Has very limited ability to deice. Tends to lay on top of the ice.
Antifreeze evaporates quickly and the surface will re-freeze. Need for repeated applications.
Antifreeze tends to gel up and becomes difficult to spread and therefore loses effectiveness.
Rapidly penetrates ice. Once it reaches the surface it works from the bottom up.
Liquid Heat has residual properties that act as a barrier against re-freezing. No need for repeated applications.
Spreads easily and remains effective at temperatures as low as -60 degrees F.
