I mean… dry from… water. And often enough that I have many bags of silica packets that I reuse. Obviously.
edit: I spend a lot of time outdoors. My gear tends to suffer if I use it and then don’t dry it before I put it away. I dont enjoy taking out some gear to use only to find it corroded or molded. Silica helps that. And for my needs, it is cheaper to reuse silica packs than it is to buy and run a(nother) dehumidifier.
