Removing mold / mildew from machine-washable items
If garments are still wet, lay in the sun to dry. Dry heat and light help to kill mold. If your item is labeled dry clean only, take it to a cleaner after it is dry.
If your item is washable, fill washing machine with warm water and regular amount of detergent. Add ½ cup Borax and let mildewed garments soak in this solution for up to four hours.
Run regular wash cycle.
If garments still show signs of mildew, do not put in dryer. Apply a mixture of lemon juice and salt to mildew spots and dry in sunlight.
