Review on 🔦 LE Black Light Flashlight - Small UV Lights 395nm - Portable Ultraviolet Light Detector for Invisible Ink Pens, Dog and Cat Pet Urine Stain - Includes AAA Batteries by Eric Nallamothu

Works for dog pee. I could smell it but didn't see it. I was a bit hesitant due to some reviews saying it doesn't work with dog urine. I'm here to say yes it is! I'll share what I did to get the best results. Thanks to the amazing camera on my Samsung and a little light correction you can really see how it stands out. I did this on purpose because just using a phone camera UV light smudges photos and they don't render it properly. I haven't seen anyone post a photo of dog pee yet so here it is. It must be dark. As dark as it gets. Do it at night if you can.2. First vacuum the carpet well and then rake it lightly so that the fibers run in the same direction. Save the supplied batteries for a remote control or the like. You can't expect much from a battery in this price range. The first use must be with a well-known brand AAA battery. Wipe the lens with a clean soft cloth and viola! Pi!
