Standard carpet cleaners often leave behind a chemical film that attracts dirt faster than it cleans, or they rely on synthetic fragrances to simply mask odors rather than eliminate them. For anyone dealing with persistent pet stains, set-in food spills, or the need for a non-toxic home environment, the switch to a plant-based formula is not just a preference—it’s a practical necessity.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. My research process involves digging into formulation data, comparing enzyme activity claims against real-world customer feedback, and analyzing how each product’s ingredient list holds up against the promise of being all-natural.
After evaluating dozens of options across multiple price points, I’ve narrowed the field to five standout formulas. This guide breaks down the key differences in composition, application, and effectiveness to help you find the best all natural carpet cleaner for your specific situation.
How To Choose The Best All Natural Carpet Cleaner
Not all “natural” labels are created equal. Some products hide petroleum-based surfactants behind vague marketing terms, while others deliver genuine plant-powered enzyme activity. Here are the three factors that matter most when choosing a cleaner for your carpets.
Enzyme Activity vs. Surfactant Lift
Enzyme-based cleaners use biological catalysts to break down organic matter—urine, vomit, food, mud—into simple gases and water. This removes both the stain and the odor at a molecular level. Surfactant-based cleaners rely on detergents to lift dirt, but they often leave a sticky residue that attracts new soil. For deep-set organic stains, always prioritize a cleaner with active enzymes over one with only plant-based soap.
Residue and pH Balance
A pH-neutral formula (around pH 7) is critical for synthetic carpets and wool blends. Alkaline cleaners can discolor wool fibers and leave a brittle residue that dulls the pile. Plant-based enzyme cleaners are typically pH-balanced, rinsing out cleanly without the need for a separate extraction step. If your carpet is labeled “Code S” (synthetic) or “Code W” (wool), check that the product explicitly states it will not cause yellowing or alkalinity damage.
Fragrance Source
“Natural scent” can come from either steam-distilled essential oils or from added “natural aroma” compounds that are chemically identical to synthetic fragrances. Essential oils like lemon, orange, or lemongrass provide legitimate antimicrobial benefits and a clean smell that fades naturally. Masking-fragrance blends, even if derived from natural sources, can still trigger sensitivities in pets and people. For the purest all natural option, choose an unscented formula or one that explicitly lists the essential oil used.

In‑Depth Reviews
1. naturally it’s clean Carpet Stains & Odors Cleaner (2 Pack)
This two-pack from naturally it’s clean is the closest thing to a true “set it and forget it” enzyme cleaner. Powered by pure plant-derived enzymes rather than synthetic detergents, it tackles organic stains—vomit, wine, pet urine—by breaking them down at a biological level. The label confirms it is pH neutral, biodegradable, and free of VOCs, hazardous propellants, and artificial fragrances. The natural lemon scent comes exclusively from essential oils, so there is no synthetic masking layer.
Real-world feedback is strong across the board. Owners report that a generous soak of 5 minutes is usually enough to lift dirt from low-pile, high-traffic carpets with minimal scrubbing. Older, set-in stains may require a second application, but users consistently note that the formula does not discolor fibers or leave behind a sticky residue. The 2-pack format is practical for households that clean multiple rooms or need to keep one bottle upstairs and one downstairs.
The main consideration here is patience. Because enzymes need time to work, rushing the process with an immediate blot-and-scrub routine reduces effectiveness. For spots that have been ground into the carpet for weeks, a longer dwell time—up to 15 minutes—delivers noticeably better results. For a completely non-toxic, pet-safe cleaner that actually removes odors rather than covering them, this is the most balanced option available.
What works
- True enzyme activity eliminates odors instead of masking them
- pH neutral and non-toxic—safe for wool and synthetic carpets
- Pleasant, non-artificial lemon scent from essential oils
- 2-pack provides excellent value for multi-room use
What doesn’t
- Requires 5+ minutes of dwell time for full enzyme activation
- Very old or deeply set stains may need a second application
2. BugMD Enzyme Cleaner for Dog & Cat Urine
BugMD takes a deliberately different approach: no scent at all. This is a fragrance-free, unscented enzyme cleaner designed specifically for owners of sensitive pets or people who react to any kind of fragrance—even essential oils. The professional-strength formula targets ammonia crystals in dried urine, breaking them down so thoroughly that the odor does not return after the carpet dries. It is ready to use straight from the bottle with no mixing or dilution required.
Customer reports highlight its effectiveness on older, dried-in stains that other cleaners failed to touch. One reviewer described pouring it on a set-in stain, letting it sit for one hour, blotting with dry towels, and finding both the stain and odor completely gone. Another user successfully removed cat urine smell from shoes after trying multiple other products. The multi-surface versatility extends to hardwood, upholstery, and kennels, though some users noted that carpet stain removal worked better than fabric stain removal.
The unscented nature is both its biggest strength and its only real limitation. While it eliminates odors at the source, there is no fresh-smelling after-scent to signal that the carpet has been cleaned. For households that want absolute purity with zero perfuming, this is the best option. For those who prefer a light botanical scent after cleaning, one of the citrus-based alternatives may feel more satisfying.
What works
- Completely unscented—no perfumes or essential oils
- Professional-strength enzymes eliminate odors permanently
- Safe for use on multiple surfaces including hardwood and upholstery
- Ready to use, no mixing required
What doesn’t
- No fresh scent after cleaning—carpet simply smells neutral
- Some users found it less effective on fabric stains than carpet stains
3. Capture Carpet & Rug Dry Cleaner Powder
Capture breaks the mold by offering a dry cleaning solution rather than a liquid spray. This powder acts like microscopic sponges that absorb dirt and odors from deep within carpet fibers without adding any moisture. The “no wicking” advantage is significant: because water is not introduced, stains that have already wicked up from the backing will not reappear after the carpet dries. The 1-pound pail covers up to 100 square feet, making it an economical option for whole-room refresh cycles.
