Dogs can be a great source of joy and companionship, as they are loyal and loving animals, but they also come with their own fair share of messes. Quite often they will rip up trash, dig holes in the yard and, of course, be very messy eaters. One such mess is urine, which can leave an unpleasant smell on concrete surfaces if your dog is not toilet trained. Learn how to get rid of dog urine smell on concrete.

While this last one may not seem like a big deal, the truth is that dog urine can cause major staining and discoloration on concrete surfaces. It can also create an unpleasant smell that lingers long after your pet has relieved themselves. Thankfully, there are a few simple steps you can take to get rid of the dog urine smell on concrete and keep your home looking and smelling fresh.

Why Is Dog Urine on Concrete So Smelly?

Dog urine comprises many different compounds that contribute to its strong smell. The urea present in urine is turned into ammonia when it decomposes, and this is one of the main components that smells so bad. The pungent odor that is typical of dog urine is also caused by other compounds such as mercaptans, thiols, sulfides and disulfide, and even ammonia.

The other main component that contributes to the powerful smell of dog urine is bacteria. When urine is left on concrete, the bacteria present will begin to multiply and release foul-smelling gases. These gases can be extremely potent and difficult to get rid of.

7 Classic Cleaning Methods: Do They Really Work?

1. Bleach

Clorox HE Performance Bleach, 121 Oz. (Pack of 1)

Bleach is a powerful disinfectant and can kill bacteria. However, it is also a harsh chemical that can damage concrete. If you decide to use bleach, be sure to dilute it with water and always test it on a small area first. Also, the smell of the urine may continue to linger even after bleaching.

2. Ammonia

Austin's 00051 Clear Ammonia Multipurpose Cleaner - 64 Ounce

This is not normally a cleaning product you would think of using on concrete, but some people swear by it. Like bleach, it is also a powerful disinfectant. However, you need to be careful with ammonia because it can also damage concrete and not even be very effective at removing urine odor.

3. Soap and Water

Softsoap Liquid Hand Soap, Fresh Breeze - 7.5 Fluid Ounce (Pack of 6)

CRYSTAL GEYSER SINCE 1977 Purified Water 1 Gallon, 25.4 Fl Oz, (Pack of 2)

This is utterly the most straightforward method, but unfortunately, it is also the least effective. Soap and water will only remove surface dirt and grime; it will not do anything to remove the urine odor from concrete. This is because the odor is coming from the pores of the concrete, and soap and water will not reach those.

4. Vinegar and Baking Soda

Heinz Cleaning Vinegar (1 gal Jug)

ARM & HAMMER Baking Soda, 5 lb

One of the most effective cleaning solutions for removing urine odor from concrete is a mixture of vinegar and baking soda. The vinegar’s acidity will help break down the urine, while the baking soda will absorb the odor.

5. Trisodium Phosphate (TSP)

Trisodium Phosphate TSP 4.5 Pounds with Centaurus AZ Resistant Glove for Commercial and Industrial, Powerful Degreaser, Grease, Grime, Smoke, Soot, Clearing Oil Stains, for Concrete, Brick and Walls

A less common but more effective cleaning solution is Trisodium Phosphate (TSP). This is a strong chemical cleaner that is usually used for heavy-duty cleaning jobs. It will remove the urine odor from concrete but can also damage the concrete if not used properly.

Be careful when using TSP and always follow the directions on the package as well as any safety precautions.

6. Hydrogen Peroxide

A little safer and more gentle solution is hydrogen peroxide. Hydrogen peroxide will also break down the urine and remove the odor. It’s a good alternative

7. Enzymatic Cleaner for Concrete

Simply the absolute best of the best product you could use is an enzymatic cleaner. Enzymatic cleaners are specially formulated to break down the urine and remove the odor. They are safe to use on concrete and will not damage the surface.

Gather Your Materials

  • A bucket

Pre-treat the area with a pet odor eliminator or enzymatic cleaner. These products are designed to break down the urine and remove the odor. See the section above for more information on enzymatic cleaners.

If you don’t have a pet odor eliminator or enzymatic cleaner, you can make your own cleaning solution with vinegar and baking soda. The vinegar’s acidity will help break down the urine, while the baking soda will absorb the odor.

Let Dry and Repeat 

Let the cleaner sit for the amount of time recommended by the manufacturer. After treating the area with a pet odor eliminator, wash the concrete with soap and water. This will remove any residue from the cleaner as well as any remaining urine or repeat as necessary.

Consider Waterproofing Your Concrete Floor

There are many different types of waterproofing sealers available, so be sure to choose one that is compatible with your type of concrete.
