Saltnets' mats work just like rock salt, because that’s what is inside. But these de-icing mats are faster, neater, and more efficient. The melting agent stays contained in the durable nylon case, and only releases when there is moisture from snow and ice. Once the area is clear the nylon quickly dries, which stops the process.
Use one of these mats at the front door, or on the landing, or anywhere else where ice builds up. Or place one on top of an icy area to work its melting magic after a few passes with the shovel. While the mat will eventually melt through deep, heavy snow, dig out as much as possible to help it work more quickly.
Reap the benefits of ice melt in a more concentrated, controlled way, and help make those slick areas safer.
