I cleaned my carpet and now it smells like urine, why so? That’s not a problem only you are facing but numerous other homeowners are struggling with this. We understand that once you clean your carpets, it should leave them smelling fresh and inviting but the pungent urine smell afterwards ruins the whole vibe and your mood too.
The reason behind this issue is more common than you imagine especially for pet owners or homes dealing with excessive spills and heavy footfall, but what? It might be the residual microbes or some moisture left behind due to over-wetting during cleaning procedures or something else.
Let’s delve into the reasons behind why the urine smell persists even after cleaning and the most effective solution to eliminate this problem permanently.
I Cleaned My Carpet and Now It Smells Like Urine? How It can be?
The culprits behind the stubborn urine smell that doesn’t go away even after thorough cleaning are residual matter and bacteria. A few main reasons include:
Wrong Cleaning Products
For proper cleaning, you must use the right cleaning products which allows you to get rid of odor for good. Using a cleaning product that isn’t designed specifically to eliminate pet odor or urine can aggravate the problem instead of neutralizing it.
Urine Crystals in Carpet Padding
When a pet accident occurs, the urine penetrates deep into the carpet’s padding and fibers. The surface cleaning might remove the stain efficiently but the moisture might rehydrate the urine crystals within paddings which causes the pet smell to resurface.
Excess Moisture
During cleaning, over-wetting your carpet might lead to tripped moisture which integrates with lingering urine residues and creates a hub for bacteria while increasing the smell.
Bacterial Growth
Urine contains organic compounds which the bacteria rely on for food. Even after cleaning bacteria may persist and cause the smell to resurface once they proliferate.
How to Eliminate Urine Smell from Carpets After Cleaning
Be extra vigilant because you already have cleaned your carpets, so these persistent compounds left behind may need special attention. You can try DIY Solutions or professional cleaning whatever suits best your situation.
- Use an Enzymatic Cleaner
Enzymatic Cleaners are designed specifically to target organic compounds in the urine.
How To Use It: Spray the cleaner sparingly all across the targeted area and allow it to do its action for 10-15 minutes. Blot with a clean cloth and let the area air dry completely.
- Apply Baking Soda for Odor Absorption
Baking soda acts as a natural deodorizer that absorbs lingering stench caused either due to spills or pet accidents.

How To Use It: Sprinkle baking soda powder over the carpet and let it sit overnight. Vacuum thoroughly the next day for proper cleaning and fresh home.
