Odors in Carpeting
Urine odor in carpeting is a bigger problem than just the urine you can see. The carpet's nap and backing act as a sponge, taking the urine away from the top layer, being absorbed into the padding, and often the floor under the
padding (wood, laminate, concrete, etc.).
The padding becomes a holder of urine, making the amount of urine on the back of the carpet which you can't see bigger than the urine on top of the carpet that you can see.
because most padding is made of a composite sponge material that can hold a
large volume of liquid. As the liquid slowly evaporates (though the carpet) and
spreads into an ever widening circle in the padding, the urine residue (mostly
urea salt) deposits and accumulates in the padding. Repeated applications of
urine result in more concentrated deposits and larger areas of residue.
padding becomes saturated with liquid in an area, the liquid soaks into the
flooring under the padding which allows the carpet above to stay wet for a much
longer time and produce much more odor. This is why a urine contamination
problem can go undetected for weeks or months and then all at once become a big
If you have and Oriental carpet with an odor problem, check out the Oriental Carpet page. If you have mold in carpeting check out the Mold In Carpeting page.
To get the odor out and have your animals stop peeing in that area, first:
- Determine if the carpet is worth saving. (It will take some elbow grease to get this job done) If not, throw the carpet and padding out and spray OdorXit Concentrate on the flooring below. COMPLETELY GET RID OF THE ODOR BEFORE LAYING NEW CARPET.
- If the carpet is worth the trouble, find the areas where the urine is located
- You can do this by shining most UV lights at your carpet. If urine is there, most urine will fluoresce under the UV/black light. This is were to apply the OdorXit Concentrate solution.
- If the urine is still wet, use a wet-dry vacuum to remove as much of the urine as possible. Pour a glass of water on the urine to moisten dried urine, vacuuming out as must as possible of the urine.
- Mix 4 ounces of OdorXit Concentrate to one gallon of water.
- Pour the solution slowly on different parts of the urine spots on the carpet and rub it with your hand to allow the solution to soak in deeper.
- Don't saturate the carpet. Pour just enough solution to get to all of the urine.
- Let the solution dry in the carpet. There's no need to vacuum it up if the carpet isn't saturated. It will neutralize the urine and the animal won't smell any urine and won't use the same area to urinate again.
- If urine is in the corners of the room (where cats usually urinate), pull the carpet back and spray the backing of the carpet.
- Depending on how successful you want to be, pull the carpet back to treat the flooring below. Yes, even it the spots are in the middle of the floor (which is usually where dogs urinate). You must get the OdorXit Concentrate solution to ALL the urine to neutralize ALL the odor.
- Sometimes, the padding can't be saved even if the carpet can. Padding is foam and glue and will not allow the OdorXit access to all the urine. Plus it is really inexpensive. So cut out those areas of the padding and replace with new padding.
- Spray the floor beneath while you have the carpet and padding pulled up. All layers need to be sprayed with OdorXit Concentrate Solution.
- Then stretch and tack your carpet back in place.
- Urine contamination of carpet will eventually weaken and
destroy the carpet backing. Regardless of how effective OdorXit is at
eliminating organic odors, it will not restore rotted carpet backing to its
former condition. I.E., there is a point of no return for contaminated carpet.
This point is often punctuated by the carpet splitting as it is being reset on
the tack strip, or as a piece of furniture is moved across the room.
like padding, can also become so loaded with contaminate that it will simply
overwhelm OdorXit's ability to neutralize the urea salt stored in the carpet. This
situation is usually reserved for folks who are rehabbing real estate and home buyers
that notice an odor when initially inspecting a house. Please refer to the
on this site for a pictorial example of what can happen.
Recovering contaminated carpet padding
Because of its ability to hold liquid like a
sponge, home carpet padding is almost never completely recoverable.
The amount of concentrated contamination, the physical makeup of the foam,
and the relatively low cost of replacement padding, make even attempting
recovery a loosing proposition. The cost of the OdorXit aside, your time
is more valuable than the cost to replace the padding including labor!
Because padding is relatively inexpensive and easy to handle, we recommend
that you cut out the contaminated padding and replace it with new after
the odor problem is resolved. Spray both the
and the back of the carpet and give the OdorXit overnight to work.
Recovering contaminated Car padding
Car padding is very often recoverable because it is made of an entirely
different material, not foam. Additionally, the number of times urine is applied
to the carpet and padding in a car is generally very low. But remember, the OdorXit
solution must come in direct contact with the contamination in the carpet, padding and
flooring. Mixing carpet cleaner containing surfactant will make this process
much easier since it reduces the surface tension of the water, making it wick into
the carpet and padding much faster and completely.
Cat Scent Marking On Carpet
Cat scent marking spray on carpet is a problem that
is detectable right away because it is not necessary for it to accumulate like
urine to become a problem. Except for the urine portion of
the marking, it does not soak through the carpet like urine It generally
lays on top of the nap and on the wall. Treating spray is addressed on the
Pet Hormonal Spray Page.
