Cleaning polyurethane fender flares is straightforward and similar to washing the rest of your vehicle’s exterior. Regular washing with mild soap and water is usually sufficient to remove dirt, mud, and road grime. A soft cloth or sponge should be used to avoid scratching the surface. For more stubborn dirt or tar, a dedicated automotive cleaner or degreaser can be used, followed by a thorough rinse.
To maintain their appearance and longevity, applying a UV protectant or a polymer sealant periodically can be beneficial. These products help to prevent the polyurethane from drying out, fading, or becoming brittle due to sun exposure. Many car detailing products designed for plastics and rubber will work effectively. Avoiding harsh chemical cleaners or abrasive pads will ensure the flares remain in good condition and retain their intended look and protective qualities for years to come.
