The salt the County puts on our roads for six to seven months is “crystal” rock salt (90 degree cleavage) from the mines under Detroit. The table salt we use is “crystal” rock salt (90 degree cleavage), much of which comes from the mines under Detroit.
All of this salt “sucks up” (absorbs) moisture. Our roads have already been dumped on with salt and remain wet for days after any precipitation.
Guess what ? The @#$%&**! salt that is dumped by the buttload all over our roads for months every year seriously damages our cars !.
roben 123, what mark did you get in highschool chemistry? Salt is salt and is Sodium Chloride (NaCl), in both table salt and road salt. However, road “salt” also has Calcium Chloride added, and it is deliquescent; it loves mositure and depresses the freezing point even more.
Table salt usually has iodine added (to reduce goitre)and is treated not to cake or stick, but it’s still the same salt.
Some years ago a customer brought in his 356C for a look over. The car was a CA. car but was totaly rusted out underneath simply because of proximity to ocean.
We’ve had several psts on this and the driests parts of the US in the West (not on the coast) are 26 TIMES less corrosive that the areas around the Great Lakes, and the North East. Carl Ziebart, the inventor of Ziebart rustproofing, was an auto mechanic in Detroit an did not like what he saw, long before the federal government legislated “rust perforation” guarantees in 1976 or so.
