Road Salt Brine

Most of us know what ROCK SALT is, but what about Salt brine? Well if you don't know what it is then you probably don't know what it's doing to your car. Traditionally most states use rock salt to de-ice the roads, But some state are using a salt brine solution.

Salt brine is water saturated with sodium chloride simply put "rock salt dissolved in water". It has a freezing point lower than pure water which aids in reducing the adhesion of snow and ice to road surfaces. In addition to brine made with sodium chloride, some agencies also use brines made with calcium chloride or magnesium chloride. either way, these brines are a solutions of salt and water. The freezing point of brine is a function of the salt being used in the brine (sodium chloride, calcium chloride, or magnesium chloride) and the ratio of that salt in the solution. They could use Calcium Chloride instead of Sodium Chloride. It is both less corrosive and a smaller amount is needed, the problem is that it is a bit more expensive and requires sealed storage because it absorbs water from the atmosphere.


Road-de-icers-cause-3-billion-annually-vehicle-rust-damage (see AAA Link) drivers spent about $15 billion over the past five years to repair rust damage to brake lines, fuel tanks, exhaust systems and body parts which has been accelerated by a chemical used to keep roads from freezing in the winter. The ice fighting characteristics that make pre-treatments such as brine attractive to agencies are more damaging to vehicles than rock salt because the chemicals stay in liquid form longer and are more likely to coat components and seep into areas where corrosion can accelerate, the report said. Drivers should avoid driving on highways immediately after they have been treated with brine.


Rust Damage

AAA recommends: Drivers should get their vehicle washed after a storm, including an undercarriage wash, which is available at most car washes.


Undercarriage Wash

Although we can't stop the rust completely we can take some steps to reduce the possibility of damage with some preventive measures.


Limit your driving during the de-icing application process. Never drive behind the trucks applying the brine solution.


Go to the car wash as much as possible during the winter, paying particular attention to the undercarriage. This will loosen, dissolve and neutralize road salts. Many drive-through car washes offer an undercarriage rinse as an option.

1. Use an under carriage sprayer to clean under you vehicle.

2. Take your car to a "ziebart" type place to spray the undercarriage of your car. Which should put a barrier between the salt and the components of your car.

3. Move to a state that does not have snow. (which would be my choice). Sorry I had to add this one.


No Snow!

Needless to say removing the salt brine solution from your car as soon and as much a possible is the only way you are going help save your car.


Well until next time.
