The best way to clean corroded rims off a car involves removing the corrosion and rust, aiming for a smooth surface, primarily through scrubbing.
Here's a breakdown of how to clean corroded rims:
Steps to Cleaning Corroded Rims
-
Initial Cleaning: Wash the rims thoroughly with soap and water to remove dirt, grime, and loose debris. This allows you to better assess the extent of the corrosion.
-
Corrosion Removal: This is the key step. Several methods can be employed:
-
Manual Scrubbing:
- Use a wire brush (brass or steel depending on the severity of the corrosion) to scrub the corroded areas. A brass brush is generally safer for painted or coated rims as it is less abrasive.
- Apply moderate pressure and scrub in a back-and-forth motion.
- This method is effective for light to moderate corrosion.
-
Chemical Treatment:
- Apply a rust remover or corrosion cleaner specifically designed for automotive wheels. Always follow the manufacturer's instructions.
- Allow the cleaner to dwell for the recommended time.
- Scrub the area with a brush or sponge.
- Rinse thoroughly with water.
-
Power Tools (For severe corrosion - use with caution):
- An angle grinder fitted with a knotted wire brush can be used for more aggressive corrosion removal. This method is only recommended for experienced users, as it can easily damage the rim if not handled properly.
- Wear safety glasses and gloves.
- Use light pressure and move the grinder continuously to avoid gouging the metal.
-
-
Sanding (Optional): After removing the bulk of the corrosion, you may want to sand the area to smooth out any remaining imperfections. Use progressively finer grits of sandpaper (e.g., 220, 400, 600) to achieve a smooth surface.
-
Final Cleaning and Polishing: Wash the rims again with soap and water to remove any residue from the cleaning or sanding process. Once dry, polish the rims with a metal polish to restore their shine.
-
Protection (Highly Recommended): Apply a wheel sealant or wax to protect the rims from future corrosion. This will help to prevent water, salt, and other contaminants from reaching the metal surface.
Important Considerations:
- Safety: Always wear safety glasses and gloves when working with chemicals or power tools.
- Rim Material: Different rim materials (e.g., aluminum, chrome, steel) may require different cleaning methods and products. Consult the manufacturer's recommendations.
- Finish: Be careful not to damage the rim's finish (e.g., painted, powder-coated, polished). Start with the least aggressive cleaning method and work your way up as needed.
- Professional Help: If the corrosion is severe or if you're uncomfortable performing the cleaning yourself, consider taking your rims to a professional detailing shop or wheel repair specialist.
By following these steps, you can effectively clean corroded rims and restore their appearance. Regular cleaning and protection will help to prevent future corrosion.
