Ideal for clearing sidewalks, driveways and parking lots. Contains 90% calcium chloride, which penetrates ice up to 3 times faster than competing materials. The round shape of PELADOW helps it penetrate ice and break the bond with the pavement more quickly than flat or crystal-shaped ice melters, allowing easy removal of ice and snow. Calcium Chloride attracts moisture from the atmosphere. As the pellets turn into solutions, they give off heat to melt even more ice and snow. PELADOW is a purified inorganic salt produced by removing water from a naturally occurring brine solution. Unlike other processes used to produce calcium chloride, the brine process does not involve reactions with chemicals such as hydrochloric acid or ammonia. The National Organic Standards Board noted this distinction when it classified the brine process as “non-synthetic.” Solid calcium chloride is both hygroscopic and deliquescen, meaning the product can absorb moisture from the air, so store tightly closed.
