Seven Best Carpet Cleaners For Dog Urine

1. Rocco & Roxie Supply Co. Professional Strength Pet Stain & Odor Eliminator – Best Overall Cleaner

Rocco & Roxie Supply Co. Professional Strength Pet Stain & Odor Eliminator

Click Here For Price

Probably the most effective cleaner when it comes to dealing with both stains and odors, this product from Rocco & Roxie is designed to both completely eliminate odors and lift stains.

Product Features

  • Spot cleaning and pre-treatment
  • Natural bacteria enzyme-activated formula
  • No chlorine or harsh chemicals

This is a spray best used immediately on stains or as a pre-treatment before shampooing for older stains. It uses an enzyme-activated formula that contains natural bacteria that activates when it comes into contact with stains and odors.

It can also be used to freshen up areas such as pet bedding and litter boxes that might still be holding onto a lingering smell despite cleaning with other products.

As well as working for urine, this cleaner has been tested and proven effective for other tough stains such as feces, vomit, and blood. While this level of power may raise concerns about damaging carpets and how safe it is to be around, this formula is pretty safe. It does not contain chlorine or other harsh chemicals that can damage carpet fibers or prove dangerous to you or your pet.

However, both you and your pet may find yourselves avoiding the area for a few days after cleaning, as the cleaner has a strong and sharp smell that can be a bit unpleasant until it dissipates. This formula is also relatively expensive when compared to some of the other products on this list.

Pros:

  • Natural bacteria formula
  • Eliminates odors
  • Powerful stain remover
  • Safe for animals and humans
  • Does not damage carpets

Cons:

  • Strong smell
  • Expensive

Despite the temporary strong after smell, if you are looking to eliminate odors and stains quickly and effectively without resorting to harsh and dangerous chemicals, this formula from Rocco & Roxie is probably the best on the market.

2. TriNova Pet Stain & Odor Remover – Best For All Natural Cleaner

Product Features

  • Spot cleaning and pre-treatment
  • All-natural formula
  • Professional strength

This all-natural formula is completely plant-based and uses natural enzymes extracted from plants to lift stains and neutralize odors. It is completely free from harsh chemicals. Also, it works quickly, and you will see results within a couple of minutes of applying the formula to the area. Lastly, it is also an effective pre-treatment for carpets before shampooing or steam cleaning.

While the product will break down and eliminate odors, it also deposits a light herbal odor for masking in the immediate aftermath of cleaning. This scent is much milder and less offensive than the scent of many similar cleaners.

As well as being completely safe for carpets, animals, and humans, this cleaner is highly affordable, especially considering the hefty price tag that usually accompanies all-natural products.

Pros:

  • All-natural formula
  • Strong stain remover
  • Good odor elimination
  • Safe for animals and humans
  • Will not damage carpet
  • Light scent

Cons:

  • Less effective than some other formulas

This is an all-around quality product that you can feel good about using, and the only reason that it is not number one on this list is that it is a little bit less effective than the Rocco & Roxie formula which also uses natural ingredients and avoids harsh chemicals.

The formula will also soak into stains to help remove them but is not as effective as some of the other spot cleaners on this list. However, it is a good interim solution for dealing with odor and stains between regular carpet cleanings.

Pros:

  • Affordable
  • Eliminates odors quickly
  • Discourages repeated peeing

Cons:

  • Not as strong on stains

This is one of many excellent carpet cleaning products from Nature’s Miracle, all of which deserve a look though I have picked this one as the best of the best for this list.

Product Features

  • Carpet shampoo
  • Biodegradable
  • Bio-enzymatic odor elimination

Rather than a spot cleaner, this is a carpet shampoo designed to be used with water-based carpet cleaning machines. This method of cleaning delivers this powerful product deep into the carpet fibers to tackle both fresh stains and older ones that have proven difficult to lift.

The shampoo formula uses a bio-enzymatic odor locking technology that should be able to eliminate even the strongest and most stubborn odors. This results in a strong formula but one that is safe for carpets and also safe for the environment. This shampoo is biodegradable, so it is safe to discard used cleaning water in the garden.

As with many of these cleaners, the biggest complaint is that in the immediate aftermath of cleaning it can leave behind its own harsh smell that may keep you and your dog out of the house for a few hours.

Pros:

  • Biodegradable
  • Safe for animals and humans
  • Can be used with steam cleaners
  • Will not damage your carpet

Cons:

  • Harsh smell

Product Features

  • Hydrogen peroxide-based formula
  • Heavy-duty stain removal

This spot cleaner can be applied directly to stains without fear of damaging carpet or upholstery. Using a unique hydrogen peroxide-based formula, it is best to leave in place for five to eight minutes to soak into the stain before removing. 

While this is longer than some of the formulas that boast action within 30 seconds, this allows it to really soak into the stain and take everything away with it. It manages to do this while being completely safe for carpets, animals, and humans and without leaving behind the strong smell of cleaning agents.

While this formula is one of the best when it comes to stains, it is less effective with odors than some of the others on this list despite containing bacteria, enzymes, and odor neutralizers. The rather hefty price tag is the other reason that it has not come higher up on the list.

Pros:

  • Heavy-duty stain removal
  • Safe for animals and humans
  • No strong after smell

Cons:

  • Expensive
  • More effective with stains than odors

If it is stains that are causing you problems, and you have deep stains that need dealing with, this formula provides a safe and effective way to return your carpets to new.