User feedback emphasizes its value for large, light-colored carpets where periodic deep cleaning is needed without wet extraction. One long-term user reported successfully removing dried red ink from beige plush carpet, while another used it to clean a 10-year-old wool rug without any fiber damage. The application process is straightforward—sprinkle, wait, vacuum—but the included brush is widely considered too small for practical use. Owners recommend using a stiff carpet brush or a broom to work the powder into the pile.
The trade-off is that Capture is not a spot-treating spray. It works best as a maintenance powder for general cleaning and deodorizing rather than for isolated, wet stains. For fresh spills, a liquid enzyme cleaner is still necessary. Capture also requires a good vacuum with strong suction to fully remove the powder; leftover residue on dense plush carpets can attract dirt over time. For dry cleaning and odor neutralization without chemicals, it is a unique and effective tool.
What works
- No moisture means no wicking—old stains stay gone
- Safe for wool and Code S synthetic carpets
- Contains no bleach, solvents, or harsh chemicals
- Excellent for whole-room deodorizing and maintenance
What doesn’t
- Not suitable for wet spot cleaning of fresh spills
- Powder residue can accumulate on dense carpets if not vacuumed thoroughly
4. ANGRY ORANGE Pet Odor Eliminator
ANGRY ORANGE stakes its reputation on real cold-pressed orange oil rather than synthetic citrus fragrances. The NEW Orange Rush scent delivers a sharp, fresh burst that genuinely neutralizes strong pet odors—urine, feces, vomit—rather than simply covering them. The concentrated formula means a little goes a long way, with most users needing only a light spray to achieve odor elimination on carpets, tile, hardwood, and sealed concrete. It is formulated without parabens, sulfates, or phthalates, and proudly made in the USA.
Customer reviews are polarized but informative. Many users report complete removal of cat urine odor from carpets and car seats after a single application, including spots that had resisted steam cleaning and other enzyme sprays. A smaller group notes that the initial orange scent is very strong and requires good ventilation during application. One detailed review points out that if the concentrate is used at too high a ratio, it can leave orange-colored stains on light carpets, which are then removable with an oxygen-based cleaner.
The biggest practical issue is the spray bottle design. Multiple owners have reported that the bottle leaks or loses its spray mechanism after partial use, requiring a transfer to a different spray bottle. This is a quality-control frustration, but the liquid inside consistently delivers where it counts. For pet owners who prefer a bold, natural citrus scent and are willing to decant the product, ANGRY ORANGE is a high-performing option.
What works
- Natural orange oil provides genuine deodorizing power
- Highly concentrated—a small amount covers a large area
- Works on multiple surfaces beyond carpet
- No parabens, sulfates, or phthalates
What doesn’t
- Spray bottle often leaks or fails after a few uses
- Concentrate can stain light carpets if not used at the correct dilution
5. Resolve Pet Specialist Carpet Cleaner Spray
Resolve Pet Specialist is the most accessible, low-commitment entry point on this list. It uses OXI+Odor Stop technology to lift stains and neutralize odors on contact, and it is labeled as safe for use around pets and suitable for carpets, upholstery, and area rugs. The formula penetrates deep into carpet fibers to tackle fresh and old stains alike, and it is marketed as being effective on stains up to 7 days old.
Owner feedback is overwhelmingly positive for a budget spray. Multiple users report that it removed old cat vomit spots without discoloration, and one noted that it eliminated hidden odors that a previous cleaner had failed to address. The quick-drying nature is a consistent highlight—carpets are walkable in under 20 minutes. The spray nozzle delivers a wide, even mist that avoids over-saturating any single spot.
The main difference between this and the top two picks is the cleaning mechanism. Resolve relies on oxygen-based surfactants and odor-absorbing molecules rather than live enzymes. It will lift dirt and neutralize smells effectively, but it does not biologically break down organic matter like a true enzyme cleaner does. For households with occasional accidents rather than chronic pet issues, this is a solid, affordable choice. For deep-seated, repeated problems, an enzyme formula provides longer-lasting results.
What works
- Quick drying—carpets are usable within 20 minutes
- Effective on old stains up to 7 days old
- Wide, even spray pattern prevents over-saturation
- Pet-safe formulation rated for upholstery and area rugs
What doesn’t
- Uses oxygen surfactants rather than true enzyme activity
- May require multiple applications on very old or set-in stains
Hardware & Specs Guide
Enzyme Concentration
Not all “enzyme” cleaners contain the same level of active biological catalysts. Premium enzyme formulas like naturally it’s clean and BugMD list plant-based enzymes as the primary active ingredient, indicating a higher concentration of protease and amylase that directly break down protein and carbohydrate stains. Budget sprays often list enzymes further down the ingredient panel, diluting their effectiveness on organic matter.
pH Neutrality & Carpet Safety
Carpet fibers—especially wool and polypropylene blends—are sensitive to alkaline cleaners. A pH-neutral formula (6.5–7.5) prevents fiber degradation, color loss, and sticky residue buildup. The naturally it’s clean and BugMD formulas both test as pH neutral. Dry powders like Capture are inherently pH-neutral because they do not use water as a solvent. Always check the pH range before applying to a wool or sisal carpet.
