First of all, common sense is needed when detecting damage from urine. A black light is a good tool to figure out where to start looking for damage and carpet stains but is in no way a sure sign that urine is present. Dog and cat pee will fluoresce or glow under a black light. A typical black light urine mapping is where the lights are turned off, shades are shut and the carpet cleaner will do a tour of the carpet. This can be very useful information, but it is not complete. A map made from black-light data only can be misused information because although urine will fluoresce, so will many other substances including:
- Woolite Carpet Cleaning Products
- Baby Powder
- Tonic Water
- Most Laundry Detergents
- Petroleum Jelly
- And Many More
However, you would be amazed how many carpet stains show under a black light that the naked eye cannot see. Watch this video to see just how many stains there are in your carpet the last carpet cleaner left!
