This warranty does not cover damage caused by abuse or regular wear and tear on brackets, plates, or mounting hardware.

Product Care & Maintenance:

  • Virgin Rubber: Clean the rubber portion of the mud flaps using a mild soap and water solution. Avoid harsh chemicals or petroleum-based cleaners, as they can degrade the rubber over time. Rinse thoroughly and let the mud flaps air dry for best results.
  • Anodized Aluminum:

    Anodized aluminum is a durable, corrosion-resistant material featuring a specialized coating that enhances protection against rust while providing an attractive finish. To preserve its appearance and functionality, appropriate cleaning methods are essential. Incorrect cleaning practices may compromise the coating, resulting in fading or pitting. This guide provides detailed instructions on maintenance, including routine procedures, advanced cleaning techniques, precautions, and considerations regarding touch-free car washes.

    Routine Cleaning and Preventive Maintenance

    Regular cleaning is necessary to prevent the accumulation of contaminants that could impair the surface. Employ non-abrasive methods to safeguard the thin protective layer.

      • Frequency: Perform cleaning every 3 months, or more frequently in environments with high pollution, proximity to coastal areas (where salt may accelerate corrosion), or high usage.
      • Basic Method:
        • Begin by rinsing with plain water to remove loose debris. Utilize a soft sponge or cloth for gentle wiping.
        • For minor soiling, prepare a solution of mild, pH-neutral soap (such as dish detergent) with warm water. Apply using a soft cloth, employing circular motions without excessive force.
        • Rinse thoroughly with clean water to eliminate any residue.
        • Dry the surface promptly with a soft towel to avoid water spots.
      • Tools: Select non-abrasive items such as soft-bristle brushes or cloths. Avoid steel wool or abrasive pads, as they may scratch and damage the coating.
      • Preventive Measures:
        • Apply a suitable protective wax or sealant designed for anodized aluminum following cleaning (e.g., automotive-grade waxes for vehicle parts).
        • In urban or industrial settings, monitor for acidic precipitation or organic deposits, which may etch the surface if not addressed promptly.
        • Store items indoors when feasible to mitigate ultraviolet fading of colored finishes.

    Deep Cleaning for Persistent Contaminants

    For significant buildup, such as oxidation or embedded grime, employ more intensive yet cautious approaches. Always test methods on an inconspicuous area first.

      • Mild Abrasive Methods: Form a paste with baking soda and water for gentle application with a soft cloth, followed by thorough rinsing. For oxidized sections, use fine-grit sandpaper (600-1000) lightly with water and polish afterward, though this should be infrequent to prevent thinning the coating.
      • Commercial Products: Select cleaners formulated for anodized aluminum with a neutral pH. Citrus-based options are suitable; refrain from using unverified household cleaners.

    Practices to Avoid

    Anodized aluminum is susceptible to substances that may dissolve or abrade its protective oxide layer.

      • Harsh Chemicals: Refrain from using strong acids (e.g., hydrochloric or phosphoric) or alkalis (e.g., sodium hydroxide), as they may cause etching, discoloration, or removal of the finish.
      • Abrasive Tools: Avoid vigorous scrubbing implements or polishes that could dull the surface and expose the base metal.
      • High-Pressure Washing: While suitable for initial rinsing, limit pressure to under 1,000 PSI to prevent intrusion into seams.
      • Environmental Exposures: Minimize contact with chlorine, fluoride, or heavy metals, which may induce pitting.

    Impact of Touch-Free Car Washes on Anodized Aluminum

    Touch-free car washes offer convenience and minimize paint scratches by employing high-pressure jets and chemical applications without physical contact. However, they may adversely affect anodized aluminum elements, such as trim or wheels, owing to the intensity of the processes and chemicals.

      • Potential Damage: These systems frequently utilize high-pH alkaline detergents and acidic pre-treatments that can interact with the coating, leading to discoloration, dulling, etching, or fading. Alkaline agents are particularly detrimental, potentially dissolving the layer and resulting in a chalky or pitted appearance. Repeated use may exacerbate issues, especially on colored anodizing, causing inconsistent hues or loss of gloss.
      • Risk Factors: The absence of mechanical brushing necessitates more potent chemicals and elevated pressures (up to 1,500 PSI), which may infiltrate seals or aggravate minor imperfections. Although generally compatible with standard automotive paint, these washes can deplete protective sealants on anodized components more rapidly.
      • Recommendations: Avoid touch-free car washes for items featuring anodized aluminum whenever possible, particularly those with high-alkaline formulations. Prefer manual washing with pH-neutral solutions. If utilization is necessary (e.g., for seasonal salt removal), rinse affected areas thoroughly afterward and apply a protective coating. Verify the chemical composition of the wash or conduct a test on a small section if gentler options are claimed.

    Common Harsh Chemicals in Touch-Free Car Washes

    Touch-free systems depend on robust chemical blends for effective cleaning without contact. These typically include:

      • Alkaline Detergents: High-pH (9-14) compounds such as sodium hydroxide or potassium hydroxide, which emulsify oils and grime but may etch anodized aluminum by eroding the oxide layer.
      • Acidic Pre-Treatments: Low-pH (2-5) solutions incorporating hydrofluoric acid, phosphoric acid, or citric acid to dissolve mineral deposits and salts. These can induce pitting or discoloration if not adequately neutralized.
      • Surfactants and Solvents: Components like volatile organic compounds (VOCs), glycol ethers, or petroleum distillates that facilitate cleaning but may include irritants capable of degrading seals and finishes over time.
      • Additional Agents: Chelating compounds, foam enhancers, or corrosion inhibitors intended for protection, yet potentially abrasive in elevated concentrations. Multi-step processes alternating acidic and alkaline applications heighten risks for sensitive materials such as anodized aluminum.

    These formulations prioritize efficiency and compatibility with paint, rendering them less ideal for specialized coatings like anodized aluminum.

    Effective maintenance of anodized aluminum requires consistent application of gentle, neutral cleaning agents to prolong its durability and preserve its attributes. By eschewing aggressive chemicals and abrasive techniques, irreversible damage can be averted. Although touch-free car washes provide convenience, their dependence on potent alkaline and acidic substances presents notable risks to anodized surfaces, potentially causing discoloration or deterioration—manual methods are preferable where feasible. In the event of damage, seek professional assistance for restoration. Adhering to these recommendations will ensure the material retains its optimal condition for an extended period.
