Sprinkle a salt, such as calcium chloride, potassium chloride or ammonium sulfate over the area covered with snow. Use about a cup of salt for every three feet of snow area.
Spread sand over the snowy area. Sand absorbs sunlight and will heat up the area where the snow is and dissolve it. Use the same amount of sand as you would salt.
Sprinkle alfalfa meal (a fertilizer) over the snowy area. Use the same amount of alfalfa meal as you would salt and sand.
Sprinkle white vinegar over the snowy area. Use about a cup of vinegar for every five square feet of snow.
Throw hot water over the snow area. The heat of the water will dissolve the snow. You'll need a lot of water to do this however; use about one cup of hot water for every one square foot of snow area.
