I've spent hundreds of dollars on all types cleaners; I've even tried the home remedy of baking soda and hydrogen peroxide (I don't recommend, it bleached my carpet) While I doubt there is any cleaner out there that will make your carpets black light clean, this comes in a close second. Soak of the mess as much as possible, then spray this cleaner on it and forget it. No scrubbing or anything. The down side is its on the expensive side and you go through a lot of product to really soak the pee spot. (I use the full stream spray)
I bought this product directly from their website.... It was cheaper.
