Make a Salt Alternative
The spreading of salt in the wintertime is so common where I am from that I was actually quite surprised to learn what kind of damage the habit can inflict on local roads and sidewalks. Apparently the mineral slowly eats away at any hardened concrete it comes into contact with.
1 tsp of generic dish liquid
1 TB of rubbing alcohol
1/2 gallon warm water
Combine the above ingredients together in bucket and pour the mixture over sidewalks and pathways to quickly melt ice without damaging walkways
Use the No-shovel Solution
Did you ever protect your car windshield from excessive ice and snow by placing a piece of cardboard on top of it to find a clean, scrape-free windshield when uncovered the next morning? This hack works similarly. When a winter storm is anticipated, place a plastic tarp over exposed sidewalks and walkways, with each corner held down by bricks or pieces of firewood. As odd as it sounds, once the snow flurries end, all one must do is pull on the corners of the tarp, uncovering a unsoiled, unfrozen path.
