What I have here is a couple of ice and snow melters. There's some crazy stuff I wanted to point out to you. This is rock salt, yet the liberal use of the word ice melter, liberal use of the word meaning that ice melters used to a very safe type. But this is rock salt. It will melt snow and ice down to about 20 degrees. The only problem with rock salt is after it melts the snow and the ice, the salty brine solution can soak into the concrete and be pretty doggone corrosive. The ice melter products that are good down to about zero degrees, this is wonderful. It doesn't cause as much spalling, it's not as harsh on concrete, it's very safe on plants. But, what's going on now is that a lot of the ice melter is not just potassium chloride. It's potassium chloride, that's the little white, round balls. It's also mixed with, you got it, rock salt. If you want to get a pure potassium chloride, which I'd recommend for the safety of your concrete, it might run you 24 dollars a bag, but don't be fooled. Some of these ice melters that you think are safe for your concrete, are not. So, before you buy a bag of ice melter, look on the back of the bag, there should be some chemical symbols to find out exactly what's in the bag.
