Urine is known as being a difficult odour to remove from floors and fabrics. It has a strong scent, similar to the smell of ammonia, that can permeate a substance and linger for an extended period of time if left untreated. Concrete floors can be particularly challenging since there's nothing to remove that can be thrown into a washing machine. Removing a urine scent from a concrete floor requires some diligence.
Soak up any remaining urine with a rag or paper towel.
Open any doors or windows in the vicinity of the urine stain to help ventilate the room. Airflow will help considerably in getting rid of the smell.
Mix 3 parts warm water with 1 part white vinegar in a spray bottle.
Spray the vinegar-and-water mixture liberally over the area of concrete affected by the urine. White vinegar is a natural deodoriser that will help absorb the urine smell. The vinegar scent will dissipate within a matter of minutes.
Allow the vinegar-and-water solution to dry naturally.
Sprinkle baking soda over the same area and allow it to set for several minutes before vacuuming it or picking it up with a damp towel. The baking soda will help further eliminate the smell.
Sprinkle an enzyme cleaner over the concrete if any scent remains. The cleaner uses enzymes to break up the chemical bonds that make up the urine scent. Clean up the enzyme cleaner in accordance with the instructions on the package.
