6. Maintenance
Regular maintenance will ensure the longevity and appearance of your running boards.
- Cleaning: Wash the running boards regularly with mild soap and water to remove dirt, mud, and road salt. Rinse thoroughly and dry to prevent water spots. Avoid abrasive cleaners or harsh chemicals that could damage the black powder-coated finish.
- Inspection: Periodically inspect all mounting bolts and hardware for tightness. Re-tighten any loose fasteners to prevent rattling or instability.
