We have a pitbull that runs freely on the turf in our back yard. I tried multiple products to get rid of the urine smell. Including a major brand sold at major hardware stores. It made the smell worse. OxyTurf worked instantly. My wife is a work from home hairdresser, she has a separate entrance for clients and the last thing she wants is her clients to get a wiff of dog urine. The sprayer is super convient. If you have a large amount of turf I suggest a backpack sprayer to save your back. Returning customer here.
