Biokleen Bac-Out Pet Stain Remover - 2 Gallon - Enzymatic, Natural, Destroys Stains & Odors Safely, for Pet Stains on Carpets - Eco-Friendly, Plant-BasedGreen SealGreen Seal

Why did you pick this product vs others?:I was having a problem with my two male older cats spraying in my house. Nothing I had could get that smell out. My carpet cleaner guy told me about biokleen Bac-Out and I got the one specifically designed for pet odors and stains. It was fabulous! It’s the only thing that got the smell out. It took a few applications - I’d saturate the areas and let it dry and apply again Ihad to be patient, but I finally succeeded, and now the spraying situation seems to have resolved itself.

We had an unfortunate incident while out of town— our pet sitter used the bathroom in our basement bedroom and didn’t close the door to the bedroom all the way. Three of my dogs went into the one room in the house with carpet to lay down and the fourth (and arguably dumbest, bless his heart) closed the door trying to get in with them. Pet sitter went on about her day (my dogs are pretty self sufficient with dog door, automatic feeder and infinite water supply) and fell asleep at her boyfriends blah blah blah long story short we’ll never be calling her again and my dogs were trapped in the basement for god knows how long. A golden retriever, a German shepherd and a Great Dane all with full bellies and a toilet that runs and runs and I’ll let you guess what we returned home to. Thankfully their digestive tracts went easy on us but you may recall me mentioning a toilet that runs…. I don’t know how many gallons of piss were produced but I can tell you I don’t wanna talk about it ever again after this review (and won’t have to thanks to the product in question!)First step was to get rid of the excess urine. Enter: carpet cleaning machine that will never look at me the same way again. Sucked up what I could and then misted some of the dried areas with plain water to get it to suck up again.I suggest for this next part you source some inexpensive white bath towels. I went to the local Wally World and picked up $60 of their $2.97 white towels for this job. Once you get the stickers off of them, toss them in the washer on just a rinse/spin cycle. Take the damp towels and throw them on the carpet and walk all over. For large areas, get creative but the intent here is to weigh down the towels so that they wick up whatever moisture is in the carpet. When the towels are yellow, you have soaked up the majority of the pee. Take those towels and throw them in the wash and wash with hot water and a little detergent— NO BLEACH (not yet). If the towels are absolutely atrocious you can bleach them but they must and I mean MUST be washed again with just plain water after. Bleach is not your friend here.Get a pump sprayer, and start spraying your spots. Soak them. I mean saturate the heck out of them. If you can’t get into the padding, grab one of those turkey injectors and go to town. I have a carpet brush that is for removing dog hair. It’s a silicon bristle on one end and a squeegee on the other. Spread it around, work it in. Now go get those freshly washed damp towels and cover every inch of treated area. Now wait. If the towels dry out, get some water in your sprayer and mist the top. Now wait some more. If it’s wet, the enzymes are doing their thing. If the towels get gross, rinse and repeat. Once the smell is gone, wash those towels real good and then cover again, this time applying pressure to suck up the rest of the cleaner. You can also do a hot water rinse with your carpet machine and cover with towels if it’s real bad.Now for the final and arguably most important step if you ever want your carpet to feel soft again. If you have ever used carpet cleaners, they are incredibly basic. As in the alkalinity of the cleaner is what gives it the ability to lift stains from the carpet. You know how bleach is extra slippery compared to water? Now you understand why your dried carpet feels crunchy and slippery. How do you neutralize it? Well the simple solution is a 50/50 mix of hot water and cleaning vinegar in your carpet machine. The acid will neutralize the cleaner and allow it to be sucked up from the carpet. The only downside to this is that the lime essence that this product will provide will now smell like a pickle factory, but don’t worry. The pickle smell will go away and you’ll have nice soft carpet. Oh, after the vinegar rinse…. Those towels you just cleaned get one more use. Let them soak up as much as that vinegar bath as possible. If you have older carpets it’s possible you’ll get what’s called browning— look for a product called a “Brown Out” on Amazon and that should help.Godspeed!

Why did you pick this product vs others?:Fabulous product!! I love that it actually removes hard water stains that have been impossible to get rid of with everything else we’ve tried AND it didn’t have toxic fumes! Definitely worth the money spent!

Took a cpl applications. But I definitely helped the horrible smell.I will buy more when needed . And the dog is now wearing a belly band when we leave.

Great to have something that works so well and quickly when needed! Leaves no stain and definitely takes away the smells effectively and quickly.

Este producto es súper recomendado, elimina los olores rápidamente de la orina de mi gato en cualquier superficie que haya sido afectada.

Very happy with this product. I had a cat who decided that she no longer liked her automatic litter box and was urinating in the closet and entryway. It was truly pungent! We tried several products before finding this one. It took a couple applications, but we cleaned it up and the smell is gone.

I have 5 cats, and 2 of them are in a pee contest. When I tell you I have tried all of the pee cleaners, I really mean it. This is the only one that truly worked the first time on not only removing the smell but the stain. Yes it is pricey, but put it in a spray bottle and it will go a lot further.
