Aluminum valve covers are a common problem for engine mechanics. The most common problem is corrosion and the discoloration from the oxidation process.

1. Clean the valve covers with a rag and water.

2. Polish the valve covers with aluminum foil.

3. Polish the valve covers with a piece of cloth (old t-shirt, for example).

4. Apply some wax to the valve covers to make them shine brighter.

5. Apply some carnauba wax to make them shine even brighter and last longer than just applying wax alone would do the job!

6. Use a paint brush to apply carnauba wax sparingly on the valve cover in circular motions, then wipe off excess wax with a clean cloth or paper towel.

7. Use an old toothbrush or other small brush to get into all of those tiny crevices and clean out any dirt that may have accumulated there over.
