Bleach may take the color out of your carpet. Before using any carpet cleaning product, it’s recommended to do a test spot first in an inconspicuous area before using the product on the entire carpet. A carpet cleaning professional might be the best option for dealing with tough, set-in stains.
If you have thick carpeting and padding, like I do, it does NOT work well at all. I spent the better part of half an hour attempting to get the water sucked out of the stairs with the hand tool. In order to get it to work well, you have to press down HARD, otherwise, it doesn’t suck the water out completely. No problem? Well, the brush works basically with the suction. When you press hard (being a weak upper body person, that meant I had to throw my weight into it), it stops the brushes from spinning. Kind of the entire idea of the tool, I would think. I ended up using the entire shampooer, not the tool on the larger/curved stairs at the bottom of our staircase and the tool to complete the top thinner stairs-which there are more of, hence the half hour cleaning time for 22 stairs. Basically, the stair tool is a “dud”, in my opinion, unless you have thin carpet. Even then, I think the brush spins rather weakly, making it not really a scrubbing tool. I still LOVE this shampooer and have very thick carpeting and padding which is able to be walked on within 2 hours and bone dry after 4-5 due to the great suction on this machine.
Absorb smells with a deodorizer. There are lots of deodorizers that can target pesky pet smells. You can purchase one from the store, or make your own if you’re feeling crafty and thrifty. Two of the most popular items are baking soda and vinegar, which you can spray around the house, on carpets, on beds, and elsewhere to help remove smells. To make your own deodorizers:
I use SCOE 10X which I can only buy online. Unlike others, it is probiotic based. Nothing else worked for dog urine odor. Be sure to soak thoroughly and then rinse thoroughly with a wet-dry vacuum and water, or it may pick up soil later. Normally this does not happen, it just depends on how much I have to use.
3. Works very well at stain removal using just the beater bar/floor tool and no attachment/hand held for tough foot traffic stains. I have not used it to remove set in pet stains so far as I use a “cat urine” eliminator “Get Serious” to remove the cat urine smell and it also removes the stains. I haven’t tried to remove old urine stains yet with it since I have none after having used GET SERIOUS. It does remove yellowed spots where I have allowed the cat urine to set for long periods (because it was behind a piece of furniture that only gets moved once a month when we move it to vac under it), but a month is hardly time to judge a yellow urine stain as “set in”. I have removed brown rust colored stains that the last professional carpet shampooer company “brought up” (Funny, they were in the middle of an open room and at the base of our stairs where no stain was prior to their coming and the stain wasn’t there until we refused for the umpteenth time their attempt to up-sell us on worthless products!!) and I had previously been unable to get that stain out using my Little Green Machine without it coming back up to the surface after a few weeks. I have only had this machine two weeks and have used it on the room 3 times in order to do a deep thorough clean and also to try and get some pet hair out. I have used it in “spots”, too but only a total room clean 3 times.
Soak up as much of the urine as possible: Place a thick layer of paper towels on the wet spot, and cover that with a thick layer of newspaper. If possible, put newspaper under the soiled area as well. Stand on this padding for about a minute, and repeat until the area is barely damp.
Obviously the best long-term solution is to get the little guy going potty outside. I am not sure what your process is, but adding the use of a crate/kennel (or in your case pen) to the regime can be helpful, in addition to positive re-enforcement. It’s a total pain, but it really cuts down on the accidents and is worth it in the long run. So for example as soon as the puppy wakes up, take him outside to go potty. If he goes throw a party and have a little play session. If he doesn’t go within 5 minutes or so, bring him back inside and place him in his pen-there isn’t any fun time until his business is done. Anywhere from 5-15 minutes later repeat the above process. When he does go, he gets let out to play run around etc. etc. but not before. Again it’s a hassle, but it really cuts down on missing any accidents in hidden places, and they pick up quick on the positive re-enforcement and learn to hurry up and potty so they can play!

Sally grew up in a feline-only home, but cat allergies in her early 20’s made it an easy transition to dog ownership. And she couldn’t be happier with her canine shadow, who’s been at her side (literally) for years. No longer a cat person for obvious reasons, Sally is now a true bone-ified dog lover.
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.

