5. Maintenance
To ensure the longevity and appearance of your APS iArmor Nerf Bars, regular maintenance is recommended.
- Cleaning: The matte black powder-coated finish is designed for easy cleaning. Use mild soap and water with a soft cloth or sponge. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
