Can you also microwave them in a bowl of water to reset them? I have 2, but boiling has kind of become a hassle. Can you also microwave them in a bowl of water to reset them?

Maybe they've changed somewhat since i had mine. If you look up toward the top, it's been about ten years since i've used mine. I seem to remember trying to simply soak them in hot water and it not working; i actually had to keep mine at a low boil. Air pressure will also affect boiling points, though...boiling at one elevation might just be really hot water at another. Eh. Maybe they’ve changed somewhat since i had mine.

The temperature of a bowl of hot water won't be adequate; the sodium acetate requires sustained temperature at above the boiling point of water in order to become stable in a fluid state. Wrap one in a towel, and boil a pot of water. Drop the wrapped warmer in after the water's boiling, and let it boil for 10-15 minutes. Mellimaus:
