  • I like this stuff! Love the clean, lime peel scent.
Item Package Quantity: 1
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. ... show more

  • Very Excellent Product!
Item Package Quantity: 1
Update: as a test, I ordered Odoban’s equivalent to BioKleen. I applied the same process to a pet pee spot. Nope! It did not work. The Odoban was $11 cheaper but it did not take away the pee smell. Took the stain away but not the odor. Sticking with BioKleen! Where do I start..? I have two dogs. One is a senior and the other is a puppy. As you can imagine, both have accidents in my house. Wish they didn’t but they do. My carpet in my bedroom takes a beating from them because that’s where they hang out at when I’m at work and of course they sleep with me so they are in my bedroom throughout the night. Needless to say, my carpet can be a little stinky at times. Drives me nuts but I love my dogs. What to do… Sigh. 🤷♀️ I searched Amazon for a cleaner to help get the odor out and came across this product. I read the reviews and decided to try it. I appreciate everyone who did write a review. It’s so helpful when buying a new product. I heavily sprayed my carpet with BioClean enzyme carpet cleaner. I poured cleaner on a pee spot too. Wanted to make sure it soaked into the padding underneath. I then let it dry. I walked into my bedroom after a few hours and I couldn’t smell pee pee. Yay!! Then I used my new Turbo Pro Heat machine with the Bissell anti-bacterial cleaning solution. Set my machine on Max Clean and went to cleaning. When done, my carpet looked beautiful and no pee pee smell! Winner!! Highlights: 1). An ever so light lime fragrance when smelling it in the bottle. No fragrance when applied to carpet. 2). It definitely neutralized the pee pee odor from my two dogs. 3). I have light colored carpet, it did not stain or bleach out my carpet. 4). No citrus smell after cleaning. Period. Just clean air smell in my bedroom. Same the next day. 5). Highly recommend. Especially if you have pets that have accidents on your carpet. Put it in your cart and hit the Buy button. You won’t be disappointed. 👍🏻. ... show more

  • Neutralizes the urine and vomit from carpet

My Schnauzers have really sensitive stomachs and frequently vomit and/or have accidents on the carpet. This works great in my carpet shampooer and removes the odor as completely as anything I've used

I just LOVE this pet stain and odor remover! I assumed I'd tone down the ammonia urine smell on my reusable puppy pads. This treatment solution eliminated the odor altogether, AND it removed the stains. It's the first pet stain remover that actually removes stains and odors. The pictures I added are reusable puppy pads that I use for my rabbit. The mixture of sometimes missing his litter box along with hay residue pushed into these fibers made me think there's no way this will come clean. But then look at the clean puppy pad picture! It looks brand new! And it smells fresh! Unless I showed you the condition they were in prior to treatment, you'd never know about any of it. I decided to try this solution on other problem fabrics. My husband, bless him, hangs up worn clothes in his closet. After many months, he smashed these dirty clothes into a hamper, and since he only likes washing 1-2 loads of clothes, the dirty fabrics remained packed into the hamper of a closet. The smell was terrible! I tried Oxyclean, Shout, and Tide stain and odor remover. It did nothing. I washed the garments twice, and they still had that stale smell. So I soaked them in Biokleen pet stain and odor remover. I soaked the clothes for a full 24 hours, and then I washed as normal. They came out like they were brand new! They smelled amazing, and the colors and whites were more vibrant. Hands down, the best stain and odor remover! ... show more
