Artificial grass promises a pristine, low-maintenance lawn, but the reality for pet owners often involves a lingering, stubborn odor of ammonia and urine that no amount of hosing seems to fix. The bacteria from pet waste seeps into the turf backing, creating a smell that worsens in the heat and turns your backyard retreat into an unpleasant chore zone.
I’m Rikta — the co-founder and writer behind FitlyFast. I’ve spent countless hours researching the chemistry behind bio-enzymatic cleaners and granular infills, analyzing dozens of formulations to find which ones actually break down the uric acid crystals that cause the smell, rather than just covering it up with perfume.
Whether you’re dealing with a small balcony potty patch or a full-sized play area, finding the right artificial grass cleaner makes the difference between a fresh-smelling yard and an overpowering nose assault every time you step outside.
How To Choose The Best Artificial Grass Cleaner
The market is full of sprays, powders, and concentrates, but not all of them can handle the unique challenge of synthetic turf. The porous backing and dense fibers trap moisture and bacteria, creating a perfect environment for odor to thrive. Choosing the right cleaner comes down to understanding the difference between masking and eliminating.
Enzyme vs. Granular: Know Your Weapon
Liquid enzyme-based cleaners (like BioS+) work by digesting the organic waste at a molecular level. They are the heavy lifters for deep cleaning and are best when you need to tackle established smells. Granular infills (like BioTurf or Smelleze) work passively, absorbing moisture and ammonia over days or weeks. They are ideal for maintenance between liquid treatments, but they won’t fix a deeply saturated turf pad on their own.

In‑Depth Reviews
1. Eco Strong Outdoor Odor Eliminator
This is the all-around champion for anyone with an artificial grass lawn and multiple dogs. The bio-enzymatic formula uses natural enzymes to digest the uric acid crystals that cause that stubborn ammonia smell, and it does so without the harsh chemical sting that can irritate your pet’s paws. Users consistently report that it works within hours on heavily saturated turf where other sprays failed completely.
The super-concentrated nature means a single treatment can last up to several weeks, even with daily use from three large dogs. It leaves behind a light eucalyptus scent that is far more pleasant than the cloying perfumes found in many competing products. For a 16×20 foot turf area, most users find the 128 oz bottle lasts through multiple applications.
Eco Strong is also versatile enough for patios, decks, and kennels. The key advantage here is that it is specifically formulated to be paw-safe and barefoot-safe, which matters if your dog likes to roll around after a treatment. This is the one to buy if you want a proven, one-bottle solution that handles both deep cleaning and maintenance.
Why it’s great
- Enzymes digest ammonia at the source, not just mask it.
- Long-lasting effect—multiple weeks per treatment.
- Eucalyptus scent is fresh without being overpowering.
Good to know
- Premium tier; mid-range budget options exist.
- Heavy rain may shorten the time between applications.
2. Stuart Pet Supply Artificial Turf Cleaner Concentrate
Stuart Pet Supply’s concentrate is designed for convenience. It is an enzyme-powered formula that you can mix with water and apply using a standard hose-end sprayer, which makes covering a large yard or turf run in minutes. The bottle is 128 fluid ounces of concentrate, and users report that less than half the bottle treats a 16×20 foot area, making it a solid mid-range option.
One of the standout qualities is its safety profile. The formula is free of harsh chemical smells and is safe for both cats and dogs. It works particularly well on artificial turf and concrete patios, and multiple user reviews highlight that it eliminates odor permanently, rather than having the smell return after a day or two. The light minty scent left behind is subtle and pleasant.
The main trade-off is that it requires a separate hose-end sprayer (sold separately) to be used optimally. Without one, you can still use a pump sprayer or a watering can, but the dilution ratio is easier to manage with the sprayer. If you already own a sprayer, this is an efficient and effective choice that punches above its weight in the mid-range category.
Why it’s great
- Great coverage per bottle for the mid-range price.
- Light mint scent with no chemical odor.
- Safe for all pets and surfaces.
Good to know
- Requires a separate hose-end sprayer.
- May need monthly reapplication in rainy climates.
3. BioTurf BioS+ Turf Cleaner Concentrate
BioS+ is the heavy artillery for artificial grass owners dealing with stubborn, years-old urine smells. This concentrated bio-enzymatic formula is specifically designed to digest the organic waste that gets trapped in the turf backing and drainage layer. Users with large breed dogs and high-traffic potty areas report that this product completely eliminates lingering smells that other cleaners only masked.
The formula is plant-based, non-toxic, and safe for kids, pets, and plants. It can be diluted and used in a sprayer for the turf, or even applied directly to indoor carpets and litter boxes. One of its strongest selling points is its effectiveness in hot climates—users in Florida and Texas note that it does not break down or lose potency in the summer sun.
The primary consideration is that this is the premium end of the scale, and some users find the scent to be a bit stronger than other enzyme cleaners. For the most severe odor situations, BioS+ is often the only solution that works, and many users pair it with the BioTurf Granular Infill (next on the list) for an unbeatable one-two punch.
Why it’s great
- Digests deep-set organic waste, not just surface smells.
- Works in extreme heat without losing effectiveness.
