Mildew is a type of fungus that can grow on clothes, leaving behind an unpleasant smell. Mildew can grow in damp, humid environments, such as in a closet or bathroom. If you have clothes that have developed a mildew smell, there are a few things you can do to get rid of it.
The first step is to identify the source of the moisture that is causing the mildew to grow. Once you have identified the source, you can take steps to eliminate it. For example, if the mildew is growing in your closet, you may need to dehumidify the closet or open a window to allow air to circulate.
