Urine, whether human or animal, has a strong odor that lingers even after absorption into a surface area. Using deodorizing products only mask odors, making the urine smell go away temporarily but over a short time, the smell will return. To effectively remove urine smell from flooring, use an enzymatic cleaner when removing the urine spot. Enzymatic cleaners contain bacteria and natural enzymes that neutralize the smell by eating away at the odor-causing bacteria found in urine.
Find the urine stains and check to see if the stains are new or old. If there is visible urine, wipe it up with paper towels.
Pour an enzymatic cleaner on the stains. Put plastic wrap over the effected area and tape it down. This locks in the cleaner, allowing it to work at getting rid of odor-causing bacteria. Let the solution sit for 24 hours.
Remove the plastic wrap and use paper towels to blot up any remaining moisture. Allow the floor to air dry.
Locate the urine spot. If the spot is damp, use a wet vacuum to suck up the urine.
Saturate the affected area with an enzymatic cleaner. Allow the cleaning solution to remain on the carpet for 5 to 10 minutes, allowing it to work at removing the urine stain and odor causing elements.
Go over the spot with a wet vacuum, removing as much of the cleaning solution and moisture as possible. Allow the carpet to air dry.
