Dessicant cartridge shelf life
Am I correct in assuming that installing a two year old dessicant cartridge that has been in my garage exposed to Virginia's humidity is an exercise in futility?

Even if open, depending on the container you can dry them back out in the oven on low. We have even emptied the blue color changing desiccant used in air driers on isolated mountaintop sites onto foil and dry it in the sun. Takes less than 20min on a nice day.
