How to use the UV black light to find urine?
First, darken the room as much as possible the darker the room, the easier it will be to detect the dried urine. Dried urine has a characteristic dull yellow fluorescence or glow. This will help you to distinguish it from other compounds that may also glow. With the Consumer model (or mini Black Light), the output is not so bright as to cause a problem in ordinary use, though caution should be exercised in never looking directly into the light. Features: • Mini Black Light Kit. Includes 1 specially designed black light. • One 500 ml bottle of Urine Stain Remover. • Light requires 4 AA batteries. Multi-Purpose Urine Stain Remover Spray Urine Off (1 Liter Spray Bottle) can be purchased seperately.
