The Science Behind Melting Our Snow & Ice

Posted: Updated:

After our weekend warm-up, now is the perfect time to utilize salt on your driveway and sidewalk as the melted snow has re-froze to ice.

A variety of different salts can be found on the market, so what works best in our weather? Dr. Ganesh Bala, a chemistry & biochemistry research scientist at North Dakota State University, recommends a calcium chloride salt over a rock salt.

Noting that with our temperatures in and around Fargo, you'll see better and faster results with a calcium chloride salt.

A rock salt will melt snow and ice but not as well as calcium chloride based products. However, a rock salt won't dissolve like calcium chloride and last longer on your sidewalk or drive, as well as, provide you with better traction.

Even though some calcium chloride products claim to melt ice into subzero temperatures such as   -25, -30, even -50 degrees. Dr. Bala, says it's actually pointless to use salt in those temperatures because any ice that has melted will just re-freeze back into ice.
