- Test the product on a small, inconspicuous area first to check for adverse reactions.
Typical application involves applying the chemical cleaner with a soft cloth or brush, allowing it to sit for a specified time, then rinsing thoroughly with water. Repeat the process if necessary, but avoid overuse to prevent pitting or etching of the aluminum surface.
Mechanical Methods for Corrosion Removal
For more stubborn corrosion, mechanical methods such as sanding or polishing may be required. These techniques physically remove the oxidized layer to reveal clean aluminum beneath.
- Use fine-grit sandpaper (400-600 grit) to gently sand the affected areas.
- Progressively move to finer grits (up to 1500-2000) to smooth the surface.
- Employ a polishing compound and a soft buffing pad or cloth to restore shine.
Be cautious not to remove too much material, as aluminum wheels have a limited thickness and over-sanding can compromise structural integrity. Additionally, avoid aggressive power tools unless you are experienced, as they can easily cause damage.
Protective Coatings to Prevent Future Corrosion
After corrosion removal, applying a protective coating helps prevent recurrence. These coatings create a barrier against moisture, salt, and other corrosive elements.
Common options include:
- Clear coat paint: A durable lacquer that seals the aluminum surface.
- Wheel wax: A specialized wax formulated for wheels that repels water and dirt.
- Ceramic coatings: Advanced polymer coatings that provide long-lasting protection and enhance gloss.
Reapplication is necessary periodically, especially if the vehicle is exposed to harsh environments.
