Silicon bag absorbs moisture, but you need a rechargable one. This thing saturates after absorbing certain amount of moisture. In long term gun storage context, there are two options: (1) you drives the moisture out of them; or (2) you throw it away and put a new bag in.

Rechargable means option (1). You put saturated silicon package into oven of 350F for a few hours and silicon will be dry again and its moisture absorbing function is restored. Regular silicon bag is not chargable because the bag is paper made.

Silicon in paper bag is an excellent choice for manufacturer of shoes, self-assembly furniture box, etc. Low cost, one time usage, good enough.

The above dehumidifier.com products are nothing more than silicon. Silicon color changes from blue (dry) to pink (wet) so you know when it's saturated. The ones hold in aluminum container is rechargable. There are at least two packaging forms.

I still run against BreakFree (tm). It does not effect gun blue, but that's only part of the story. No effective way to prevent it flowing to the wood grip panels. It's liquid, what would you expect. For gun cleaning, it's an excellent choice, but for gun storage, I reserve my concerns.
