO2 in Fizzion doesn't react the same). It must be somewhat rare though, because I didn't find anything about it online and could hardly find anyone else (online or otherwise) dealing with this when I was searching for a solution. Hopefully my review will help anyone else going through this though because it is so disheartening and potentially very, very costly. You are not alone or crazy! Try Fizzion!!! To be updated!
