RIchard. Those are the two deicers we used extensively here. We only resorted to regular salt when we had run out of everything else. Those two above mentioned product were suppose to not be as corrosive as reg salt. I always had my doubts. Mag chloride imho was better of two for deicing. Probably too expensive to use in your environs. Thats why salt is popular

And yet it irks me the poor dappled fools,
Being native burghers of this desert city,
Should in their own confines with forked heads
Have their round haunches gored."
