Anyone wants to keep their sidewalks, and driveway free of ice and snow, use the following recipe.
Mix 1 teaspoon of Dawn dishwashing liquid, 1( or 2) tablespoon of rubbing alcohol with 1/2 gallon of hot water. Pour over or spray walkways and driveway. They will not refreeze. No more salt eating at the concrete in your sidewalks. This will save you a lot of money in buying de-icer. You will not be tracking in salt in the house from this.
This was also in the Nashville Pharmacy Magazine this week.
