How to Remove Dog Urine Smell From Concrete

Pet urine smell in concrete is awful and embarrassing, and can ruin a home or animal shelter. I’m able to solve this problem for my clients so I thought I would share how to remove dog urine smell from concrete. Concrete is extremely porous and absorbs odors quickly. For example, daily cleaning can disinfect the surface of the concrete but the bacteria hides deep inside the substrate causing awful smells to continue.

How I permanently solve this problem for my clients is by using this combo, one two punch that knocks out the odors once and for all. Specifically formulated for pet odors caused by urine and defecation, this trick neutralizes the preexisting bacteria and then locks out any new odors from entering. Here’s my little secret…

Secret #1

To clean and neutralize the odors I immediately use Odor Kleanz, instead of other brands of enzyme cleaners, because it continues to break down the organic material like pet stains for days after cleaning the surface. For example, it has beneficial bacteria in it, unlike all other enzyme cleaners I know of. These beneficial bacteria break down the bad bacteria that cause the odors for up to a week after the substrate is dry. All other enzyme cleaners stop working as soon as the concrete is dry… which is why Odor Kleanz works SO much better than all the other cleaners I’ve ever used.

I give this cleaner to my clients because it can also be used as a maintenance cleaner. So any future accidents can be easily cleaned up and the odor causing bacteria is eliminated… awesome!

Plus, it’s pet and human friendly… meaning it’s non-toxic and super low in VOCs.

Cleaning Your Concrete

Skip this step if your concrete is free of paint or other sealers. Your concrete should have any preexisting surface sealers or paint removed first. This can be done using an over the counter floor strippers like Blue Bear Soy Gel Stripper floor stripper or Scorch Stripper, pressure washer, or a floor machine equipped with stripping pads. Then the floors need to be thoroughly cleaned / degreased to remove any stripper residue.
Next, clean the floor with Odor Kleanz. Just pour the cleaner and water at a 50% / 50% ratio (1×1) into a clean pump sprayer. Any cheap weed sprayer from the hardware store will work. Spray down the solution until the surface looks completely wet. Scrub the areas vigorously with a deck brush or push broom. The more you agitate the surface the better it works. Spray more down if any areas start to dry up.
After scrubbing the areas for at least 15 minutes, rinse the concrete thoroughly. For interior applications you can wet / dry vacuum up the dirty water and rinse water after cleaning. You can also use a mop to remove the dirty water and rinse water as well. Let the concrete dry and Odor Kleanz will continue to work it’s magic for days after.

Secret #2

This is my second little secret that’s amazing and makes my company crush our local competition. See, your concrete just sucks up the odors and they’re practically impossible to get out… until now. I always use Odor Shield sealer after cleaning desecrated concrete with Odor Kleanz. To clarify, Odor Shield soaks deep into the concrete and chemically reacts with the minerals inside the slab. As it cures it fills in the voids in the concrete where fluids and bacteria hide out. The concrete is now permanently more dense and completely waterproofed. So when your pet desecrates the concrete the fluids will sit on top of the surface, not soaking in like they use to.

Clean up any new messes by rinsing the area with water and scrubbing with Odor Kleanz. This should completely remove any smell from the area… yay!

Plus, Odor Shield pet and human friendly… meaning it’s non-toxic and VOC free.

Sealing Your Concrete

Just pour Odor Shield into a clean pump sprayer… you can rinse out the sprayer you used for the Odor Kleanz and use the same one. Spray down the sealer until the surface looks completely wet. Let it soak in for about 20-30 minutes.
If there’s any sealer left on the surface after the 20-30 minutes you should remove it. I usually use an old bath towel and drag it across the surface, then throw it out. Or you can mop it up with a dry, clean mop head. A wet / dry vac works as well… easy peazy! Keep the area completely dry for 24 hours, and as soon as it looks dry you can have full foot traffic on the treated area.

Conclusion

In conclusion, when you follow this step by step process it will permanently remove preexisting pet urine odor from concrete and will prevent it from coming back. This is the combination I use for my clients when I get calls about pet urine odors in their concrete. Over the years I’ve used many other products on the market and this combination works the best… by far. I’m proud to say that I’ve helped with the testing of these products along the formulation process to ensure that they work above any beyond all the other cleaners and sealers I’ve tried… pretty cool.

You can use this in your home, basement, kennel, vet clinic, dog walk, or outside patio. In addition, what’s cool is it doesn’t change the look of the concrete. And it also won’t leave a powdery residue on the concrete like other penetrating sealer do.

Another fun fact, since Odor Shield increases the density of the concrete it can be used during the polishing process as well. I usually add it after the I’m done with the lower grit levels and I also add it right before the final step of the polishing for maximum protection and shine enhancement. This is a great option for kennels, pet stores, or other commercial polished concrete floors looking for that extra protection against pet accidents.
