You know the smell, but how do you get rid of it? Removing cat urine smell from concrete can be easy once you know how to do it.
So why does the smell stick around? Concrete is porous and allows the cat urine to seep into it and stay. When you clean, you only get the top layer, and thus the reason why you feel like you can never get rid of the smell.
Through our research, we have come up with some of the best ways to remove cat urine odor from concrete.
The first method we stumbled upon was to grab a bristle brush and some Simple Green and scrub in the Simple Green and water mix.
The goal is to keep the surface wet all the time, as this would allow the simple green to get deep into the pores of the concrete. After scrubbing for several minutes, it was best to go ahead and rinse the area with clean tap water.
The second method we found to work was to use some strong hydrogen peroxide and water mix and let it sit for 30 minutes. After the 30 minutes, you would wipe the area dry and repeat several times.
Sometimes it might be required to let the mix sit overnight. Soaking a rag in the mix and placing it over the concrete spot for a few days would help the mix get deep inside the pores and eat up the cat urine smell.
The last method was to really clean the area and then pick up some latex or oil-based paint to coat the area that has the cat urine smell to it. This would be a last resort since it will change the color of the concrete.
What this method does is coat the odor up forever, and the paint will go down deep and cover the pours too.
