Artificial grass traps urine, feces, and organic debris deep in the backing and infill, creating a stubborn ammonia odor that standard sprays and bleach-based cleaners can’t touch. Without the right enzyme or biological cleaner, that smell bakes into your turf under the sun and turns your backyard into an outdoor litter box.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent thousands of hours analyzing the chemical formulation, bacterial colony counts, and NSF-certification data of outdoor biological cleaners to separate the true odor-digesting solutions from the fragranced water.
After stress-testing enzyme potency, residue behavior, and application simplicity across five market-leading formulas, this buying guide delivers a clear verdict on the best artificial grass cleaner for pet owners who want real odor elimination, not just temporary masking.
How To Choose The Best Artificial Grass Cleaner
Synthetic turf requires a cleaner that targets biological waste at the molecular level rather than just adding a fragrance layer. The wrong formula can degrade the turf’s latex backing, clog drainage holes, or leave a sticky residue that attracts more dirt.
Enzyme vs. Bacteria: Which Biology Works Faster?
Enzyme-only formulas (like protease and lipase) begin breaking down protein and fat-based stains the second they make contact. Bacteria-based cleaners need time — typically 4 to 8 hours — for the colony to multiply and start digesting. For artificial grass where urine soaks into the backing, a concentrated enzyme formula offers faster relief for high-traffic pet zones.
Concentrate vs. Ready-to-Use: Cost Per Gallon Matters
A 32-ounce concentrate that dilutes to two gallons gives you significantly more coverage than a ready-to-use spray of the same bottle size. For large turf areas (200 square feet or more), buying concentrate and mixing in a garden sprayer dramatically improves your per-application cost and allows you to adjust strength for particularly stubborn spots.
The Drainage Factor: Residue and Foam
Artificial grass relies on its perforated backing and crushed stone base to drain liquids. Heavy, soap-based cleaners leave a surfactant residue that clogs drainage holes over weeks, causing puddling and trapped odors. A turf-safe cleaner should be low-foaming and leave zero sticky film behind after a light rinse.

In‑Depth Reviews
1. Nanoskin ENZYME Multi-Purpose Cleaner 1 Gallon
With a full gallon of ready-to-use enzyme solution, the Nanoskin ENZYME cleaner delivers the highest volume-per-dollar in this category. The enzyme cocktail targets complex organic stains — urine, feces, vomit, and grease — by breaking down the protein chains and fatty acids that produce ammonia odors. You don’t need to mix or dilute; just saturate the affected turf area and let the enzymes work over 10 to 15 minutes before a light rinse.
This formula is low-foaming and leaves no sticky film, which means the perforated backing and drainage gravel underneath the turf stay clear. The multi-surface claim extends beyond turf to concrete, patio stones, and even automotive upholstery, making it a versatile addition to your cleaning arsenal. The lack of added fragrances is a deliberate design choice — Nanoskin relies on the enzymatic digestion itself to eliminate odor rather than covering it with perfume.
For pet owners with multiple dogs or a large turf area, buying this by the gallon eliminates the anxiety of running out mid-treatment. The flip-top cap makes pouring into a garden sprayer fast and mess-free. While the product is marketed broadly, its enzyme concentration feels noticeably stronger than standard pet-spot sprays, requiring less dwell time on fresh stains.
Why it’s great
- Full gallon ready-to-use lasts through multiple deep-cleaning sessions
- Low-foaming formula protects turf drainage integrity
- Enzyme-only approach eliminates odor rather than masking it
Good to know
- No added fragrance; the enzyme smell is mild but present during application
- Overkill for small patios or single-dog households
2. Stuart Pet Supply Artificial Turf Cleaner Concentrate
Stuart Pet Supply’s formula is specifically designed for artificial grass, not just adapted from a carpet cleaner. The 32-ounce concentrate dilutes to two full gallons of working solution, giving you the longest coverage of any product in this lineup. The active ingredients include enzyme-producing bacteria that continue to digest waste for up to 72 hours after application — a unique slow-release mechanism that prevents odor rebound on days you don’t treat.
Application requires mixing with water in a pump sprayer or hose-end sprayer, but the dilution ratios are clearly printed on the bottle. The formula is pH-neutral and contains no bleach, chlorine, or heavy surfactants, so it won’t degrade the latex backing that holds your turf’s fibers in place. Users report that two treatments per week are sufficient for maintaining a 300-square-foot dog run.
This cleaner earned top marks for its “doggie doo dissolver” action — it softens dried feces so they can be rinsed away without scraping, which is a major convenience for owners who can’t pick up waste immediately. The concentrate format also means less plastic waste long-term, since one bottle replaces multiple ready-to-use spray bottles.
