What’s in the de-icer?

As of March 2022, grounds has informed us that the following three de-icers are in use. Information has been taken from de-icers’ respective websites.

  • ClearLane De-Icer:  “Made using a patented liquid magnesium chloride formula and mixing process, ClearLane enhanced deicer is a pre-wet sodium chloride product. The formula contains a PNS-approved corrosion inhibitor, a coloring agent, and a leaching inhibitor.”
  • Emperor Melt:  “Dyed blue, an advance ice melt formula enhanced with corrosion inhibitors. The salt is sprayed with liquid magnesium chloride and calcium chloride for fast acting, environmentally friendly ice control.”
  • Ultrapro Ice Melt:  “This Ice Melt is environmentally formulated and made with CMA, which generates heat to quickly melt ice and snow. . . This ice melt also has calcium chloride pellets in it which help melt to lower temperatures and prevent refreezing. It is colored green so you can see where you put it down to reduce over application.”
