How to Clean Dog Urine from Concrete Patio?

Some dogs and concrete patios are not a good combination. Dogs can urinate on the patio at will and for many types of reasons. They could smell another animal, not want to go out in the yard because of rain, or be afflicted with arthritis as they age. The result is a stain and, worse, a smell. 

There are different ways for how to clean dog urine from concrete patio. You can use vinegar, baking soda, hydrogen peroxide, an ion-based product an enzymatic treatment, or a combination of methods. 

Read on for information on how to remove dog urine from concrete.

The Problem with Urin and Concrete

Dog urine on concrete patios presents more than a few problems. First, concrete is porous, so the urine seeps down if not cleaned up immediately. Dog urine can stain but also has a strong smell that will not go away with time. 

Even when you think it’s gone, it comes back in a whiff of a breeze or on a rainy day. 

Another problem is once a dog urinates somewhere, he will return to urinate in the same spot every time. It’s his personal security system.

Cleaning Up Dog Urine from Concrete Patios

Ways exist to clean up both the stain and smell of dog urine from a concrete patio but it’s no easy feat. It may take some repeated efforts. Check out these tried and true methods below. 

Finding the Spots

Some dogs will always pee in one spot. Others will test out several areas. You will need to find all areas where the dog has urinated to clean them. A black light will do the trick. 

Scan the entire patio and even the walls. Urine stains will look like green, yellow, or blue under the light. Mark the spots with chalk. Now comes the cleaning

Trisodium Phosphate (TSP)

Trisodium Phosphate removes all bacteria. Yet, the uric acid crystals must be removed with an enzymatic pet urine cleaner because the TSP doesn’t take them out.

Mix 1/2 cup of TSP for a gallon of hot water. Be sure to wear gloves and eye protection as you use this chemical. Don’t allow pets or children onto the patio. 

Pour the water mix on the areas where there is urine one spot at a time and scrub with a deck brush. The mix evaporates fast so do one spot at a time. It needs to stay wet for at least 10 minutes. 

The smell will worsen because uric acid crystals release gas as the liquid covers them. 

When you’re done scrubbing all areas, pour clean hot water over the patio. Dry it with a wet vac to remove the water. Rinse two or three more times and let the concrete dry for 24 hours. 

Some areas may look whiter than others so you may have to do it several times to different areas to get a consistent look. 

Next, you will need an enzymatic cleaner to treat your patio. With this cleaner, other types of bacteria break down uric acid crystals into carbon dioxide and water. 

Use a deck brush to scrub the product into the concrete and let sit for 10 minutes. The longer the better. Cover with a tarp to leave it to dry overnight if you can. You don’t need to rinse it.

Hydrogen Peroxide Mix

Hydrogen peroxide mixed with baking soda is a good chemical to use to clean dog urine if you don’t want to use TSP. Mix two cups of hydrogen peroxide with two teaspoons of baking soda and a quarter cup of dish soap. 

Pour over the stain and let soak. After it seeps in a bit, scrub and rinse off as before.

Vinegar Mix

You can also mix vinegar with baking soda to get the same cleaning effect on dog urine stains on concrete. Mix the vinegar in a two to one ratio to hot water and add the two teaspoons of baking soda. 

Pour and let sit. Then, scrub and rinse. 

You may want to test an area first because using vinegar should leave marks or patterns in the concrete. The advantage of using vinegar is the smell stays with the concrete and that stops the dog from urinating there.

Combination Effort

Some people use several different things to give the urine stain a double dose of cleaning power. The process is to put down dry baking soda over the stain to absorb any left on top after you initial clean up the wet. 

Pour white vinegar over the baking soda slowly. It will change into foam that goes into pores. Let it stop foaming and then scrub with a deck brush and rinse with clean water. 

Positive-Ion Treamtents

A positive-ion treatment works well with new stains. Soak up as much of the urine as you can from the concrete. Pour water on the affected area and apply the treatment, following directions. 

This will work immediately on new stains. Older standing may have to be repeated several times to break up the urine crystals and neutralize them.

Why Household Cleaners Won’t Work?

Many people try using typical household cleaners to get rid of dog urine stains and smells but they usually don’t work. You may not see or smell it for a while but both will come back when there is moisture on your patio. 

Sometimes the smell can be stronger than ever. 

Urine crystals bond with the concrete deep down. Soaps and cleaning products don’t break down that bond or the crystals. That’s why you need certain products with particular acids and chemicals.

Once you get your patio free of dog urine stains and odors, sealing it will protect it in the future. Sealants come in different shades, effects and can be used as a decorative element. They are as easy to put on as paint.

You will need to apply a sealer again about every three to five years.
