Using a dog urine detector to locate stains

Not only will past urine stains make your home smell bad, but your dog may also feel the need to continue marking over the previous stain.

No matter how many times you clean the area, if you don't get the entire stain, your dog will still be able to smell the urine.

It would be a shame to throw away money for frequent carpet steam cleaning simply because you can't pinpoint the exact area where the mess occurred.

Black lights have long been used for various functions, including law enforcement, postal inspection, and HVAC repair.

And pet owners have recently joined black light patrons as they get more involved in managing their pet’s training, hygiene, and overall care.

Wondering why dog urine will show up under a black light? According to ThoughtCo.:

Urine glows under a black light primarily because it contains the element phosphorus. Phosphorus glows yellowish green in the presence of oxygen, with or without black light, but the light imparts additional energy that make the chemiluminescence easier to see.

For this reason, the best dog urine detector will utilize UV technology to help you find the exact shape of a dog urine stain.

By scanning the area, you are sure to clean all of the urine.

And once the spot is dry, you can check it again to ensure you've gotten all of it.
