That's interesting and a great suggestion.. I totally forgot about this remedy.. It made me think of something else I've used. When I was a kid.. W-A-Y back yonder.. we had a basement. It really got moist down there, especially in the winter. My dad had a rubber compositioned tub. Over that tub hung a screen thingie that held a chemical compound called, as I remember, calcium chloride... a very hydroscopic material. It would suck the moisture out of the air and the excess moisture would drip in the tub to later be tossed. I guess this could be recycled by placing in the sun in the summer to evaporate the water bringing you back to the calcium chloride crystals.
That said.. I remember going into Camping World (and I've seen it at other places)like drugstores.. it appears this company has modified their packaging but still essentially the same process. A great way to go.. essentially non toxic.. unless you drink it.. won't harm the stainless as it stays self contained.
