Routine recharging is required. As moisture is absorbed by the desiccant, the indicator will change from blue to light pink, or from orange to pale, depending on the desiccant. A light pink or pale orange color signals that the desiccant can no longer absorb moisture. Proper function can be restored by placing the metal desiccant can in an oven for 2 hours or more at a temperature of 225°F-300°F. The color will change back to blue or bright orange. Repeat as necessary.
The metal canister will be hot when it is removed from the oven, so caution should be used to avoid burns. Allow the can to cool before it is placed in Dry & Store. Best results will occur if the can is covered during the cooling period; a drinking glass or pan lid works well.
WARNING: Use care when removing the metal desiccant can from the oven. Allow it to cool before handling. Never place metal in a microwave oven!
The frequency of metal can desiccant recharging will vary according to several factors, such as season, geographic location, local climate/weather conditions, and the activity/perspiration level of the user.
Check the color of the desiccant crystals before each use, and recharge as needed. Do not operate Dry & Store without a properly positioned desiccant.
