We use the same thing as Washington DOT; calcium chloride, molasses and brine, basically a skanky beer.
No idea how to neutralize it, but this is what they use.

Whatever it is, it's corrosive as heck though. I think it's Calcium Chloride. Pierce County Road dept uses it too.... what I also saw was trucks running around with a full load of SALT in them two weeks ago.MTDIRK said:I don't think it is salt based, usually when I have seen salt corosion on metal it's white or a light color. This looks I drove through a group of hunters.

WSDOT only manages state highways and interstates. City/county road crews deal with the surface streets.
Annoying that the Pierce county road dept will drive around spewing that stuff on the road simply if freezing temps are forecast, even when no precipitation is coming... In other words the they lay it down on bare and dry roads, apparently thinking that "frost will form on the roads" so we better spread this stuff around first. :dhorse:
