The source recounts discovering heavily soiled patio cushions after winter storage, including contamination associated with wildlife. It highlights checking removable covers and clearing surface material before ordinary wet cleaning. The condition of the filling also affects whether a cushion can be restored.

Loose grime, removable covers, and filling condition need separate attention.
