Re: Safe/Goldenrod Question
Goldenrods make air move.
If your safe is not air tight, warm air will move out of the top and cool moist air will move it the bottom. A perfect moisture cycle is created. Net drying effect? Zero.
If your safe is airtight, a Goldenrod will warm up any moisture and keep it in suspension in your safe like a rain forest. Net drying effect? Zero.
We do not use golden rods if we have a real humidity issue. We use silica gel and, as importantly a hygrometer.
With a hygrometer in our safes we can see the most important information of all, what the humidity is. We are looking to get the humidty to around 50% at all times and in all temperatures. We clean and dry and oil our weapons when we place them away. Nothing ever goes in wet. Avoid all leathers as well.
Fireproof safes have the additional issue of having water retained in the fireproof lining (that is what "steams out" to cool and protect your possessions....and it is why fireproof safes are for paper...as in money and documents...and will ruin most gun finishes, etc. if the temp triggers the steam out).
So...forget the golden rod. Go with the Silica gel in as big a container, and as many as you need, to dry out a new safe and to achieve approx 50% on your hygrometer and not be driven crazy by the recharging cycles. I charge up three times a year on a large safe. Humidity is approx 45%. High/Lo digital hygrometer tell me everything I need to know. No rust, no issues for decades. Silica Gel is a moisture remover that is what will (with proper cleaning and oiling) keep rust off your weapon.
You will need two (2) of these if your safe is new and fireproof.

30+ years of collection care and high humidity experience talking here. Goldenrod, been there, done that, go silica gel.
