So I bought a blacklight at the pet store today to try and locate all the urine stains in the house so I can begin the cleanup process while re-training my cat to use his litterbox. Well...I almost died when I saw how many stains there were. It looked like a glowing massacre in my dining room. So Ive already used a whole gallon of solution that I bought today, but I was wondering, how do you know if you've affectively cleaned the pee? Will it disappear from view when the blacklight is used again after it has dried? Or will there always be a stain there? Just curious because even after all the spraying and scrubbing, the stains all still look kinda the same under the blacklight..Just hoping im getting somewhere!
