I think I've asked this question a dozen times, but I'll try again. Last December, I finally got a safe, and a Goldenrod dehumdifier. I also bought a hygrometer to watch the level of humidity in the safe. During the winter months (when the furnace was on) the humidity level was in the mid-twenties. Now that spring/summer has arrived, the level has gone as high as 52%. I've bought some silica gel dessicant, and every other day I bake it in the oven per instructions. The three trays of baked dessicant bring the level down to around 38%. Then it starts back up again. Part of the reason I got the safe was so that I didn't have to keep my guns in the vapor-inhibiting bags (which work 100%; in ten or more years I've never had a moisture problem using them). So, at what level does humidity pose a threat to guns stored in safes? Any replies much appreciated.
