Always read and follow the care instructions and any warnings on the garment label. And, follow the General Rules for washable fabric stain removal.
Mildew is a growing organism that must have warmth, darkness, and moisture to survive. Mildew actually eats cellulosic fiber and can also attack manufactured fibers, causing permanent damage and weakening of fibers and fabrics
To treat mildew first carefully brush or shake off mildewed area.
Pretreat the stains by rubbing the areas with a heavy-duty liquid detergent. Then launder in the hottest water safe for the fabric, using bleach safe for fabric. (Chlorine bleach is best if OK for the fabric.) Always check for colorfastness before using bleach.
Let item dry in the sun.
Badly mildewed fabric may be damaged beyond repair. Old stains may respond to flushing with dry cleaning fluid, i.e., Carbona, Energine, Goddard's (Carefully read and follow the instructions on the product label).
