Shovel or plow the snow from your driveway prior to salting. This will uncover the layer of ice that is coating your driveway, which is what the salt needs to work on.
Sprinkle a thin layer of rock salt over all of the icy areas of your driveway. Spread the salt as evenly as possible over the ice, but avoid using an excessive amount; in the springtime, runoff from melting ice can damage your lawn and lawn ornaments if it is extremely salty.
Allow the salt to sit on the ice for at least two hours before checking on its progress. Use your shovel to break up any large chunks of ice, which will help them to melt faster. If any portions of the ice appear to not be melting as well as the rest, sprinkle more salt over them.
