How to prevent car rust

Quick insights

• Rust forms when metal, such as iron, comes into contact with oxygen and water in the air.
• You can prevent rust by regularly cleaning your car, waxing, applying a protective coating and getting consistent inspections of the undercarriage.
• By being proactive and addressing repairs in a timely manner, you can reduce the risk of rust forming on your car and ensure your vehicle remains in optimal condition.

Rust can sneak up on you, creeping into the nooks and crannies of your car. However, there are different ways to prevent rust on your car, but what is rust? Rust occurs when metal interacts with oxygen and water or moisture. These elements create a chemical reaction which results in the formation of oxide. This process is known as car rust damage and may threaten the longevity of your car, be unattractive and potentially reduce resale value.

To prevent rust, regular car maintenance is crucial such as washing and waxing your car. These tips could help minimize the chances of encountering severe car rust damage, enhance the physical appeal of your vehicle and maintain its resale value.

How does rust form on cars?

When metal comes into contact with oxygen and water, this causes a reddish-brown substance (rust) to build up on the metal surface. It typically starts off small, often in tiny chips where the metal is exposed. Environmental factors such as rain and road salt can speed up this process by providing extra moisture and chemicals that react with the metal.

The damage rust can cause

Rust can lead to cosmetic and structural damage, posing significant problems for vehicle owners. Rust can weaken the metal, causing it to crack and break more easily. This may compromise the car’s safety, leading to additional repairs or making the car unsafe to operate. Cosmetically, rust can detract from the car’s appearance and potentially lower its resale value.

How to prevent your car from rusting

You can significantly reduce the risk of rust damaging your vehicle through a combination of regular maintenance and protective measures. Winterizing your car is important to protect it from the harsh conditions of the cold temperatures, which can speed up rust formation. For instance, applying an undercarriage protectant can help protect your car against rust. The undercarriage of a car refers to the components underneath the main body. This usually includes the frame, suspension, exhaust system and drivetrain. Undercarriage protectant is a product or treatment designed to shield the undercarriage from damage caused by road debris, salt and other elements.

Wash your car regularly

It is recommended to wash your car regularly, especially after exposure to salt on the road. By washing your car on a consistent basis, you are removing harmful substances and reducing the opportunity for moisture to linger on the metal and kickstart the oxidization process.

Wax your vehicle

Applying wax to your vehicle every three to four months can help create a protective barrier against moisture and contaminants.

Apply protective coating

Protective coatings create a barrier that prevents moisture and chemicals from penetrating the metal surface. There are three types of protective coatings:

• Undercoating: Undercoating can protect against moisture and road debris.
• Clear coat sealants: Clear coat sealants can provide a barrier of protection against UV rays and pollutants.
• Wax and polymer sealants: Theses sealants can serve as a barrier over the paint, shielding it from contaminants and adding shine.

Keep an eye on the paint

If you notice any scratches or chips, touch up those areas to prevent the exposed metal from rusting. You can use manufacturer-approved touch-up paint to match the color of your car.

Protect your car from the elements

There are several strategies you can use to minimize exposure to environmental factors. Below are a few ways to prevent your car from rusting and deteriorating at a rapid rate:

• Park in covered areas: Whenever possible, try to park your car in a garage or covered parking area to protect it from direct sunlight, rain, snow and hail.
• Provide undercarriage protection: You can use undercarriage protectants to protect the vulnerable components underneath your car from road salt, moisture and debris.
• Maintain seals and weather stripping: It’s important to regularly inspect and maintain seals around doors, windows and the trunk to prevent water leakage into the interior.

Keep the interior clean

Clean any moisture or dirt that could lead to rust underneath your floor mats. The wear-and-tear from constant mat movement can lead to rust. Replace your floor mats at least once a year and use moisture-absorbing products such as silica gel packs.

In summary

Preventing rust on your car requires regular maintenance and consistent attention to detail. By washing your car on a regular basis, waxing, applying protective coatings and parking in covered areas, you can create barriers against moisture and environmental contaminants. By including these preventive measures into your car care routine, you can reduce the risk of rust forming on your car and preserve the integrity of your vehicle.
