If your carpet has a pet stain that keeps coming back after every cleaning, the problem is usually the residue left deep in the fibers, not the surface. A plant-based enzyme formula digests that residue instead of covering it up. Below are the nine natural carpet cleaners worth your money, sorted by what each one actually does best.
I’m Min — the founder and writer behind Gadgets Feed. 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.
You will see which formulas need a deep cleaner machine and which work as a simple spray-and-soak, so you do not buy the wrong bottle. Every pick here is plant-based, and each one has a clear job it handles better than the rest, which makes narrowing down your all natural carpet cleaner far less of a guessing game.
Our Picks at a Glance
How To Choose The Best All Natural Carpet Cleaner
Most people buy a natural carpet cleaner, spray it on, scrub, and wonder why the smell returns a week later. The fix starts with picking a formula built to break the stain down, not just wet the surface.
Machine Formula vs. Spray Bottle
A machine formula is designed to be poured into a portable carpet deep cleaner, where it gets pushed into the fibers under pressure. A spray bottle is meant to be applied by hand, left to soak, then wiped or blotted. Buying a machine-only bottle and using it as a spray wastes product and often underperforms. Check the label wording before you commit.
What “Enzyme” Really Means On The Label
Enzymes are proteins that break organic material — urine, vomit, food, blood — into smaller pieces. A live-culture formula keeps working after you walk away, so it can beat a detergent that only lifts what it touches. Plant-based enzymes do the same job without the synthetic detergent base.
Fragrance, Dyes, and Who Is Crawling On The Rug
Some formulas add a natural lemon or citrus scent from essential oils. Others are fragrance-free. If a baby or a pet spends time on that carpet, a fragrance-free or low-scent option is the safer bet for daily use. None of these products should be judged on smell alone — the cleaning result is what counts.
Match The Bottle To The Mess
Fresh pet accidents, set-in wine stains, and general traffic dirt each respond differently. A fast-acting spot remover handles a fresh spill. A live-culture formula that stays active for hours suits old, soaked-in odors. Match the formula to the mess you actually have.

In‑Depth Reviews
1. Bissell Simply Spot & Stain Portable Carpet Cleaner Formula, 32 oz, 3368
Our pick — 4.5+★ from 850+ verified ratings; the strongest balance of quality and price.
The bottle built for your little spot cleaner — and the one owners keep coming back to.
Here is the practical thing to know first: this is a machine formula, not a spray bottle. You pour it into a portable carpet deep cleaner, and the machine pushes it into the fibers to loosen embedded dirt. If you own one of those small area cleaners, this is the formula it was designed for. If you do not own one, buy a spray bottle instead.
The formula itself is plant-based, made with biodegradable detergents, and contains no heavy metals, phosphates, or dyes. It handles the tough pet messes — urine, vomit, blood, and tracked-in dirt — on area rugs, carpet, and upholstery. A little goes a long way, which is why one bottle stretches across many cleanings. The pleasant fragrance is the part that wins people over most, and it stays light rather than chemical-heavy. It is also formulated to be gentler than typical cleaners, so it is not as harsh on the fibers or the room.
Where it falls short is scope. It cannot be sprayed directly onto a stain and left to work — it needs the machine to do its job. A 32 oz bottle also sits at the small end next to the gallon-size picks further down this list. For a household with a portable cleaner and regular pet accidents, though, this is the easiest call on the page.
What Makes It The Default Pick
- Plant-based with biodegradable detergents and no phosphates, dyes, or heavy metals
- Gentler on fibers than many standard cleaners, according to buyer feedback
- Light, pleasant scent that does not linger like a chemical cleaner
- Handles urine, vomit, blood, and tracked-in dirt on rugs and upholstery
Where It Stops Short
- Requires a portable carpet deep cleaner — it is not a stand-alone spray
- 32 oz is a smaller bottle than the gallon options here
Buy it if: you already own a portable carpet deep cleaner and want a plant-based formula that will not punish the fibers.
Pass if: you need a bottle you can spray on a spot and walk away from.
2. Biokleen Bac-Out Pet Stain Remover, 32 Ounce
A live-culture formula that keeps eating the stain long after you stop spraying.
What separates Bac-Out from a detergent cleaner is the live enzyme cultures. They break down and absorb organic material instead of just lifting it off the surface. That is why it can work on drool, vomit, blood, poop, and urine — the same biology that makes those stains smell is what the enzymes feed on.
The surface list is where this bottle earns its place. Carpets, couches, collars, kennels, pillows, bedding, even a mattress are all on the label, and it leaves a fresh natural scent that is made to be around dogs and cats. It is plant-based with no artificial fragrances or dyes, and it contains no phosphates, chlorine, ammonia, or brighteners. Made in the USA, never tested on animals, with biodegradable ingredients. Set it beside the Bissell above and the difference is scope: the Bissell needs a machine, while this one goes anywhere a spray can reach.
