How Does Road Salt Damage A Vehicle?

The corrosive nature of road salt affects various car components, making it crucial for drivers to be aware of the potential harm and take necessary precautions.

Here’s how road salt can damage a vehicle:

1) Corrosion

The primary concern with road salt is its ability to cause corrosion. When salt dissolves in water, it forms an electrolyte solution that can speed up the oxidation process, leading to rust on metal parts. The undercarriage, brake lines, exhaust system, and suspension components are particularly susceptible to this damage.

2) Paint Damage

Road salt can also harm your car’s paint job. As the salt accumulates on the vehicle’s surface, it can create small scratches or chips in the paint. These areas can become rustic if left untreated, compromising the car’s aesthetic appeal and resale value.

3) Electrical Components Damage

Salt and moisture can penetrate electrical connectors, causing corrosion and potential electrical malfunctions. This can lead to issues with various systems, such as lighting, sensors, and even engine performance.

4) Metal Fatigue

Prolonged exposure to road salt can weaken metal components over time, causing them to become more susceptible to fatigue and failure. This is especially concerning for critical parts like suspension and chassis, as it can impact the vehicle’s safety and performance.

5) Rubber And Plastic Components Damage

While not as susceptible as metal parts, road salt can also affect rubber and plastic components. Salt and grime can cause rubber seals and bushings to become brittle and crack, leading to potential leaks and reduced performance in suspension and steering systems.

Similarly, plastic parts like bumpers, trim, and underbody shields can become weakened and susceptible to damage.

6) Windshield And Windows Scratches

Salt and grit on the road can cause tiny scratches on your windshield and windows, impairing visibility and potentially compromising the structural integrity of the glass.

Moreover, salt residue can leave a hazy film on the glass, reducing visibility and making it difficult to see in low-light conditions.

7) Wheels Damage

Road salt can contribute to the corrosion of wheel rims and accelerate wear on tires. The salt can cause pitting on alloy wheels and eat away at the protective coating, while brine can seep into tiny cracks in tires, making them more prone to punctures and reducing their lifespan.

Useful Tips For Washing Car In The Winter Salt.

Washing your car in winter salt requires special care and attention to protect your vehicle from harsh elements. Here are some useful tips to help you effectively wash your car during the winter months:

  1. Choose a day when the temperature is above freezing (32°F or 0°C) to prevent water and cleaning solutions from freezing on your vehicle’s surface or crevices.
  2. Select a pH-neutral, non-abrasive car wash soap to wash road salt specifically designed for use during winter. This will help remove road salt, grime, and dirt without damaging your car’s paintwork.
  3. Before applying any soap, rinse your car thoroughly with water to remove any loose dirt, grime, and salt. This will help prevent scratches and swirl marks during the washing process and will keep your car clean.
  4. A microfiber wash mitt or soft sponge is ideal for cleaning your car’s surface without causing scratches. Work in small sections, starting from the top and moving downward, to ensure you don’t spread dirt and salt back onto already-cleaned areas.
  5. Road corrosive salt tends to accumulate on your car’s undercarriage, making it crucial to clean this area thoroughly. Use a hose or a specialized undercarriage wash attachment to spray away salt and grime.
  6. Salt and grime can cause damage to your wheels and tires. Use a dedicated wheel cleaner and a soft-bristle brush or wheel cleaning mitt to clean the wheels, paying special attention to the rims and lug nuts.
  7. Also, scrub the tires with a stiff brush to remove salt and dirt buildup.
  8. After washing your car, thoroughly rinse with clean water to remove any remaining soap, salt accumulation, grime and other harsh chemicals.
  9. Be sure to use a low-pressure setting on your hose to prevent damage to the paintwork. To avoid water spots and freezing, dry your vehicle using a microfiber drying towel or chamois, working from the top down and focusing on areas like door jambs, mirrors, and seals.
  10. Once clean and dry, consider applying a coat of wax or paint sealant to protect the paintwork from future salt exposure and make it easier to clean the next time. This extra layer of protection can help guard against scratches, corrosion, and fading.
  11. Road salt can also find its way into your car’s interior. Vacuum the floor mats and carpeting to remove salt and debris, and wipe down surfaces with a damp cloth or interior cleaner.
