Bought product to keep ahead of ice buildup. During recent severe cold snap, pre-treated concrete steps and sidewalk area. Kept ice from forming. Only problem is it stayed damp so snow formed over area. Was easy to clear off later though.
This product worked just as well as the magnesium chloride products we have used before. I helps as a pre-treatment, but is by no means any different than many other de-icers out there.
