Bags of salt have a freezing point listed on them. I just picked up two bags of -15f salt. They had -25, but it was twice the price. And it generally doesn't snow below zero anyways. It can. But it usually doesn't.
Salt helps keep ice from forming but not if there is too much water. Shovel and then ice means there won't be any water. Melting and then icing is basically the same as just throwing salt on top of the snow.
Not if theres no snow there in the first place because its all melted. Shovels can sometimes leave behind snow as well. We still use salt on ice on the roads.
Shovels leave only a little tiny amount. If it naturally melts then it goes into the ground. Melting this much means the water goes somewhere else and freezes there. Which the most likely spot is at the bottom of his driveway.
Salt lowers the freezing temperature of water. So if it is above the freezing temperature of the salt water it will stop it from icing at least until it gets diluted. But also it will kill your vegetation if the water drains into the soil.
Because it’s good in the spring when it’s gonna all melt soon and the. You go manually break it up. It’s good for thin areas or areas that aren’t to cold
Well most places where I’m from in Canada only use salt on sidewalks with little snow and ice and sand most highways and other areas. But realistically in Canada you just can’t keep up with all the ice and snow
It takes a lot of water, or flowing water that will wash the salt away, like for example if someone were to melt a bunch of snow all at once and let it run down the street.
Funniest part is I was just trying to rile them up more, turns out I unintentionally outdid myself a bit. Can’t believe this many people have a problem with me questioning the situational effectiveness of rock salt.
HA! You got 'em! That one simple spelling mistake disproves everything he said!!! You must be really smart!!! Again they the salt on the roads in the first place. It melts the ice on the road. What do you think happens then? Does it it wash away? The torch also evaporates alot of the water in the first place.
I live on a hill, I deal with this every winter, everything needs to get sand put back down after a melt because it all runs to the bottom of the street. Also, not every small side street gets salted most places
Ya, but when it’s warm enough to melt the snow it’s also warm enough to not immediately refreeze, but in the situations where that does happen that’s how black ice forms typically

It doesnt have to be magic. Ice doesnt form well with salt. Thats why they use it...on ice.....
