Desiccant packs use silica gel to absorb moisture from the air. Silica gel packs are commonly packed with electric appliances and components prior to shipping. Silica gel works but won't prevent rust if there is any standing water droplets on your weapons. When the silica gel pack has become saturated, it changes color, indicating it needs to be dried out. Simply use your kitchen oven to bake the water moisture out of the pack per the manufacturer's instructions and it's ready to use again. The 450 gram silica gel unit protects 33 cubic feet of enclosed space.
