It is important to identify the dog’s urinated area before initiating cleaning. Dogs usually urinate in designated areas where they have urinated before. If your dog goes to the concrete patio area only with you then you have likely seen where they usually urinate. But if for some reason you didn’t see your dog urinating but rather have seen a urine-like strain or smelled such odor then the work becomes a bit harder.

Concrete patios are pervious, meaning they will soak the dog’s urine just like any other thin liquid. The only two remaining things will be a distinct strain made of urea, creatinine, uric acid, etc. contents, and bad odors. Some of the strain may not be easily visible due to the concrete color texture but you can use technologies to help to find those strain marks. You can use UV-reflecting light at night which will deflect in the strain area and give you a clear clue where your dog urinated.

How To Clean Dog Urine From Concrete Patio?

After you have successfully traced all the possible dog urinated locations, it is time to deep clean them forever. There are multiple options for you to clean it, depending on the urine, strain, odor level, and cleaning materials availability. Some of the proven methods to clean dog urine from concrete patios are:



The primary method of dog urine cleaning will be using as much as water through a hose or sprinkler. It will wash away the excess amount of urine and odor at the same time. Use high speed and narrower output settings in the water hose to generate high pressure. Instant water spraying is effective in removing recently peed cases. But remember one thing this very method can cause the opposite by spreading the urine further. Make sure it is only applied to the edges of the patio and, if the urine is in the middle then soak the urine as much as possible before applying water.

Wash With Soap And Detergent

Wash with soap and detergent

In most cases washing the dog’s urinated area with bare water isn’t enough. Dogs’ urine contains odorous elements that may still remain even after a normal watery wash. For that, you can use normal soap and tile-cleaning detergents to reduce the urine impact even further. Put your hand gloves on, get on your knee, and start to scrub the designated area with soap and detergent. If not the urine goes away by this method, it will still reduce them drastically and lay a base for further steps to work upon.

Trisodium Phosphate (TSP)

The TSP is effective at removing all the bacteria, and dog urine stains left on your concrete. Make sure to use eye and skin-protecting gear and keep the children away. Here are its application steps:

  1. Mix ½ cup of TSP with a gallon of hot water.
  2. Pour the hot mix on the designated urinated areas.
  3. Scrub the designated urinated area with a deck brush.
  4. Leave it wet for 10-15 minutes to reach deeper into the concrete.
  5. Rinse the area with fresh hot water.
  6. Repeat this method several times.
  7. Let it dry overnight.

TSP has been banned in some states, so check your local laws before purchasing any.

Hydrogen Peroxide And Baking Soda

Hydrogen peroxide and baking soda

Hydrogen Peroxide is best used against stains that contain carbon or protein, such as dogs’ urine. Hydrogen peroxide breaks the stain molecule easily. Also, it is an eco-friendly option as it can be washed away with water.  It application steps:

  1. Mix 2 cups of Hydrogen Peroxide, 2 teaspoons of baking soda, and a little dish soap.
  2. Spread this formulation over the dog’s urinated areas.
  3. Let the application soak for a few minutes to break the molecules.
  4. Scrub the applied area with a stiff feathered non-metal brush.
  5. Repeat this method several times and rinse with fresh water.



If you want something more home sourced you can use vinegar for cleaning dog urine. Take some vinegar and mix it with hot water.  Spread it over the recently urinated area and wait a few minutes to set over the urine bacteria. Scrub the area and rinse off with hot water. Note that using vinegar is effective when it is recently urinated. And don’t forget to soak the liquid urine away as much as possible before applying vinegar.

1. Will bleach get rid of the dog urine smell on concrete?

It is better not to use bleaches to get rid of dog urine as dog urine contains ammonia. When bleach comes in contact with a dog’s urine, the reaction causes toxic fumes and bad odors to be released.

2. Can dog urine damage concrete?

Dogs’ urines contain toxic chemicals that can leave a layer of uric acid crystals. This crystal can put a wick into the gel pore system of the concrete and, allow bacteria to grow if not cleaned properly.

3. Which one of the urine is worse, cat or dog?

Cats’ urines are much more concentrated than dogs. Whereas a dog’s urine is less yellow and sticky. Meaning a cat urinates less times than a dog but their smells are more awful.
