However, some snow and ice melters take longer to work than others. Generally speaking, the speed at which a de-icer begins to work is determined by its' ability to form a brine and is therefore influenced by how rapidly it can absorb moisture.
Temperature plays an important role when comparing melting speeds of various components.
Nearly all de-icers will attract moisture when applied above 25 degrees Fahrenheit. By contrast, most salt and potassium-based products show little to no ice penetration once temperatures slip down to 15 degrees Fahrenheit or lower.