Many of these pet carpet cleaners feature enzymes that break down odor-causing ammonia within their biological waste, while containing no harsh chemical fumes or smells of their own. They also dry quickly to minimize the potential for tracking the mess through the house. By successfully eliminating deep-set messes, you’ll also be able to get rid of the harmful bacteria and the foul odors they can cause.

I have been removing pet urine and human urine professionally for 27 years with industrial strength hydrogen peroxide. we use 30% H202. you can buy 20 volume or 40 volume clear developer from a beauty supply co. this is peroxide used in bleaching hair. or buy strong peroxide from a pool store. only use on synthetic fibers, saturate carpet and pad, let dry 24 hrs. do not touch with skin til dry, shoes ok. keep pets off spot til dry. if you touch chemical wash immediately, rinse eyes for 15 minutes if contaminated, skin turns white and burns for 15 minutes after washing. the oxygen radicals will neutralize the urea, the odor,and kill the bacteria. it does not need to be rinsed. also works on red wine, blood, coffee, and mold. this is a trade secret. use enough strong peroxide it works every time.
One important caution….These products can take the color out of cheap carpeting if left soaking wet to dry. Test in a closet first. If your carpets lose color than you can still pour on but must blot off, this will still help but will not be as effective as leaving it on.
This will get rid of a great deal of the smell, but to really do a thorough job, you might want to rent a carpet cleaning machine with an attachment for furniture – or call a cleaning company to do it for you. Always start with neutralizing as much of the smell as possible before the shampooing, though, or all you will be doing is creating a hybrid of dog smell and perfumed shampoo. Not a good combination. And don’t use carpet shampoo on the furniture, or you could end up with ruined and smelly furniture.
Really helpful! The light sounds especially useful, as I have mostly black and other dark fabrics. Accidents are hard to spot! Our dog doesn’t actually pee in the floor, he is just one of those dogs that sprinkles when he is happy (and excited, scared, upset, sleeping, etc!)
It’s also important to consider your dog’s motivations for peeing inside. Sometimes, inappropriate elimination is a sign of a medical issue. It can also indicate anxiety or emotional distress. If your dog is peeing indoors, start with a vet visit to rule out physical causes.
I never have problems with pee. My problem is with a cat that throws up. How do you get those stains out. My brand new carpet is stained so bad it needs replacing again. Cat food is made of brightly colored
The Bissell Big Green is probably the most effective carpet cleaner we have reviewed. It has a large following amongst pet owners because of its extremely efficient cleaning of pet urine, pet vomit and pet stains.
To get your house to not smell like your pets, start by vacuuming all of the floors, carpets, and furniture in your house. Then, wipe down any upholstered furniture with warm soapy water and let it air dry, which will help eliminate odors trapped in the fabric. You should also machine wash your bedding, your pet’s bed, and your pet’s toys to get rid of any odors coming from them. Also, try opening up all of your windows and setting up an air purifier.
When you take her outside to pee, try to train her to pee on command. When she does pee outside, lots of praise, lots of treats, lots of love, make the act of peeing outside the most magical thing ever.

Apply another towel and absorb the cleaner. After soaking the spot with cleaning, follow the same procedure as with the first absorbing, and put a fresh towel over the enzymatic cleaner to absorb it and thoroughly cleanse the area. Weight the towel with a heavy object and leave it alone.
Once you have got the area as dry as you can, liberally sprinkle on ordinary baking soda, again working it into the fibers of the carpet with your fingertips (don’t forget the rubber gloves!), or an old, soft toothbrush.
1. Cleans and fluffs the carpet better than two national PROFESSIONAL carpet cleaning chains that I have used. I have 10 year old white carpet (purchased prior to adopting this goofy cat) and was about to replace it due to it being matted down (husband works from home and refuses to take off his shoes when he enters and leaves the home) and also due to it just being soaked with this cat’s urine for the last 8 years now and this really seemed to do the trick to help us put off buying hardwood floors for this area for several months now!
