How to Clean Oxidation from Your Diamond Plate Trailer Floor

Aluminum diamond plate floors on trailers are durable and attractive, but they can lose their shine and develop oxidation over time due to exposure to the elements. Regular cleaning and maintenance are essential to keep the aluminum looking its best.

Aluminum diamond plate floors on trailers are not only resilient but also visually appealing. However, over time, they can lose their luster and become oxidized due to prolonged exposure to various environmental factors. To maintain the aluminum's aesthetic and prevent potential long-term damage, regular cleaning and upkeep are crucial. Below is a comprehensive step-by-step guide designed to help you effectively clean and restore the shine of your diamond plate trailer floor.

Why Cleaning Your Diamond Plate is Important:

  1. Aesthetic Appeal: Over time, aluminum can become dull and discolored due to dirt, grime, and oxidation. Proper cleaning restores its original shine, making your trailer look well-maintained.
  2. Prevent Corrosion: Regular cleaning removes contaminants that may accelerate corrosion, prolonging the lifespan of your trailer.
  3. Safety: A dirty or oxidized floor may become slippery, increasing the risk of accidents when loading and unloading your trailer.

Materials You’ll Need:

  • Warm water
  • Dish soap or mild detergent
  • Soft cloth or sponge
  • Baking soda
  • Vinegar or lemon juice
  • Non-abrasive scrub pad or soft-bristle brush
  • Towels or microfiber cloths
  • Aluminum polish (optional)
  • Protective gloves (optional)

Step-by-Step Cleaning Process:

  1. Preparation: Remove any loose dirt or debris from the trailer floor by sweeping or rinsing it off with water. This prevents scratches during the cleaning process.

  2. Basic Cleaning: Mix a solution of warm water and dish soap or mild detergent. Dip a soft cloth or sponge in the soapy water and gently scrub the surface of the diamond plate, paying extra attention to any heavily soiled areas. Be sure to clean in all the grooves and patterns of the diamond plate to ensure thorough cleaning.

  3. Rinse: After scrubbing, thoroughly rinse the trailer floor with clean water to remove all soap residue.

  4. Tackle Stubborn Stains: For tougher stains or tarnish, create a paste using baking soda and water. Apply the paste to the stains and scrub gently with a non-abrasive scrub pad or soft-bristle brush. Avoid using anything too abrasive, as this can scratch the aluminum surface.

  5. Oxidation Removal: If you notice white or gray powdery residue on the diamond plate (a sign of oxidation), mix a solution of equal parts vinegar or lemon juice and water. The acidic properties of vinegar and lemon juice are effective against oxidation. Soak a soft cloth in the solution and scrub the oxidized areas gently. For small areas, you can rub a lemon directly onto the surface.

  6. Rinse Again: Once the oxidation is removed, rinse the floor thoroughly with clean water to remove any remaining vinegar or lemon juice solution.

  7. Polishing (Optional): If you want to restore the shine of your diamond plate further, apply a commercial aluminum polish. Follow the manufacturer’s instructions for application. Use a soft cloth to buff the polish onto the surface, working in circular motions to achieve an even shine.

  8. Drying: Use a clean, dry microfiber cloth or towel to dry the diamond plate thoroughly. This will prevent water spots and help maintain the shine.

  9. Ongoing Maintenance: Regularly clean your trailer’s diamond plate floor to prevent dirt and oxidation buildup. If your trailer is exposed to harsh outdoor elements, consider applying a protective wax or sealant to reduce future oxidation and make cleaning easier.

Expert Tips:

  • Test Cleaning Products: Always test your cleaning solution on a small, hidden area before applying it to the entire surface to ensure it doesn’t damage the aluminum.
  • Avoid Harsh Cleaners: Do not use bleach, ammonia, or other harsh chemicals, as these can damage the aluminum and strip away its shine.
  • Prevent Oxidation: Regularly wash and dry the diamond plate to prevent oxidation from forming in the first place. Consider storing your trailer under cover to minimize exposure to moisture.

By following these steps, you can effectively remove oxidation from your trailer’s diamond plate floor and keep it looking shiny and clean for years to come.
