Silica gel can be used to protect your valuables against moisture related damage by lowering humidity within sealed spaces, and preventing the formation of mold, mildew and rust.

This orange silica gel is self-indicating, meaning the beads will change color based on how much moisture they’ve adsorbed; when the beads are dry, they appear orange in color, and when they’ve adsorbed approximately 35% of their total adsorption capacity, the beads will begin turning clear. This allows users to visually confirm when their silica gel needs to be replaced or reactivated – unlimited reactivation cycles are possible. See reactivation instructions below.

Silica gel can prevent moisture damage to electrical goods and electronic components (internally and externally), scientific and optical instruments, communication equipment, metallic parts, leather goods, tools and many other small to medium sized items in use, storage or transit.

Once the orange silica gel has turned clear and is no longer adsorbing moisture, it can be reactivated by heating the beads in an oven at 220° to 250°F for approximately 2-3 hours, or until beads return to their original color, orange.
