How long does the pet odor neutralizer last?

It will depend on the following factors:

How many dogs are doing their business on the turf.
How hot or warm of the weather (the higher the temperature, the more of the smell) Typically, it will last you at least couple of weeks, but again it depends on the above factors and the lasting time of our artificial grass pet odor neutralizer can vary.
