Just made it through my first CO winter. Lots of Mag Chloride on the roads. I think half of it is caked on my rear door (2010 Xterra in Super Black)
Any secrets to ridding my beautiful paint of this crap?! Thanks!
I am very good about my paint. Self hand wash and wax only.

You can try to get it off with hot water.... and you better, or it will eat away everything!
