Before diving into the cleaning process, it’s important to understand why urine can leave such a persistent smell. Urine contains urea, ammonia, and other compounds that break down into odorous substances. When it soaks into your couch, it can penetrate the fabric and even the padding underneath, making it difficult to remove.

The first step in addressing a urine smell is to act quickly. The sooner you can treat the affected area, the better your chances of removing the odor.

Blot the Area: 

Use paper towels or a clean cloth to blot the stain. Avoid rubbing, as this can spread the urine further into the fabric. Press down gently to absorb as much liquid as possible.

Cold Water Rinse:

If the couch fabric is water-safe, dampen a cloth with cold water and blot the area again. This can help dilute the urine and lift some of the odor-causing substances.

After the initial treatment, it’s time to apply a cleaning solution. Here are several options:

Vinegar Solution: 

Mix one part white vinegar with one part water. Vinegar is a natural deodorizer and can neutralize the smell of urine. Spray the solution on the affected area, let it sit for 5–10 minutes, and then blot it up with a clean cloth.

Baking Soda:

Once the vinegar solution is blotted up, sprinkle baking soda generously over the area. Baking soda is known for its odor-absorbing properties. Let it sit for several hours or overnight to absorb any remaining smells.

Commercial Enzyme Cleaner: 

If the smell persists, consider using a commercial enzyme cleaner specifically designed for pet urine. These cleaners break down the odor-causing compounds in urine. Follow the manufacturer's instructions for application.

If the smell remains after initial treatments, you may need to do a more thorough cleaning.

Steam Cleaning: 

If your couch is suitable for steam cleaning, this method can be effective. The heat and moisture help to lift odors and dirt from the fabric. Ensure that the couch is completely dry afterward to prevent mildew.

Upholstery Cleaner:

 
Use a store-bought upholstery cleaner according to the instructions. Test a small, inconspicuous area first to ensure it doesn't damage the fabric.

After cleaning, drying the area thoroughly is crucial. Moisture can lead to mold growth and more unpleasant odors.

Use Fans:

Position fans near the cleaned area to promote airflow. This helps speed up the drying process.

Sunlight Exposure:

If possible, place the couch in a sunny spot. Sunlight can help eliminate odors naturally and speed up drying.

Once you’ve successfully removed the urine smell, consider implementing some preventative measures:

Couch Covers:

Invest in removable and washable couch covers, especially if you have pets or young children. This makes cleaning much easier.

Regular Cleaning:

Establish a routine for cleaning your couch. Regular vacuuming and spot cleaning can help prevent odors from becoming ingrained.

Pet Training:

If pets are the source of the urine, consider training them to avoid the couch. Positive reinforcement techniques can be effective.

Urine Deterrents:

For pets, there are sprays available that can deter them from returning to the same spot.

If you’ve tried all the methods and the odor persists, it may be time to consult a professional cleaning service. Professionals have specialized equipment and cleaning solutions that can effectively eliminate tough odors and stains.
