Cover the icy driveway with alfalfa meal early in the day. Cut open a bag and use a cup as a scooper to spread it generously over the surface. Alfalfa meal is a natural fertilizer available at nurseries and gardening shops. It's loose and gritty so it offers traction while melting ice, and contains smaller amounts of nitrogen than other fertilizers so it’s less corrosive.
Wait for the high noon sun to melt the ice as much as possible.
Scoop up loose patches of ice with a rubber-tipped snow shovel and dump them on a snow bank near the street end of the driveway.
Go over any remaining patches of ice with a metal rake or hit it with the tip of a shovel to break it up.
Scoop up remaining chunks of ice with a shovel; use a heavy-duty broom to push any melted ice off to the side of the driveway before it refreezes.
Shake another layer of alfalfa meal over the driveway to help melt any new ice that forms overnight.
