The specific ingredients, particle size and colouring will all contribute to the performance of an ice melter.
The most effective ice melters use consistent, medium-sized granules which can bore through the surface and maximize brine formation.
This breaks the ice-to-surface bond, allowing for easy removal of the remaining ice.
Products that are mined, such as rock salt, may contain a wide range of particle sizes with unpredictable and uneven melting characteristics. Alaskan formulations include calcium chloride flakes, which allow for a greater surface area when contacting ice and snow.
The most important ice melter characteristics are: effective melting temperature, melting speed and product safety.
