Snow melting agents?

So as I understand it, Calcium Chloride works better at very low temperatures vs. rock salt. Where does Sodium Chloride fit in?? Got some quotes that state "Soduim Chloride"?? Either easier on asphalt surfaces?? Thanks

Calcium Chloride is safer on asphalt. Sodium Chloride is rock salt. None of it needs to be track indoors on your floor coverings.
Yep, sodium chloride and rock salt are the same.
The calcium chloride produces an exothermic chemical reaction that releases heat, but when the reaction is over, it’s consumed and done. The salt lowers the freezing point of water, so it takes lower temps to ice over. Really, the two complement one another, and can be used together to prevent freezing and then reverse it.
Don't have asphalt, but salt will damage concrete. Don't ask.
Sodium Chloride promotes rapid rusting of automobiles driven on winter roads where it is used. I used to live in an area that was close to a salt mine so the county got salt at a great price. At the first hint of snow they would lay down salt on the pavement so they could delay, or skip, plowing. Cars in that area were very rusted out after only a few years. Replacing a muffler was often an annual event.
Don't know the brand name off hand but, the stuff we use is pet safe, concrete / asphalt safe, lawn / garden safe and good to -20. Sold at the front door of our grocery store.
Calcium Chloride rusts your car
Yes it does. Calcium Chloride is what they use (or used to) to weight fluid fulled tires. It is VERY corrosive.
Yep, for sure. It’s a form of salt.
I worked for several decades at a chemical plant formerly owned by Dow Chemical and now by OxyChem. Was a plant electrician there. We produced calcium chloride in both solid and liquid forms. Calcium chloride destroys almost all metals, with the exception of monel, inconel and a very few others. Maintenance in that plant consisted back then (and almost certainly to this day) of replacing and rebuilding the plant as it was being destroyed by the calcium chloride products that it manufactured. This might be an exaggeration, but only a slight one. Any fastener - either nut and bolt or machine screw - that wasn't slathered with anti-seize would have to be chisled, cut or torched off after just a few months. To say it's corrosive to metals is an understatement.
rock salt is NaCl…………sodium chloride
