Ways to Prevent Rust From Road Salt



One of the best things you can do for your car or truck this winter is to protect it from rusting.


Despite how damaging it is to cars (not to mention the environment), the United States uses over 20 million tons of road salt every year. With tens of millions of tons of that good old sodium chloride hitting the roads annually, it’s essential to know what kind of damage salt does to cars.

Rock Salt vs. Road Brine

Salt brine is a solution of salt and water that has a freezing point lower than water alone. In turn, salt brine can reduce snow and ice adhering to road surfaces. Once the brine is applied, it can be seen as white lines on the roadway.

Brine has another tremendous benefit: It’s cheap.

The salt used to mix brine costs $89 per ton, which produces about 2,000 gallons of the liquid formula to treat area roadways.

What is road brine made of?

Brines can be made with sodium chloride, calcium chloride, or magnesium chloride. The freezing point of brine is a function of the salt being used in the brine, such as if sodium chloride, calcium chloride, or magnesium chloride was used, and the percentage by weight of that salt in the brine.

Rock salt is simply crystals of sodium chloride, or table salt, just not as refined. Until rock salt has been formulated into the brine, it will do nothing to stop snow from freezing to the roadway. Agencies that use rock salt in their winter maintenance activities are doing so to create brine on the road surface by having rock salt mix with snow, ice or freezing rain.

An effective anti-icing program with liquid brine reduces de-icing efforts, materials, and equipment. Anti-icing with liquid brine returns roads to passable conditions quicker, resulting in fewer delays or incidents.


Road brine Ingredients

Everyone who lives near the coast knows just how dangerous salt is to metal objects — but what happens that makes it such a problem? Ordinarily, rust — known as ferric oxide — forms when the unprotected metal comes into contact with water and oxygen, causing a chemical reaction. When salt is added to the mix, it lowers the electrical resistance of water, making it easier for the chemical reaction to occur and thereby intensifying the rusting process. This is what happens when road salt/brine and snow come into contact with the metal in our cars or any other transport vehicles — including trailers, boats being transported, and trucks.How do I Protect My Truck from Road Brine

Can salt brine be removed in a carwash?

Salt brine removal during the winter months is one of the most common reasons for people to bring their vehicles to the car wash. But is that car wash removing the toxic mix or driving it deeper into your body cavities?

Because most liquid deicing solutions now contain sticky additives designed to adhere to the roads, don’t discriminate when your vehicle drives over them. Also, make it much more difficult to remove in a conventional carwash.

Take into consideration most carwash facilities recycle a percentage of water. Are they removing this liquid salt or driving it deeper into the body cavities?

The only way to remove a liquid deicing solution with sticky additives is to use a salt brine remover that’s specifically engineered for the application.

One other thing to consider, car manufacturers don’t design their vehicles to have high-pressure water shot into the undercarriage and may not allow for proper drainage.

Preventing Road Brine Rust


Whether you’ve noticed a rusty spot on your vehicle or want to prevent rust from forming, there are budget-friendly and highly effective. Products that are easy to use, effective and affordable, and your vehicle will have the high-quality control and protection it needs to stay rust-free this winter.


NH Oil Undercoating is a unique blend of highly refined Mineral Oil,  & Green Corrosion Inhibitors that guard against rust and corrosion on all metals. It eliminates moisture and oxygen while providing a barrier against salt, dirt and other pollutants from the metal providing long-lasting protection for your vehicle.  Pleasant smell.Fluid flim Woolwax

Penetrate & Lubricate

After NH Oil Undercoating® is applied, you can expect it to lift and remove dirt, moisture, other contaminants, and even some surface rust. It is designed to penetrate to the good metal and form its protection there. It will continue to penetrate to the good metal, pushing out existing moisture and oxygen, thus eliminating oxidation-corrosion.

Stop Electrolysis

NH Oil Undercoating® stops electrolysis by disallowing the external circuit to be completed. NH Oil Undercoating is designed as a non-conductive material that also has a voltage drop of only 1/100th of a volt. After securing the connections, it can be used on electrical connections to prevent the “greening” of wires.

Active Molecular Protective Film

Once NH Oil Undercoating® has reached the good metal, it sets up a bond. This bond is at a molecular level and the film that is created is ultra-thin providing long-term protection. The inhibitors, meshed together in a chain link, are then used by the environment – contaminants, salts, etc… – before the metal is rusted.

Creeps and Self Healing

NH Oil Undercoating® is designed to creep deep into cracks, crevices, spot welds, seams, folds and provide protection there as these areas up prone to hold moisture and are unprotected. So even if the initial application cannot reach one of these areas, this ceeping process makes sure the maximum protection is provided!How do I Protect My Truck from Road Brine

Can we improve the appearance if there’s existing rust?

Yes. NH oil undercoating® Back N Black not only protects but it improves the appearance of any metal surface!
