By following the steps in this article, you will be able to remove cat urine from concrete in no time at all. Just ensure you don’t skip any of the steps or use the wrong products, and your patio will be looking and smelling as good as new.

The steps that I will outline below will allow you to clean cat urine from your patio or driveway.

Note: These steps are the exact same if you were looking to remove dog urine from your patio, too!

What is the Best Urine Remover for Concrete?

The most effective urine remover for concrete is an enzymatic cleaner. Enzymatic cleaners are designed to break down the proteins in urine and eliminate the smell.

There are a few various types of enzymatic cleaners on the market, however, I recommend TSP powder and liquid.

TSP powder is a trisodium phosphate cleaner that is very effective at removing urine and other organic matter.

You can buy TSP powder at most hardware stores and also Amazon.

How to Clean Cat Urine From Patio or Driveway

Before you get started you will need the following items:

  • A kettle.
  • A box of TSP and/or liquid.
  • A gallon jug.
  • Masks, gloves, and safety glasses.
  • A metal wire bristle broom.
  • A scrub brush.
  • Water.
  • Bucket (may or may not use).
  • A wet and dry vac.

Step 1 – boil water

This method won’t work with cold or warm water, it has to be hot.

Put on your gloves, mask, and safety glasses. Fill a kettle with as much hot water as you can.

Step 2 – Fill Your jug with the hot water

When the kettle has boiled, pour the water into the jug.

Step 3 – Add TSP to the hot water

If you’re using the powder, add 1/2 cup of TSP to a pan with 5 quarts of water and bring to a boil. If you’re using the liquid, mix 2 ounces of TSP in 4 cups of warm water.

Step 4 – Stir until dissolved

Stir until the TSP is fully dissolved.

Step 5 – Pour mixture over the affected area

Pour the mixture over the affected area and use a metal wire broom to spread it around.

Note: If you’re not sure where the pee was dropped, an UV light may be used to reveal the region.

Step 6 – Let it sit for 5-10 minutes

Let the mixture sit for 5 to 10 minutes so that it can start to break down the urine.

Step 7 – Scrub with brush

Scrub the location with a scrub brush. Make sure to get into all of the nooks and crannies and that it is soaking wet.

The ammonia solution will now begin to dissolve the urine, which is essential for it to work. It’s crucial to leave it to sit for at least an hour in order for it to do its job effectively

Step 8 – Boils some more water

Once again, boil some water and pour it over the affected area.

Step 9 – Let it sit for 5 minutes

After you have poured the hot water over the area, let it sit for 5 minutes.

Step 10 – Vacuum up

Vacuum up the mixture and debris with a wet and dry vac.

Step 11 – Boil the kettle add more hot water to the area

Repeat the above steps one more time.

Step 12 – Leave for at least 24hrs

After you’ve completed all of the preceding activities, allow at least 24 hours for the enzymatic cleaner to break down the urine and eliminate the odor.

Step 13 – Use Stain and Odor Eliminator (Can be purchased on Amazon)

Spray this over the area to help keep the urine odor at bay.

Note: If the area is large, then remove the spray nozzle and pour it onto the surface from the bottle.

This is a very effective and strong odor eliminator.

When you’ve completed all of the procedures, your patio or driveway should be odor-free and free of urine. If the stench persists, repeat the process until it has gone.

That’s it! You have now successfully cleaned cat urine from your patio or driveway.

Step 2: Pour some hydrogen peroxide onto the stain and let it sit for a few minutes.

Step 3: Scrub the area with a brush.

Step 4: Rinse the area with water and let it dry.

If the stain is still there after following these steps, then repeat them until it’s gone.

To remove old, set-in pet stains from concrete:

Step 1: Mix 1 part ammonia with 3 parts water in a bucket.

Step 2: Pour the mixture over the stain and let it sit for a few minutes.

Why Does Your Cat Pee On Concrete?

This is usually a feature of older cats that can’t seem to control it anymore. They may pee on concrete because going all the way outside is more difficult for them, or they may do it as a sign of dominance.

There are a few things that you can do to help stop your cat from peeing on concrete:

  • Make sure you take them for regular walks and bathroom breaks.
  • If you catch them in the act, say “no” and immediately take them outside to pee.
  • If your cat is peeing inside because they can’t hold it anymore, you might want to consider getting them a potty patch or training them to use a litter box.
  • If your cat is peeing on concrete to mark its territory, you might want to try obedience training to help stop this behavior.

Does Cat Pee Stain Concrete?

Yes, cat pee will leave a mark on concrete. Because concrete is permeable, it will absorb the urine and subsequently acquire a yellowish or brownish tint. However, if you can address it right away, you should be able to remove the stain easily.

How Long Before Cats Can Walk On Concrete

It’s better to give it a full day. The concrete will dry out more effectively this way. If you can’t wait 24 hours, at the very least wait until the concrete has dried completely.

FAQs

Can I Use My Usual Household Cleaning Products?

No, you can’t use your regular household cleaning products since they lack the necessary substance, which is ammonia. Ammonia is what helps to break down and remove the odor of urine.

Can I Use a Steam Cleaner?

No, you cannot use a steam cleaner because it will only push the urine further into the concrete and will make the odor worse.

Can I Stop My Cat Urinating On The Concrete?

There are a few techniques for trying to stop your cat from urinating on concrete, but there is no one-size-fits-all solution.
You might have to experiment with a few different things until you find what works for your cat.
You can try and use a motion-activated sprinkler to startle your cat when it tries to pee on the concrete.
Most people use these to deter other cats in their neighborhood and not their own, but this could be a short-term solution until you can get your cat to stop peeing altogether.
If your cat is old and can’t seem to help it, you might have to consider bringing them to a vet and seeing if there is anything that can be done.

My Cat Keeps Peeing on the Same Spot, What Can I Do?

If your cat is continuing to pee in the same spot, you might want to consider placing a litter box in that area.
This will help your cat know that this is an acceptable place to pee. If you’re having trouble getting your cat to use the litter box, try training them with some positive reinforcement.
Direct them during house training.
Spray the area with vinegar.
Remove their mark.
Sprinkle on citronella.
Create a barrier.
Spice it up with cayenne pepper or chili powder.
Grow plants that cats don’t like.
Keep it clean.

Will bleach get rid of the cat urine smell on concrete?
