If you've installed artificial grass and you've got a dog, you've probably noticed it holds onto urine smell in a way real lawn never did. You hose it down, it smells fine for an hour, and by the afternoon it's back. That's not a sign you're cleaning wrong. It's just how artificial turf behaves.

A targeted urine odour neutraliser designed to treat animal urine smells at the source across carpets, rugs, tiles, bedding, kennels and artificial grass.
View Pissed Off™Why Artificial Grass Holds Urine Odour
Real lawn has soil underneath it, and soil disperses and breaks down urine naturally. Artificial turf doesn't have that. Urine passes through the blades and sits in the infill (the sand or rubber crumb layer underneath) or drains down to the base beneath it. There's nothing there to break it down, so it just accumulates.
As urine dries, it leaves behind urea and ammonia residue that clings to the infill. Heat speeds up how quickly that residue releases odour, which is why a toilet spot on artificial grass often smells worse by mid-afternoon than it did in the morning. Humidity does something similar, reactivating dried residue that was sitting quietly.
A hose rinse helps move some surface residue along, but it rarely gets deep enough into the infill to shift what's actually causing the smell.
This is where a targeted treatment step makes the difference. Pissed Off™ - Urine Odour Destroyer is formulated to neutralise urine odour at the source rather than mask it with fragrance. It's suitable for both hard and soft surfaces, including artificial grass, so it can go straight onto the toileting area without any special prep.
How to Treat Artificial Grass Urine Smell
The directions are straightforward, and they apply whether you're dealing with a fresh spot or one that's been building up for a while:
- Rinse the area first. A decent hose-down flushes loose surface residue and gives the treatment a clean area to work with. No need to scrub, just a proper rinse.
- Apply Pissed Off™ directly to the affected area. Once the turf isn't dripping wet, apply the product straight to the spot your dog regularly uses.
- Let it penetrate and air dry. This step matters more than it sounds like it should. The formula needs time to work down into the infill where the odour-causing residue actually sits, rather than being rinsed off too soon. It's alcohol-based and fast-drying, so it won't leave the area sticky or wet for long.
- Repeat as required. Toilet areas that get daily use will need more frequent treatment than the rest of the yard. If a spot has years of build-up, one application might not fully clear it, and that's normal. Treat again once it's dried and check.
- Why This Beats a Regular Hose Down
Citric acid and clove oil are the two ingredients doing the real work here. Citric acid targets the urea and ammonia compounds responsible for the smell, and clove oil helps remove the odour rather than covering it with a stronger scent. That's a meaningful difference on artificial grass specifically, because a fragrance spray on hot turf just adds a second smell on top of the ammonia, it doesn't get rid of it.

A Simple Routine for Toilet Areas
If your dog has a spot they consistently use, a light routine keeps it under control without much effort:
- Hose the area after use, or once a day at minimum
- Treat with a targeted odour neutraliser a few times a week in the toilet zone, more often in hot weather
- Give the rest of the turfed area an occasional treatment too, since dogs don't always stick to one exact spot
Keeping your dog to one general toileting area, rather than the whole lawn, also makes this a lot more manageable. It concentrates the smell into one zone you can treat properly instead of spreading it across the whole yard. The RSPCA notes that a consistent routine and a designated area are useful parts of managing pets in shared outdoor spaces.
The Bottom Line
Artificial grass doesn't have the soil that real lawn relies on to break urine down, so residue just sits and builds up in the infill. Rinsing keeps it manageable day to day, but the actual smell needs a treatment built to neutralise urea and ammonia at the source. Applied directly to the toilet area, left to penetrate, and reapplied as needed, that's really the whole routine. If your current approach has stalled, the urine odour range is worth trying on the spot your dog uses most.