Dog Urine Contamination
When you consider that a 30 pound dog can urinate 1/2
cup of urine per incident, and one incident is rarely the case, the amount
of diluted OdorXit needed could be 1/2 to 1 gallon for an area 2 feet in
Dogs nearly always use the center of the room or a door way to relieve themselves.
This makes accessing the padding more difficult. But remember that the
OdorXit solution must come in direct contact with the odor producing sources in
the carpet and flooring even after you remove the padding.
padding in place and treating just the carpet will
often reduce the odor to a tolerable level but will almost never eliminate
all of the odor. Further, if the padding is wet (like it is most of the
time) it will stay wet for at least weeks, and sometimes months, damaging
both carpeting and flooring.
Cat Urine Contamination
When cats have contaminated a carpet, it is often along the wall and in the
This being the case, the carpet, padding and flooring are not the
only elements involved. As an example, when wall to wall carpeting is
involved, there is a wooden tack
strip that is nailed to the floor and has tacks sticking up to
hold the carpet in place. Urine will stain the wood and rust the tacks
as pictured. Notice that the urine stained the bottom of the tack strip as
In a case like this, replace the contaminated tack strip.
Another area that can be involved is the 2 by 4 that lays along the bottom of the
wall. Urine will seep along the flooring or sub-flooring and under this piece of
wood. Whenever the humidity goes up, it will smell bad! Again, the OdorXit
solution must go wherever the urine went in order to stop the odor...Doing this WILL stop the odor. Forever.
Carpet Recovery Procedure
On carpeting that is heavily contaminated with urine, OdorXit Concentrate
is far from 100% effective. However, for superficially
contaminated carpet you can start your carpet recovery
effort with a carpet cleaning machine to remove most of the urine contamination
and then apply OdorXit in combination with the carpet shampoo (2-3 ounces of
OdorXit per gallon)with a sprayer. There are many benefits to this method of
- The carpet gets cleaned,
- Much of whatever else was used previously to eliminate the odor
is removed, and
- The wetting additive in the shampoo helps the OdorXit penetrate deeply into the carpet nap and backing.
- The OdorXit solution is not removed by the carpet cleaning machine.
Most upright carpet cleaning machines will do the job.
We have used the
Hoover Steam Vac
home unit and it works well, but it costs well over $200. We have
not used the new
carpet cleaner or the
Bissell carpet cleaners,
but they seems to have the right stuff. Renting a cleaning machine is
a good alternative. Ask for the up-right units that have agitators or
beater bars. If the up-right units are not available, the tank type will do,
but not as well.
All carpet cleaning machines will spray warm to hot solution of carpet
shampoo onto (into) the carpet and then retrieve the excess solution and
much of the dirt from the carpet. This is just what is needed for
carpet contamination that has not gotten completely out of hand
and ruined the carpet. The Hoover carpet cleaning shampoo have surfactant additives
that are left in the carpet after the cleaning machines
agitator has worked it into the carpet. This residual surfactant helps the OdorXit
to penetrate much more deeply into the carpet than it would without the shampoo.
If the carpet seems to be clean but the urine odor persists, the odor
is probably coming from the padding and flooring under the carpet or
from spray/urine on the adjacent wall. Heavily contaminated carpet
will almost always have to be replaced to achieve 100% odor removal..
Recovering Tack Stripping
Often, some or all the tack strip will need to be replaced because
the urine on the tacks rust and weaken them very quickly. Additionally, the
urine gets under the tack strip and travels a long way (sometimes several feet).
OdorXit must get to this contaminate to remove all of the odor.
Urine Contamination Under Walls
When there is urine contamination near a wall as
in the tack strip situation described above, it is very likely that the urine went under
the wall as well. Spraying OdorXit directly under the base board and drywall
will usually result in enough volume of OdorXit to get to the same area
the urine went. Drilling small holes through the drywall and wall plate
and then injecting OdorXit will sometimes be necessary.
Testing For Urine
When it appears that the odor is completely gone, spray a mist of plain
water everywhere you had urine contamination and wait several minutes. If
you smell no urine odor, you are finished with the odor elimination phase. Now
you can tape the new padding in place and reset or have the
carpet reset on the tack strips.
Do not expect one of these household type carpet cleaners to restore badly
soiled carpet to new condition. They are not capable of doing the same job that
the professional machines can do, but are excellent for cleaning the carpet and
getting the majority of the dirt prior to applying OdorXit. If the carpet is odor free and still not clean
enough, call in the pros and have it cleaned again. The professional cleaning
will not effect the action of the OdorXit because it has already done all its
going to do to the odor causing contaminants in the carpet.
Cleaning Carpeting Removes Dirt and Stain Repellents
As a result of cleaning you're
carpets, all or most of the dirt and stain repellent has been removed. This
will cause your carpet to get dirty much faster than before. Re-applying Scotchguard
or similar replacement can restore the dirt repellent action to nearly new levels
assuming that it is applied in sufficient quantity to do the job. Just spraying a can
of Scotchguard on the room sized carpet is not sufficient quantity.
In all cases, it is
very important that some
OdorXit solution come in direct contact with all of the odor causing
agents. If the OdorXit solution dries before it soaks into all the
contaminated area, the odor will not be completely eliminated.
