I didn't find this in the article, so:

You can "recharge" silical gel by baking in the oven at 120 C for a couple of hours. If you do, be careful to remove the casing before you do, unless it is heat safe.

I have a small collection of oven safe dessicant packs that I keep on hand for emergency drying electronics.

This sounds like a great idea, but how do you keep it from being "drained" or hydrated?

Precisely this! Even so, I refresh them just before using them.

TIL about the microwaving trick. I'll have to find out more about it. My concern would be the gel beads popping from internal pressure.
