At A Glance
Tools Of The Trade
Grit/Gravel: Adds traction to ice or packed snow but does nothing to melt it. Washington County uses only limestone gravel — no salt.
Salt/Brine: Salt lowers ice’s melting point to about 15 degrees and is most effective if put down before freezing begins and isn’t washed away by rain or snowmelt.
Beet Juice: Used by several cities and the state, beet juice can amplify salt’s effects and push ice’s melting point to between zero and minus 25 degrees.
