I've have to sand my uphill driveway because it freezes in the middle of melting and was black ice you can't even walk on.I don't know what part of the east coast you live in but there can't be any hills, or sloped concrete driveways that has melted and then frozen back up .
I keep several buckets of dry sand in the garage just for the frozen melt. Don't need salt, just sand.
Plus we can't have salt on the dog's precious feet.
I've had pretty good luck with just turfs too.
