Simply scatter your leftover coffee grounds liberally on icy patches along your driveway or walkway. Their coarse texture mimics sand and provides some much-needed traction.
Further improve your footing by applying coffee grounds to ice-covered areas on sunny days. They will absorb the sun's rays, making them warmer than the ice around them.
While coffee grounds alone can't melt ice, when coupled with direct sunlight and mild temperatures, they can radiate heat and slowly thaw nearby items.
