Silica gel is used as a desiccant, an odorless substance that naturally absorbs moisture to keep our purchases from spoiling, molding or degrading due to humidity.
Defogger Extraordinaire: Safety first! Place some silica gel packets on the dashboard of your car to help maintain a clear windshield in times of high humidity. This works just as well in the corners of your windowsills to dissipate condensation. You can also leave a packet in an eyeglass case.
