If you have dogs and synthetic turf, you’ve probably already discovered the one maintenance challenge that comes with the combination: urine odour. The good news is it’s entirely manageable — but only if you’re using the right product. Most off-the-shelf cleaners don’t actually solve the problem. Enzyme-based cleaners do. Here’s why, and how to use them properly.

Why Dog Urine Smells So Persistent on Synthetic Turf

To understand why enzyme cleaners work so well, it helps to understand what you’re actually dealing with. Dog urine contains uric acid — a crystalline compound that doesn’t dissolve easily in water. When your dog urinates on synthetic turf, the liquid drains through the backing, but uric acid crystals bind to the turf fibres and backing material. Left there, bacteria break the uric acid down into ammonia — and that’s the sharp, lingering smell that tells you the problem isn’t going away on its own.

The critical thing to understand is that uric acid doesn’t simply wash away with water. You can hose the area down as many times as you like, and while it will temporarily reduce the smell, the uric acid crystals remain. The next time moisture hits the area — rain, dew, or another hose-down — the bacteria reactivate and the smell returns. This is why dogs also keep returning to the same spots: the odour signal is still there even when you think you’ve cleaned it.

Standard household cleaners and disinfectants have the same limitation — they kill surface bacteria and temporarily mask odour, but they don’t break down the uric acid compounds causing the problem in the first place.

How Enzyme Cleaners Actually Work

Enzyme-based cleaners work on a completely different principle. Rather than masking or disinfecting, they break down the problem at a biological level. The cleaners contain specific enzymes — including protease, uricase, and lipase — that act as biological catalysts, latching onto the uric acid, proteins, and ammonia compounds in pet urine and breaking them down into harmless byproducts: essentially water and carbon dioxide.

The result isn’t a reduction in odour — it’s the elimination of the compounds causing it. Once those compounds are broken down, there’s nothing left to smell. And because the uric acid crystals are gone, dogs are no longer drawn back to the same spots by lingering scent signals.

This is the key difference: other cleaners work on the symptom (the smell). Enzyme cleaners work on the cause (the uric acid and bacteria producing the smell).

Are Enzyme Cleaners Safe for Synthetic Turf, Pets and Kids?

Yes — and this is one of their major advantages over chemical alternatives. Quality enzyme cleaners are non-toxic, biodegradable, and free from harsh chemicals like bleach or ammonia. They won’t damage your turf fibres or backing, won’t discolour your grass, and are safe for pets and children once the treated area has been rinsed.

By contrast, bleach — a common go-to for odour problems — is genuinely harmful to synthetic turf. It can degrade the fibres over time, cause discolouration, and leave residues that are potentially harmful to pets walking on the surface. Bleach should never be used on synthetic grass.

The Product We Recommend: TrueEco Enzyme Concentrate

We stock and recommend TrueEco Enzyme Concentrate, a powerful, Australian-made enzyme cleaner specifically formulated for pet-related odour and staining. Unlike many enzyme cleaners sold in pre-diluted spray bottles, TrueEco comes as a 1-litre concentrate that makes up to 20 litres of ready-to-use cleaner — making it significantly more cost-effective for regular use.

It’s pet-safe, non-toxic, and designed to work in Queensland’s climate, where heat and humidity can accelerate bacterial growth and intensify odour problems. You can get it directly from TrueEco’s website — use the promo code AUGRASS for 20% off all products.

How to Use Enzyme Cleaners Correctly on Synthetic Turf

For the best results, follow these steps:

  1. Remove solid waste immediately. Don’t let it sit. Prompt removal stops contamination spreading into the turf fibres and backing.
  2. Rinse the area first. Give the affected area a good hose-down to flush away as much surface urine as possible before applying the enzyme cleaner. This gives the enzymes a cleaner surface to work on and improves results.
  3. Apply the enzyme cleaner generously. Don’t just mist the surface — apply enough to penetrate through the turf pile and into the backing where uric acid accumulates. This is where most of the odour originates.
  4. Allow dwell time. This is the step most people skip. Enzyme cleaners need time to work — allow at least 10–15 minutes of contact time before rinsing. If the area has a persistent odour from repeated use, allow longer. The enzymes need time to break down the compounds.
  5. Rinse thoroughly. After the dwell time, rinse the area well with a hose. The broken-down compounds will flush away with the water.

💡 Queensland tip: In summer, try to apply enzyme cleaners in the early morning or evening rather than the middle of the day. High temperatures can cause the product to evaporate too quickly during the dwell time, reducing effectiveness. If applying in direct sun, keep the area slightly moist during the dwell period.

How Often Should You Clean?

For a backyard with one or two dogs, a good routine looks like this:

If you’ve recently moved into a home with existing synthetic turf that has a pet odour problem, do one thorough enzyme treatment across the entire area before starting a regular maintenance routine. This resets the baseline and makes ongoing maintenance far easier.

Does the Type of Turf Make a Difference?

Yes — significantly. The backing system on your turf has a major impact on how well enzyme cleaners can do their job. Turf with poor drainage causes urine to pool in the backing rather than passing through, which means higher concentrations of uric acid in one area and a harder cleaning job.

Our K9 Cool Supreme features a 100% permeable backing rated to 120 litres per minute — liquid drains straight through without pooling, which means lower concentration of uric acid in the backing and a more effective result from your enzyme cleaner. Our Austral II Pet Friendly+ 30mm features a bacteria-resistant double PU backing that actively resists the bacterial growth that causes odour in the first place.

If you’re using enzyme cleaners on an older or lower-quality turf and still struggling with persistent odour, the backing may be the limiting factor — no cleaner can fully compensate for a backing that traps urine rather than draining it.

What About Vinegar?

White vinegar is often recommended as a natural alternative and it does have some merit for light, regular maintenance — it’s cheap, non-toxic, and mildly acidic, which helps neutralise ammonia odours. A 1:1 mix of white vinegar and water applied and rinsed is a reasonable option for a quick freshen-up between enzyme treatments.

However, vinegar doesn’t break down uric acid the way enzyme cleaners do — it neutralises ammonia smell temporarily but doesn’t eliminate the underlying compounds. For a backyard with regular dog use, vinegar alone won’t be enough long-term. Use it as a supplement to enzyme cleaning, not a replacement.
