With my gun safe, I use a Golden Rod "dehumidifier" and a desicant pack. Never a rust problem and I am not real good about cleaning my shooter guns. The dehumidifier is not a true take the moisture out of the air type, rather it works as a heating element, keeping the safe interior just a few degrees warmer than the exterior inhibiting condensation. Cheap, worry free and works for me.
