How to Use Your UV Black Light to Detect Cat Urine
Though many cats are litter box trained, their urine can sometimes end up outside the box. It is not unusual for cats to spray (especially if they are not neutered), and for cats who are older or suffer from anxiety to urinate on the floor or furniture. Cat urine is known to have a distinct unpleasant odor, but it is not always easy to see or find when you are trying to clean it.
We have good news, though. By using a UV black light, you can easily locate cat urine stains and keep your home clean and odor free. There are a variety of different UV flashlights, so you will want to make sure to select the right one. Many UV lights emit a wavelength of 390 nm to 400 nm, allowing you to detect dog urine and common household stains. For cat urine, however, it is best to use a light in the 365 nm to 385 nm range. These UV lights tend to be more expensive. Luckily, our affordable and high-quality GearLight S50 UV Black Light Flashlight produces 365 nm, making it the perfect light for detecting cat urine!
Follow these steps to find and remove those pesky stains:
- Grab your GearLight S50 UV Black Light Flashlight - With a wavelength of 365 nm, the S50 detects cat urine stains not otherwise visible to the naked eye on carpets, floors, or furniture. The ultraviolet light emitted from this black light allows urine stains to glow, revealing the exact source of odor.
- Wait until the urine has dried - UV lights only produce a glow when cat urine is completely dry. If the urine is still wet or there is any humidity in the room that is causing the affected surface to absorb moisture, there will likely be no glow. Once the urine and area are dry, you can start your search.
- Make sure the room is dark - Your UV light will be most effective in dark conditions. We recommend waiting until evening time and turning off the lights. If the room is too bright, your UV light may produce little to no glow.
- Shine your black light - Try to find the exact location of the odor, and shine your light at it. If there is in fact cat urine in that area, it will fluoresce as a pale yellow color with a possible faint light green tinge. It may take some trial and error for you to detect the urine, so search around with your UV light until you see a glow that is this color. Cat urine can present itself in a number of ways depending on whether the cat has sprayed or urinated. The stain may look like a spot, pool-shaped puddle, drips, or a splatter, and may be on the floor, furniture, or walls. Keep in mind that if you see any bright white glows, those are caused by other substances such as carpet cleaners, drink spills, and wallpaper glue.
- Mark the stain - Place some sort of marker (e.g., tape, pencil, chalk) around the stains. This will help you easily locate the stained areas once you turn the lights on.
Now that you have identified exactly where the stains are, you can start the cleaning process. You will see that by using the GearLight S50 to point out the source of the mess, your cleaning time will be a fraction of what it was before!
