Pet urine can leave behind a strong ammonia smell that can be difficult to remove. This smell is caused by the breakdown of urea, a waste product that is found in pet urine, by bacteria. There are a number of things you can do to get rid of the ammonia smell from pet urine, including:

How to Get Rid of Ammonia Smell from Pet Urine

Blot up the urine as soon as possible

The sooner you blot up the urine, the less time it will have to soak into your carpet or flooring and the easier it will be to remove the smell.
To blot up the urine, use a clean, dry cloth or paper towel. Do not rub the urine, as this will only spread it around.
Once you have blotted up as much of the urine as possible, rinse the area with cold water. This will help to remove any remaining urine and prevent the smell from setting in.

Use an enzymatic cleaner

Enzymatic cleaners contain live bacteria that break down the urea in pet urine, which is what causes the smell. To use an enzymatic cleaner, follow the instructions on the product label.
Be sure to soak the area with the cleaner and allow it to sit for the recommended amount of time. Once the cleaning time is complete, blot up the cleaner and rinse the area with cold water.
Repeat the process if necessary until the smell is gone.

Use a vinegar solution

Vinegar is a natural deodorizer that can help to remove the smell of pet urine.
To use a vinegar solution, mix equal parts vinegar and water in a spray bottle.
Spray the solution onto the area where the pet urinated and allow it to sit for 15-20 minutes.
Blot up the solution and rinse the area with cold water. Repeat the process if necessary until the smell is gone.
Note: Vinegar can damage some surfaces, so be sure to test it in an inconspicuous area before using it on the entire area.

Use baking soda

Baking soda is another natural deodorizer that can help to remove the smell of pet urine. To use baking soda, sprinkle it liberally over the area where the pet urinated.
Allow the baking soda to sit for at least 8 hours, or overnight. Vacuum up the baking soda and rinse the area with cold water.
Repeat the process if necessary until the smell is gone.

If you are unable to remove the ammonia smell from pet urine on your own, you may need to hire a professional cleaning company.
