Bac-Out Carpet Cleaner Spray, Stain Remover and Odor Eliminator, Use on Area Rugs, Upholstery & More, Removes Dirt, Pets, Wine & Food, Lime Scent, 32 oz, 2 Pack

It actually works. I have two rescue dogs that are now 17 years young which have begun to have occasional accidents. I do clean after each accident, but I was afraid if they smelt it in the carpet, they’d continue to go there instead of selling me to let them out. This Biokleen Bac-Iut Enzyme Stain and Order remover completely took it out. I did have to clean a couple of times as with the blue light I could see where it wasn’t quite gone. But after two cleaning (spray soaking, resting to dry point, then shampooing it out), it’s completely gone. All stains, all smells, all fears are gone now. The proof is in the fact that they came, sniffed around without focusing on an area, and left. There was no discoloration on my area rug, no stickiness left after spraying or shampooing. The fresh smell lasts a very long time (so far 24hrs), and no sign of lingering scent for them to grab hold of. It comes out very easily in my spray bottle without leaks (sometimes if it’s too watery the bottle will leak no matter what you do). Of all the order eliminators I’ve tried, this is the absolute best. To be honest, they could charge more and I’d paid it. This is one product that’s truly worth every cent spent on it. Key thing is to do exactly as they say in the directions. Vacuum, spray to point of saturation, allow to completely dry, flip rug (if possible), spray other side, dry, then clean the entire carpet (they didn’t say that, but I simply couldn’t leave that in my carpet even if it truly eliminates it. The thought wouldn’t allow it😖). For sure, you won’t regret your purchase. I very highly recommend this product for removal of milder smells as well as pet accidents.

I’ve been using the 128‑oz Biokleen Bac‑Out Enzyme Stain & Odor Remover for a few months now, and here’s my take from real-life use: ⸻ ✅ What I Love • Effective on tough stains and odors It tackled old pet stains on my carpet and even wine drips on my couch. After letting it sit, the spots and smells disappeared without me having to scrub madly  . • Safe and eco-friendly No harsh chemicals—plant-based, biodegradable formula with live enzymes. It’s certified by Green Seal for safer cleaning . Great for a pet-filled and kid-friendly home. • Fresh, subtle scent The lavender-lime scent is mild and pleasant—no chemical bleach smell. Even better: it disappears quickly, leaving things smelling neutral . • Multipurpose cleaning I’ve used it inside my washing machine for sweaty gym clothes, on carpet spills, upchuck from my cat, and even diaper stains. It’s tackled them all successfully . ⸻ ⚠️ What to Know Before You Buy • Use enough and let it work You need to saturate the stain and let the enzymes dwell for at least 10 minutes—longer for deeper-set messes. Wiping it too soon cuts effectiveness  . • Big jug, big space The 128-oz bottle is a bit bulky, so I ended up transferring some into a smaller spray bottle for spot cleaning convenience . • Some shipping issues A few buyers mentioned leaks during delivery. Mine arrived okay, but worth knowing if your bottle comes via mail . ⸻ 🧭 Final Verdict If you’re dealing with organic stains—like pet mess, food, wine, or workout clothes—and want a safer, eco-friendly option, this formulation really delivers. Just use it as directed (saturate and wait), and be aware of the bottle’s size. In short: powerful, plant-based enzyme cleaner that works across multiple mess types—just give it a bit of space to work, and maybe prep a spray bottle for ease of use.

I’ve been using this product for years in my laundry. If you have any odors, it’s a must! From musty odors to animal waste to body odor, Bac-Out will eliminate it. I’ve recommended it to dairy farmers who now swear by it. I’m chemically sensitive and this product is great. It doesn’t cover odors, it eliminates them. I haven’t used it on stains but I wouldn’t hesitate to give it a try.

This is it. This saved my girlfriend’s mildew ridden car. To prove this isn’t a fake review, I will disclose I wet my bed every night except I don’t, not really. Long story short, we bought a car with an insane mildew smell that I assumed ozone or chlorine dioxide would fix. Neither worked. I ended up tearing the car apart—literally. I removed padding, cleared all trapped water, then ran ozone and chlorine dioxide again. It still smelled. The mildew had sat so long it coated everything—under the dash, deep crevices, places you can’t reach without full disassembly. The carpet itself was soaked, including the rubber backing, which had been in contact with moisture the longest. I genuinely thought it was unsalvageable and started shopping for replacement carpet. Local options were nonexistent, and junkyard carpets were in bad shape. As a last attempt, I sprayed this product on the interior, soaked the rubber backing, then shampooed the carpet with dawn detergent after letting it sit overnight. It 95% erased the remaining mildew smell. Per their guide, soaking overnight (or at least 30–60 minutes) and then air-drying with a fan is key. There were still a few areas I had to physically remove—like seam caulking in the metal body, which can harbor mildew and must be cut out and replaced—but this product ended a month-long nightmare. I have genuine love for this product and would recommend trying it before anything else. That said, my situation was not typical. This was an extreme case. An ozone generator or chlorine dioxide bomb alone might work for most cars. Mine had a sunroof leak and a bad rear trunk seal or torn rubber molding—two active water intrusion points. The previous owners apparently just lived with it. It was absolutely insane.

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.

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.
