I have a safe (Okay, really a RSC) just for my safe-breaking tools. I just hope I never lose the key.You have extra room in your safe?if you have any power/air tools in your garage, lock them in the safe with your guns, so they can't be used to break in.
A goldenrod doesn't remove water, rather it adds a little heat, hopefully keeping the guns above the dew point. Good enough in a basement that's otherwise kept around 55% and 55F, but not protection enough for a garage in NE.I use the rechargeable dehumidifiers inside my safe which work great but if it's really humid in your basement, it's only a matter of time before they fill up with moisture and you have to charge/dry them out again. But I don't have any experience with the goldenrod/dehumidifier rods in safes. You should be fine if you're running a dehumidifier in the basement which is what I do. I try to keep it at 55% so it's not running constantly.
