Untreated rock salt is straight halite; treated rock salt is coated with a liquid brine that helps it work at lower temperatures and scatter less. For most Greater Boston storms, untreated does the job at a lower cost. Treated earns its keep in deep cold snaps and on commercial routes where every application counts.
Quick comparison
| Untreated | Treated | |
|---|---|---|
| Best range | Typical MA storms | Colder snaps, single-digit nights |
| Behavior | Standard melt | Faster activation, less bounce and scatter |
| Typical buyer | Homeowners, small lots | Plow contractors, commercial lots |
Both ship loose by the cubic yard. Compare them in the salt and ice melt collection, and keep either off lawns and plantings.
