Heavy rains recently flooded our basement, and however the water got in, it told its friends. Comparatively modest rain has continued to get in, creating an almost chronically wet floor. We have a dehumidifier and two fans going but the air is dank.
I have a "Goldenrod" and some "Super VCI plugs" in the safe. These are marginal to begin with, but I haven't had this problem before.
I doubt either one can deal with the air exchange that takes place when opening the door.
I'm half tempted to spray everything with LPS2. Just kidding. Maybe.
Perhaps a couple pounds of absorbent packs?
It's not that I have a large collection, but I don't know of anyone nearby who could take what I have for a while. One is a Class III weapon and can't go anyway.
