I just purchased your product for Pet Oder–along with the battery operated Black Light. Although I can smell the cat’s urine oder from previous wettings, I do not see thenm with the black light.
What am I doing wrong? Steve Y

No you are not doing anything wrong Steve, you are looking at History. As It is true the black will reveal were you concern lye, Pet friendly or any product for that matter can’t remove that history. So when you see what was, understand that that will always be. History! Less the smell. Hope that explains it.
