You installed artificial turf to make your backyard low-maintenance and beautiful. And for a while, it was. Then your dog discovered it — and now, especially on a warm day, stepping outside means getting hit with that unmistakable ammonia smell that no amount of hosing down seems to fix.
You're not imagining it. Dog urine and artificial turf are a notoriously bad combination. But the good news is that the smell isn't permanent — you just need to understand why it happens before you can actually fix it.
Why Dog Urine Smells So Bad on Fake Grass
Real grass has a natural ecosystem of microbes in the soil that slowly break down urine over time. Artificial turf doesn't have that. Instead, urine soaks down through the blades, past the infill, and collects in layers underneath — where it sits, concentrates, and crystallizes.
The culprit is a compound called urea, found in all urine. As urea breaks down, it releases ammonia — that sharp, eye-watering smell. On fake grass, urea crystals build up over months and even years of use, which is why the odor gets worse over time and why simply spraying the turf with water doesn't solve it. You're just diluting the surface while the crystals underneath stay put.
This is also why most sprays and enzyme cleaners only work temporarily: they mask the smell or break down a thin layer on top, but they can't penetrate deep enough to address the crystals that have been accumulating since your dog first started using that corner of the yard.
Why Enzyme Cleaners Often Fall Short
Enzyme-based cleaners are commonly marketed as the go-to solution for pet odor. They work by releasing enzymes that chemically break down urine compounds — but enzymes are fragile. They break down quickly in heat, sunlight, and dry conditions. In Arizona, Southern California, Texas, or anywhere warm and sunny, enzyme cleaners often lose their effectiveness before they can do their job.
They're also a one-and-done solution: once the enzymes finish their reaction, they're gone. There's no ongoing protection between applications.
The Smarter Solution: Microbes That Eat the Odor at Its Source
This is where microbial science changes the game. Instead of masking odors or using fragile enzymes, Pee Hero uses live, naturally occurring microbes — over 3 trillion per application — that specifically feed on urea crystals.
Here's what makes microbes different:
- They eat the actual source of the smell. The microbes consume urea and convert it into water and carbon dioxide — an odorless gas. The smell isn't masked. It's gone.
- They multiply. Every 20 minutes, the microbes double in number. The longer they're active, the more ground they cover — which is why Pee Hero keeps working long after you've sprayed it.
- They go dormant and reactivate. If your dog pees in the same spot between applications, the microbes already present wake back up and get back to work. This gives you ongoing protection, not just a one-time fix.
- They survive the heat. Unlike enzymes, Pee Hero's microbes are formulated for outdoor stability and remain effective in temperatures up to 100°F — making them ideal for hot patios, sun-baked turf, and warm climates.
The microbes in Pee Hero are CDC Biosafety Level 1, meaning they're non-pathogenic, non-toxic, and naturally occurring in soil and water. They're safe for your pets, your kids, your plants, and marine life. No carcinogens. No harsh chemicals. 100% biodegradable.
How to Use Pee Hero on Artificial Turf
Pee Hero is a highly concentrated formula — 16x professional strength — so a little goes a long way. Here's the process:
Step 1: Mix Pee Hero with water
Add the concentrate to water in a pump sprayer to activate the microbes. This is what wakes them up and starts them multiplying. Do not use a hose-end sprayer — it dilutes the product too fast and doesn't give the microbes time to activate properly.
Step 2: Pre-wet the turf
Lightly spray the smelly area with plain water from your hose. This opens up pathways through the infill so the microbes can reach the urea crystals below the surface.
Step 3: Apply Pee Hero generously
Spray the activated Pee Hero mix heavily over the area. You want good saturation so the microbes can penetrate deep into the turf and infill where the crystals have built up.
Step 4: Repeat daily for 5–14 days
If your dog has been using the same spot for months or years, there are a lot of urea crystals to eat through. Daily applications for the first 1–2 weeks let the microbes build up their colony and work through the accumulated buildup. Most customers notice a significant difference within the first week.
Maintenance phase
Once the smell is gone, switch to 1–2 applications per week to keep enough active microbes on the turf to stay ahead of new deposits. Adjust based on the size of your dogs and how heavily the area is used.
How Much Pee Hero Do You Need?
One gallon of mixed solution covers approximately 250 square feet — but you don't need to treat your whole yard. Focus on the spots where your dog actually goes. Dogs are creatures of habit and tend to return to the same areas repeatedly, which is exactly why those spots build up the most crystals.
Because Pee Hero is a concentrate, it's also significantly more cost-effective than pre-diluted products. One gallon of Pee Hero concentrate is equivalent to 16 gallons of ready-to-use product — working out to about $8.75 per gallon compared to $25+ per gallon for most competitors.
Real Results from Real Dog Owners
"I have tried SO MANY solutions I have lost count. After the initial 3 or 4 applications you couldn't smell that terrible dog pee smell! I immediately ordered the larger gallon option for continued use on our turf."

Which Pee Hero Is Right for You?
Pee Hero comes in three options depending on the size of your space and your dogs:
- Pee Hero Starter Kit — $59.95: The best way to start. Includes the concentrate plus a gallon pump sprayer so you have everything you need right away.
- 16 oz Concentrate — $33.50: Great for smaller areas or a single dog. A good option if you already have a sprayer.
- 1-Gallon Concentrate — $149.95: The best value for larger yards, multiple dogs, or ongoing maintenance. Most customers with turf upgrade to this after their first purchase.
All orders come with a money-back guarantee — if it doesn't work for you, reach out and Pee Hero will issue a full refund. No questions asked.
Stop Avoiding Your Own Backyard
Artificial turf is supposed to make your outdoor space easier to enjoy — not harder. If dog urine odor is keeping you from having people over, letting the kids play outside, or just sitting in your own backyard, it's time to fix it at the source.
Pee Hero's mighty microbes are the only solution that actually eats the urea crystals causing the smell — leaving your turf, and your nose, in peace.
