Key takeaway
Urine in a couch lives in the cushion and padding. Treat deep enough to reach it, then dry fully.
Pet urine on a couch soaks past the fabric into the cushion and padding — and that’s where the smell stays. Removing it means treating deep enough to reach the residue.
What causes it
Urine soaks through the couch fabric into the cushion and padding. The surface fabric holds some residue, but the cushioning below holds the bulk — and keeps releasing the odor.
Why it persists
The smell persists because the padding is enclosed and slow to dry. A surface spray doesn’t reach it. The cushioning keeps releasing odor, especially when someone sits and compresses it.
What actually helps
- Treat the spot with an enzymatic product that reaches the padding
- Wash removable cushion covers
- Dry the piece fully — padding takes a day or more
- Repeat for stubborn residue
How to handle it
- Remove and wash removable covers
- Apply an enzymatic treatment generously to the spot
- Let it reach the cushion and padding
- Dry the couch fully
- Re-check — repeat if needed
Common mistakes
- Treating the surface while the padding holds the urine
- Not drying the couch fully
- Using a regular cleaner that doesn’t act on the residue
