When a pet or a child empties their stomach on your carpet, the clock starts ticking. The right enzyme-based spray digests the organic matter at the source, so the stain lifts and the odor stays gone even when the carpet warms up. This guide ranks enzyme cleaners that digest vomit, urine, and feces instead of merely masking the smell.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The best cleaner for vomit needs enzymes that keep working long after you spray, plus a formula gentle enough for daily use around pets and kids.
Our Picks at a Glance
How To Choose The Best Cleaner for Vomit
Vomit combines stomach acid, half-digested food, and enzymes that stain fabric and embed odor into carpet fibers. A fragrance-only spray will fail when humidity returns the odor. Choose a biological cleaner with live cultures that consume the organic waste.
Look for live enzymes, not just perfume
Enzyme formulas break down proteins and starches into carbon dioxide and water, eliminating the stain rather than masking it. Check that the label names enzymes or probiotics, and avoid anything that relies entirely on fragrance to sell the “clean.”
Match saturation time to your patience
The most effective sprays require a 10- to 30-minute dwell time for the cultures to digest the mess. If you spray and wipe immediately, prioritize a fast-acting formula over a deep-digesting one.
Consider the bottle size for your household
A single 22-ounce bottle handles the occasional accident, while a full gallon suits multi-pet homes or professional use. Bigger bottles cost less per ounce, but you have to store them somewhere accessible for those 2 a.m. emergencies.
Check the safety claims before spraying near kids
Many formulas are free of bleach, chlorine, phosphates, and artificial fragrance, which matters when you are cleaning a nursery or a dog bed your puppy sleeps on. Look for plant-based or biodegradable labels if you want to avoid harsh residues.

In‑Depth Reviews
1. Bissell Woolite Free & Clear Pet Stain & Odor Remover (2-Pack)
Our pick — over 4.5★ from 800+ verified ratings; the strongest balance of quality and price.
The fragrance-free workhorse that makes puppy and senior-dog accidents vanish without a single scent masking them
Households with multiple dogs — especially older ones with frequent accidents — reach for this one because it kills the urine smell rather than covering it. The 22-ounce bottles are packed two to a purchase, but you only get one sprayer; you unscrew it from the first bottle and reuse it on the second, a deliberate plastic-saving choice.
What wins people over is the stain-lifting power on red wine, blood, spaghetti sauce, grape juice, and vomit, all handled with the same formula. It is free from dyes, artificial fragrance, phosphates, and optical brighteners, which is why chemically sensitive households keep it stocked. The label also skips bleach and chlorine, so it stays gentle on your senses while you scrub.
Buyers report that a prompt spray and minimal scrubbing lifts even red wine from a white rug, and that heavy cat-pee situations sometimes need a high-enzyme pre-treatment first. One note: it is still a chemical cleaner, so the review pages recommend washing your hands after use and keeping paws off the carpet until it dries.
The Everyday Workhorse
- Handles vomit, urine, blood, and food stains in one formula
- No dyes, fragrance, phosphates, or brighteners
- Two 22-ounce bottles per pack
Read The Fine Print
- Only one sprayer included for two bottles
- Heavy soiling may need an enzyme pre-treatment first
Grab it for: fragrance-free cleaning of pet and food stains on carpets and fabric.
Think twice if: you want a built-in sprayer on every bottle — you will be moving one nozzle around.
2. Simple Solution Extreme Stain & Odor Remover
The budget-friendly enzymatic spray that digs into both fresh and years-old pet messes
For the cost of a mid-range lunch, this 32-ounce bottle brings a formula the brand claims is three times stronger than its regular version, built specifically to break down urine, feces, and vomit. The patented 3-in-1 nozzle switches between mist, foam, and stream, so you can foam a carpet spot or stream into a crack.
The stain-removal reputation here is strong enough that the review pages report it saved thousands in carpet replacement costs after a basement apartment had severe dog-urine odor. It is pet-safe and family-friendly, works on carpets, upholstery, bedding, fabric toys, clothing, and other water-safe surfaces, and you use only a small amount per spot.
The honest catch is the spray nozzle. The chemical itself earns top marks for cat vomit and feces with no stain or odor left behind, but the nozzle leaks when tilted — plenty of owners simply swap in their own spray bottle and move on. The scent is strong while wet but fades once dry.
Why it earns its spot: three times the enzyme power of the regular formula at a price that makes it easy to keep two bottles in the house.
The trade-off: expect to replace the flimsy nozzle with a spare trigger spray.
3. Woolite Advantage INSTAclean Pet Stain Remover (2-Pack)
The 30-second stain destroyer that cat owners keep within arm’s reach for hairball season
This is the one the review pages describe as the go-to for cat hairballs and “ate too fast” carpet landings, lifting roughly 99% of fresh stains with minimal effort. The Pet Oxy Stain Destroyers formula works in 30 seconds, which matters when you are standing over a fresh mess at midnight. It also carries 25% more odor-block technology than the standard version, leaving a long-lasting fresh scent behind.
