Salt brine is bad for cars, but best option for city streets, officials say
For six years, a salt and water mixture known as brine has helped keep major Madison roadways stay sleet-free.
But in that time span Mike Miyagawa, owner of M&M Autobody, has witnessed the powerful mixture take its toll on cars.
“Salt increases the corrosion by 900 percent, so it’s basically like an acid, and when it’s in the brine form it’s watery and it really soaks in,” he said.
Brine is bad for vehicles but is still the best option, according to the City of Madison Streets Division. The brine is 23 percent salt and 77 percent water. So it’s more cost effective and sticks to the roads more easily than only using dry salt.
“You actually wind up using less salt in the long run, because what happens is the salt stays in place longer,” said Bryan Johnson of the Madison Street Division. “That brine prevents the snow from binding with the pavement so you can plow it off and apply less salt later on.”
Miyagawa said the best way to keep your car safe is get your car washed twice a week, and while that may sound like overkill it will keep costly rust away.
