For icy steps and sidewalks in freezing temperatures, mix 1 teaspoon of Dawn dishwashing liquid, 1 tablespoon of rubbing alcohol and gallon hot/warm water and pour over walkways. They won't refreeze. No more salt eating at the concrete in your sidewalks.
You just spent a long winters night all snug as a bug in your RV glamper and step outside to ice covered tow vehicle windows. Simple solution of vinegar and water, just spray on and ice will melt away. Never scrape ice covered windows again!
