Wool clothing that has been improperly maintained are likely to develop a musty odor. These odors are only unpleasant, but they are also a sign of mildew or mold presence. In that case you have to take immediate actions to remove a musty odor from a wool coat to prevent mildew or mold from spreading throughout your closet and home. If the odor is still there after airing the coat out, eliminating the musty odor can be done through basic home laundering -- unless the coat is labeled dry clean only.
