Sprinkling your sidewalk with salt is a must during winter storm season. (Hi, Jonas.) But if you’ve just run out of salt--and don’t want to make a hardware store run--here’s a nifty trick.
What you need: Leftover coffee grounds from a few morning brews and a freshly-shoveled sidewalk.
What you do: Sprinkle the grounds along the walkway (as you would with salt).
Why it works: Like sand and salt, the grounds give you extra footing for safer stepping. Plus, the acid helps ice melt faster.