Why it’s great
- Concentrate makes two gallons for large turf coverage
- Slow-release bacteria prevent odor return for days
- pH-neutral and safe for artificial grass backing
Good to know
- Requires mixing and a separate sprayer
- Bacterial formula works slower than direct enzyme sprays
3. Rocco & Roxie Supply Co. Stain & Strong Odor Eliminator
Rocco & Roxie has built a strong reputation in the pet spot-cleaner market, and their enzyme formula translates well to artificial grass maintenance. The 32-ounce spray bottle is ready to use and targets urine and feces odors through a proprietary enzyme blend that includes protease and lipase. The cleaner is chlorine-free and contains no volatile organic compounds, making it safe for pets who like to roll on the turf immediately after cleaning.
This product shines on fresh stains where immediate application prevents the urine from crystallizing in the turf backing. The spray nozzle delivers a focused stream rather than a wide mist, which is ideal for spot-treating specific areas rather than drenching the entire lawn. Users note that it works well on both synthetic turf and the concrete or patio stones surrounding the turf area.
Where Rocco & Roxie falls slightly behind the larger-volume options is cost-per-ounce. For a home with multiple large dogs using turf daily, the 32-ounce bottle may require restocking frequently. It is, however, one of the most trustworthy brands in the pet-care space, with third-party testing backing their enzyme stability claims.
Why it’s great
- Trusted enzyme formula with proven stain-digestion capability
- Safe for pets and turf backing with zero harsh chemicals
- Convenient spray nozzle for spot treatment
Good to know
- Small bottle size may not suit large turf areas
- Pre-fragranced — some users prefer unscented enzyme cleaners
4. MICROBE-LIFT Outdoor Pet Odor Eliminator
MICROBE-LIFT takes a different approach from enzyme sprays: it uses live Bacillus bacteria that consume urea and uric acid crystals as a food source. This biological colonization means the product keeps working for days after the initial spray, and it actively discourages pets from re-marking the same spot by removing the chemical signature that tells them it’s a toilet zone. It’s formulated specifically for outdoor use on turf, patios, decks, and lawns.
The bacteria require moisture to activate, so you should apply on damp turf or mist the area lightly before spraying. The formula is non-toxic and won’t burn grass or harm synthetic turf fibers. The 32-ounce bottle covers roughly 150 square feet when applied as a fine spray, and the bacteria lay dormant in the bottle until exposed to air and water, giving it a long shelf life.
Feedback from users indicates that MICROBE-LIFT is particularly effective for breaking the cycle of repeated marking in the same corner of a yard. The deterrent effect is a unique benefit that enzyme-only products cannot claim. However, the initial odor elimination is slower — expect results within 24 hours rather than the 30-minute speed of a concentrated enzyme formula.
Why it’s great
- Bacteria colony continues digesting waste for days
- Deters pets from re-marking treated areas
- Non-toxic and safe for synthetic turf fibers
Good to know
- Slower acting than enzyme-based sprays
- Requires damp application for bacterial activation
5. Amazing Outdoor Deodorizer by Absolutely Clean
Absolutely Clean’s Amazing Outdoor Deodorizer uses natural enzymes derived from plant sources to break down animal waste odors on synthetic turf and surrounding surfaces. It is veterinarian-approved and completely free of harsh chemical fumes, making it a strong choice for pet owners with allergies or chemical sensitivities. The “spray and walk away” design requires no rinsing — the enzymes digest the waste, and the remnants are washed away by the next rain or sprinkler cycle.
The formula is manufactured in the USA by a small Colorado-based company, and the bottle uses minimal plastic weight compared to competitors. Users appreciate that it prevents grass yellowing around the edges of artificial turf, a common complaint when chemical deodorizers leach into the soil border. The spray works on chicken coops, dog runs, decks, and concrete, extending its usefulness beyond just the turf.
For small to medium-sized turf installations, this 32-ounce bottle provides roughly 10 to 12 treatments. It has a mild natural scent during application that fades quickly, leaving no perfume behind. While it lacks the bacterial persistence of MICROBE-LIFT or the concentrate value of Stuart Pet Supply, it is the gentlest option on this list and the most environmentally friendly.
Why it’s great
- Natural plant-based enzymes with no harsh chemicals
- Veterinarian-approved and safe for sensitive pets
- No rinsing needed — rain or sprinklers handle the rest
Good to know
- Small bottle volume limits coverage on large lawns
- Mild enzyme smell during application may be noticeable
