Wash frame or wait?

After getting hit with a blizzard,my entire truck is covered in salt, sand, and that's nasty road spray crap. The salt is essentially all dry on the frame so I'm guessing it is inactive. I'm thinking of holding off because the next couple days are going to be warm and all the rest of the snow and salt is going to flood the streets.

My question for you guys is; should I wait to clean my frame off (it is fluid filmed) or should I do it as soon as possible? What's the best way of soaking everything without taking a lot of the fluid film along with it(any recommended soaps, chemicals)?

 

I'm gonna wait till this weeks rain to wash the salt of the roads, then maybe this weekend I will wash it, I'm in va

 

Did you cross post on purpose?

 

I tried posting this to the 2nd gen forum and an error occurred, then tried in the detailing forum, but both went through.

 

I'd wait till the roads were washed clean of it.
