A spray-and-walk-away formula with the bamboo-and-mint scent owners rave about.

What wins people over with this one is the scent — 99 owners mention the bamboo and mint blend positively, making it the most-praised aspect of the bottle. It’s a fraction of the Nature’s Miracle jug’s weight at 1.74 pounds, so it’s an easy grab for quick cleanups. At 24 fluid ounces, it’s a focused spot cleaner rather than a whole-house solution.

This is designed for true no-scrub cleaning. The enzyme formula lifts urine, feces, drool, and vomit at the source, and the makers say the bottle delivers up to 50 uses. Owners mention it works on wood, tile, walls, and carpet without leaving a film, and one notes it stopped a cat from re-marking the same spot immediately.

The recurring gripe, at 11 mentions, is the spray bottle leaking while in use. Most owners find the value strong, but a few report lingering odor on months-old stains and reseal the verdict on set-in messes.

A plant-based, pH-neutral formula that tackles grease and ink, not just pet messes.

This two-pack stands out because it’s not a urine-only product. The plant-based enzymes are billed as safely cleaning pet stains, food spills, grease, and even ink from carpets, rugs, upholstery, and drapery. It’s pH neutral, biodegradable, never tested on animals, and free of harsh chemicals and VOCs — a strong pick for households with kids crawling around.

Customers note it works wonders on low-pile, high-traffic stairs, pulling out four years of built-up dirt with minimal scrubbing. The natural lemon scent from essential oil is the second most-praised aspect after effectiveness, and one owner notes it cleans like diluted bleach without any staining. The method is simple: spray generously, let it soak for 5 minutes, then wipe with a sponge.

The catch is patience. Reviewers point out a tough stain may take a couple of applications before it fully lifts — one owner sums it up as coming “cleaner than anything else I’ve used,” just not always on the first pass.

The low-foam shampoo made for carpet extractors and wet-dry vacuums.

This is the one to grab when your carpet needs a whole-room reset, not just a spot treatment. Specially engineered for carpet extractors, rug shampooers, and wet-dry vacuums, the 32-fluid-ounce bottle penetrates deep into fibers to lift embedded dirt. The low-foaming formula leaves no sticky residue, which keeps carpets clean longer and prevents quick re-soiling.

The scent is the top praised aspect at 81 mentions, with owners describing it as clean, herbal, and not perfumy. One buyer who tried many enzyme cleaners before says this is the only one that worked on puppy accidents, noting that heavily set-in pee may need a few passes. Another notes a little goes a long way and that it smells citrus-like while staying gentle on pets and people.

The honest wrinkle is value: 14 owners flag it as not worth the price. The 32-ounce size runs out fast across a whole-home machine clean, and there’s no larger refill option — one owner explicitly wishes for a bigger bottle.

A bio-enzyme spray that reportedly saved a home sale by killing basement cat odor.

Effectiveness leads the praise here with 133 mentions, and owners specifically call out cat urine as the forte. The advanced bio-enzyme formula is designed to penetrate at the molecular level, dissolving urine, feces, vomit, and drool at the source. One property owner poured it directly on spots in a sold home’s basement, and once dry, the odor was gone.

The neutral scent is the second most-praised aspect at 124 mentions — no chemical perfumes masking the problem. The spray mists wide and covers a lot, and the bottle is solid with no leaks, per owners. It’s a simple shake, spray, and wait routine with no hands-and-knees scrubbing.

Stain removal is where opinions split. Some owners see stains vanish; others report the odor lingers after multiple tries over days. The sprayer quality also draws a mixed 21 mentions, and the formula is costlier per ounce than gallon jugs.

For sensitive noses, a plant-derived formula scented with mandarin orange and green tea.

The fragrance is the star here, with 98 owners praising the light herbal-lemon scent. One buyer with MCAS and chemical sensitivity reports no reaction at all — a rare distinction for a cleaning product. The plant-derived, enzyme-based formula targets dog urine on hardwood, carpet, and upholstery, leaving behind a fresh and clean scent.

Shoppers say it removes both new and old diarrhea stains from carpet, with old stains needing two to three applications. Regular use on dog bedding deters small dogs from urinating on blankets. The wide spray covers ground fast, and the bottle lasts a long time.

The mixed reviews center on residue and pet attraction. Some owners say it leaves floors sticky, while others report no filmy residue at all. A few dogs immediately re-mark over the spray, and the formula has no gallon refill, which one owner flags as a downside at this price point.

The bio-enzymatic spray that outperformed bleach in a black-light test, per owners.

This is the rare enzyme cleaner with a formal green light from the Carpet and Rug Institute, carrying their Seal of Approval for safe use on all carpets. It’s chlorine free, color safe, and has no hazardous propellants. In the review pages, owners describe it as outperforming both Nature’s Miracle and bleach on extensive cat spraying, verified under a black light.

You get the most buyer praise here: 15.3K effectiveness mentions and 7.2K on odor removal, far more than any other pick in this guide. It breaks down urine, feces, and vomit on carpets, floors, furniture, litter boxes, and even cars, and it stops cats from re-marking treated spots. The formula works with a Bissell machine for deep cleaning, so you can power it into the fibers.

The trade-off is the scent, which is mixed across 13.8K mentions. Owners describe it as a strong black-licorice or tea-tree smell that requires ventilation; one buyer wore a respiratory mask during use and noted a two-hour dry time. A few report the smell took days to fully air out.

A full 128-ounce gallon that resurrected a rug black with 11 years of dried pee.

If you’re facing years of neglect, this is the jug for the job. The unscented, enzyme-based formula works as both a spot cleaner and a full-area treatment. One owner describes a grandfather’s rug that was “almost black” with an intact male Shih Tzu’s 11 years of marking — this product brought it back. At 128 ounces, it matches the Nature’s Miracle jug for volume, though the formula here is unscented rather than fragrance-forward.

Buyers report it works on carpets, rugs, hardwood, and upholstery, and it supports puppy training by removing the scent markers that trigger repeat accidents. It’s an easy pour-on with reliable results — the strongest effectiveness angle at 49 mentions. One owner with two dachshunds uses it with and after pee pads for clean, fresh-smelling results.

The recurring gripe is the cap, which one owner calls “worthless,” and the scent is mixed: some owners note a strong initial smell that fades. The residue aspect is also split, with a few reporting it leaves worse stains on some surfaces, while others say carpets come out undamaged.
