Cats are an incredible gift to mankind and some of them have become the biggest celebrities on the internet – like Tardar Sauce, who’s more commonly known as Grumpy Cat. No matter how adorable and lovable they are, cats are still animals and as such, they are prone to ‘accidents’.

If your cat decides that she doesn’t want to ‘go’ in the litter box, you will have a hard time dealing with the mess they make, especially if they pee on a concrete floor. Concrete is a durable and hard material but it is porous and easily absorbs stains. So, cleaning cat urine from concrete floor can be hard but not impossible. Below we have provided step-by-step instructions on how you can remove cat urine from a concrete floor.

How to Remove Cat Urine from Concrete Floor – Step-by-Step

1. Locate the Urine

The first thing to do is to locate the spots where cat urine might have ended up. Use a UV light or blacklight) to scan the floor for signs of pee. Mark these areas with chalk for reference.

2. Cleaning the Area

Next, you need to scrub the affected area of the concrete floor with common household cleaning supplies like Trisodium Phosphate (TSP), vinegar, or hydrogen peroxide.

Trisodium Phosphate is a powerful cleaning solution that can get rid of the toughest of urine stains. This chemical can damage your skin so wear goggles and protective clothing while using it. Add half cup of TSP per gallon of hot water. Apply the resulting mixture to the affected surface. Work a small area at a time because this solution evaporates quickly.

Use a soft, cotton cloth to scrub the pee spot and allow the mixture to sit for five minutes. If it dries any sooner, apply more mixture to the surface. After this, pour hot water onto the affected area of the concrete floor and remove it with a wet vacuum cleaner. Rinse twice again and allow the area to dry overnight.

  • Vinegar

Vinegar is great for skin, but it is also a powerful, natural cleaning agent. Mix two-parts vinegar in one-part hot water to create a diluted solution. Apply it like TSP to clean the affected area. Vinegar is a safer alternative and won’t cause any damage to your skin so use it if you want to steer clear of harmful solutions.

It is worth noting that vinegar can react with the alkaline in the concrete floor, creating unwanted patterns. So before applying it on the stained surface, test it on a small area.

  • Hydrogen Peroxide

Hydrogen peroxide is quite effective in cleaning cat urine from concrete floor. Create a solution by adding two teaspoonfuls of baking soda and two drops of Dawn dish soap to two cups of hydrogen peroxide in a glass. Stir it until the baking soda dissolves completely. Spray the mixture on the areas where you found urine. The sitting mixture will work into the concrete, eliminating traces of cat urine as it soaks. Repeat this process every day for at least three days to ensure that the urine is dissolved.

3. Treatment of the Urine Stain

Once you have removed the cat urine, the next step is to treat the affected area of the concrete floor with an enzymatic cleaner. Enzymatic cleaners are usually available in a concentrated form and they break down the uric acid to remove the unpleasant odors. Follow the specific mixing instructions of the product as some formulas need to be mixed with a carpet cleaner in addition to water.

Pour a small portion of the enzymatic cleaner onto the urine stain and work in a small area at a time. Allow the solution to stay on the spot for at least 10 minutes before drying so that it soaks in completely. You can use a scrub brush on tougher areas. Allow the area to dry naturally overnight and lay a tarp over it if it is drying too fast. Once all the affected areas of the concrete floor have been treated and dry, you can move to the final step.

4. Prevention

In this step, you’ll place a protective covering over the affected area so that the urine doesn’t penetrate the surface if your cat pees there in the future. Using a concrete cleaner, wash the entire floor and allow it to dry for a day. Next, seal any cracks with concrete caulk. After this, apply a concrete sealer on the floor as per the instructions on its label.