- Versatile: also works indoors on carpets and litter boxes.
Good to know
- Premium price per gallon.
- Scent may be stronger than some prefer.
4. ProVetLogic Kennel & Turf Care
ProVetLogic’s offering is unique because it is formulated as both a turf deodorizer and a drain maintainer. In addition to controlling ammonia odors on synthetic turf and concrete, it actively degrades organic waste in drains, which is a common source of smell in kennel and patio environments. This makes it a smart choice for multi-dog households with outdoor drains near the turf area.
The formula is environmentally friendly and non-toxic, which is important if you have pets that lick surfaces or if the runoff goes into your garden. Users report that it works very well on heavily contaminated areas, with one user noting it took away a heavy urine buildup on turf grass completely. It also works on a wide range of surfaces including rubber mats, brick, and grout.
The one downside is that a foam gun applicator is sold separately, and purchasing one adds to the initial cost. The concentrate itself is versatile and effective, but if you don’t already have a sprayer, the investment might feel steep for the entry-level price tier.
Why it’s great
- Dual-purpose: turf cleaner plus drain maintainer.
- Works on concrete, rubber, tile, and multiple surfaces.
- Environmentally friendly and non-toxic.
Good to know
- Foam gun applicator sold separately.
- Mid-range price for the concentrate only.
5. BioTurf Granular Turf Infill
BioTurf Granular Turf Infill is the go-to product for ongoing maintenance and preventative care. Instead of applying a liquid, you simply sprinkle the naturally derived granules evenly over the turf and brush them in. The granules act like a sponge, absorbing moisture and breaking down ammonia compounds on contact over days and weeks.
This product is ideal as a complement to a liquid enzyme cleaner. Many users apply BioS+ enzyme concentrate first for a deep clean, then follow up with the granules to keep the smell at bay between applications. The granules are weather-resistant; normal moisture activates them, though heavy rain may require a touch-up. A single gallon pail can last several months for a small to mid-sized lawn.
The biggest advantage is the ease of use—no mixing, no sprayers, just sprinkle and brush. It’s safe for pets and kids immediately after application. The trade-off is that it is less effective on already deeply saturated turf; it truly shines as a maintenance tool rather than a rescue product. If you are starting fresh and want a low-maintenance routine, this is the pick.
Why it’s great
- No mixing or spraying required—just sprinkle and brush.
- Weather-resistant for outdoor durability.
- Excellent as a complementary maintenance product.
Good to know
- Less effective alone on deeply saturated turf.
- May require monthly reapplication in heavy-use areas.
6. Simple Green Pro Outdoor Odor Eliminator
Simple Green’s Pro Odor Eliminator is a commercial-grade enzyme cleaner that is designed for heavy-duty use. One gallon of concentrate makes up to 17 gallons of cleaning solution, making it one of the most cost-effective options for large turf areas, farms, and athletic facilities. It uses advanced natural enzymes to neutralize organic odors rather than masking them.
The citrus scent is a standout—users consistently describe it as fresh without being overwhelming. It works on both indoor and outdoor surfaces, and users report it effectively eliminates even the strongest neighborhood dog urine smells from plants, sidewalks, and trees. For turf specifically, it handles the job well, though some users note it takes a generous amount for deeply saturated areas.
The main trade-off is that the citrus scent, while pleasant, may not last as long as the mint or eucalyptus scents found in other products. Additionally, for very large turf areas, the cost of the one-gallon concentrate may be higher up front, but the dilution ratio makes it economical over time. It is a solid choice for those who need a versatile cleaner for multiple surfaces beyond just turf.
Why it’s great
- Extremely cost-effective dilution: 1 gallon makes 17 gallons.
- Works on turf, plants, concrete, and more.
- Pleasant citrus scent, not chemical-smelling.
Good to know
- Scent may fade faster than mint-based competitors.
- May need heavy application for very saturated turf.
7. Smelleze 2 lb. Yard Odor Eliminator
Smelleze is a granular odor eliminator that operates on a different principle than enzyme cleaners. It is made from a naturally occurring, porous earth material that acts like a magnet and sponge for odor molecules. You simply sprinkle it on the affected area, and it draws in urine, fecal, and ammonia odors, absorbing them safely without any scent cover-up.
One of the most unique features is that Smelleze can be automatically rejuvenated in sunlight and heat. Even after getting wet from rain, the sun reactivates the granules, extending their lifespan. This makes it a very low-maintenance option for small turf patches, gravel potty areas, and kennels. It is also fragrance and cruelty-free, safe for people, pets, and the planet.
The main consideration is that the 2-pound bag is best suited for small areas like a balcony potty patch or a kennel corner. For larger turf lawns, you will need to buy larger bags more frequently, which can add up. Some users also note that the effect is temporary in high-traffic areas, requiring reapplication every few days initially. It is a great entry-level option for testing if a granular infill approach works for your setup.
Why it’s great
- All-natural, non-toxic, and fragrance-free.
- Rejuvenates in sunlight for extended use.
- Works on gravel, grass, and patios, not just turf.
Good to know
- 2-pound bag is best for small areas only.
- May need frequent reapplication for heavy daily use.
