Black Light & Cleaning | Homesteady
Urine is notorious for soaking into carpets and smelling up rooms--or entire houses--even after it has been cleaned. This is because urine stains are hard to see with the naked eye and therefore difficult to clean completely. These stains cannot hide from black light, however. Darkening a room and shining a black light will quickly highlight where urine remains, letting you know when the stain is really gone.
