Spray a generous supply of the bacterial enzyme solution directly on the fabric. For deeper penetration, work the bacterial enzyme solution in with your hands so that in is squeezed into the fabric.
If the contamination is on a cushion or mattress then injecting is recommended.
For blankets, sheets, drapes, sleeping bags and clothes, spray both inside and out generously with bacterial enzyme solution, let sit for 24 hours and wash normally. Sleeping bags might need two treatments.
