Why Is Pee Smell So Hard to Remove from a Couch?
What Is in Urine That Causes the Lingering Smell?
Do you wonder why that pee smell will not go away? The main reason is uric acid. Pee has many parts, but uric acid crystals are the real problem. When the water in pee dries up, these sharp crystals are left behind. They do not dissolve in water.
When you clean the spot with just soap and water, you may get the stain out. But the uric acid crystals stay. When these crystals get wet again, they let out that bad ammonia smell. This is why the smell can go away and then come back on a wet day.
How Does the Smell Get Trapped in Couch Cushions?
Your couch is like a big sponge. The cloth, stuffing, and foam are all full of tiny holes. When an accident happens, the pee does not just stay on top. It soaks deep down into the cushion.
This makes it very hard to clean all of it. You might clean the top cloth. But the pee deep inside the foam will still make a bad smell. To really get rid of the smell, you have to clean the spot you see and everything under it.

Why Is Blotting, Not Rubbing, So Important?
When you find a new wet spot, you may want to scrub it hard. But this is one of the worst things you can do. Rubbing the stain will only spread the pee. It also pushes the pee deeper into the couch. This makes the problem much worse.
The right way is to blot. Get a lot of paper towels or a clean, thick white cloth. Press down hard on the wet spot. This will soak up as much pee as you can. Lift the cloth, use a dry part, and do it again. Keep doing this until no more pee comes out.
Should You Use Hot or Cold Water on a Fresh Pee Stain?
Always use cold water. Many people think hot water cleans better. But for stains like pee, heat is bad. Hot water can cook the proteins in the pee. This can make them stick to the cloth. This can set the stain and the smell so they never come out.
After you blot up the extra pee, you can wet a clean cloth with cold water. Keep blotting the spot. This helps thin out the pee that is left. It does not set the stain.

This home-made mix is a favorite for a good reason. It is a strong, natural, and safe way to fight pee smells on most couches.
Why Is This DIY Combination So Effective?
White vinegar is a weak acid. This acid is great for breaking down the uric acid crystals from the pee. The vinegar kills the source of the smell.
Baking soda is a great natural smell soaker. After the vinegar breaks down the uric acid, the baking soda soaks up any smells left in the cloth. They work together as a strong team to fight pee smell.
What Is the Vinegar and Baking Soda Method for How to Get Pee Smell Out of Couch?
- Blot the Area: First, blot the spot very well with paper towels. Get up as much fresh pee as you can.

- Let It Dry Completely: Now, you must wait. Let the baking soda sit until it is all dry. This can take a few hours or all night. As it dries, it will pull the last of the wetness and smell out of the couch.

What Is the Hydrogen Peroxide, Baking Soda, and Dish Soap Recipe?
This recipe is a strong stain and smell remover.

- Spray and Work It In: Lightly spray the mix on the stain. Use your fingers or a soft brush to gently work it into the cloth.

How to Get Pee Smell Out of Couch Using Enzymatic Cleaners?
For the hardest jobs, like pet pee, an enzyme cleaner is the best choice. These are the cleaners that pro cleaners often use.
What Are Enzymatic Cleaners and How Do They Work for How to Get Pee Smell Out of Couch?
Enzyme cleaners are not like normal soaps. They have special, natural enzymes. These enzymes are made to break down and eat the stuff in stains like pee. Instead of just cleaning the stain, they eat the uric acid crystals. This gets rid of the source of the smell for good. This is why they are so good for pet accidents. For more tips on pet care, The Humane Society of the United States has great advice.
How Do You Properly Use an Enzyme Cleaner on Your Couch?
- Read the Directions: Each brand of enzyme cleaner is a little different. It is very important to read and follow the directions.
- Test in a Hidden Area: Like with any cleaner, test it on a small, hidden spot first. This is to make sure it is safe for your couch.
- Saturate the Area: The key to making an enzyme cleaner work is to use a lot of it. You must make the stained spot very wet. Make sure the cleaner soaks as deep as the pee did. This lets the enzymes get to all of the uric acid.
- Let It Air Dry: Do not blot or dry the spot after you put the cleaner on. The enzymes need time and wetness to work. You need to let the spot air dry on its own. This can take a day or two.
- Keep Pets Away: Keep pets and kids away from the spot until it is all dry.
