Salt will “work,” i.e. it will melt ice, all the way down to its eutectic temperature of -6 0F. However, the “practical working temperature” of salt is generally considered to be higher than this.
At what temperature is salt not effective?
At a temperature of 30 degrees (F), one pound of salt (sodium chloride) will melt 46 pounds of ice. But, as the temperature drops, salt's effectiveness slows to the point that when you get down near 10 degrees (F) and below, salt is barely working.
How long does rock salt take to melt?
It starts to melt as quickly as straight calcium, but lasts as long as other sodium/potash blends. Below is a graph of melt volumes produced in 20 minutes at -10°C (14°F). An ice melter's granule size and surface area both affect the melting process.
