And the best part is, desiccants are 100% reusable! Desiccants absorb moisture, so after a while they stop being as effective.
How much moisture does silica gel absorb?
Silica gel is a form of silica that’s processed into various forms like granules or beads. Silica gel works like a sponge, drawing moisture into its many pores. It has the power to absorb up to 40% of its weight in water.

What is the most effective desiccant?
Molecular sieve is the best desiccant based on technical performance characteristics. Its ability to adsorb moisture, in this case water vapor, is so pronounced that it can remove trapped H20 molecules from a fully saturated silica gel bead, which in turn changes the silica gel back to its original Cobalt blue color.
How do you dry desiccant?
Heat packets at exactly 245-degrees Fahrenheit for 24 hours. Use an oven thermometer to ensure the temperature does not go over 300-degrees for the free-flowing, or over 245-degrees for the packets. For the color-changing silica gel, heat it at 900 watts in three-minute bursts in the microwave until it turns blue.
