This is used on boats to control musty odors, and in libraries to control outbreaks of mildew. There are several convenient sources of small amounts of chlorine dioxide that are sold for use in boats and closets. Apply the liquid to the moldy area and allow it to air-dry. If you can’t find chlorine dioxide in your local hardware store, order it online. Mix the solution by adding 3 teaspoons (0.5 oz.)  hydrogen peroxide to 5 teaspoons (0.83 oz.) of water. Use a thick paintbrush to brush onto the affected area. Test the solution first in a non-visible part of carpet as hydrogen peroxide can bleach or fade colors. Coat the surface of a dry carpet with baking soda, then work into the carpet fibers with a damp sponge mop. Let it sit until it’s completely dry and then vacuum it up.  You may have to vacuum the carpet twice, and move the vacuum in opposite directions.  You can also have your carpets professionally shampooed, or rent a do-it-yourself shampooer from a grocery or hardware store. Clean small throw rugs or doormats in a washing machine. Check the manufacturer's label for cleaning instructions first. Leave an open box of baking soda in your cupboard or trunk to remove odor and absorb moisture. Let it stand for at least 2-3 days before removing.  You can also wipe cupboard, trunk, or drawer surfaces with a 50-50 solution of baking soda and water, then add a liner to keep the area clean. A small opened can or container of fresh coffee grounds can also be effective in small spaces. Leave it for 2-3 days before removing or replacing. Alternatively, remove all items from the storage space and sprinkle a thin layer of coffee grounds or baking soda on the floor of the surface. Let sit for 2-3 days and then vacuum it up or wipe it with a damp cloth. Leave it open and let it air dry.
