How to Protect Your Wheels from Corrosion
Repair Corroded Wheels - East Coast Coatings

Wheels are one of the most exposed parts of your vehicle, constantly subjected to harsh environmental conditions, dirt, and road debris. Without proper care, they can suffer from corrosion, which not only diminishes their aesthetic appeal but can also compromise their structural integrity over time. Protecting your wheels from corrosion is essential for maintaining their longevity and performance. In this guide, we’ll explore the causes of wheel corrosion and provide practical tips to safeguard your wheels effectively. 

1. Understanding Corrosion on Wheels 

What Causes Wheel Corrosion? 

Corrosion occurs when metal surfaces react with moisture, oxygen, and other elements, forming rust or oxidation. Alloy wheels, while more resistant to rust than steel, are still vulnerable to corrosion, especially if their protective coatings are damaged. Here are some common causes: 

  • Road Salt: During winter, salt is often used to prevent ice on roads. While effective for safety, road salt accelerates the corrosion process by reacting with metal surfaces. 
  • Moisture: Regular exposure to water, especially in rainy climates, can cause wheels to corrode over time, particularly if scratches or chips expose the bare metal. 
  • Brake Dust: Generated by braking, this fine dust contains metallic particles that can stick to wheels and react with moisture, leading to corrosion. 
  • Stone Chips and Scratches: Any damage to the wheel’s protective finish can expose the underlying metal, making it more susceptible to rust.

 

2. Regular Cleaning to Prevent Corrosion 

One of the simplest and most effective ways to protect your wheels is by keeping them clean. Dirt, brake dust, and road grime can trap moisture and accelerate corrosion, so regular cleaning is essential. 

Steps for Proper Wheel Cleaning: 

  1. Rinse Thoroughly: Use a hose or pressure washer to remove loose dirt and debris. Pay extra attention to the wheel wells and spokes. 
  1. Use a Dedicated Wheel Cleaner: Choose a non-acidic, pH-balanced wheel cleaner to prevent damage to the wheel’s finish. Spray it evenly over the wheels and let it sit for a few minutes. 
  1. Scrub with Soft Brushes: Use a soft-bristled wheel brush to gently scrub the surface and remove stubborn grime. For intricate areas, use smaller detailing brushes. 
  1. Rinse and Dry: Rinse the wheels thoroughly and dry them with a microfibre towel to prevent water spots. 

Tip: Clean your wheels at least once a month, or more frequently if you drive in harsh conditions. 

 

3. Applying Protective Coatings 

Protective coatings create a barrier between the wheel’s surface and the elements, reducing the risk of corrosion. 

  • Wax or Sealant: Apply a high-quality wheel wax or sealant after cleaning. These products form a hydrophobic layer that repels water, dirt, and brake dust, making it easier to maintain your wheels. 
  • Ceramic Coating: For long-lasting protection, consider ceramic coating. This advanced coating provides a hard, durable layer that resists scratches, chemical damage, and UV exposure. 
  • Powder Coating: If your wheels have significant wear or damage, powder coating is an excellent option. This process involves applying a tough, baked-on finish that protects against corrosion and enhances the wheel’s appearance. 

 

4. Avoiding Harsh Conditions 

While you can’t avoid driving altogether, you can minimise your wheels’ exposure to conditions that encourage corrosion. 

  • Rinse After Driving on Salted Roads: During winter, rinse your wheels regularly to remove salt and prevent it from settling on the surface. 
  • Avoid Puddles and Standing Water: Prolonged exposure to water can seep into small cracks and cause corrosion. Try to avoid driving through puddles whenever possible. 
  • Store Your Vehicle Properly: If your vehicle will be unused for extended periods, store it in a dry, covered area to protect the wheels from moisture and temperature fluctuations. 

 

5. Regular Inspection and Maintenance 

Inspecting your wheels regularly can help you catch and address minor issues before they escalate into significant corrosion problems. 

What to Look For: 

  • Scratches and Chips: Check for any damage to the wheel’s finish that could expose the metal underneath. 
  • Build-Up of Brake Dust: Accumulated brake dust can cause pitting and discolouration if left untreated. 
  • Signs of Rust or Oxidation: Early signs of corrosion, such as discolouration or surface rust, should be addressed immediately. 

What to Do: 

  • Repair Damage Promptly: Use touch-up paint or professional repair services to fix chips and scratches, restoring the protective coating. 
  • Polish the Wheels: Regular polishing can help maintain the shine and integrity of the wheel’s surface, while also removing minor imperfections. 

 

6. Professional Wheel Refurbishment 

If your wheels have already suffered significant corrosion, professional refurbishment can restore them to their original condition. Services like those offered by East Coast Coatings include removing the old finish, repairing damage, and applying a durable protective coating. 

Benefits of Professional Refurbishment: 

  • Thorough Cleaning and Repair: Professionals use specialised equipment to clean, sandblast, and repair wheels, ensuring all corrosion is removed. 
  • Customisable Finishes: Refurbishment allows you to choose from a range of finishes, such as powder coating, to enhance your wheels’ appearance and durability. 
  • Long-Lasting Results: With expert application, refurbished wheels are better protected against future corrosion, saving you time and money in the long run. 

 

7. Using Tyre and Wheel Protectors 

Wheel protectors, such as rim protectors and wheel covers, can provide an additional layer of defence against corrosion. These accessories shield the wheels from road debris, salt, and other contaminants, reducing the likelihood of scratches and chips. 

Types of Protectors: 

  • Rim Protectors: These are rubber or plastic strips that fit around the edges of your wheels, protecting them from kerb damage. 
  • Wheel Covers: Designed for steel wheels, these covers provide a barrier against dirt and moisture, keeping the underlying surface clean and dry. 

 

8. Avoiding Harsh Cleaning Products 

Not all cleaning products are suitable for alloy wheels. Harsh chemicals, acidic cleaners, or abrasive brushes can damage the protective coating, leaving the wheels vulnerable to corrosion. 

Tips for Choosing the Right Products: 

  • Use a non-acidic wheel cleaner designed specifically for alloy or steel wheels. 
  • Avoid wire brushes or harsh scrubbing pads that can scratch the surface. 
  • Opt for microfibre cloths and soft-bristled brushes for safe and effective cleaning. 

 

9. Benefits of Protecting Your Wheels 

Taking proactive steps to protect your wheels from corrosion offers numerous benefits: 

  • Extended Lifespan: Proper maintenance and protective coatings ensure that your wheels last longer, reducing the need for replacements. 
  • Enhanced Appearance: Clean, well-maintained wheels enhance the overall look of your vehicle, keeping it looking polished and professional. 
  • Improved Safety: Corroded wheels can weaken over time, posing a safety risk. Protecting your wheels ensures they remain structurally sound. 
  • Cost Savings: Preventing corrosion reduces the likelihood of costly repairs or replacements, saving you money in the long term. 

 

Conclusion 

Protecting your wheels from corrosion is essential for maintaining their appearance, performance, and durability. By following a regular cleaning routine, applying protective coatings, and addressing damage promptly, you can keep your wheels in top condition for years to come. For those dealing with existing corrosion, professional refurbishment services provide a reliable and effective solution. With the right care and attention, your wheels will remain as functional and stylish as the day they were installed.
