Houston was iced in this morn, most schools closed, accidents everywhere, overheads & bridges frozen. Noted on the local TV news trucks were spraying a chemical, calcium magnesium they said, on many roads.

This happens maybe once every 10 years here, so I'm not familiar with it. Bad for our rides? Do I need to go wash under the car with a pressure washer once it warms up?

...otherwise known to those of us in snowier climes as "road salt". It's not gonna kill your paint, but I'd get a carwash as soon as it's convenient--preferably one that sprays down your undercarriage.

Well after years of using deicing windshield washer fluid normally i have not noticed any paint peeling away at the front window from overspray etc. I've used a jug for those days when the wipers are in an inch of ice before, as well as a trunk that was frozen shut, no probs.

The deicer fluid uses methanol but it's a pretty small percentage. I have to believe that if that stuff was more than minutely harmful to car paint, that nobody would sell it.

My guess is that it will remove wax pretty easily but shouldn't be very harmful to the paint.
