Key takeaway
Upholstery accidents live in the cushioning — treat the padding, wash the covers, dry fully.
A pet accident on upholstery soaks past the fabric into the cushioning — and that’s where the smell stays. The fabric is the easy part; the padding beneath is the reservoir.
What causes it
Urine soaks through the upholstery fabric into the cushioning. The fabric holds some residue, but the padding holds the bulk — enclosed, slow to dry, and releasing odor every time the piece is used.
Why it persists
The smell persists because the cushioning is enclosed and hard to reach. A surface clean touches the fabric; the padding keeps releasing the odor.
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 cushioning
- Dry the piece fully
- Re-check and repeat if needed
Common mistakes
- Treating the fabric while the padding holds the urine
- Not drying the piece fully
- Using a regular cleaner that doesn’t act on the residue
Where PawFresh fits
After the piece is treated and dry, the PawFresh NanoMist Fogger can freshen the room’s ambient air.
