Why Does My Car Get So Dusty? [Inside And Out]

No matter where you go, dust is inevitable. It's on your furniture, your tools, and in the air. Though, one area that it seems to like the most is the car. Why does it get excessively dusty on the inside and outside? If that's your concern, let's go over the details. 

Dust doesn't appear out of thin air. It's a collection of particles like loose clothing fibers, hair, and dirt. Static electricity makes them stick to car surfaces. Generally, car material carries a negative charge that attracts positively charged dust particles.

You can reduce the dust on the outside of your car by keeping it covered when not in use. You can cut back on interior dust by changing the cabin filter and keeping the windows closed as much as possible.

At this point, you might be wondering how you can combat static electricity. After all, it's the source of your dust problems. Is it even possible? These are some of the concerns we'll discuss in detail. To learn more, keep reading.

How Dust Settles On Car Surfaces

Dust is a collection of contaminants that become airborne. If you look closely, it can be dirt, loose fibers, and other types of debris. Of course, we share a community with people and other living things. 

So, it's easy to see why the outside of a car can get so dusty. We can rarely control our outside environment. Some people live in naturally dusty areas. 

Others live in areas with tons of wildlife. So, the dust you see on the car can be a simple build-up of animal fur and loose clothing fibers from people walking around. 

Static Electricity

You might already know the information above. Therefore, we should get into the specifics. How exactly does dust settle on the outside car surface? Wouldn't it slide off if it's loose fibers and all that?

The simple answer is static electricity. Though, it raises the question, how does a car build that up? Any action that involves friction causes static electricity.

That involves most actions you do. You're likely carrying a static charge without ever knowing. In any case, a car's exterior goes through many motions that can cause it. 

A mass moving through air causes static electricity. The mass, in our case, is the car. Other activities that cause friction are buffing and polishing. 

It's why the car appears to be a dust magnet after waxing. Though, it won't attract as much dust once the static energy goes away. 

How Does Dust Appear In Car Interiors?

The inside of the car is where it can get confusing. Since you're in an enclosed area, how can dust settle inside? Assuming you don't leave your windows open, it's still a matter of static electricity. 

We wear things that produce dust. Additionally, every time you get into the car, you're dragging dust inside. Though, one aspect that comes to mind is frequency. 

No matter how much dusting you do, the interior becomes dusty quickly. In this situation, more factors come into play. For example, when was the last time you changed the cabin filter?

If you haven't changed it routinely, the filter is likely clogged. So, instead of filtering dust, it's redistributing it. Though, some cars don't have cabin filters. 

Here's a video demonstrating what it looks like to change one:

General Clothing And Items

Cars are convenient because they can carry more than a single person. They help us bring items from place to place. Some people even keep spare jackets and sweaters inside. So, it doubles as a temporary closet.

However, those items are likely causing the dust issue. Jackets and sweaters are more prone to release loose fibers. People can solve their dust issues completely by removing them from the area.

Passengers

The animals you ride along with also contribute to the problem. Even animals that don't appear to shed hair produce a dusty environment. So, you might want to get picky with who or what you let ride along. 

Activities That Produce Dust

Maybe you're the type of person that likes to sit in the car and eat. It's understandable. We can't hold on until we get home. 

So, you unpack the food from the drive-through and start consuming fries, burgers, etc. Unfortunately, no matter how much you try to keep it clean, crumbs will linger around. 

The more you do it, the more dust you produce for the interior. It's up to you to decide if it's worth the headache. Do you maintain a clean car or satiate your hunger right away? 

How Can You Make A Car Dust-Free?

To tackle the dust problem, you need to find the source. Once you eliminate the dust-producing items, you can maintain a dust-free car. 

As we've learned, that's nearly impossible with the outside of the car. If you drive frequently, there's no guaranteed way you can keep it dust-free. However, what if you rarely drive?

In that case, keep the vehicle in the garage. But don't let it sit there without a cover. This way, it reduces the exposure the car gets. 

Aside from that, there's not much you can do except frequent car washes. It's the only way to keep a clean look. There are some anti-static detailers on the market. 

However, the claims are shakey. More specifically, if it claims to repel dust, it's an unsubstantiated claim. At best, it can remove the static energy from the car's surface. So, dust is less likely to embed itself. 

It's up to you if you want to give them a try. 

Keeping the Car Interior Clean

It's a different case when you want to keep the car interior dust-free. You have more control over what goes in. However, some aspects are still out of our control. Cars aren't airtight. 

So, dust will manage to make its way inside in some capacity. In any case, you need to practice clean habits. You may need to carry around cleaning utensils. 

If your interior gathers dust quickly, inspect the items you keep inside. You will be surprised at how often some of them can shed. Of course, you'd also want to keep the interior isolated.

Keeping your windows closed most of the time can help with that. Some people would suggest reducing AC usage. However, that's unadvisable in some areas of the country. Who wants to drive in a hot car? 

Anti-static sprays can also help. Though, don't expect it to make a big impact. Dust will still settle all over the place. However, it won't lodge itself into the materials. So, it makes for easier cleanings.

How Often Should You Wash A Car?

Your car can get dirty at all times. Small things like bugs make it difficult to keep that initial shine after a car wash. Since it can get messy quickly, you might hold off longer between cleanings.

Is that a wise decision? It depends on the situation. Some people might not have a lot of time to set aside. In general, you should be washing your car every two weeks.

If you can't do it every two weeks, you can set it aside as a monthly chore. It's an adjustable situation. Though, it's worth noting that waiting too long between cleanings can leave lasting damage.

What Happens If You Wait Too Long to Wash Your Car?

Waiting too long in between cleanings can introduce problems you wouldn't be aware of. Dirt accumulates on the surface over time. It might not seem like a big deal initially.

But, it will continue to collect in specific areas. As the dirt accumulates, it begins to retain moisture. The water inside is enough to rust the metal body of the car.

That's not to mention how dirt embeds itself onto the surface. It's going to be tough to remove it the longer you wait. Sometimes, it can hold on well enough to chip the car paint.

The Finishing

Most cars come with a finishing over the paint and metal body. It's what helps them stay durable. Protective coatings like wax can last as little as eight weeks. So, once it wears off, the clear coating it sits over will wear off too.

Over time, it can turn from a simple dirt issue to a matter that requires repair services. In any case, the timing doesn't matter as much as the cleaning. As long as you do your best to maintain the car, it should last a long while.

How Often Should You Clean Your Car Interior?

The car interior is an area where cleaning can hold off longer. Generally, you should do a deep cleaning once a month. That's a general guideline.

There isn't a set rule on how often you should clean the interior. But, the longer you hold off, the more disgusting the car interior will look. It can even exacerbate your dust problems.

If you want to keep the inside as clean as possible, dust the interior weekly. Once you see problems that a simple dusting won't fix, do a deep cleaning. Practicing preventative measures can help your car look nearly as good as new.

Final Takeaway

Dust is a frustrating aspect of life. There's no way to stop it from settling on surfaces. Now you should know why it's an inescapable part of being a car owner. We all want our vehicles to look good, but that requires lots of care.
