Salt and chloride products should always be used in combination with shoveling, snow blowing or plowing. The products are not made to melt three or four inches of snow, rather they should be used to melt ice or stubborn, packed-down snow.
By using too much ice melt product at a time, consumers run the risk of clumps of salt forming and remaining on the concrete or asphalt after the snow or ice has melted. These remaining salt clumps can cause damage to walkways, driveways and landscaping.
The ice melt can cause concrete and some asphalts to crack. The product can also have harmful effects on pets that tends to go outside.
“Using too much ice melt product is economically wasteful. Environmentally, you’re contributing more chlorides that will eventually reach freshwater sheds," explained Phill Sexton, a primary sustainability adviser at WIT Advisers. "Salt that is over saturated can have a reverse effect, it can actually cause concrete to freeze."
