You warm weather guys can have a laugh
 

Here's a nice pic of formerly detailed cars and a garage floor that you could have eaten off. All now covered with a slurry of magnesium chloride. So there goes Saturday afternoon . . . .

Rick, I think Magnesium Chloride is better than salt as far as eating concrete goes, but it's always a mess. I forgot what Seattle uses here now, used to be brine from dairy farm (by product of cheese making). The good thing for us only snow once in a while though.

Melting Snow & Ice with Salt

Wish I had a garage like yours:wow:

Most areas use both magnesium chloride and salt. What is used is dependent on the temp.
