Salt has many uses around the house. Besides enhancing baked potatoes, making bland burgers better and coating the rims of margarita glasses, it can be employed in gargling, stain-removal and de-icing the driveway. Historically it’s been used as currency, its taxation financed the building of the Erie Canal, and it’s one of the most effective food preservatives in the world. There’s even a Salt Institute, which is dedicated to spreading the word about salt’s illustrious history and “14,000 uses.” Your grandmother probably knew most of those uses, but she probably didn’t know it could be used to make chlorine for pools.
