I also got a black light a little while ago because our little Sprite was peeing on my wool area carpet and I was grossed out at all the spots I saw
We just removed all the wall to wall carpeting and replaced it with hardwood last week because of my allergies, but I'm also relieved that Sprite can't leave any hidden surprises anymore. I went to the Nature's Miracle website and read their Q&A section. They say that after treating carpets with their product, the stains will still show under black light, but instead of glowing a greenish color they will appear more white. Apparently it is impossible to permanently hide the stains from a black light, but the urine itself will be removed with treatment. Think of it like a stain on your clothing. You wash it and the dirt is removed, but sometimes the stain is permanent, even though the clothes are clean. Those black lights sure are traumatic aren't they
