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.
- Inspect Hardware: Periodically check all mounting bolts and hardware for tightness. Re-tighten as necessary to prevent loosening due to vehicle vibration.
- 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.
