Color Bleaching-

Rock salt and certain de-icers will cause discoloration on surfaces. As a result, the surfaces may look like they were bleached. This is a notorious occurrence when salt is left to sit on natural stone products such as bluestone. This bleaching effect can result in small discolored spots or even discolor an entire stone.

What De-Icers are Safe?

Calcium Chloride-

One of the benefits of calcium chloride is it has a freezing temperature of -25°, which makes it an excellent choice for those looking to melt ice quickly. It works exceptionally well for people who live in freezing climates during the winter.

Magnesium Chloride

Magnesium chlorides freezing temperature is of -13°, which makes it one of the better alternatives to handle ice in the coldest temperatures.
