Pet Stains On Carpets

What Can I Do Myself, Before Calling A Professional?

cropAccording to the American Pet Association, people in the United States provide homes to more than 130,000,000 pets. When left alone, pet urine can seep through carpet, into the padding and down to the floor beneath. Pet urine can delaminate a carpet and can cause rotting of jute backing. Even after a thorough cleaning, pet urine stains and odors often remain.

Pet urine is an amber-colored liquid waste fluid excreted by the kidneys and is composed of waste products of protein metabolism. The color of pet urine and its staining potential will often depend on dietary habits, age and sex of the pet, whether the pet is on medication, and the health of the pet.

Unlike dogs, cats do not urinate for territorialism. This behavioral pattern in male cats is accomplished by spraying primarily on vertical surfaces.  Although spraying is typically done on a vertical surface (such as a couch and the walls), it could also conceivably come in contact with a carpet.  Typically, because cat diets are richer in protein than dog diets, their urine will produce harsher odors and are more likely to cause stains.  In almost all cases, cat urine is the worst perpetrator for pet urine stains and pet urine odors.

Another consideration is the age of the pet. The older the pet, the more renal function diminishes, thus producing urine that contains more plasma proteins. Because less uric acephalia is secreted in this urine, it is less likely to stain a carpet; however, it will produce an even stronger odor.

How to Locate Pet Urine Stains With a Black Lightbkgd_odor

You can smell it…you know it’s there somewhere, but WHERE?

Step 1

Use your nose to locate sources of urine odor.  Although fresh urine stains should be easier to find due to their smell and wetness, you still need a black light to find older stains.Pet-Urine-Black-Light-Inspection

Step 2

Turn off all lights. It’s best to use your black light when the room is as dark as possible. Shine the black light on the area where you think there are pet urine stains.  Make sure to check around baseboards and even a few inches or more off the carpeted surface on walls and other vertical surfaces, as some animals may spray urine horizontally.

Step 3

Locate the urine stains. Due to the black light, the stains should resemble a green or yellow glow. Once you find areas that are stained, place a paper towel on those areas to help locate the stains with the lights on in order to clean them.

Tips & Warnings


  • Urine is NOT bright white under a blacklight.  Any stain that appears bright white is typically another substance such as a carpet cleaner or a spilled drink.  The residue from these substances fluoresces brightly under a blacklight.
  • Cats are rather sly animals and can maneuver into the smallest of spaces. Take your time and be thorough when checking your house.
  • Locating the source of the animal urine smell is vital, and the earlier it’s found, the better.
  • Soaps and detergents should show up as bright white when using your black light. Try not to confuse the cleaners and the urine.

Pet urine odor has its own problem, namely gravity.  Not only does the carpet get saturated with urine, but as it soaks through the carpet, it also soaks through the carpet cushion or pad.  Pet urine stains on carpet should be removed as early as possible. Stains that have appeared within a couple of hours can often be cleaned with good success.  This can be accomplished by taking immediate action.  Blot up the urine immediately, then make a 50/50 solution of white vinegar and water.  Apply the solution with a spray bottle. After this, absorb the spot with clean white colorfast towels until it is as dry as possible.  Next, place a one-half inch thick weighted layer of colorfast (white) towels over the spot and let it sit overnight.  This final procedure must not be overlooked, since crystallized urine residues left in the carpet are capable of reproducing odors during the warmer more humid months.

Dried Urine Stains:

If the urine stain has dried repeat the above steps, adding detergent to the white vinegar, and water.


Have pets and embarrassing room odors?

dog_sorryOur pets are part of our family.  They add comfort and happiness to our lives, but even the smallest pets can cause a fowl smell and detract from your otherwise lovely home.  Anyone can mask obnoxious odors with a heavy fragrance, but professionals know that to really get rid of an offensive odor, you have to remove the source. You also have to know how to find the source and what method to use to remove it. Pet odors are not the same as cooking odors, or cigarette odors.  Odors should be eliminated when they first occur, because the longer the source of an odor remains on a surface, the harder it will be to remove.   Waiting too long requires professional cleaning services to eliminate these unpleasant odors.  A “putrid” smell in urine is an indication of bacterial growth.  For this reason it is highly advisable to treat the area with a germicide, which can be purchased at a pet store.

