mold; mildew.
Even when mold's characteristic black spots have not yet developed, mold spores may be present in cloth. When a person wears
a garment with such spores, his body heat will cause the mold spores present to be noticed by the sour odor given off by the
garment. The cure for such a problem is to soak the garment in a mild solution of bleach, and to not store clothes long before
wearing and rewashing.
