Simply place a Desiccating Container together with the item that is to be protected in a tightly closed or sealed moisture resistant container.

It will absorb up to 34% of its own weight in water vapor.
Silica gel beads are orange in color when active (dry). The gel beads will gradually change color from orange to green as they absorb moisture. Once the gel beads turn green, they are no longer active and must be heated to remove the accumulated moisture using a conventional oven at 250° F for 3 hours. Avoid overheating while drying. When the color of the gel beads returns to orange, the container is ready to be reused.
