Pet urine is one of the most damaging things that can come in contact with carpet. Not only is it acidic which allows certain fiber types to become stained, it can destabilize dyes, break down glues and backing subject to the amount of exposure. Depending on the size of the spot and how much dwell time was involved, it is not uncommon for urine to migrate beyond the backing and into the padding. Standard hot water extraction cleaning involves removing contaminants from only the face fibers of carpet and has no deodorizing properties on its own. Once the urine has affected the backing and/or padding, this requires a more extensive cleaning process that involves these steps:
1. Use of a UV light to illuminate the areas of urine contamination. Urine contains phosphorus and broken down blood proteins which show up under a black light.Due to the influx of polyester based carpet fibers in the market today along with our love of dogs, many people are having issues with dog odor in carpet. These oil loving fibers make it a challenge to remove dog body oil from the carpet through standard cleaning. Bacteria builds up on the skin and is transferred to the carpet through the oil, leaving a “doggy” smell behind. Our process rinses the fiber free of dirt, which exposes the odor containing oil on the carpet fibers. This is addressed as follows:
1. Prior to cleaning, we pre-treat the face fibers of the carpet with an oxidizing solution and allow it to dwell.Urine is a complex organic chemical mixture containing primarily phosphocreatine – a chemical containing phosphorous – as well as urea and creatinine. After the urine is deposited and biological breakdown begins, these chemicals create ammonia and other nitrogen-based compounds that deliver the
strong smell associated with urine. Our process eliminates all three compounds and removes the odors generated as well as the pigments excreted with the urine. However, an area treated may still glow when observed under a black light, This glow is not due to the presence of urine in that spot, but from phosphorous left over from the breakdown of phosphocreatine. During that process the phosphorous becomes chemically bonded to the fibers as a dye would, and is thus very strongly attached to the fibers. Under a UV light, the phosphorous glows. But because the phosphorous is now part of the surface of the fibers, it is quite difficult to remove it without damaging the existing dyes on those fibers. Fortunately, there is little need to remove the phosphorus. We have fundamentally altered the chemistry of the original urine deposit so that no urine odors can be produced. Think of it this way: phosphorous is used in LEDs and fluorescent light bulbs to cause them to glow and produce light. And we all know that there is no urine in LEDs or in fluorescent light bulbs!

This is a service we provide to our customers free of charge. We know that many times urine spots go undetected by the naked eye and customers have difficulty pinpointing where the odor is coming from. Homeowners often have no idea whether we are going to encounter one spot or several in a home where pets have full run of the house. It is actually better for us to know prior to cleaning so that we can treat the areas appropriately and decontaminate them. Otherwise, we will encounter the odor later once the areas are exposed to moisture and heat.
