In Sweden they have a small % of gypsum in the road salt. Think it`s for the road salt flings to stay on the roads until the road salt starts to melt the ice/snow. They have in the later years started to both have the road salt flings. And have a wet road salt solution they apply on the same time.
When I did my military service on an airbase. We used Urea instead of road salt on the runway. Think it was that the airplanes magnesium wheels did not like road salt.
The Urea is also used as an addetive on diesel engines. It`s sprayed in the exhaust catalysator and makes much of the harmfull exhaust fumes into water. Semi-trucks and tractors and such machines uses it the most. I think that Volvo testing it in cars. It has it`s own tank and the product is called Ad-Blue. And is the most environment friendly diesel engine option today.
The TFR prewash foam takes care of the road salt for me. Then the oily road film that is left I use a tar degreaser to desolve it. If it`s too long since I washed the car. I need to do a touch wash after this. But if only a week or so the PW cleans it pretty good.
