Just a quick update tacked onto the end of this thread for anyone interested. I decided to cover all bases LOL.
I ordered a diluting spray hose attachment in order to be able to spray product properly diluted directly on the lawn. It hasn't arrived yet, so we are still using a watering can.
Currently using Mistral Odourfresh. It didn't seem to be working until I realised that I should also 'water' the artificial grass immediately after application in order for it to work through the grass and into the sand, through the turf etc. The extra rain the past few days has helped. Hubby went out and applied it in the rain on Friday night and that really got rid of the odour. There wasn't much, he couldn't smell it, but I'm hyper sensitive to it, and worried about the neighbours.
I have ordered some YardFresh +Plus to try, but it is so much more expensive than the Odourfresh, so we'll have to see. And we've also picked up a bio washing liquid which we haven't tried yet. Mostly waiting on the sprayer to arrive.
Success
Thanks so much for all the info on this thread. It was truly helpful!
(ps - my friend who has had some in her enclosed dog run for 7+ years now and has several dogs uses Crommesol sp? on hers with a diluting sprayer, and has never had any odour issues and the grass is like the day it was installed)
