Maintaining a pristine backyard is a major draw for installing synthetic turf, especially in Australia where water conservation and low maintenance are top priorities. However, many homeowners are surprised when their evergreen lawn starts emitting a less-than-pleasant odour.

If your fake grass has developed a bit of a "pong," you aren't alone. Here is a breakdown of why synthetic turf smells and how you can reclaim your fresh outdoor space.

The Culprits Behind the Smell

Unlike natural grass, synthetic turf is non-porous. While the backing is designed for drainage, the blades themselves are made of plastic (polyethylene or polypropylene), which can trap residues.

1. Pet Waste (The Most Common Cause)

The primary reason for smelly turf is pet urine and faeces. While you likely pick up the solid waste, urine can seep into the infill—the sand or granules used to keep the blades upright. If not flushed away properly, the urea breaks down into ammonia. In the Australian sun, this process accelerates, leading to a sharp, pungent smell that lingers in the heat.

2. Trapped Organic Debris

Falling leaves, grass clippings from nearby mown areas, and even dead insects can get trapped between the synthetic fibres. When these organic materials get wet from rain or morning dew, they begin to decay. This decomposition creates a musty, earthy, or even rotting smell.

3. Poor Drainage and Mould

If your turf wasn't installed with a proper crushed rock base, water can pool underneath the backing. This stagnant water, combined with trapped dust and dirt, becomes a breeding ground for mould, mildew, and bacteria.

How to Get Rid of the Odour

Simply hosing down the grass with water often isn't enough, as it may just spread the bacteria further into the infill.

• Regular Flushing: Aim to give your turf a heavy rinse once a week, particularly in high-traffic pet areas.

• Remove Debris: Use a leaf blower or a plastic rake (avoid metal rakes as they can damage the fibres) to remove organic matter before it has a chance to break down.

• Use a Targeted Cleaner: To truly neutralise odours—rather than just masking them with a scent—you need a product specifically designed for synthetic surfaces. Our product, smellBgone SYNTURF has been specifically designed to  work by breaking down the uric acid crystals and bacteria at a molecular level, effectively "eating" the source of the smell.

Prevention is Key

To keep your backyard smelling like a sanctuary rather than a kennel, consistency is vital. Treating your lawn with smellBgone once a month (or more frequently in summer) will prevent the buildup of ammonia and keep your synthetic turf looking—and smelling—brand new for years to come.