Buying Guide

The Problem

There are many reasons why you might find your dog peeing on the carpet. It could be that they are still learning and therefore expected accidents happen. If you are still toilet training your dog, check out these helpful potty training tips. But even well-trained dogs will sometimes relieve themselves inside the house.

Your dog might find themselves accidentally peeing inside the house if you leave them inside too long, and they are left with no choice but to relieve themselves. 

However, they might also go ahead and pee on the carpet as a result of over excitement. According to vet Dr Lisa Radosta:

Dogs who exhibit excitement urination do not show submissive body language. Instead, they exhibit joyous behavior such as wiggling, jiggling, and jumping as they happily urinate on the floor. This often leads to the spraying of urine everywhere.

Accidentally peeing like this can also be brought on by fear, as they may let go of their bladder in response. But hopefully they have no need to feel particularly fearful while inside your home!

Dogs may also actively choose to pee inside the house as a way of marking their territory. This will usually happen if another pet is introduced into the home. The older pet will want to clearly mark their territory with their scent. 

While you might think that this is a one-off price to pay when getting a new pet, once they start urinating in this way it can become habitual, and it can be difficult to train them out of this behavior. The bacteria left behind by their urine can also encourage them to come back to the same spot to pee again in future.

Finally, sometimes an inability to control their bladder can be a sign of a medical disorder, such as kidney stones or diabetes. If you can’t see any other explanation for their peeing, it might be time to take them to the vet just to be sure. According to Dr Radosta: 

Medical disorders increase urgency so the dog can’t get outside fast enough. If that is the case, they will go wherever they happen to be standing.

While initial cleaning might mask the smell of dog urine, if you do not fully eliminate the odor and sanitize the area, the smell of dog urine has a way of permeating the home in a way that is difficult to ignore and eliminate. 

While immediate clean up is the best thing that you can do, sometimes we do not notice dog urine right away, as it does not usually smell terribly when it is fresh. It only starts to smell as it breaks down in the presence of oxygen. This means that stains can have already started to set in by the time we get to them. 

Old stains that have not been cleaned properly should also not be ignored, as they can still contain odor-producing bacteria and bacteria that will attract your dog to pee in the same spot again.

Cleaning Solutions

Cleaning up dog urine is generally a two-part process. First, you will want a spot cleaner to deal with odors and stains immediately, cleaning up the affected area as quickly as possible. While there are a lot of very effective spot cleaners on the market which may leave you thinking that the area is clean, it is best to follow up with regular carpet shampooing with special shampoo targeted at stains like urine to ensure that all underlying bacteria, odors, and stains are fully eliminated.

In order to be effective against dog urine, your selected cleaning agent needs to be strong but not so strong that it damages your carpet, and it also should not contain any harsh chemicals that could be dangerous for either your dog or you. These days, carpet cleaning formulas generally work in one of two different ways:

Enzyme Cleaners

Enzyme cleaners contain special enzymes that latch onto the bacteria left behind by urine and other substances and then diminishes that bacteria until it is virtually undetectable. These are generally the best cleaners when it comes to eliminating odors.

Oxygen Cleaners

Oxygen cleaners use an oxidizing compound that releases oxygen when it is exposed to water. This release of oxygen lifts stains and dirt off whatever surface is being cleaned. These cleaners are generally less effective on odors than enzyme cleaners but more effective when it comes to stains.

While there are still cleaners available out there that use more traditional chemicals such as chlorine and bleach, these are not recommended since they can damage your carpet and be harmful to anyone, animal or human, living in your household.

Key Features Of A Good Carpet Cleaning Solution

Once you have decided whether to go with an enzyme or an oxygen cleaning solution, there are a number of other features of a good cleaning product to consider:

Natural/Biodegradable

What are you planning to do with your cleaning water once you have dealt with your urine stain? Pour it down the sink? Dispose of it in the garden? The best cleaning formulas will be natural and biodegradable so as not to cause damage to the environment when disposed of. This is especially important when it comes to carpet shampoos, simply because you are using a lot more water.

Odor And Scent

When it comes to cleaning up dog urine, you want to eliminate the bacteria that causes it to smell rather than just mask the smell with a home-friendly scent. The bacteria in dog urine that causes it to smell takes months to fully break down. This means that if left unattended, it can still be giving off fresh smells weeks after the offending incident. 

The smell of this bacteria can also act as a calling card for your dog, encouraging them to return and pee in the same spot. This is why it is essential to use a cleaner that breaks down odors and does not simply mask them. Moreover, generally speaking, in order to be strong enough to mask the smell of dog urine, cleaning scents need to be pretty strong which can be offensive to the nose in its own right.

Carpet, Animal, And Human Safe

As already suggested, it is important to avoid cleaners that contain nasty chemicals. Obviously some chemicals can do damage to your carpet, stripping color, and causing fibers to harden. More worrying, however, is the health damage that they can do to human and animal members of the household when they come into contact with or inhale the chemical. Any cleaner you choose should be certified as safe for animals and humans.

Safety Precautions

In order to completely minimize risks, it is also a good idea to take some safety precautions when cleaning carpets:

  • Wear gloves when cleaning to protect your skin.
  • Keep the space well ventilated during and after cleaning to dissipate any smells left by the cleaning agent.
  • Avoid using cleaning products near an open flame or electrical outlet.
  • Everyone, but especially children and pets, should keep away from the carpet that has been cleaned until it is completely dry.
  • Close containers properly after use to ensure no fumes escape.
  • Store cleaning products out of the reach of children and pets and away from food products.
