– Bac-Out - Carpet Cleaner Solution - Enzyme Odour & Stain Remover - 3,8 L

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.

This product hasn’t worked for us and we have found much better products.

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.

TLDR: Buy this. It's magical. And it smells wonderful (limey). See pics -- total time (stain to clean: 2 LITERAL minutes!) BIOKLEEN (Magical Witchcraft Potion): I've used this product for years (multiple critters in the home), never writing a review before this. Recently, Thing One decided to start throwing up his food and I learned that food turn a bilious bright yellow when it comes back up. All my light colored carpets are where he prefers to throw up (not the hardwood floors). Thing Two is experiencing some kind of gastrointestinal disturbance and is leaving little piles of love outside the litter, again, on the light colored surfaces. Enter Magical Potion (BIOKLEEN). This will seem like an exaggeration -- all I can say is try it for yourself. LITERALLY, I sweep/vacuum up whatever has dried and can be removed. Then, I wet the stain with BIOKLEEN. The first time I got busy with laundry and forgot to return to scrub after spraying, and guess what? IT WAS GONE. The stain was LITERALLY GONE -- no scrubbing, no panting, no cursing, no hoping. This stuff literally ate it up! I was astonished and it was too late to take a pic. So this time, I've shared the TWO MINUTE process in pictures. From stain to gone (one minute 56 seconds). I did use that siliconey scrubbie looking thing, but it wasn't necessary. Magical. One Caveat: I got overexcited one time and poured the liquid from the jug (instead of spraying). I would not advise this on carpets. It worked spectacularly to remove the stain (again, no scrubbing) BUT, I think it became OVER-SOAKED and when it dried, the carpet (a large 10x12 ft) was ever so slightly bumpy in the surrounding area, as though some fibers stretched out or shrunk during/after the soaking. Sort of like when you get sisal or jute wet and then it never lays flat again). So -- long/short: Buy it, use it, SPRAY it (don't jug-it), and love it. :-)

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!

My bottle arrived with the seal in tact and the cap on but it was leaking. Not much came out so I didn’t bother to return it. I have no idea how to really use it. So I filled the carpet cleaner machine with 1/3 cleaning solution and 2/3 water. I went over the pee stains a few times and then let it sit for 10-15 mins. Then I used the dry only function on the carpet cleaner. ALL THE STAINS ARE GONE!!! 100% GONE!!! My room smells so clean. It’s not a strong odor but it’s pleasant. I would like better instructions for the carpet cleaner. And I was a little disappointed it leaked. But I have never used anything so effective before and I have tried ALL the products. As another reviewer mentioned, Natures Miracle used to be amazing and now it sucks. This is gonna be my replacement for that product.

My male cat has always had issues with marking outside the litter box but the problem really skyrocketed when we moved into a new house and got a new kitten. Suddenly he started peeing on the carpet all across the house which he never used to do. I tried literally 6-8 different cleaners (can't even remember how many at this point) to get the smell out, including some of the most highly recommended ones, but nothing worked to get it out completely even after treating the area multiple times. I could still smell it if I got close and he certainly could as well because he kept re-marking the same spots. I was on my hands and knees scrubbing the carpet almost every single day and I was completely at my wit's end. After yet more research I saw this cleaner being recommended in a few different places and decided to give it a try, even though it was a bit pricey and I had basically no hope left. First of all it smells really good, definitely the best of all the cleaners I've tried: a light, pleasant lime-y scent. But more importantly...it WORKS! I was shocked when I used it on one of the spots and it completely took the smell of urine out, even when I stuck my nose in the carpet to see if I could still smell it. It literally kills the stench completely, you can tell a night and day difference just walking into the room after cleaning with it. Even a week later I can still smell the cleaner on the carpet but in a GOOD way, it just smells nice and clean. As I treated all the spots throughout the house I found that it took care of 95% of them on the first treatment. Only a few times did I have to treat a spot twice, which is a small price to pay. But I know it's working because my cat is no longer going back to mark those same spots even several weeks later!!! Hallelujah!!! This cleaner, along with a special brand of litter to attract cats, has cut way down on my cat's accidents. I know he'll likely do it again at some point but I no longer dread it as much now that I have this cleaner in my arsenal. I only wish that I had started with this one because I could have saved myself a ton of time and money!
