Key takeaway
Wash the removable fabric, treat the padding beneath the rest. The residue is the smell.
Pet urine in fabric splits into two cases: what you can wash, and what you can’t. The washable fabric is easy; the upholstery and padding beneath is where the persistent smell lives.
What causes it
Urine soaks into fabric and the padding beneath it. Removable covers and throws can be washed; the padding and non-removable upholstery hold the residue that keeps releasing odor.
Why it persists
The smell persists in the padding and the non-removable fabric. Washing the cover helps, but the residue in the cushioning keeps releasing odor until it’s treated.
What actually helps
- Wash removable fabric on the hottest safe setting
- Treat non-removable upholstery and padding with an enzymatic product
- Dry everything fully
- Repeat for stubborn residue
How to handle it
- Remove and wash washable covers and throws
- Apply an enzymatic treatment to non-removable fabric and padding
- Let it work and dry fully
- Re-check — repeat for stubborn residue
Common mistakes
- Washing the cover while the padding holds the urine
- Not drying the fabric fully
- Using a regular cleaner that doesn’t act on the residue