Unlike the Fragrance-Free Bissell above, this one is unashamedly scented, and owners mention it tackles urine, feces, vomit, tracked-in dirt, and blood across carpet, rugs, upholstery, car interiors, clothing, tile, laminate, and vinyl. Overnight stains need extra blotting and rubbing, but fresh ones lift cleanly with a spray and a wet rag.
The recurring praise centers on speed: spray, follow with a wet rag, and the stain is gone without reappearing. One caveat from the label is that it is biodegradable, so it is a greener pick than many enzyme sprays on the shelf.
Split-Second Rescue
- Stains lift in 30 seconds flat
- Two bottles so you always have a backup
- Works on soft and hard surfaces alike
Know The Limits
- Overnight stains demand extra blotting and rubbing
- Fresh scent may not suit fragrance-free households
Reach for it when: you need a stain gone immediately and you value speed over unscented formulas.
Look elsewhere if: you prefer zero fragrance in your cleaning routine.
4. Eco Strong Cat Stain And Odor Remover
The citrus-scented bio-enzymatic spray that convinced a professional cleaner it is the only tool that works
When a working cleaner says this is “the only thing that helps pet odor in my bag of tricks,” you pay attention. The bio-enzymatic formula breaks down and consumes odor-causing residue rather than masking it, and the light citrus scent dissipates quickly instead of lingering like a chemical fog. It is made in the USA with no toxic chemicals in the recipe.
The real fans are multi-cat households dealing with unneutered male urine in carpet and plastic litter boxes. The technique involves spraying, waiting 15 to 30 minutes, and letting the enzyme work — one owner reported soaking a plastic litter box, waiting half an hour, then washing with Dawn to eliminate the odor almost entirely. It also works in the wash for bedding and on vomit, feces, and blood.
You get professional-grade odor digestion (enzymes that eat the smell-causing molecules) plus a scent that actually refreshes, not just masks. The strong cleaning scent means you will want to air out the room while you spray, but it fades quickly. The brand says this breaks down odors permanently rather than just covering them up.
What wins people over: litter-box odors that stay gone between scoopings, with a pleasant citrus finish.
Worth knowing: the strongest results need 15 to 30 minutes of sit time before you blot.
5. Hepper Bio-Enzyme Pet Stain & Odor Eliminator
The no-scrub enzymatic spray that erases cat urine smells without leaning on chemical perfume
The pitch here is simple: shake, spray, and wait — no scrubbing, no getting down on your hands and knees. The advanced enzymatic formula penetrates stains at the molecular level to dissolve urine, feces, vomit, and drool across carpets, floors, furniture, and fabrics. Rather than relying on chemical fragrances, it eradicates the smell itself and leaves a neutral scent behind.
Customers note cat-urine success stories, including a mattress rescued after being peed on, and one owner who found this to be the first spray of three that actually eliminated the smell on carpet, vinyl, and plastic. The neutral, natural odor is a deliberate design choice for people who cannot handle strong artificial scents.
The trade-off shows up in the hardware. The sprayer quality draws criticism — some nozzles leak on fingers mid-use, and one stopped working while the bottle was still half full. It is a 32-ounce value bottle, but you may want a spare trigger spray handy.
The verdict: genuinely effective on stubborn urine with a scent profile that disappears rather than announces itself.
The caveat: the included sprayer is the weakest link, so budget for a replacement nozzle.
6. Rocco & Roxie Enzyme Stain & Odor Eliminator
The certified-safe enzyme cleaner that tackled a cat’s mattress accident overnight
This professional-strength spray comes with a Seal of Approval from the Carpet and Rug Institute, meaning it is certified safe for all carpets — a meaningful credential when you are dousing your living room rug. It is chlorine-free, color-safe, and free of hazardous propellants, so it works around pets and children without leaving residue behind.
The enzyme formula handles stinky yellow urine, feces, vomit, and other organic spills on carpets, floors, furniture, clothing, litter boxes, kennels, and carriers. Reviewers point out it eliminates cat spray odor and stops re-marking behavior, and that it works on bedding and mattresses even hours after the accident. Use it with a carpet machine for the best deep-clean results.
The honest trade-off is the fragrance. The scent is strong — one owner called it overwhelming and suggested airing the room out after spraying. It fades with airing, but if you are fragrance-sensitive, you will notice it during use.
The Heavy Lifter
- Carries the CRI Seal of Approval for carpet safety
- Removes fresh and old stains, deters re-marking
- Chlorine-free and safe around kids and pets
Plan For The Scent
- Fragrance is powerful right after spraying
- Premium price per bottle compared to value picks
Choose it for: deep-set organic odors on carpet and bedding where certification matters.
skip it if: you cannot tolerate a strong scent even for a short window.
7. Biokleen Bac-Out Pet Urine Odor Eliminator (2-Pack)
The plant-based enzyme duo that senior-dog owners swear by for accidents that keep happening
When your senior dog starts having accidents, you need something gentle enough for daily use and strong enough to actually work. This bio-enzymatic cleaner uses live enzyme cultures to break down drool, vomit, blood, poop, and urine across carpets, couches, collars, kennels, pillows, bedding, and even mattresses. It is plant-based with no artificial fragrances or dyes, and it never contains phosphates, chlorine, ammonia, or brighteners.
