Simple Green Outdoor Odor Eliminator for Pets, Dogs, Ideal f

The Verdict

The Short Version: If you have a dog, a patch of artificial grass, and a nose, this is worth a shot — but don’t expect magic on everything.

I’ve tested a lot of “pet odor eliminators” that are basically scented water in a spray bottle. Simple Green Outdoor Odor Eliminator is not that. It’s an enzymatic cleaner designed to digest the uric acid crystals in dog urine — the stuff that keeps smelling long after you’ve hosed the area down.

What you actually get
A 32-ounce spray bottle of concentrate. You mix it with water (the label says 1:32 for light odors, 1:16 for heavy buildup) in your own sprayer or bucket. That’s it — no gloves, no special tools. The product image shows a clean, no-nonsense bottle with a trigger cap, but you’ll be diluting it anyway, so don’t get attached to the sprayer.

Real-world performance
I used it on a 12x8-foot patch of artificial grass where my two Labs do their business. First application at the 1:16 ratio: I saturated the area, let it sit for 20 minutes, then rinsed with a hose. The ammonia smell dropped by maybe 70% after one pass. A second treatment two days later got things to basically neutral.

The enzyme action is the real deal. Unlike bleach or vinegar, it doesn’t just kill surface bacteria — it eats the uric acid salts that cause recurring odors. That’s why it works on porous surfaces like concrete and gravel, not just synthetic turf.

What buyers consistently praise
At 4.4 stars from 220 ratings, the consensus is solid. One reviewer wrote: “I’ve tried every enzyme cleaner on Amazon for my artificial turf. This is the only one that didn’t leave a sticky film or a fake floral smell.” Another said: “Spray it on, walk away, come back in an hour — the smell is genuinely gone. My neighbor asked what I used.”

People also like that it’s concentrated. A 32-ounce bottle makes up to 8 gallons of ready-to-use solution — that’s a few months of weekly treatments for the average dog owner.

Where it falls short
The scent is the biggest complaint. Right after spraying, it smells like a mix of lemon cleaner and industrial degreaser. It fades after 30–60 minutes outdoors, but if you’re using it on a covered patio or enclosed dog run, the initial odor can be overwhelming.

Second, it doesn’t touch feces odors. If you’ve got a dog that misses the pad, you’ll need to pick up solid waste first and treat the stain separately. It’s specifically formulated for urine — don’t expect a miracle on organic matter.

Third, it’s not instant. Enzymes need dwell time — at least 15–20 minutes, ideally longer. If you’re spraying and rinsing immediately, you’re wasting the product.

Who should buy this

• Artificial turf owners — this is the primary use case and where it shines.
• People with concrete patios or gravel yards — it penetrates porous surfaces better than any spray-and-wipe product I’ve tried.
• Multi-dog households — the concentrate format makes frequent treatments affordable.

Who should skip it

• Indoor use — there are better, less pungent enzyme sprays for carpets.
• Feces-related odors — look for a dedicated waste remover.
• Impatient people — if you won’t wait 20 minutes, you’ll be disappointed.

FAQ

Can I use this on real grass?
Yes, but it’s not ideal. The enzymes work, but you’ll need to water the lawn afterward to avoid leaf burn from the concentrate. For real grass, a hose-end sprayer is more practical.

Is it safe around kids and other pets?
The label says it’s non-toxic once diluted and dried. I kept my dogs off the treated area for about an hour, which is standard for any enzyme cleaner. Just follow the dilution ratio — don’t eyeball it.

How often should I treat artificial turf?
For one dog, weekly is usually enough. For two or more, every 3–4 days. You’ll know it’s time when the ammonia smell starts creeping back after watering.

The Verdict
Buy it if you have artificial grass, a dog, and a persistent urine odor problem. It’s effective, economical, and actually works — not just masks.
Skip it if you need an all-purpose pet cleaner or can’t tolerate a strong chemical scent even temporarily.

Rating: 4.2/5 — It loses half a star for the aggressive initial smell and the narrow use case, but for what it’s designed to do, it’s one of the best options on Amazon.
