Most changes in urine odor are not a sign of disease and go away in time. Some foods and medicines, including vitamins, may affect your urine’s odor. For example, eating asparagus causes a distinct urine odor.
3. The “hair trap” (a small red square “tray”) doesn’t work so well. Is it a big deal? I don’t know. It may be for some. It is a hassle to have to scoop hairs off the top of the bladder when you are going to reuse it right away rather than just emptying the little trap. Does it affect performance? It hasn’t so far that I know of. I know that it is more hassle to clean the tank with loose hair in the tank and stuck to the bladder. You have to watch it going down your drain so you aren’t dumping pet hair and carpet fuzzies down the drain. It just means that I have to lift the bladder that holds the soap/clean water and shift it when I rinse when I am cleaning it to put it away. I don’t know if that means it gets into any part of the machine’s motor or not though. Someone more technical than me can possibly answer that question.
Step 1: Create a vinegar cleaning solution consisting of one part white vinegar to one part water. Vinegar neutralizes the ammonia smell of urine without fading carpet fibers, making it a good choice for cleaning and protecting your carpet.
In addition to an ammonia-like odor, another telltale sign of dehydration is bubbles in a person’s urine. And if someone is dehydrated, their urine is dark honey or brown color, rather than a pale yellow or gold.
Slowly pour your solution onto the site and gently scrub with paper towels or a soft brush. Let sit for 15 minutes, then dust with baking soda. When it’s dry, vacuum. You might need to do this a few times for tough stains or especially strong odors.
Carpet cleaning machines are very powerful machines, but they can also take a beating. If you’re dealing specifically with pet problems on a frequent basis it’s better to buy a specialized machine than it is to keep spending a whole bunch of time cleaning your device.
What I like most about this product over all the others is it does not have an overwhelming scent that competes with the urine. Instead, it has a clean almost non-existent smell and really seems to get rid of King PeeALots odor. My nose couldn’t be happier and for now the tiny murder machine is confused as to why his carpet doesn’t smell like contempt anymore.
After applying vinegar to the pee spots and sucking it up with a wet vac…the spots where vinegar was applied shine bright yellow under black light. Does that mean the vinegar created a worse problem? Or that the pee is still there? Any ideas?
Try using a carpet shampooer. Fill the shampooer’s reservoir with water, and add the liquid cleaner to the compartment. Press the lever and vacuum the entire carpet. Allow the carpet to dry for at least 24 hours, and then vacuum.
I strongly advise that if you are contemplating the above instructions you stop. There are cleaners that can remove the stains and smell without you having to play laboratory and creating things that can ruin your home. My choice of cleaner for pet stains is Genesis 950. Cleans better then anything I have tried . . . and I have been through a lot of different products. But even if you don’t use that, use anything . . . just don’t do the vinegar/baking soda thing.
I​’m interested in the intersection between design and technology​—whether for ​drywall or robotic vacuums—and how the resulting combination affects consumers. I’ve written about consumer advocacy issues for publications like The Atlantic, PC Magazine, and Popular Science, and now I’m happy to be tackling the topic for CR.

Mix lemon juice (commercial or freshly squeezed) with water and sprinkle it on your carpets. This smell is pleasant for people, but will keep your dog at bay. The citric acid is also effective if you want to clean and remove urine odor from carpets.

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 quite inexpensive usually costing between $15 – $25.
There is also one trick which can helpful if you want to prevent repetition of the odor problem. If your dog is constantly peeing in the place you can sprinkle few drops of essential oil of apple, cinnamon or eucalyptus. This pleasant for human smell dogs do not like at all.
Vacuum up any loose debris from the area that will be treated. Wet the area to be treated with clean, warm water. Using your vacuum or carpet extractor wet extraction capabilities, clean the are 2-3 times, leaving the area damp. Pour OdorKlenz Pet Urine Eliminator on the treatment area. Spread the OdorKlenz Pet Urine Eliminator on the treatment area. Spread the OdorKlenz Pet Urine Eliminator into the area working it deeply into the carpet or covering surface completely.
Pink or red: Some foods like carrots, blackberries, beets, and rhubarb can turn your pee a pinkish-red color. This can also be a side effect of medications like the antibiotic rifampin or a drug for urinary tract infections (UTIs) called phenazopyridine. 
Be warned, you may want to not be as vocal as I was when I was so impressed with the results that this cleaner had produced. It cleaned so well that I told my ENTIRE extended family and now everyone wants to try (borrow) mine, grrrr…. I’m literally having to organize a schedule so I can get it back in time to clean our rugs as I want to clean them at least twice a month so they do not get as bad as they were EVER again! I told everyone that I want it to come back with a “FULL TANK” LOL *meaning I want a FULL container of cleaning solution when it finally gets back to me! 😉
I just moved into a new place, the people who lived in it before us had dogs. The pet urine smell is actually pretty strong. I’ve used pet urine, stain and odor spray, it didn’t help. We used a carpet scrubber on it twice and I don’t think its helping. Any helpful hits or ideas? I just want the smell gone!
Blot. Then sprinkle kind of a lot of baking soda. Then pour vinegar. It will fizz. Let dry. 24 hours probably. Vacuum. Only set back: your carpet will have a “clean” spot”. Dog will just pee another spot, tho.
Rocco & Roxie’s Professional Strength Stain & Odor Eliminator lives up to its name. This efficacious liquid will quickly and easily remove odors, but where it really shines is in handling those super hard stains.
Step 4: Once the carpet is almost dry — which could be several hours later — sprinkle a little baking soda on the area to absorb the odor. Allow the baking soda to settle into the carpet fibers for about 15 minutes, then vacuum the area.
It is great if you noticed the puddle immediately and started to clean up. But what should we do if the carpet is already dry and we need to get rid of dog pee smell? We should mix one cup of hydrogen peroxide with 1 tablespoon of dishwashing soap. Using the brush wash the spot properly. It is better to wash even a bit bigger surface than the spot itself.
Full sized cleaners can be something of a bear to handle. This makes them less ideal for those who aren’t quite as physically fit and also makes them harder to use in particularly tight environments. For a small apartment, inhabited by a smaller person, it doesn’t make sense and instead, you’ll want to focus on more pet oriented applications.
Understanding a little about the behavior and physiological capabilities of your pet helps in understanding why enzymatic cleaners are so useful for removing pet stains. Dogs and cats have a much more highly developed sense of smell than humans do and can detect odors that we cannot smell. We think the carpet is clean because the odor and stains are gone–and then the dog/cat returns and pees on the same spot.