The two-bottle bundle includes a washable, reusable microfiber towel, which is handy for blotting fresh messes. Owners praise the pleasant, natural scent that does not smell like a chemical factory, and note it works especially well as a laundry pre-treatment for stinky clothes and sneakers. The method matters: saturate fully, wait about 10 minutes, blot, and let it air dry.
The one recurring issue is the bundled towel — several buyers reported it does not arrive with the package. The spray bottle itself also gets described as weak for heavy stain work, though the formula shines for odor and laundry duty.
Why it stands out: a genuinely plant-based formula that still handles the toughest organic odors.
Set expectations: the microfiber towel may not arrive, and the sprayer is better for odors than heavy staining.
8. ODORx Un-Duz-It Unleashed Pet Stain Remover
The gallon-sized professional formula a restoration pro calls the best for urine odor elimination
This is the cleaner the cleaning industry itself reaches for — one restoration professional flatly calls it the best product for urine odor elimination. The one-gallon bottle is built for heavy use, and the brand says professionals prefer it for removing tough pet stains and odors from fabrics, wood, laminates, and hard porous surfaces like concrete. It works on virtually any water-cleanable surface.
The saturation method matters here: pour full strength, let it sit for an hour, extract with a wet vac, rinse, and then carpet-clean. Owners who followed the directions report eliminating cat-pee smell that vinegar and baking soda could not touch, and they note the 128-ounce bottle lasts a long time because you pre-mix an applicator bottle as needed.
The honest limitation is that it removes odor brilliantly but not stains. Reviewers are clear that you need a separate product for discoloration and this one purely for the smell — which it does permanently. The fresh scent is pleasant but lingers for a few hours before fading.
The Restoration Standard
- Gallon size delivers serious value for heavy use
- Eliminates urine odor permanently on wood and concrete
- Professionals’ preferred formula
Know The Split
- Removes odor but not stains — plan a second product
- Best results require extraction, not just spraying
Best for: homeowners battling deep urine smells in subfloor, concrete, or wood who can follow a multi-step extraction routine.
Not for: quick spot cleanups where you also need the stain gone in one pass.
9. Bastion Probiotic Enzyme Cleaner (1 Gallon)
The probiotic gallon whose live cultures keep eating new spills for up to 80 hours after you spray
What makes this different is the biology: live probiotic cultures stay active for up to 80 hours, so they keep working against new soils and odors as they emerge rather than quitting after one pass. The enzyme-activated formula breaks down complex compounds — urine, grease, food stains, wine, coffee, blood, and vomit — into carbon dioxide and water, which is why it leaves no film or residue.
The no-rinse, ready-to-use formula is commercial-grade and needs no measuring or diluting. It works across hard surfaces, floors, carpets, fabric, laundry, drains, grease traps, toilets, and septic tanks, and it is non-toxic and hypoallergenic with no bleach or chlorine. The gallon size suits households that want one bottle for every kind of organic mess.
The honest feedback is more mixed on texture than on effectiveness. Shoppers say it gets sudsy when used with a mop and recommend rinsing rather than just wiping, which can take a few buckets of water. One owner found it no better than dishwashing detergent, though the majority report strong odor elimination on cat and bunny urine that had been sitting for a while.
Why it stands apart: no other pick on this list keeps working for days after the initial spray.
The practical note: expect suds when you mop large areas, so plan extra rinsing.
Understanding the Specs
Enzyme vs. Probiotic Formulas
Enzyme cleaners break down organic waste into smaller particles, which is what lifts stains from carpet fibers. Probiotic cleaners go one step further: live cultures consume those particles and turn them into carbon dioxide and water, which is why they keep working over time rather than stopping at the first pass. For vomit, either approach works, but probiotics offer longer-lasting protection against recurring odors.
Bottle Size and Cost Per Use
A 22-ounce spray handles occasional accidents and fits easily under a sink, while a full gallon suits multi-pet homes or households that clean large carpeted areas regularly. Larger bottles cost more upfront but last far longer per ounce. The trade-off is storage — a gallon jug needs shelf space near the mess, not buried in a garage.
Saturation Time
Most enzyme cleaners ask you to let the formula sit for 10 to 30 minutes so the live cultures can digest the organic matter. Fast-acting formulas claim results in as little as 30 seconds, but deeper or older stains always benefit from longer dwell time. If you are the impatient type, choose a cleaner marketed for speed; if you want permanent odor removal, patience pays off.
Nozzle Types and Spray Patterns
Some cleaners ship with a simple trigger spray, while others include a 3-in-1 nozzle that switches between mist, foam, and stream. A mist works for surface stains, foam clings to vertical upholstery, and a stream reaches into cracks and crevices. The nozzle is the most common point of failure across brands, so consider keeping a spare trigger spray on hand regardless of which cleaner you buy.
