I have a couple questions about storing guns in cold temp. My safe is lagged into the concrete in my garage. I realize the cold itself won't have any impact on the guns, but will the cold have any effect on how my dehydrator works in the safe? (I have one of the tubular/plug in deals.)

Also what do yall do if you need to bring one in the house for cleaning or tinkering? I have been putting them in a well padded case and then bringing them in so they warm up slowly and don't sweat. How do yall handle this?
