Shovel as much snow and loose sleet off the driveway as possible. Do this while the sleet is still loose and has not frozen into sheets. If the sleet is already frozen to the driveway, shovel the snow away.
Sprinkle the ice layer with a calcium magnesium acetate--based deicer, or you can use rock salt. Rock salt can harm nearby plant life, so use it sparingly. Apply either deicer according to the package directions.
Let the deicer sit for 30 minutes. Use the sharp edge of the shovel or an icepick to loosen the ice around the top edge of the driveway.
Shovel the sleet off the driveway as you loosen it. Work from the top of the driveway to the bottom. Sprinkle sand over the bare driveway as you clear the ice away to provide traction and prevent further sleet from freezing over the surface.
