pet odor – Complete Review 2026
Tackling tough pet odor in my backyard has felt like a never-ending battle, especially with two dogs and a stretch of artificial turf that loves to trap smells. When I ordered the Simple Green Outdoor Odor Eliminator, I was hopeful but skeptical. The box arrived with a hefty 1-gallon refill and a 32 oz hose-end sprayer. My first impression was positive; the sprayer felt sturdy and well-made, not like the flimsy plastic nozzles that break after one season. I was dealing with a persistent dog urine smell on my patio, and I was eager to see if this was the solution to my nagging pet odor problem.

What Makes This outdoor pet cleaner Stand Out?
Right away, I was drawn to the fact that this is an enzyme cleaner. Instead of just masking smells with a heavy floral scent, it uses powerful, natural enzymes to break down and eliminate the source of the pet odor. According to the Simple Green Store, the formula is designed to digest the organic matter in pet waste, which is exactly what I needed. I found this claim held up in my testing. It’s not just for grass; I used it on my concrete patio and a gravel dog run, making it a versatile concrete cleaner and dog run cleaner in one. The fact that it’s specifically formulated to be safe for pets and plants gave me peace of mind, as my dogs were back to playing in the yard shortly after it dried.
Real-World Performance Testing
My main testing ground was a 10×15 foot patch of artificial turf that gets direct sun all afternoon—a perfect recipe for baked-in artificial grass odor. Hooking up the hose-end sprayer was a breeze. It attached securely without any leaks, and the spray pattern was wide and even. I saturated the entire turf area and the surrounding brick patio. The product has a fresh, clean scent that isn’t overpowering. I left it to work its magic overnight. The next morning, I was genuinely surprised. The sharp, ammonia-like dog urine smell was completely gone. The air just smelled neutral and clean. My only small gripe is that the 32 oz bottle can feel a bit top-heavy when you’re trying to do more detailed spraying, but for broad coverage, it’s fantastic. This is a powerful patio odor remover that actually works and has solved my most stubborn pet odor issues.
Who Should Buy Simple Green Outdoor Odor Eliminator?
Based on my experience, I’d recommend this product to a few specific types of people:
- The Artificial Turf Owner: If you’ve invested in turf and are fighting that specific, hard-to-remove artificial grass odor, this is your new best friend. It penetrates the turf backing to eliminate the problem at its source. For more tips on creating a pet-friendly space, check out our guide on Barkitecture and pet-friendly landscaping.
- The Multi-Dog Household: For those with multiple dogs or dedicated outdoor areas like dog runs, this is an economical and effective way to manage heavy-duty pet odor. The gallon refill is a must-have.
- The Eco-Conscious Pet Parent: If you need a powerful urine remover but want to avoid harsh chemicals, this is an excellent choice. Its use of natural enzymes makes it a solution that is safe for pets and your yard. A healthy home is key, which you can learn more about in our Healthy Pet-Ready Living Guide.
pet odor vs Competitors
I’ve used my fair share of odor eliminators, and Simple Green holds its own. Compared to Nature’s Miracle Advanced Stain & Odor Eliminator, which I’ve used for spot treatments, the Simple Green hose sprayer is far superior for covering large outdoor areas quickly. Rocco & Roxie Supply Co. makes a fantastic enzyme cleaner for indoor use, but for the scale and intensity of outdoor pet odor, Simple Green is more practical and cost-effective. Many competitors also have strong chemical smells, whereas Simple Green’s scent is much lighter and dissipates faster, leaving just neutrality behind.

Frequently Asked Questions
- Is this enzyme cleaner safe to use on a wooden deck?
- In my experience, yes. I tested a small, hidden patch on my stained cedar deck before going all out, and I saw no discoloration or damage. I always recommend testing a small spot first, but it was perfectly safe for me.
- How long does it take to eliminate a strong dog urine smell?
- I found that for surface-level pet odor on my patio, the smell was gone within a few hours after the product had dried. For the deeper-set smells in the artificial turf, it was a dramatic improvement overnight. The key is to thoroughly saturate the area.
- Can this be used as a general outdoor pet cleaner?
- Absolutely. I used it to wash down my dog’s kennel and the concrete pad it sits on. It worked wonderfully as a general-purpose dog run cleaner, removing that lingering musky dog smell effectively.
- Is this truly a better solution than other products for pet odor?
- For large outdoor spaces, I believe it is. The combination of the effective enzyme formula and the easy-to-use hose attachment makes tackling widespread pet odor much simpler than spot-treating with a spray bottle.
