How To Melt Ice Without Damaging Concrete
Shovel or broom.
Hi Cherlyn: Apparently, a solution of one teaspoon of Dawn dish soap, one tablespoon of rubbing alcohol, and 1/2 gallon of hot or warm water is all you need to combat icy stairs and walkways this winter. If you pour the solution over these areas, they won’t refreeze. The benefit of using this method as opposed to road salt is that the salt eats away at the concrete in your sidewalks and walkways over time. Good luck
Hi Cherlyn, see if any of these posts can help you:
