Key takeaway
Curtains pick up ambient odor — wash what you can, steam or treat the rest.
Curtains pick up pet odor from the air — they hang in the room and adsorb the ambient smell — plus any direct contact from a pet that brushes or rubs against them.
What causes it
Curtains hold pet odor two ways. They adsorb ambient odor from the air — they’re a large fabric surface hanging in the room. And they pick up odor from direct contact — a pet that brushes against them.
Why it persists
The smell persists because curtains are large fabric surfaces that hold ambient odor, and they’re rarely washed. A curtain can hold a room’s pet smell even after the source is addressed.
