Ann - try the following. If that doesn't work, I'm not sure. I have also heard of a light bleach solution instead of alcohol. Good Luck!
Mix 1 cup of rubbing alcohol with 1 cup of warm water in a bowl. Dip a cloth into the solution, and squeeze out the excess liquid.
Scrub the mildew stains with the wet cloth in a circular motion.
Rinse the areas with a sponge dampened in water once the stains are removed.
Dry the mattress outside in direct sunlight for several hours; otherwise, use fans to dry the mattress completely. Sunlight helps to remove odors in the mattress.
Spray a disinfectant evenly over the entire mattress to kill any remaining spores. Do not saturate the mattress in disinfectant spray. Allow the mattress to dry completely before replacing the bedding.
