Pet urine can cause permanent damage to your floors and fabrics.
It can also create an unhealthy indoor environment. When urine is first deposited onto a floor or
fabric, it has a pH of about 5 or 6, which is on the acid side of the pH Scale
and is easier to remove when it is fresh. Once it dries it turns alkaline or
to a high pH between 10 to12 on the scale and becomes more difficult to remove.
The warm acid state of the urine offers a perfect breeding ground for bacteria,
which begin to flourish almost immediately.
In this original acid state the urine begins to oxidize and react with the carpet to
create a color change, which will become permanent if the urine is not removed
immediately. Some of this color change can be attributed to the
strong ammonia that forms as the urine passes through bacteria and chemical
change. If left for days or weeks, depending on the fabric
or floor type, it will change the dye structure,therefore causing permanent staining.
Even if the soluble deposits are removed, the damage
to the dye structure may already be done.
There are two sources of odors associated with urine. The first comes from bacteria
that grow abundantly in dark warm places with a never-ending food source. A pet
can feed the bacteria daily! This bacteria growth and breakdown of the urine
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 waste materials and gases from the decomposing urine
create an unpleasant odor. When dried urine is remoistened, it gives off an
ammonia gas. If smelled once it is seldom forgotten.
The second source of odor is chemical 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 salts 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 to get rid of the odor.
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.
