What is rust?
Rust, Corrosion, Metal Cancer—all more properly called iron oxide. It’s the stable form of steel. Iron ore, the raw mineral we mine to make steel, is actually iron oxide. Rust! That’s right, steel is made from rust. It spends the rest of its life trying to return to its natural state.
In order to have rusting take place, you need three things: Steel, Oxygen, and Heat. It’s just like the three items needed for a fire: Fuel (the steel), Heat (any temperature above freezing), and Oxygen (to support the burning or rusting).
In fact, rust can be thought of as a slow burn, like charcoal, where rust is the ash.
Rust is actually an electron exchange. Steel gives up an electron and becomes rust. It’s a process related to electricity. In fact, anywhere two different metals touch, there is an electrical current generated.
Rust Check has a high dielectric value (electrical resistance) of over 20,000 volts. It resists the electron exchange which greatly retards rust. In our climate, it slows corrosion by 80-90%. It takes 8 or 9 years to rust as much as a single year without Rust Check.
North American Corrosion Belt
We live in one of the most corrosive areas of the world. Only the east coast of Nova Scotia and the Avalon Peninsula of Newfoundland are “blessed” with a more corrosive climate than ourselves.
The entire North East is in a severe or very severe corrosion area. As is the southern coast from Mexico to Cape Canaveral, FL.
Up north, we receive two acute catalysts for rapid corrosion.
Salt. Salt is mostly spread on the roads to help prevent accidents in winter. This makes our roadways, which receive over a ton of salt per mile over a typical winter, the corrosive equivalent of the “Marine Splash Zone” (see the photo above). This zone is the most corrosive environment on earth. Interestingly, it’s not salt that hurts your vehicle, but rather salt water. When dry, salt has almost zero catalytic effect. When salt is dissolved in water, it easily doubles the rusting rate. With every 5 degree rise in temperature over the freezing point, this rate re-doubles again. This is why untreated vehicles rust faster in the spring!
North American Acid Rain Deposits
We are in the downwind area of the greatest industrial area in the world. Unfortunately that gives us a concentrated dose of acid rain, and acid snow.
The corrosion map when compared to the acid rain deposit map to the left, shows this very eloquently.
Areas that heavily salt their highways, such as northern Ontario, Minnesota, and northern Michigan, are out of the acid rain fall-out area and so report very little rust!
The footprint of the heavy acid rain deposits is almost identical to the shape of the extreme corrosive climatic areas of North America.
If you operate a vehicle in these areas, you need an annual Rust Check!
