I think I've found our killer use case for the ash from our wood stove: as a moisture absorbent in the barn. We have one of those Tuff Shed barns and the first year I was heartbroken to see so much mold growing on leather and other fabric because it was too damp. (We live in the PNW and it's really dark and wet over the winter.)
The past two years, I've laid out tubs where I pour ash from our wood stove. I think the key is to get a lot of surface area. No mold! I'm so happy.
What other good uses of wood ash have you found?
