AMAZING PRODUCTS! We have a small backyard with artificial turf and 3 small gorgeous fur babies. The urine smell had been a problem for a while but once we welcomed our 3rd dog it was so bad I had to leave a bedroom window closed. I tried everything but nothing worked! I saw the Pet Lab products and I was very sceptical about making the investment, however, I went ahead and purchased the 300ml concentrate packs with the spray bottle! I watched the video and did exactly as they said (minus the tarp) over 2 days. That was 2 weeks ago in an Adelaide heatwave and the smell has gone! We are now enjoying our backyard again. I was expecting to have to do it twice initially as it was so bad but definitely not yet! I can’t recommend this product highly enough! It is simply AMAZING!
