Clear snowy and icy surfaces with ease and make them safe for others with Road Runner Ice Melt Blend. It's made with a combination of magnesium chloride and calcium chloride that begins melting ice down rapidly, turning it into slush that can easily be shoveled away. The formula is effective in temperatures as cold as minus 15?F. It's also safe to use around flowers and other vegetation when used as directed. Use it on sidewalks and steps around the house, at schools, businesses and elsewhere.
