Melts snow ice 4x faster.
Calcium chloride on concrete for ice melt.
While opinions are not always the same most experts agree that calcium chloride is the best product for those seeking an ice melt that is safe for concrete.
The dissolving process is exothermic and generates heat of up to 60 degrees celsius.
This heat quickly melts the ice and snow thus turning it into water.
This is a hygroscopic compound.
Calcium chloride works 4x faster than rock salt by generating exothermic heat that instantly melts even the thickest snow ice with maximum safety and little effort.
Experts agree that calcium chloride is the best ice melt for concrete surfaces.
Being a hygroscopic compound it absorbs moisture and thereafter starts dissolving.
So it absorbs water and then generates heat as it dissolves up to 140 f.
A calcium chloride ice melt melts ice and snow down to temperatures of 25 f safe to use on concrete and vegetation when used correctly.
While potassium chloride is good for the environment it damages the concrete and typically costs 3 5 times more.
Melts down to 25 f.
Another good de icer is cma or calcium magnesium acetate which doesn t wash away as easily as the others and has a lower environmental impact.
No other ice melter out performs calcium chloride pellets.
