DIY Salt Dehumidifier Humidity can cause excess mold in basements, garages, barns and attics. It can also cause stains and fungus growth on stored items like food, clothing and antiques. Dehumidifiers pull the moisture out of the air and create a dry, cool atmosphere. Though commercial dehumidifiers can be noisy and pricey, you can create a simple dehumidifier at home with salt.
A bundle of chalk hung in a closet will absorb extra moisture and keep clothing fresh and dry, and takes up much less room than an electric dehumidifier. Mount a hook in the closet, out of the way of clothes or linens. Fasten a rubber band around a dozen pieces of chalk, and cover band with ribbon, allowing enough loop to hang chalk.
