Dogs and cats make great family pets and today have become cherished family members. While most dogs and cats are very conscientious and rarely make a mess in the house, there are times when accidents occur and there are some pets who are chronic offenders.
A pet stain is simply a biological stain from urine, vomit, poop or even drool. Areas where vomit or poop occurs are easy to spot, but urine stains can be particularly difficult to find because you usually cannot see them after they dry. Frequently, the only way that you know about a urine stain occurrence is when your nose detects the pungent smell.
Fortunately, there is an easy way to detect areas where urine stains have occurred. Biological stains on carpet or furniture upholstery will glow under ultraviolet (UV) light, which is also known as blacklight. This phenomenon is known as fluorescence.
The best ways to detect these stains is with an ultraviolet LED flashlight or cap light. The room must be completely dark. If you are using a UV flashlight, stand in the center of the room as scan all around the room. With a UV cap light, get closer to the floor or furniture and scan it with a sweeping motion. Then check all corners and behind furniture. Biological stains will look white and will stand out in the darkened room.
If you find biological stains, identify each with a small piece of paper (Post-Its work great) or a small object so that you can find them after the lights have been turned on. You can remove biological stains using any of several pet stain removal products. White vinegar and water also works well. Pour the vinegar directly on the stain and flush it with water. Soak up the wet spot using towels. White vinegar works particularly well for neutralizing pet stain odors. After the areas have dried, check them one again with the blacklight flashlight or cap light in a dark room.
Blacklight cap lights are typically used in conjunction with fluorescent lures and fishing line for night fishing. They are also used for scorpion hunting and thus server multiple useful purposes.
