If the cushions are color safe, use a water-bleach bath to kill the mold, rinse thoroughly, then allow to dry. Multiple baths may be required depending on the amount of mold and some physical wiping of the surface may be required. Be sure to do this outside as bleach is noxious. Mixture is 1/2 cup bleach per 1 gallon water.