The trade-off is scent: Bac-Out’s natural smell is mild but present. Bac-Out’s natural smell is mild but present, so a household that wants zero fragrance should look at the Earthworm bottle below. For multi-surface pet cleanup, though, few bottles cover this much ground.
Surface range is the headline: a single bottle that handles carpets, couches, kennels, bedding, and laundry means one product instead of three.
The catch worth knowing: the natural scent is noticeable, and the bottle is 32 oz — the larger refill format sits further down this list if volume matters.
Reach for it when: pet messes land on more than just the carpet — the couch, the kennel, the bedding.
Look elsewhere if: you need a completely unscented formula for a sensitive room.
3. naturally it’s clean Carpet Stains & Odors Cleaner, 24oz Spray x 2 Pack
Two spray bottles of enzyme cleaner that dissolve stains instead of masking them.
The method on the label is refreshingly plain: shake, spray generously, soak for 5 minutes, then wipe or scrub with a sponge. That is the whole routine. The enzymes are plant-derived and the formula is pH neutral, which means it does not lean acidic or alkaline against your carpet fibers. It is biodegradable, never tested on animals, contains no VOC and no hazardous propellants, and the lemon scent comes from essential oil rather than a synthetic fragrance.
People reach for this one because it genuinely gets rid of stains without leaving a strong chemical smell behind. The safety side matters too — it is non-toxic, and one buyer felt comfortable letting a baby crawl on the treated carpet. It handles pet messes, food, wine, grease, and ink across carpet, rugs, upholstery, and drapery without discoloring the material. For the price of one bottle you get two, which makes it the sensible pick for a household that cleans often.
The five-minute soak is the part that cannot be skipped. Spray-and-wipe in ten seconds will not give the enzymes time to work. Give it the full soak and the results hold up; rush it and you will think the bottle failed. Also worth noting: two 24 oz bottles total less liquid than a single 32 oz bottle plus a refill, so heavy users may burn through this pair quickly.
The right fit for: anyone who wants a simple spray-soak-wipe routine and a non-toxic formula safe around a crawling baby.
Not the one for: impatient cleaners who will not leave it soaking for the full five minutes.
4. Eco Strong Cat Stain And Odor Remover, Citrus Scent, 32 oz Spray
Built for the one mess cat owners know best — urine, and the smell that outlives it.
Cat urine is a different animal from a spilled glass of wine. It soaks down and keeps releasing odor, which is why a surface spray often fails. Eco Strong is a bio-enzymatic formula that breaks down and consumes the stain-causing residue rather than covering it. The label claims it eliminates the odor rather than masking it. There is also a trick on the label worth stealing — after you scoop the litter box, spray it in the air above the box to knock down lingering smells.
The bottle goes beyond carpets. It works on floors, fabrics, bedding, and tile, and it handles urine, vomit, feces, and blood from either pets or people. If a cat has been peeing on bedding, you can wash with it and the odor goes. Compared with the Bissell machine formula above, this one does its work as a straight spray, no equipment required. It is made in the USA and the maker states it contains no toxic chemicals.
The honest note is on cost per ounce: some buyers feel the price is steep for the volume, and the maker’s own listing changed its label look without changing the formula. The cat-urine job is the one it is built for, and it does that job well. If general traffic dirt is your main problem rather than a specific pet spot, a cheaper multi-surface pick below will cover you.
The cat-urine angle: the formula is designed around the one stain that keeps stinking, and it works on bedding and litter box zones as well as carpet.
Budget caution: buyers who focus on value sometimes balk at the cost per ounce, so weigh it against how many bottles you will actually go through.
Made for: cat owners fighting a urine smell that keeps returning to the same spot.
Think twice if: your stains are general food and dirt spills rather than concentrated pet accidents.
5. Earthworm Carpet & Upholstery Cleaner Spot & Stain Remover, 22 oz
No scent, no harsh residue, and enough enzyme power to lift wine and nail polish.
If fragrance is the reason you keep hesitating, this is the bottle to start with. Earthworm is fragrance-free, which also means it leaves no perfume fighting with the smell you are trying to kill. The enzyme process is bio-enzymatic, and it is one of the few formulas here that lists nail polish alongside wine and food stains on its label. The maker says the formula is environmentally responsible and safer for use around kids, pets, and family, and it carries approval from the Carpet & Rug Institute.
