Yet another cold weather yankee-ism, inspired by the fact
that we likes to put 1,000s of tons of salt on our roads.
This
And this or similar
Plus this as an inline soap dispenser

Makes for a right nifty under vehicle wash / salt removal apparatus.
Tin foil on the rear end may vent required.
Again - wrong on so many, many levels
Wrote a song about it, wanna hear it?
Nah nah nah - nah nah
Got chains on my shoe
Nah nah nah - nah nah
Spray soap up my truck
Nah nah nah - nah nah
Lookin' for the first woman
Nah nah nah - nah nah
Who wants me to,
kiss