Even the best professional carpet cleaning services have not been able to solve the whole problem.  Odor is just one part of this dilemma.  Even if the odor is removed, the discoloration of the stain is still an unsightly reminder of the pet’s accident, and the darling creature usually has a favorite spot or two that repeatedly gets the deposits, truly saturating some areas, thus accelerating color loss.  Further, visually identifiable urine stained areas may not reveal the extent of the problem readily.  Carpet is better than “Bounty” for soaking up liquids.  Even when treated properly, carpet cleaners get complaints about the discoloration still present.  These discolorations either aren’t removed by traditional carpet cleaning, or if removed, they soon return.  The problem isn’t the odor nor the cleanliness of the spots but rather the discoloration of the area from the pet “accidents” or the chemicals used to try to remove the stain.  These chemicals (including Resolve, OxyClean, OxyFresh, Clorox, etc) exhaust color of the carpet during the cleaning process.

Be prepared: Urine can affect the dyes used in carpet. While not all deposits result in a permanent stain, the content of the urine, the dyes and finish used, and the time elapsed after the deposit, are important.  Some urine spots may be immediately noticeable, while others may take weeks or months for a reaction.

CAUTIONNOTE: We hesitate to recommend over-the-counter products as they can sometimes damage or discolor the carpet.  No matter what kind of cleaner you use, you would be well advised to try the cleaning agent on a small, non-visible patch of the surface before applying it to the urine accident.

Methods To Avoid:You should avoid using steam cleaners to clean urine odors from carpet or upholstery. The heat will permanently set the odor and the stain by bonding the protein into any man-made fibers.  Avoid using ammonia based products to clean urine.  One of the ingredients of urine is ammonia and your pet may well be encouraged to re-offend in the same area.


As a final note, if a cat is urinating outside of its litter box it is a good idea to have the vet take a look at the cat.  This behavior is not normal for a cat and it could mean the cat is suffering from a urinary tract infection or other illness. You need to rule that out FIRST before you move on to any behavioral issues.

Dog Urine Smell and Stain Remover


Baking Soda
White Vinegar
Liquid Dishwashing Detergent
3% Hydrogen Peroxide

Directions for Dog Urine Removal

dogurineodor1. If the area is still wet you should first attempt to absorb the dog urine. Leaving it there to dry out will only encourage bacterial growth which causes the smell. The best method is to place several layers of paper towel over the wet area and tread on it so as to soak up as much of the dog urine as you possibly can. You may have to repeat this several times until no more urine can be soaked up.

Sometimes dog urine accidents have already dried because you did not notice them previously. You can find dried urine spots on your carpet with the aid of a black light. The dog urine stains will fluoresce under the ultra violet light in a darkened room. Hand held black lights are quiet inexpensive usually costing between $15 – $25

2. The next step is to mix a solution of fifty percent white vinegar and fifty percent water. You must use a liberal amount of this solution to reach the carpet fibers deep down. Work the solution in with a scrubbing brush to ensure it penetrates the carpet fibers below. Now blot the area again using the paper towel method above. The vinegar will neutralize the ammonia in the dog urine. If you own a wet and dry vacuum extractor use that to remove excess moisture.

3. When cleaning a dry urine stain repeat the above steps, adding detergent to the white vinegar, and water.When the area has dried or almost dried sprinkle a good handful of baking soda over the soiled area. Mix half a cup of 3% hydrogen peroxide with a teaspoon of detergent. Ordinary liquid dishwashing detergent is quite suitable. Do not use caustic dishwasher detergent.CarpetCleaningTips

Put on a pair of rubber gloves and slowly pour the hydrogen peroxide and detergent mixture over the baking powder. Work the dissolving baking soda well into the carpet, first with your fingers and then with a scrubbing brush.

Allow the area to dry completely and then vacuum thoroughly.

Use only 3% Hydrogen Peroxide
Test your carpet for color fastness in an area that won’t show.
