Key takeaway
Wash the removable fabric, treat the padding beneath the rest. The residue is the smell.
Fabric is the biggest pet-odor reservoir category — it holds odor in its fibers and the padding beneath. Removing it splits into washable and non-washable.
What causes it
Pet odor gets into fabric at the fibers (oils, dander) and the padding beneath (accidents and moisture). Removable fabric can be washed; non-removable fabric and padding need treatment.
Why it persists
The smell persists in the padding and the non-removable fabric. Surface cleaning reaches the top; the residue deeper in the material keeps releasing odor.
What actually helps
- Wash removable fabric
- Treat non-removable fabric and padding with an enzymatic product
- Dry fully
- Repeat for stubborn residue
How to handle it
- Wash removable covers and throws
- Apply an enzymatic treatment to non-removable fabric and padding
- Let it work and dry fully
- Re-check and repeat if needed
Common mistakes
- Washing the cover but not the padding
- Not drying fully
- Using a regular cleaner that doesn’t act on the residue
