Potassium formate efficiency compared

Potassium formate, a formic acid salt, is more efficient than other de-icing agents such as:

• Potassium acetate
• Urea
• Glycerol

Compared to potassium formate, taken at a relative efficiency of 100%, potassium acetate has an efficiency of only 80 to 85%, depending on the prevailing temperature.

This compares to an efficiency of about 70% for urea and 45% for glycerol.
