I have wondered WHY no major car-care company has developed and sells a salt-neutralizing soap, but then the logic of doing so is self-apparent (AKA obvious to Captain Obvious!). What vehicle owner washes their vehicles at home outside in the winter where de-icing salts and chemicals are used on roads? It`s too cold to do so, so hence, there is no market for doing so, or at least it`s a limited market for OCD Autopians, like myself. who are just crazy enough to want to wash their salt-encrusted vehicle in the rare above-freezing days in the winter. (By the way, this has been THE most unusual winter weather in Wisconsin I have ever seen in my lifetime. We go from above freezing high temps to sub-zero temps on what seems to be a 10-day cycle, with at least two of those days being above freezing. Good for washing vehicles outside on the more-than-frequent "warm" days.)
I also think that salt-in-the-air is a problem for vehicles kept and driven near the salt water of the Atlantic and Pacific Oceans and Gulf of Mexico coasts, but again, it`s a limited market. Maybe regular car soaps used for owner-done vehicle washes will take care of that; I don`t know because I do not live in that salt-water environment.
Anyway, this is a great thread discussion. Wonder if tunnel/automated car-washes in areas that use de-icing salts have "special" wash soaps specifically for neutralizing that road salt designed for such car washes. I do know that cleaning of beet-juice de-icing binder used by many municipalities plowing and de-icing road departments on roads where snow falls is a REAL problem to remove in such touchless washes. This Road Traffic Film (RTF) is near impossible to remove chemically with specialized cleaners or at least those chemicals needed for such cleaning are not "legal" (AKA environmentally safe per federal EPA legislation) for use in the Untied States.
