Rust is one of the most common issues that car owners face, especially in winter. It begins with small spots and can spread rapidly, compromising your car’s structure and resale value.
Let’s see what causes rust in cars, how it affects your car, and how to stop rust from spreading in a car.
What is Rust?
Rust is a common term for iron oxide, and forms when iron reacts with oxygen and moisture.
In simple terms, rust is a result of a chemical reaction called oxidation. It is usually seen as a reddish-brown spot on the surface of the metal.
Why Are Cars Prone to Rust?
Cars are made from a variety of metals, including steel, an alloy of iron, and other elements. When this steel is exposed to the elements, rust formation is almost inevitable without proper care.
Exposure to Elements: Cars endure rain, snow, road salt, and humid air; all catalysts for rust.
Trapped Moisture: Hidden nooks and crannies in a car can retain water, speeding up the corrosion process.
Salt Damage: Coastal regions or areas with salted winter roads are particularly tough on cars, as salt accelerates rust formation.
Common Causes of Rust in Cars
Environmental Factors: Weather & Road Salt
If you live in an area with harsh winters, road salt is the major contributor to rust. It sticks to your car’s undercarriage and creates the perfect environment for corrosion.
Likewise, salty sea air can do the same for cars near coastal regions.
Poor Car Maintenance
Ignoring regular maintenance can significantly contribute to rust. Failing to wash your car regularly or neglecting to apply protective coatings can leave your car’s metal components exposed to the elements, quickening the rusting process.
Water Leaks and Trapped Moisture
Water leaks from poor sealing around windows or doors can lead to moisture getting trapped in your car’s interior. Over time, this trapped moisture can cause rust to form in the areas where you may not even see it until it’s too late.
How Rust Affects Your Car Over Time
What might seem like a small rust spot can cause bigger issues down the line if not addressed quickly.
Structural Concerns
Rust weakens metal, which can compromise the safety and durability of your car. Severe rust can affect critical components like the frame or suspension, making your car less safe to drive.
Impact on Resale Value
A rust-free car not only lasts longer but is also more valuable when you decide to sell it.
A car affected by rust is less attractive to potential buyers, and significantly impacts its resale value. Prospective buyers may wonder about the extent of the damage and the care taken in maintaining the car, making it harder to sell your car at a fair price.

How to Prevent Rust on Cars
1. Keep Your Car Clean and Dry
The first line of defense against rust is keeping your car clean.
Regularly wash your car to remove dirt, grime, and salt, especially during winter or after driving near the coast.
Focus on the undercarriage, wheel wells, and door frames where salt and moisture tend to accumulate. Always dry the car thoroughly with microfiber towels to prevent lingering moisture.
2. Wax your Car Regularly
Applying a layer of protective coat of wax after washing adds an extra layer of protection against moisture.
If you want to reduce the chances of rust forming on your car, apply high-quality wax every three to four months.
For longer-lasting protection, consider a ceramic coating, which can last up to two years.
3. Use Protective Coatings and Rust Inhibitors
Protective coatings and rust inhibitors, such as rust-proofing sprays, are designed to prevent rust from forming on metal surfaces and can be applied to the car’s undercarriage and other susceptible areas to prevent rust from spreading.
Products like WD-40 can also serve as rust inhibitors, providing a protective barrier against moisture.
Follow the instructions on the product as some products may have different application procedures.
4. Inspect and Repair Scratches and Dents Immediately
Scratches or dents expose the underlying metal to the elements, making it easier for rust to form. Regularly inspect your car for chips and repair them immediately to prevent rust from taking hold.
If you notice any small scratches that can be fixed by yourself, get a touch-up paint kit and start working on it.
For larger scratches or dents, it is recommended to get a professional car detailing service as delaying the process may cause more damage to your car.
5. Keep Your Car Covered
Whenever possible, park in a garage or use a high-quality car cover to protect your car from snow, rain, and debris. This reduces exposure to rust-causing elements.
6. Clean and Inspect the Undercarriage
The undercarriage of your car is particularly susceptible to rust because it’s constantly exposed to road debris and water.
Use a pressure washer to clean it thoroughly.
Inspect for early signs of rust and address them immediately.
7. Regular Inspections for Hidden Rust
Some areas of your car are more prone to rust than others, such as wheel wells, the underside of doors, and the trunk.
Hidden rust in these hidden areas can be tricky to detect. So, regularly inspect these hidden areas for early signs of rust and address them immediately to prevent further damage.
8. Address Water Leaks Immediately
Moisture is the main reason for rust to form in your car.
Water leaks, such as a faulty sunroof seal or windshield damage, allow moisture to accumulate inside the car, leading to rust and mold.
Additionally, if you see damp carpets or have a musty smell in your car but are not sure about where the water is coming from, consider taking your car to a mechanic to inspect it. Remember, water leaks not only cause rust but also lead to mold inside your car.
9. Using Rust-Resistant Car Accessories
Opt for rust-resistant car accessories, such as rubber mats and seat covers instead of stainless steel components. These accessories can help reduce the risk of rust formation, particularly in areas that are frequently exposed to moisture.
When to Seek Professional Help for Rust Damage
Sometimes, despite your best efforts, rust might spread to areas that require professional care.
Deep Rust Penetration or Frame Damage
If rust has penetrated deeply into the metal or affected the car’s frame, it’s best to seek professional help. Experts can assess the damage and recommend appropriate solutions, such as rust removal or part replacement for your car.
Extensive Damage
For extensive rust damage, consider full rust restoration services. Professionals use specialized tools and treatments to sand down the affected areas, apply rust treatments, and repaint your car to restore your car to its former glory.
While this can be costly, it’s a worthwhile investment to extend the life of your car.
Conclusion
Rust doesn’t have to be the end of the road for your car. With regular care and a bit of attention to detail, you can keep your car looking new and running smoothly for years to come.
