Turn a snow or leaf blower on and clear away any loose snow from the pavement. This prevents the snow from freezing to the ice, making it thicker and more difficult to melt.
Spread coarse sand over the driveway. In addition to melting ice, sand lends traction to slippery surfaces, making them safer to walk and drive on.
Scatter alfalfa meal over the entire driveway by shaking it off of a shovel. This is a natural fertilizer that’s also dry and gritty so it adds traction as well. Used in small amounts at a time, the low levels of nitrogen are less threatening to plants and the water system than some other natural options.
Pour urea, a natural fertilizer, over patches of ice and let it sit for about an hour to loosen the ice. Note that urea is safe for animals and less corrosive than chemical deicers. Avoid using urea on thick patches of ice because a large amount can burn plants.
Shake a cup full of salt over the pavement. While rock salt is widely available in winter, liquid solutions are also effective. Note that salt is harmful to metal, pavement and plants. Consider using it as a last resort, when other materials aren’t available, to prevent damage to your car. In some areas, salt runoff can also affect drinking water.
