Using this Billetworkz wiper fluid cap is easy. Just remove your old cap and screw on the new one tightly. When choosing a color for the anodized or powdercoated finish, pick one that matches your engine bay's style. As for maintenance, simply clean it with a mild soap and water solution from time to time to keep it looking great. Avoid using abrasive cleaners as they might damage the finish. Make sure to check the cap regularly to ensure it's still tightly sealed to prevent any fluid leaks.
