Short answer
Magnesium chloride pellets melt to about -13°F and are less aggressive on concrete, plants and pets than rock salt or calcium chloride.
Magnesium chloride is the choice where damage risk matters more than raw cost: newer concrete, pavers, planted edges, and residential walks where dogs cross.
It still melts hard — down to roughly -13°F — while running less corrosive than sodium or calcium chloride.
