7. Maintenance

To ensure the longevity and appearance of your running boards:

  • Regular Cleaning: Wash the running boards regularly with mild soap and water to remove dirt, road salt, and debris. Rinse thoroughly.

  • Check for Damage: Inspect the running boards for any signs of damage, such as dents, scratches, or rust. Address any issues promptly to prevent further deterioration.
