Why is Pet Urine so Difficult to Clean?
Urine has many components that can be washed away with ordinary cleaners, but it is the insoluble urine (uric acid) crystals that are the source of most of urine’s stain and odour. These crystals cling to any carpet and rug fibres, including smooth, hard surfaces like tile and porcelain. Many household chemicals like bleach and cheap store chemicals can’t remove them effectively.
Many products on the market attempt to mask the urine odour with another deodorising chemical, or seal in the urine. Other products dry out the urine salt crystal with alcohol or solvents. These are short-term solutions only and leave the insoluble urine salt crystals in the carpet. If you ever tried such products and thought they worked, only to have the urine smell return when the product wears off or when high humidity re activates the crystals?
