Step By Step Instructions for Cleaning Cat Urine From A Concrete Floor

Step No 1 : Locate the source of the cat urine odor

Identify the area where the urine is situated first. If you don’t know where the smell is coming from then spray some of our odor removal formula on to the concrete areas and look for white foaming. The formula has a built in urine finding system (foams up white when exposed to urine) so you know where to treat. The image below shows where the urine contamination is located indicated by the white foaming.

Step No 2 : Mix up a gallon of our formulation

Simply mix the ingredients together in a plastic bucket or plastic garden watering can using formula two

Step No 3: Treat the area with formula two.

Once you have found the contamination pour about 5 pints of the solution onto the areas. You can find the formula on our information page.
Leave the chemical to soak in for 5 to 10 minutes so it has a chance to penetrate into the porous concrete.
You will notice more white foaming at this stage which is the chemical working on the urine residues and this is totally normal. The chemical will start to break down the urine residues so they are able to be removed easily as shown in the next step.

Step No 4 : Check progress of removing the cat urine odor.

Once the chemical stops foaming (can take longer tup to 30 minutes or longer depending on how severe the contamination is) the chemical has burnt itself out, so simply mop up with old rags or towels or use a wet vac and you are done.
Give it the sniff test. If there is still strong odor repeat the process.

That is how to remove cat urine from your concrete. So easy and so fast and 100% guaranteed to work.
