Heres a tip on drying out desiccant. Put it in a microwave safe dish, I use a Corningware 8 frying pan, and then in a microwave. Depending on the power of the oven, it takes about 10 minutes (1250 w oven) to turn the pink desiccant to bright blue. I stir it once during the drying process. Much quicker than using a 250 F oven.
2 year shelf life.
