Will kosher salt melt ice on sidewalks?

Yes, kosher salt can melt ice on sidewalks, but it's not as effective as rock salt (sodium chloride). Here's why:

* Smaller crystals: Kosher salt has larger, irregular crystals compared to rock salt's smaller, more uniform crystals. This means it takes longer for kosher salt to dissolve and release the chloride ions that melt ice.

* Higher cost: Kosher salt is typically more expensive than rock salt.

* Other uses: It's primarily intended for culinary purposes.

Alternatives for ice melting:

* Rock salt (sodium chloride): The most common and effective option.

* Calcium chloride: More effective than rock salt at lower temperatures, but can be corrosive.

* Magnesium chloride: Less corrosive than calcium chloride and effective at lower temperatures.

* Potassium chloride: Environmentally friendly but less effective than other options.

Tips for using salt on sidewalks:

* Apply in a thin layer. Too much salt can be harmful to plants and pets.

* Spread evenly. Ensure the salt is distributed throughout the icy area.

* Sweep up excess salt after melting. This helps prevent damage to plants and concrete.

While kosher salt can melt ice, it's generally not the most efficient or cost-effective option. Rock salt remains the preferred choice for de-icing sidewalks.
