Review on 🔦 Powerful 395nm UV Flashlight: Easily Spot Cat/Dog Urine, Pet Stains, and Bed Bugs - Includes Pet Odor Eliminator [Batteries Included] by Shannon Myers

Used fluorescent paint to find a leak in my car's engine compartment. Works great, light intensity is good and the dye was visible even in full daylight. This is not a magic organic detector. Bright white things will shine in a dark room. Thus, salt crystals from dried bodily fluids may, but most likely not, be visible. Maybe your pet's dried urine. Possibly dried sweat. blood, no. Ejaculate, maybe when fresh. The glow in the toilet is the salt of the tap water, not the lack of cleaning. Well, now I've spared you embarrassing questions based on fake television science. Get one of these lights now, they are useful and fun!
