Why I Use a UV Flashlight for Pet Stains

Safety Features I Prefer
I always pay attention to safety. I avoid shining the UV light directly into my eyes or my pet’s eyes. I also like flashlights that have simple controls, so I can use them easily without fumbling in the dark.
Indoor and Outdoor Use
I like a UV flashlight that works both inside and outside. Indoors, I use it for carpets, bedding, and furniture. Outdoors, I may use it to check patios, garages, or yard areas where my pet has had accidents.
