An exothermic reaction takes place when the SuperThaw is in direct contact moisture, producing heat melting the snow and ice quicker.;Effective down to -25C (-13F), and stays active for 7 days;Environmentally friendly- leaves no mess and residue and is non toxic to plants, vegetation and aquatic life;Remove deep snow & sprinkle onto area to be cleared. Heat is generated when Super Thaw comes into contact with snow & ice;Can also be sprinkled onto ground to prevent overnight frost, ice and snow.
