With the freezing here in Dallas last week, the road department used a sh!t-ton of Magnesium Chloride de-icer and I had to drive through it with my truck, about 20-miles over 2-days. On the 4th day after exposure I was able to get to the car wash and spent a good 4-hours pressure-washing everywhere I could reach but the damage was already done, the chrome on my Centerline rims is ruined, I guess I will have to re-chrome them in the future.
So I am still worried about Magnesium Chloride, there is very little information on this stuff and what I understand is that it is even more damaginng to vehicles than [older] road salt. Road Salt will dissolve in water, so high pressure washing will eventually produce a clean undercarriage, but from what I understand Magnesium Chloride is not water soluble, you need some certain chemical spray treatment or spray wash to get the vehicle actually chemically clean again, and until you do it is coated in an invisible coating of the deicer which continues corroding. Many truckers complain that their rigs are literally falling apart from Magnesium Chloride, I don't want the same happening to my truck. Do you guys have any info on what we can use to get this crap off our undercarriages?
How ironic is that, to have an all-wheel drive truck you can't drive in winter weather because of the road department chemicals that dissolve your truck to nothing...
