I live in the mid-atlantic region in USA, where we get the regular change of seasons, and our winters are frequently around 30F (-1C). When it snows, we use rock salt to melt the ice on the sidewalks and roads. However, most rock salt that you would buy at Home Depot/Lowe’s says it works on temperatures as low as 5F (-15C).
So I must beg the question: In areas such as the Great Lakes region or Canada, where winters frequently are below this 5F (-15C) threshold, what do you use to melt the ice if rock salt doesn’t work at these temperatures?
