Stains and Odor
Urine is made
up of several waste products of metabolism such as urea, cholesterol (lipids),
and uric acid. Another component, called
urochrome, gives urine the yellow color. The exact make up depends on the animal’s
diet, health, age, and other factors. When
urine leaves the body, it comes in contact with bacteria in the urethra, the
animal’s skin, and microorganisms in the carpet. The warm acid environment is the perfect
breeding ground for bacteria, which begin to flourish. The bacteria give off gasses, which is one
component of the odor we smell.
As the urine decomposes, it changes in pH from an acid to an alkali. Alkaline
salt crystals from when the acidic urine reacts with the ammonia being created.
These hygroscopic salts draw moisture
from the air and remain slightly moist and chemically active. As long as it remains active, it will produce
ammonia gasses. Dried urine salts will
give off more ammonia gas once re-moistened, which is why the odor is stronger
on humid days or after cleanings.
Bleaching
Pet urine
stains can have a permanent bleaching effect on some types of carpet depending
on how they are dyed. Over time, as
urine sits in your carpet, it becomes highly alkaline, and can bleach out
primary carpet dyes until you are left with a yellowish or white
discoloration. Bleaching may not become
apparent until the carpet is cleaned, at which point the carpet dyes previously
released by the pet urine are removed, and suddenly a light spot appears. At that point, the only option to repair the
damage is to re-dye the spot or patch the carpet.
It’s Not Just On the Carpet
Although a
pet stain may look small on the surface, it can be 2-3 times the size
underneath. Just a few ounces of urine
can quickly soak deep into the carpet backing, the padding, and even the sub-floor
below. Urine odors can permeate from the
floor, be it cement or wood, from the tack strip, and even from the framework
of the house behind the walls. Cleaning
the area as soon as possible will help prevent the urine from soaking through
to the backing and pad below and avoid permanent bleaching.
Besides the
obvious health and sanitary issues left untreated, urine causes difficult to
remove yellow stains, or worse yet, dye loss. The amount of time that these components
remain in the carpet fibers has a great deal to do with the success rate of
completely removing both the spots and the odor, and prevent bleaching or other
damaging effects.

enzyme treatment can help remove stains and odor from carpet and upholstery. We also offer more extreme measures for old
urine stains that have affected the subfloor, baseboards, or other areas of
your home. Call or go online to learn