The surface list runs wider than most people expect. Carpet, curtains, pillowcases, mattresses, and most colorfast materials are all fair game, and the result is gentle on surfaces rather than harsh. It also covers urine and vomit with no harsh chemical residue left behind. Compare it with the Eco Strong, which is the 32 oz bottle built for cat urine — Earthworm trades volume for a fragrance-free formula.
The trade-off is scent preference running the other way: if you like the smell of a lemon or citrus cleaner as confirmation that it worked, this will feel plain. Some buyers also say the price feels high for 22 oz. Neither is a defect — they are simply the fit.
What Owners Rely On
- Fragrance-free — no perfume competing with the odor you want gone
- Handles wine, food stains, and nail polish, not just pet accidents
- Approved by the Carpet & Rug Institute
- Safe for carpet, curtains, pillowcases, and mattresses
What To Weigh
- 22 oz is the smallest bottle on this list
- Some buyers find the cost high for the volume
Choose this one for: a fragrance-free formula that also handles nail polish and wine on curtains and mattresses.
Keep looking if: you want a big bottle and a scented confirmation that the enzymes did their job.
6. Only Natural Pet Advanced Stain & Odor Remover Cat Urine Cleaner, 32 fl oz
A 32-ounce enzyme spray with a neutralizer built into the scent, not on top of it.
The simple version: enzyme-powered, 32 fl oz, made for tough dog stains and odors from urine, and it leaves a fresh clean scent behind. That is a formula built around the mess a dog actually makes, not a generic all-purpose cleaner repackaged with a pet label.
Where this bottle stands out is the cleaning result on real carpet. Buyers report it works well on beige carpet, which is the shade that shows every set-in mark. The scent does the quieter job — it neutralizes odor instead of covering it, and the formula is described as not chemical or toxic, which matters in a house with pets. Pair it mentally with the Eco Strong above: both are 32 oz bio-enzyme sprays, but Earthworm’s fragrance-free approach and this fresh-scent angle put them in different rooms.
The one thing to know before you buy is the limit on older stains. It removes stains well, but set-in marks that have been there a long time may not come fully out. That is not a flaw in the formula so much as a fact of aged carpet — treat it as a fresh-mess tool and it will not disappoint.
What you notice first: the scent neutralizes rather than masks, and it cleans visibly on light-colored carpet.
Worth knowing: old, set-in stains may not fully lift — it is strongest on fresh accidents.
Ideal for: dog owners with light carpet and fresh urine stains to clean.
Skip if: your stains have been setting in for months and you expect a full reset.
7. Rocco & Roxie Enzyme Stain & Odor Eliminator, 32 Fl Oz
The enzyme eliminator with the deepest review history on this list — and the one built to stop repeat accidents.
Most cleaners stop at removing the stain. Rocco & Roxie adds a step that actually changes pet behavior: it makes the odor disappear so pets are less drawn back to the same spot. Its enzymes activate on contact, feeding on ammonia crystals and organic matter deep in the fibers until they are gone. If your dog or cat keeps returning to one corner of the carpet, that mechanism is the reason to consider this bottle.
It is certified gentle and safe, chlorine-free, and color-safe, with no hazardous propellants or residue, and it carries the CRI Seal of Approval for all carpets. The stain list covers pet urine and feces, vomit, and other organic spills, and one reviewer noted their dog simply stopped peeing in the house after using it.
The trade-off is cost. Some buyers feel it is not worth the price per ounce, and at 32 fl oz you will be buying it again if you use it often. A rare set of buyers also says repeat purchases feel expensive.
Get this if: your pet keeps hitting the same spot and you want a formula that removes the odor drawing them back.
Don’t if: you want the cheapest bottle per ounce and your stains are one-off spills.
8. Bastion Probiotic Enzyme Cleaner, One Gallon
A whole gallon of live cultures that keep working for hours after you walk away.
Here is the number that matters on this bottle: the maker states its probiotics remain active for up to 80 hrs, continuing to work against new soils and odors as they emerge. No other bottle here claims an active window that long. The formula works with two stages — enzymes break complex waste into smaller pieces, then the probiotics consume them and convert the result into carbon dioxide and water. Nothing stays behind to build up.
The no-rinse design suits people who want to spray and move on. There is no measuring, no mixing, no diluting — just saturate the area and let it work. It will not leave haziness, film, streaks, stickiness, or residue behind, and the maker says it contains neither bleach nor chlorine. The gallon size and multi-surface coverage push it into whole-home territory: carpets, hard floors, laundry, drains, grease traps, toilets, and septic tanks are all on the label. Compared with the 32 oz Rocco & Roxie above, this is a bulk bottle that covers more of the house for someone who buys one product rather than seven.
