There are two sources of odors associated with urine. The first comes from bacteria that grows abundantly in the dark warm places with a never ending food source.

A pet can feed the bacteria daily this bacteria growth and breakdown of the creates amino acids. These complex organic compounds will often work deep into the fibers to a point of becoming part of the fiber. This can present a challenging situation.

The second source of odor is chemical odor that is present source of odor that is present even when the bacteria have been killed. This explains the reason that more

than sanitizing is necessary to neutralize odors from urine.

URINE ALSO PRESENTS ADDITIONAL ODOR PROBLEMS WHEN THE RELATIVE HUMIDITY IS HIGH.

The salts and crystals that are left behind as the urine dries are hydrophilic and draw water to them. Dried urine is often easy to smell in the humid months because

the attract the moisture, the moisture evaporates putting out a greater proportion of odorous ammonia gas.

You must get rid of the urine salts in and under the carpet.

THAT'S WHY CLEANING EXISTING URINE SPOTS WILL NOT REMOVE ANY ASSOCIATED ODOR, IN FACT, IT COULD INCREASE THE ODOR IN THE AIR SPACE

FOR A TEMPORARY PERIOD OF TIME.
