You could certainly try my method but I’m not sure how effective it would be after steam cleaning. However, the black light would definitely help in identifying an individual area you could treat and see how successful it was.
Citrus fruits contain enzymes that help break down odors. You can make a powerful enzymatic cleaner that removes most pet odors, but you need to be patient. These solutions have to brew for a few months.
Most cleaners and odor removers work their best if you attack the problem as soon as it happens. The quicker you get to the disaster the better off you’ll be. Enzymatic solutions are particularly useful this way since fresher material will find the material more “palatable” in the immediate aftermath.
If not treated properly, the odor from pet accidents can travel through the entire home and impact your health and your happiness. The smell emitted from an accident area also often leads to repeat incidents in the same area until it is properly eliminated.

CR’s take: The Rug Doctor Mighty Pro X3 has front-to-back sliding brushes instead of rotational brushes, like other carpet cleaners, similar to the commercial version of the Rug Doctor you can rent. It’s relatively heavy at 43 pounds and takes 3 gallons of water to fill its tank—easily adding up to 25 pounds to its weight—and wasn’t very intuitive when our testers went to fill it up. It does have a long hose, at 155 inches, so you won’t have to lug it at every turn, and its dryness score is Excellent. But unless you have a lot of carpet to clean and plan to clean often, you might want to consider a lighter model. 
The only possible case when you can use the iodine to remove the urine smell is the case when you have a dark carpet. Prepare weak solution of the iodine (15 drops of iodine should be diluted in 1 liter of water). The diluted iodine is applied on the spot for 5-7 minutes. After that you should rinse the carpet with the textile soaked in warm water.

Not only is it difficult to deal with a pet urine accident once one has occurred, but it’s also tough to know where past accidents may have taken place, including accidents you may not have even known about. Using a special UV light, Chem-Dry can detect pet accidents in your home and eliminate pet urine odors from your carpets, rugs and upholstery through our revolutionary cleaning process called P.U.R.T.® (Pet Urine Removal Treatment).  P.U.R.T. contacts the source of the odor and immediately begins a chemical reaction that destroys the pet urine odor. It’s shown excellent results on even the most severe pet urine damage.
Hydrogen peroxide is another great substance when it comes to breaking down the “crystals” of urine and pulling out stains. Combine it with naturally deodorizing baking soda, and you have another great solution for cleaning up stains.
While it’s not a standalone product, if you’ve invested in a carpet cleaner then you’re going to be quite happy with Bissell 2X Pet Stain & Odor remover. It’s also a lot cheaper than most standalone options.
Pets are great, but they don’t always smell that way. Even the cutest cats and dogs can make your rugs and furniture stinky if you’re not vigilant. Worse, even the best pets can have accidents on the rug.
For linens, blankets and cushion covers, add a ¼ cup of apple cider vinegar to any oxy-powered detergent powder, such as boric acid, and launder as usual. Also, leaving a deep glass dish of white vinegar standing in a room with an offensive odor usually takes the odor out of the air.
Sophia: I really need to do something about this problem in the house we just moved into 3 weeks ago. Before we moved into this house we had the entire carpet professionally steam cleaned. The carpet cleaner could smell dog urine as soon as he came into the house (it was a rainy day). It has been three weeks and we still smell it in a couple of the rooms.
I used to run 3 subsidised housing complexes. Got tired of tenant after tenant getting charged for the same damages… So I got my carpet guy to teach me how to remove 99% of all stains and odors. This is a slow process, but very effective. Take a used steam iron… fill with water and heat. Get a white towel. ONLY a white towel. Dyed towels may bleed colors. Soak white towel to drippy wet. Use clean water or your favorite cleaner. Put the dripping towel over the stain/odor. Sit the hot iron on the wet towel. Watch carefully for the grunge to show on the towel. Keep rinsing out the towel. Keep putting steam iron on towel over damaged spot. Rinse iron and towel as needed. Repeat until no scent or stains appear. DO NOT LEAVE UNATTENDED. If so you may burn or damge carpet. I have gotten blood, urine, kool aid, wine and ink out this way…. many many times. Didnt work on mustard.
Add a one-pound box of baking soda to your regular detergent and wash as usual, air-drying if possible. If you can still see or smell the soiling, wash again with an enzymatic cleaner — these break down pet-waste odors.
I purchased this product last year, and it really does do a nice job at removing the odor from the cat urine. I have wood floors, and I’ve used it plenty of times directly on the wood floor with no negative consequences to the wood.
In every second house people have their favorite pet and all of them from time to time cause problems which smell. Usually pets have a tray or they wait patiently when they will go for a walk. It happens quite often that the pet does not want to wait and behaves inappropriately: for some reason pees exactly on our new favorite carpet which we bought just recently or even received as a present from our grandmother. Anyone who was trying to get rid of pee smell and succeeded is getting pissed every time it is happening again. We will investigate best and simplest ways which remove urine properly.
Our dog is potty trained. But now, she is peeing in the hallway, dining room and master bedroom now. We’ve been using baby gates to keep her from going in that part of the house. But we’re getting frustrated with having to climb over baby gates now. What can we do or use to get her to stop peeing in these areas of our home?
If the vinegar mixture is not working, you need to have a professional come out to clean. The problem is not the carpet, it is the padding underneath the carpet. If a spill or accident is not blotted up immediately, it soaks through the carpet and into the pad. When you spot clean, it does not clean down to the pad. The carpet may smell nice & look good, but if it gets wet or warm enough then the stuff left in the pad will come back up into the carpet. You really need to call a professional carpet cleaner with a truck mounted unit to come clean it. Their systems use very hot water & have a strong suction unit. They can get deep down to the pad & then extract all that water so it does not deteriorate the backing on your carpet.
Did you know that cats are obligate carnivores? This means that hey HAVE to eat meat, ONLY meat. They do not need vegetables nor grains. Veterinarians sell foods with grains without even considering the physiology of felines, it’s absolutely horrible. Cat food manufacturers show pictures of healthy vegetables and grains on the bags of food and people think it’s good for their cats, it’s not. I’m convinced that this bad diet, perpetuated by nearly everyone, is the cause of so many feline problems…UTIs, bladder issues, diabetes, etc.
Add a bit of bleach into the water (ratio of 1:10) and stir it. Apply the resulting mixture on the spot where your dog left some pee. In 20 minutes wash the whole surface or even the whole carpet with the water.
Most people will have bad breath at least once in their life, but it is unusual for breath to smell like urine. Possible causes range from nasal congestion to chronic kidney disease (CKD). Treatment depends on the underlying cause. Here, learn more about why breath might smell like urine and how to treat it.
Open windows. There’s nothing like some nice, fresh breeze to air out bad smells. In spring, summer, and fall, open windows throughout the house to create a breeze that will blow fresh air in one window and bad smells out the other.[9]
I was ready to change a brand new carpet Due to the urine smell. The whole house smelt because of that room. I did the whole process and the results were amazing. Fresh smell not even a bit of urine smell. Read all Testimonials
It may not be the biggest name in the business, but Rug Doctor presents this pretty awesome cleaner with a great included shampoo to handle pet messes. The main draw here, however, is definitely the huge amount of suction you’ll be getting out of it.
Mix a solution of fifty percent white vinegar and fifty percent water. Use a spray bottle to apply the vinegar solution to the carpet. Work the solution into the carpet with a soft brush (or your fingers) to ensure it penetrates the carpet fibers below.
Carpet is just not designed to be washable to the degree required to get urine out, if its soaked through the underlay and into the floor below then you have pretty much no chance at all and really you need a new carpet or better yet… a waterproof flooring like lino or tiles.
