How corrosive is it? The grey or white powder it turns into seems not good for metal. I had a CDOT friend (enginneer:rolleyes:) tell me the stuff is OK, yea, right.

Man, Highlands Ranch (douglas County) went postal on putting it down on the roads early Saturday morning, for what seems is no reason. I mean, they really laid it down. It seemed slippier (sp) than greased moose poop. When I crossed north of County Line road on Broadway, the streets were perfectly dry, Arapahoe County and City of Littleton did not lay any de-icer down. The stuff was still wet last night going home!

I got that stuff washed off on my way into work today, major frozen water on the vehicle.

three seasons on a stainless MBRP exhaust on my Duramax, and it has surface rust all over it.

Its totally fine stuff...

The cheaper ice cutter is corn oil based. If the temperature is less than 20 they are supposed to switch to the mag chloride. Most cities use a blend to keep costs down. The offical word is that mag chloride is not corrosive unless exposed to oxygen.

What color was it? Granular or just plain liquid.

CDOT uses Ice Slicer RS, which is 95% rock salt with a few trace minerals. As for liquids they use Caliber. Most other munis use the same products and they get them from: http://www.envirotechservices.com/

I use Ice Slicer. Is it corrosive.... not as bad as straight salt, but I wash my truck and spreader religiously. I also use some chemicals on my truck to reduce the chances. It plays havoc with my tail light and trailer wiring...

The mist caused by mag-chloride and similar agents has increased the number of transformer fires as well as the number of dead trees along the side of roadways.

Duh, so we should cover the roads after they put it on :D

Ask Toyota/Lexus if they will warranty the chrome parts? Ben knows the answer to that one...

Not warranty. Even when I was at Lexus it was no, and they'll buy almost anything under warranty.

Among the various reasons that munis like mag chloride over regular NaCl is that it is 3 ions per mole, which makes for more freezing point depression per unit purchased.

It's as least as corrosive to our Land Cruisers as regular NaCl, and seems more so on my empirical observation.

If everyone drove a Toyota 4x4 they wouldn't need to use it at all.
