Remove pet urine off concrete

So you have a concrete floor, perhaps in your basement or under your carpet in your home that seems to be permanently stained with pet urine, a.k.a dog or cat pee. You can smell or see pet urine stains that no matter how much you bleach or wash with vinegar don’t go away. It’s as if you have to settle with the fact that once dog or cat urine has seeped into concrete, it’s there forever. What’s worse is it seems to give off a permanent urine odor, constantly releasing stringing and offensive fumes. Let’s take a look at how we can remove pet urine from concrete the right way so that you have a clean smelling cement floor again.


Getting that dog or cat urine off your concrete
As you already know, concrete is dry and hard as rock. But it is also quite porous. This means, that anything liquid that comes into contact with bare (unsealed) concrete will saturate concrete. Usually this is harmless, but not when it comes to pet urine. Dog or cat urine can seep deep within concrete; and anyone who has had cats or dogs knows that animal urine can be difficult to get rid of. What’s worse is this potent stuff can lie dormant inside the concrete, only to release its odor when moisture gets back down into the concrete. The fumes will find their way into anyone’s nose who is nearby. Yuck!

You’ve probably discovered you can’t just “clean” off pet urine from concrete. You must get it using a series of steps, each one playing a role in ridding the urine smell from concrete once and for all. Cat urine removal, especially, is not a project to take lightly in most cases! Here are the steps; you’ll be happy to know that cleaning the surface of urine stained concrete is the first one, so if you’ve done this, it wasn’t a waste!

  1. First, thoroughly clean all concrete surfaces with a vinegar/water mix. Since the vinegar is so strong, you can get by with a 2-to-1 mix with water. While you can use a black-light to reveal pet urine spots on your concrete, the best method is to plan to treat the entire surface of the concrete in question so you don’t miss any spots, and also so this treatment will be consistent across your floor.
  2. Secondly, we want to use a special cleaning solution to help you further remove stains and odor from the surface, and just below, of your concrete. This is an enzymatic cleaner recommended by vets and that is safe to use in your home around your family and pets (available here for cats, and also one just for dogs). It works for animals and pets that have gone to the bathroom or sprayed (marking territory), and can also be applied to furniture and carpet. The best way to use this for getting rid of pet urine on concrete is to spray it on thick across the cement surface, more or less soaking the top. You want this to really work its way into the concrete and not evaporate too quickly into the air as it dries. To control the evaporation, lay a large plastic tarp or liner over the sprayed area. This will allow the solution to better penetrate into the urine stained concrete. Allow to dry for as long as it takes, or at least a few hours.
  3. When you’ve cleaned and sanitized the top portions of your concrete as outlined above, and everything is dry, its time to seal your floor. This will essentially seal your concrete against moisture that can get inside and release what may be left of old urine stains. It will also be a great general protection for your floor as well as look a whole lot nicer. Be sure to use concrete sealer with an anti-slip rating. A low-sheen is best as it allows for easy cleaning. The best part is you can choose from endless colors to get your floor looking just how you want. Okay, maybe the best part is your floor will actually smell the way you want (not like urine) as you’ve now cleaned and sealed your concrete floor, thus getting rid of pet urine stains and smells from your concrete forever!

By the way, the Urine Off cleaner comes in smaller (cheaper) sizes too for cats and for dogs.

Dog or Cat Urine in Carpet?
If you have pet urine odor or stains in carpet and have tried the typical solutions (like vinegar, ammonia, rubbing alcohol, etc.), then you should definitely try the enzymatic approach here too — just like with pet odors and stains on concrete. And as with concrete, you need something that will get in and penetrate the fabric (in the case of pet stained carpet), and break down the odor-causing elements of the stain. Urine-off makes a wonderful enzymatic solution that is perfectly safe for you and your pets. Getting this is a very small investment to pay for removing pet odors and urine stains from carpet!

    I just read your article; thanks. After cleaning the concrete, I’d like to have the floor tiled. Sealing the concrete as suggested won’t be possible for this reason. Will any lingering odors work their way through the tiles???
    Thanks.
