Unspecified spray, plastic bag, and vacuum on a sofa cushion
Rex says

"Mist the cushion, bag it, then use a vacuum hose to draw out moisture."
The science
-
Suction is not drying
A household vacuum empties air from the bag; it does not reliably extract water held inside cushion foam. EPA specifies a water-extraction vacuum for wet upholstery, followed by airflow or dehumidification.
-
The bag holds moisture in
Sealing damp upholstery blocks the airflow needed to dry it. EPA warns that complete drying can be difficult within 48 hours, when mold risk rises.
-
The spray is unknown
Neither the spray nor cushion fabric is identified, so staining, residue, and material compatibility cannot be assessed.
Do this instead
Dry-vacuum loose soil. For a spill, follow the upholstery care tag; use appropriate water extraction only if the fabric permits it, then expose the cushion to airflow and confirm it dries fully.

"EPA recommends water-extraction vacuuming and active drying for wet upholstered furniture; drying completely within 48 hours can be difficult."
