McHenry drivers should protect their cars from oxidation of road salt

That white powder on this SUV is a mix of

road salt and dirt. Bringing your car to a

McHenry carwash will do more than make

your vehicle look better; it will also slow the

oxidation process that harms your vehicle's

finish.

If you think that winters in McHenry often present us with environments that can send cars slipping and sliding, you’re right. But it’s not as bad as it might be since we use road salt to melt the snow and ice on the road. Clearly, this time of year, road salt is essential to safe driving.

Of course, there is a down-side to the road salt if you consider what it does to your car. McHenry drivers would do well to consider the effects of road salt.

Road salt will cause corrosion to the metal parts of your car that are exposed to the element, especially when mixed with water. And the water comes from the sky in the form of rain, sleet and snow. It also finds its way into the undercarriage of your car when your tires, and the tires of other drivers, fling it up from the road and across your vehicle in a fine chemical mist. The process that takes place when this salt-enriched moisture comes into contact with your vehicle is called “Oxidation.”

Oxidation is the same process by which your car’s paint fades if you leave it under the UV rays of the sun for too long. The process of oxidation causes a chemically heated reaction. It dries out the paint causing it to lose its sheen while reducing the effectiveness of the paint as a shell to protect the metal underneath.

That moisture loaded with road salt also carries other contaminants, such as particles of dirt, rust, carbon powder and other chemicals picked up from the roadway. With the oxidation, this will leave a chalky film on the surface of your car. In the meantime, the paint is beginning to dissolve.

If you poured some water in a coffee can full of metal nuts and bolts, you would later find the parts coated with rust. This is the process of oxidation on metal. This is what oxidation is doing to metal parts under your car. This is also why the body metal of cars eventually rusts through.

You’ll notice, on cars with rust spots, the rust appears where the mixture of water, salt and other particles collects inside the body of the car. Overtime, if you don’t take steps to slow or stop the process, oxidation will cause metal parts to deteriorate until they no longer function as intended.

Oxidation does more than dull and diminish the finish of your car, or eat at metal surfaces; oxidation deteriorates the value of your investment in your car.

So, what can you do about it?

Take your car through the carwash. Whenever you see that chalky finish on your paint, take that as a sign and hit the carwash. You’ll have the satisfaction of driving a shiny car for a while and you’ll preserve that finish, and the value of your car, in the process.

Is your antifreeze safe from freezing this Richmond winter

You still have time to have it checked Well, there’s no denying it – winter tends to get chilly here in Richmond. We have to deal with snow and ice on the roads, scraping the same off our windows and windshield, and staying warm while we drive. Of course, you had your antifreeze checked before winter rolled into town. What?! You didn’t have your antifreeze checked before winter clamped down on Richmond? So, how’s your antifreeze doing? If you haven’t had it checked, there’s really no way of knowing, is there? This car has overheated in the middle of a Richmond winter. But, on the other end of the spectrum, the antifreeze can also freeze if it's not up to its job. Hopefully, you haven’t had a serious problem with your antifreeze already. If you did, you’d probably know. When antifreeze fails, it’s a potentially catastrophic condition for your vehicle’s engine. You could have hoses that have burst because of freezing antifreeze. Worse than that, your engine block may have crac...

Blocks of ice falling from cars in McHenry could cause accidents or damage

We’ve all seen those blocks of snow falling from behind the rear tires of a car when the snow rolls into McHenry . Fortunately, they’re just packed snow that will disintegrate under your vehicle’s tires as you simply drive right through them, right? Don’t count on it. Those blocks of snow are often packed so tight, condensed by the thaw-and-freeze cycle, that they’re anything but oversized snowballs . They’re often more like boulders. Hit one of those blocks and the collision between the block and one of your tires could send you careening off the road or into oncoming traffic. In some cases, they’re so solid you could pound them with a sledgehammer with little effect. They truly can represent a serious road hazard. The problem is that it’s difficult to tell how solidly they’re packed when you see them on the road, left their unwittingly by another driver. Either way, your best bet is to try to avoid them. But you want to be careful dodging blocks of ice in the road, too. You need...

October 20 Hootenanny will benefit veterans with PTSD

Been to a Hootenanny lately? When you read that question did you ask, “What?” Well, if you have gone to a Hootenanny in a while, or if you don’t know what a hootenanny is, we have an event for Oct. 20 that will clear up either question. From 6 p.m. to Midnight, Saturday, Oct. 20, MC3, the McHenry Area Chamber of Commerce business networking group, is helping to host an inaugural Veterans R&R Wild Horse Hootenanny at Beyond Stable Farm (11129 Rte. 176, Woodstock). The event will benefit Veterans R&R Operation Wild Horse. Operation Wild Horse serves veterans with PTSD (Post-Traumatic Stress Disorder). Working with the horses has proven to have an incredibly calming effect on the veterans. And, it’s good for the horses, too, rescued wild mustangs. This means that the hootenanny is for a very good cause. But, it’s also a lot of fun. So, what is a hootenanny? According to a Google search, a hootenanny is “an informal gathering with folk music and sometimes dancing.” The V...
