Tips to Make Your Concrete Odor-Free from Dog and Cat Urine

We all love our pets, even though they can create some little accidents sometimes. Sure you can clean a carpet easily in case they’ve urinated on it. But when it comes to your garage, it’s another side of the story. Listed below are a few tips to keep your garage floor odor-free from your pet’s urine.

Before anything else, cleaning urine out of concrete is a multi-step process. The good thing about the tips listed below is that it not only cleans urine odor, it also helps prevent further issues to happen.


  • Concrete may be sturdy to look at, but its porous nature is the real challenge here. Meaning, every liquid can enter in and sink deep down if not taken care off early. Even worse is the smell coming from the urine can lie dormant after it dries. And it can be re-activated when you pour another form of liquid into it. The best thing you can do is to perform deep cleaning to completely eliminate its smell. Sealing the surface after doing such will prevent further damage.

Preparing to Clean

  • Before you start scrubbing the floor, ensuring the entire floor is completely dust-free is the first thing you should do. Begin by using a push broom to sweep the floor away from any tiny particles and debris.

Locate Urinated Areas

  • Now that the floor is clear from any dust or any kinds of particles, it’s time to locate the spot where your pets peed at. Use a blacklight to scan the floor from any signs of pee. Once found, use a chalk to mark the spot for east spotting later. And now for the cleaning process!

Step 1: The Initial Clean

  • There are three types of concrete cleaners that you can use. Both of them are chemical and non-chemical. Let’s have a look at them!
  • Hydrogen Peroxide – This one can yield good results but can take a few days before you can see its effects. Take two drops of Dawn paired with two teaspoons of baking soda. Add them to two cups of hydrogen peroxide in a glass bowl. Mix well until the baking soda is completely dissolved. Once done, spray or pour the mixture on the urinated areas. The solution will soak deep into the concrete, completely eliminating urine. Repeat every 24 hours in between days until the smell is completely gone.

  • Trisodium Phosphate (TSP) – This one is a heavy duty cleaner that can get rid of urine traces and eliminates bacteria. You should be careful when handling such as TSP is known to create skin damage when in contact with skin. Wearing protective clothing and also goggles is advisable and keep your kids and pets away from the area when doing your cleaning operation. Make a mixture by adding ½ cup of TSP on a tub of hot water. Pour the mixture on the affected area and make sure that it doesn’t exceed three square feet or more since it evaporates quickly. Scrub the spot in a gentle manner and allow the mixture to sink in for at least five minutes. Apply more into the urinated are if needed. A very strong odor will be present when doing such so make sure to cover your nose. After doing such, rinse the affected area with hot water.

  • Vinegar – One of the most common and cheapest ways to clean the area is probably using vinegar. Mix two parts of vinegar into hot water and pour it on the affected area. This method is probably the most effective one as it works perfectly to fight urine odors. If TSP is too dangerous for you, then use this one as an alternative.

Step 2: Treating the Stain

  • Now that you’re done removing the odor out of the concrete, it’s time to seal the entire floor by using an enzymatic cleaner. Keep in mind that you only removed the “smell” of the urine and not the urine itself.
  • Enzymatic Cleaner – This type of cleaner comes in concentrated form and it’s known to break down uric acid that sinks deep down into the concrete. Make sure to follow the instructions carefully when using such to avoid any problems later on. To start, pour a portion of the cleaner into the stain and leave it for at least 10 minutes to let it soak in completely. Use a scrub to brush tough areas. After that, allow the floor to dry overnight. Now that the floor is completely dry, it’s time for the final step.

Step 3: Preventing Further Issues

  • For the final step, it’s time to seal the floor to prevent further issues by using a protective coating. Protective coating not only seals and protect, but it also prolongs the life of your floor too.
  • Concrete Sealer – When shopping for a concrete sealer, it’s best to opt for one that can protect your floor for the years to come. After purchasing one, follow the instructions carefully before starting. Rinse the floor thoroughly after applying and let it dry for at least 24 hours. Lastly, seal any leftover cracks using caulk to prevent urine or any kinds of liquid to enter in next time.
  • Results may vary depending on the type of sealer you used. Some sealers remain dry and clear while others will give your floor a glossy finish that can make it attractive. Keep in mind that result will not instantly show up in just a day. Some sealers will need at least 3-4 days before it completely cures.
