Over here deicing is frequently done with brine because it sticks better to the road and doesn't get blown away, so I'm very skeptical about the salt being useless when it's wet.
- kapitalx 6y agoTo add to this, there was a piece on NPR a few days ago where they talked about brine as a more environmentally friendly option to rock salt. De-icing salt gets into lakes and streams, and with brine you need much less salt to achieve the same results apparently.
- tnorthcutt 6y agoThe point was that rock/crystal salt is useless if it gets wet, because then it can't be reasonably used/moved/broadcast. If it turns into giant bricks of salt, it's impossible to work with.
