    I was reading the info on one of those de-humidifier bars for safes. Says it heats up to cause air movement.

    So why is this better than say, a small 2 or 3 inch fan? Seems if moving air is the purpose of the bar, the fan would do a much better job of that.

    Bigger brains than mine must have hit on the bar as the preferred method, but just wondeing why.

    I believe that it works along the same lines as a boot dryer. Warm dry air circulates and picks up moisture. It then cools and sinks to where the dehumidifier is. It is then warmed and dried out, causing it to rise again.

    Actually two things are accomplished with golden rods.

    1. the air temperature inside the safe is is raised a few degrees, keeping moisture from condensing on your firearms.
    2. the warm golden rod in the bottom of the safe creates very slight air movement inside the safe keeping air circulating.

    In addition to a small golden road I like to use damprid in my safe. The combination keeps air warm, moving, and any moisture in the air is obsorbed before it can do any damage.

    I have three large safes in my gun/rec room and outside of running a dehumidifier in the corner of the room. I have made and use two simple desiccant dehumidifiers for each safe. First of all I bought a quantity of Indicating Drierite(changes color when abrorbing moisture) and six canning jars with the removable sealing lids and a piece of plastic window or door screening. I simply filled the jars half way with the Drierite, cut a piece of srceening to fit over the jar and attach the jar's open lid. I put two in each safe and when the color changes from blue to red, it's time recharge. An hour in the oven at 250-300 deg F will do the job. This desiccant will never wear out and last close to six months before the need for recharging. I've never had a spot of rust this way.

    I use an 18 inch Golden Rod and a Closet Dehumidifier purchased at Wally-World...And I keep my firearms wiped down with an oily gun rag (old T-shirt saturated with gun oil). I have no rust problems.

    All the Goldenrod does is heat the air a couple degrees above ambient. A light-bulb will do the same thing. It does not reduce the amount of water vapor in the air. Warmer air holds more moisture without it condensing on your firearms.

    I was thinking about getting a Goldenrod for my safe, and also keep my Remington rechargable dehumidifier (the plug in type). I figure the Goldenrod will circulate the air, and the dehumidifier will remove the moisture. My basement is kind of damp, and want to be extra sure!

    I have a gun cabinet in a small walk-in closet. If the humidity gets a bit too high in that closet, I just turn the light on. Leave it that way overnight or for a few days.

    I stuck a humidity meter in there and when I leave the light on overnight it will drop the humidity by about 10%. If I leave it for a few days it will drop it 20%.
