How to Get Urine Out of Concrete
Normally my dogs are good about going in the yard, but we’ve been watching the in-law’s dog for a few weeks and he’s a little less courteous, and has been marking the concrete walk way to our front door.
To make matters worse, he is on a special diet and daily medication for a prostate issue that has urine smelling like a bottle of ammonia mixed with asparagus and pickle juice – unpleasant.
Long story short, it’s time to go over how to get urine out of concrete.
Getting Set Up
Once urine has soaked into concrete, it can be difficult to remove, even with a high pressure hose. Finding the right cleaning product is essential.
When it comes to selecting the right product, enzyme formulas have not worked for me in the past. It’s very difficult to keep the area damp and at a consistent temperature.
What we need is a good surfactant/detergent based cleaner, like Urine Destroyer. These are ideal for this type of application because they get down into the porous concrete and separate the urine from the surface so that it can be washed away.
Removing Urine Stains from Concrete
Step 1: Saturate the stain
Apply a liberal amount of product directly to the stain, as well as the surrounding area – a six-inch perimeter is a good rule of thumb.
Step 2: Let it soak into the surface
I usually wait a couple minutes, or as long as it takes to get a cup of coffee/beer/vino.
Step 3: Hit it with the hose.
Spray on a jet setting until the water running off the surface is clean and clear.
Step 4: Allow to air dry.
The area will remain dark as the water dries, but after a few hours you should be left with a stain-free patch of concrete.
I’ve found this method very effective.
For older stains or deep-set urine, increase the amount of time you allow the product to soak the area, and use a stiff bristle brush to scrub the surface and agitate the detergent to activate it.
