Biokleen Bac-Out Enzyme Cleaner Spray and Stain & Odor Remover for Pet Stains, Laundry, Diapers, Wine, Carpets, & More, Eco-Friendly, Non-Toxic, Lime Scent, 32 Ounces (Pack of 2)

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.

Good but not perfect. I used this as a pre-spray for a carpet cleaner (Bissell Big Green) and not through the machine. I deal with multiple chemical sensitivities, so I needed something that would wash all the way out. For chemical sensitivity, it's quite good. Note that it does have Benzisothiazolinone which some people react poorly to, but it does wash out with water very easily, so even for someone sensitive to it, if you're going to hit it with a ton of water after it sits, it's generally fine. Otherwise, it's about the safest cleaner I can think of. The smell is massively overwhelming but it's actual lime, not anything that attaches to an oil to glue onto carpet fibers like you get in conventional cleaners, so once it's rinsed, it's gone. Still, nearly removed a star on this because they could pull about 70% off of that smell and it'd still be strong. The spray bottle SUCKS. Other reviewers are not joking. By the time I pulled the spray trigger 10 times, it was dripping down and soaking my hand. Waste of product, huge pain to use. If I use it again, I'll buy a spray bottle and just use the refill jug of this. For effectiveness, I'm kind of mixed. It does do very well removing stains, it is an enzymatic cleaner, but I'm cleaning a rental with old dog pee dried into the carpet pad and while it got the room fresh, if I were to lay on the carpet and sniff the floor, I'd smell some funk still. I'd call it 90% effective. But for something that doesn't bug MCS, that's pretty hard to beat. Far more effective on pet stuff than non-enzymatic cleaners (vinegar, alcohol, etc.) If I had to do it again, I might give odoban a try, but overall, this definitely gets added to my permanent cleaner collection, as long as I'm rinsing with water after to get that lime smell down (it smells terrific, but too much of a good thing ya know)

Yay! It took forever to find an enzymatic cleaner without much fragrance and this is fantastic. I used it to get odors out of automotive carpet and on dog poop/pee stains on carpet tiles. Great product

Buying in bulk is great value for money I have been using for a few months and it is still almost full. It is the same product as the smaller bottles, it smells the same (unscented) but also smells great. It is definitely effective at stain removal. The bottle is resilient and it is easy to use, i use the lid to measure for each wash. I also used it clean my carpet with my carpet washer and it was great for that too. Thanks for the great product.

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.

Used for cloth nappies and eliminating ammonia that wasn't washing out of the night-time ones. Seems to be working well. Much easier to use with the spray head, doesn't seem to foam though but not an issue for me.

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

This stuff is amazing. I have a hallway that was targeted by both my cats and dogs. I tried everything to get rid of the smell. Spent an absolute fortune. I saw this, although I did think it pricey, I thought why not. Best decision ever made. I put it in a spray bottle and sprayed it neat on the floor. Saturated it. Left it sit for a bit then blotted it with a damp mop. Sprayed it again for good measure and just left it this time. I'm absolutely delighted to say that the foosty, dirty, peepee smell is gone. I no longer want to gag and cry simultaneously anymore. Beyond happy.
