Biokleen Bac-Out Enzyme Cleaner and Stain & Odor Remover for Pet Stains, Laundry, Diapers, Wine, Carpets, & More, Eco-Friendly, Non-Toxic, Lime Scent, 128 Ounces

I like this stuff! Love the clean, lime peel scent.
Good for clearing cat urine stench. Also good for infrequent cleaning of my stinky, sweaty yoga shred mat in summer. I usually use a gentle lavender cleaner made for yoga mats, but a good dose of this got it pristine smelling. I’m willing to chance infrequent mat cleanings with this as needed in future (wipe the yoga mat thoroughly with water afterwards. I’m not sure this stuff is meant for your skin. I had no reaction and my skin is somewhat sensitive, just be safe)I’m extremely sensitive to smells, though I enjoy good smells, high quality perfumes, etc. I detest chemical air fresheners, most scented candles, glade plug-ins, etc. Febreeze is just foul and they all give me toxic allergic reactions.My 20 year old, arthritic kitty could no longer get into her special enclosed litter box that I set up for her in my upstairs bedroom suite where she mostly stayed. She ended up using puppy pads outside the box for the most part.1.5 years of ammonia stink, leaks onto my 112 year old fir wood floor, and puppy pads, bless her. She did her best, my little angel. She passed two weeks ago (and my other kitty manages to use the litter boxes in the basement). So with great relief, I removed the whole litterbox setup from upstairs.During the dotage of two kitties, who have both since passed, everytime I opened the door to upstairs, the stink was there, lingering, stressful, and I now realize, physically depressing. I realize I dreaded going upstairs. But my kitties enjoyed their lives and I loved them, so we did our best, using countless puppy pads (get your puppy pads at Sam’s Club: 120 pads for about $16. Significantly cheaper than anywhere else), expensive electric air filters, and gallons and gallons of enzymatic and oxy cleaners.I used to use Natures Miracle by the gallon in the red bottle. It worked on cat urine, but left behind a very unnatural, lung piercing odor that actually made me sick.I switched to Natures Miracle Oxy orange scented cleaner. I don’t think it worked as thoroughly on the urine, but it helped a lot and I could tolerate the scent. It had a more natural, fresh scent. I bought gallons and gallons of this.Every time I got a new bottle, I kept the aluminum seal on and carefully pierced it maybe 10 times times with a pin, so I could generously sprinkle it on messes, but not waste it by pouring it all out at once. This works really well.So after removing her box the final time, I drenched the wood floor of the litterbox alcove with a half gallon of N.M. Oxy orange and cleaned the wood stairs and everything with the Oxy cleaner.No more stink wafting out when I opened the door to upstairs!BUT still a faint pee pee scent when I went into the alcove. So I ordered this Biokleen lime enzymatic cleaner.It has a strong but pure lime peel scent when you first pour it out. Nothing chemical, nothing offensive to me. Just a clear, clean, gratifying scent that goes away once it dries. And it takes the pee smell with it!I sprinkled about a third gallon onto the 6′ x 6′ area of wood floor, thoroughly wet a Swiffer pad with the Biokleen and scrubbed it into the cracks in floor that had become darkened with pee pee leaks. I kept pouring more on the bad spots to keep the floor wet for several hours. I poured more into those cracks several times over the next couple days. Used over half gallon in the end. My old floors are pretty rustic, and had already been damaged by the pee, so I was willing to risk some minor additional damage to floor. It was worth it to me to get the odor out. Biokleen left a sheen on the wood floor and in the close up picture, you can see the dark areas. Pee made them dark first, and I really dont know if the Biokleen made them any worse, but today, the pee odor is GONE, simply gone. Yes.The Biokleen is good value too, compared to any of the Natures Miracle or other products marketed to pet owners.One more note, I used it on my gel foam mattress topper where my remaining kitty peed, (maybe commenting on his sister’s death). The pee scent is gone, but a fake limey scent lingers. Doesn’t smell as clean on mattress topper as does on other surfaces. It may not be completely dry yet, so I’m turning it over and keeping fans on it during day.

The BEST product for stink removal!!
I’ve used Bac-Out for years, and it’s the BEST – as long as you know how to use it. First of all, it only works on ORGANIC messes. It won’t work on petroleum or chemical based messes. It works great on all the gross bodily fluids (human or animal) like poop, pee, puke, and even “death juice”. Ugh! Second – the reason it works is because of micro-organisms that completely DIGEST the mess — not just cover it up with scent. The micro-organisms in Bac-Out need to be kept alive!! So, make sure you store it properly so the good little buggers don’t freeze or bake. Don’t treat the mess with chemicals (like bleach) before or while using Bac-Out because chemicals could kill the good micro-organisms. Third – it takes a while for the good little buggers to digest all that stuff. So you have to let them stay alive long enough to completely digest the yucky stuff. You should keep spraying it on the area so that it remains wet at all times for AT LEAST 24 hours – longer for grosser messes. If they dry out, the good little buggers will die!I have used this with great success on mold, mildew, baby diapers, pet messes and many other things. But the thing that PROVED to me that Bac-Out is the best is this: (spoiler alert: this is totally GROSS!) An aquaintance of mine (for reasons I STILL can NOT fathom) was storing the remains of his dead dog in a cooler, until he could find a suitable place to bury the dog. God knows why, but the dead dog was in the cooler for years. Ewww!!!!! I told you it was gross! Well, when transporting the cooler, some of the “death juice” leaked out of the cooler and into the carpeting of his car. The whole car reeked of death. It was unbearable. He told me he was going to sell or trash the car. I told him about Bac-Out, and exactly how to use it. He sprayed it on numerous times a day, so that it never dried out, for many days. He was absolutely SHOCKED that it totally worked! The smell was COMPLETELY GONE!! Sorry for such a disgusting story, but it really shows how great a product this is!

I never thought I’d find something to get the smell of cat pee out of my leather couch. Totally worth the money. I was nervous because our couches were expensive but I will buy again and it smells good.

I love this product, however the bottle arrived broken and most of it had leaked out. Very annoying considering the price.
