Mold and mildew love cool, damp, and dark areas. Reduce moisture in the air by setting-up a fan, dehumidifier, or opening a window. Ideally, humidity should be kept below 40% in your house. Hire professionals to remove moldy ceiling tiles, carpet, linoleum, or drywall. These cannot be cleaned and are potentially hazardous to your health. Scrub non-porous hard surfaces, including walls, the insides of drawers, and laminate, concrete, or tile flooring with detergent and warm water. Simmer a stick cinnamon, orange peels, and whole cloves in water on the stove. Remove when the water begins to boil and set on a pot holder in the musty room to cool. You can also tie blends of spices or potpourri in pantyhose and place them next to a heating vent when the furnace is running. Fill a tray or box with cat litter and leave it in places where you store unused clothing, such as closets or an attic, to reduce moisture and remove odors.  Sprays such as "Oust" also help temporarily eliminate musty smells. These are available at most hardware and do-it-yourself stores and can be used to naturally deodorize basements, closets, sheds, and even shoes. Read the instructions provided on the bag. This will tell you the size and number of bags needed per square foot area. Afterward, spread a thin film of coconut oil on window sills or around the edges of windows and doors. This will prevent mold and mustiness returning for several months.  To disinfect surfaces and kill mold, mix 3/4 cup (6 oz.) of bleach with warm water. Wear rubber gloves and use a sponge to wipe-down surfaces. Let it sit for 5 minutes before rinsing with water. Air dry.  Regularly check windows, doors, and walls for mold or mildew spots or if the musty smell returns. Disinfect as needed.
