How to eliminate the smell of dog urine from artificial grass
By Gavin Hall
With summer here and the occasional spell of lovely dry weather I am getting asked by more and more people about how to remove the smell of dog urine from an artificial grass lawn.
Basically what is happening in the summer months is the lower levels of rain is causing the ammonia from the dog urine to become more noticeable leaving the garden owner with a great looking lawn that smells.
For years I have tried and tested many products to find the best answer to this problem. I will go into more details on some of the products I have tried below. I will also reveal what I think is the best, environmentally and pet friendly solution to rid you’re lawn of the smell of urine.
To give you a little background to my testing I have 3 male dogs of my own and a medium to small sized back garden lawn (25m2) fitted with the Spring artificial grass product. I have installed the artificial lawn in exactly the way shown in my blogs. The tests have been conducted over the last 12 months since I fitted this product.
– Jeyes fluid outdoor disinfectant
An established cleaning brand that offers a general outdoor disinfectant. The main problem with this product is that I found it was far too pungent leaving me with another smell to get rid of.
– Washing the artificial turf with a high pressure water hose
This consumes a lot of water and needs to be done regularly in the dry months. A problem if there is a hose pipe ban.
– Reosan janitorial cleaner
I found it works well but it leaves a sweet smell of bubblegum.
– Zoflora disinfectant
This works well diluted in water.
– Rinsing the grass with diluted white vinegar
I left this on for 10 minutes before rinsing off. It leaves a vinegary smell and the urine smell is quick to return.
– Cleaners that smell of grass
They quite simply make the smell worse.
If you look on the Internet there a literally hundreds of so called ‘urine cleaning products’ on the market. I have tried many but I have found that the products I have tried will get rid of the smell by covering it up and the odour will return in days.
The method that I have found that works best to eliminate the smell of dog urine without just covering it up
First things first the grass needs to have been laid correctly:
– A good membrane
A good membrane needs to be placed underneath the foundations of the artificial grass not directly under the grass, as this will simply trap the urine.
– A good sub base
There must be a good solid sub base of Type 1 followed by a top layer of granite dust. This will enable better drainage and give the urine the chance to soak through.
– A fine top dressing
I have been testing a very fine sand top dressing that I have called ‘Artificial Grass Dog Wee Sand‘ over the last 3 months. I simply sprinkle it on top of the artificial grass and brush it in with a plastic leaf rake. I don’t use a metal rake as it will pull out the fibres from the artificial grass. I have found the sand absorbs the urine and holds on to the odour and it really really works. I don’t know the scientific explanation for this but I highly recommend it.
I have only applied it once in the last 3 months during this very dry period so it’s not a question of having to do it every time it rains.
You can see details of the product here. Because of the size and weight (20kg bags) the product it is collection only. Please call first.
If you are getting artificial turf laid in your garden and you have dogs or other pets make sure you ask your installer how they intend to deal with the potential issue.