The caveat is real. Odor removal gets mixed results from buyers — some say it eliminates odors, others say it does not. The 8.55 pound jug is also a heavy thing to move around compared with a 32 oz spray bottle, and a handful of owners mention leakage in transit. It earns its place for whole-home use, not for a single spot treatment.
The standout spec: up to 80 hrs of active culture work on a single application, with no rinse and no residue left behind.
The honest limit: odor results are mixed, and the weight means this is a shelf product rather than a carry-around bottle.
This one is for: homeowners who want one bulk jug that also handles drains, septic, and hard floors.
Second-guess it if: you need a lightweight bottle you can keep by the sofa for quick spot sprays.
9. Biokleen Bac-Out Stain Remover for Carpet, Clothes, 32 Ounce and Gallon Refill
One spray bottle, one gallon refill — the same live enzyme formula, sized for people who use it constantly.
This is the practical version of Bac-Out. The single 32 oz bottle earlier on this list is the entry point; this set pairs a 32 oz spray with a gallon refill so you pour a top-up rather than buying a new bottle every time. The formula is unchanged: live enzyme cultures that break down and absorb organic material, ready to use with no diluting.
The plant-based base has no artificial fragrances or dyes, no phosphates, chlorine, ammonia, or brighteners, and it carries no added fragrance. That no-added-fragrance label matters for households that do not want any added smell. The list of jobs covers pet accidents, wine spills on carpets and couches, cloth diapers and pails, laundry, disposals, and garbage cans. One buyer mentioned it also cleaned up oil on a driveway. The unobtrusive lime essence fragrance is the natural scent of the ingredients at work, not an added perfume. Everything is biodegradable, never tested on animals, and made in the USA.
The thing to plan for is the refill routine. The gallon jug makes this a two-bottle system in the home — a storage jug plus the spray bottle you fill from it. For occasional use that is more bottle than you need. For anyone with kids in diapers or pets in every room, though, the refill approach is the one that prevents running dry in the middle of a mess.
Why The Refill Set Works
- 32 oz spray plus a gallon refill — no reordering during a cleanup
- Live enzyme cultures that break down organic material
- No added fragrance, plant-based, with no phosphates, chlorine, or ammonia
- Covers carpets, couches, laundry, diapers, disposals, and garbage cans
What You Should Plan For
- Two-bottle system to store — a jug plus a spray
- More volume than a single-spot household will need
Stock it if: pets or kids mean frequent cleaning and you want the refill bottle waiting on the shelf.
Not for: a single occasional spill where one 32 oz bottle is plenty.
Understanding the Specs
Bio-Enzymatic vs. Probiotic Formulas
Enzymes are proteins that break large organic molecules into smaller pieces. Probiotic formulas go one step further: the live cultures actually consume those smaller pieces as food. That is why a probiotic bottle can keep working for hours after you spray, while a plain detergent formula stops the moment you wipe it up. Both types are still enzyme cleaners — the difference is whether the culture stays alive on the carpet.
Capacity and Bottle Format
Capacity tells you how many runs you get between purchases. A 32 fl oz spray covers several spot cleanings; a one-gallon jug covers months of whole-home use. The format matters just as much as the volume. Spray bottles are for hand application and always need a soak-and-blot. Machine formulas are only for portable deep cleaners and do nothing useful if sprayed by hand. Check the word “portable” on the label before you assume a formula is a stand-alone spray.
Fragrance and Sensitivity
Plant-based cleaners can still carry a scent — the source is often essential oil or the natural smell of the enzymes themselves. Fragrance-free options suit rooms where a baby crawls or a pet sleeps. Scented options are fine as long as the scent is part of the clean, not a mask over an odor that is still there.
Surface Compatibility and Certification
“Carpet only” is rare among natural formulas. Most handle upholstery and bedding, and some list curtains and mattresses. Two certifications matter: the CRI Seal of Approval (Carpet & Rug Institute) and CRI approval more broadly, both a signal that the formula has been assessed for use on carpeting. If a bottle lists either, its claimed safety on carpet carries more weight.

Final Thoughts: The Verdict
For most households, the all natural carpet cleaner that earns its place first is the Bissell Simply Spot & Stain — it is plant-based, gentle on fibers, and built to work with the portable carpet machine many people already own. If your messes land on couches, kennels, and bedding as often as on carpet, the Biokleen Bac-Out Pet Stain Remover is the more flexible bottle. And for a cat owner fighting a returning urine smell with no machine at hand, the Eco Strong Cat Stain And Odor Remover is the one to reach for.
The one nudge worth making: the Rocco & Roxie formula has the biggest history on this page and the only one that directly addresses repeat accidents. If a returning pet spot has been beating you, that is where your money is best spent first.
