  • Rinse the Boat: Begin by rinsing the entire boat with fresh water to remove loose dirt and salt deposits. Use a hose or buckets of water to thoroughly wet the surface.
  • Apply Cleaner: Using a soft sponge or brush, apply the chosen aluminum-safe cleaner. Work in sections to prevent the cleaner from drying on the surface.
  • Scrub Gently: Gently scrub the surface with circular motions. Pay extra attention to areas with oxidation or stains, but avoid aggressive scrubbing to prevent scratching.
  • Rinse Thoroughly: After scrubbing, rinse the boat thoroughly with fresh water to remove all residues of the cleaner.
  • Dry the Surface: Use a clean, soft towel or chamois to dry the surface. This prevents water spots and helps you inspect the boat for any missed areas.
  • Polishing (Optional): For additional shine and protection, apply an aluminum polish following the manufacturer’s instructions. Polishing also helps reduce oxidation buildup over time.

Dealing with Oxidation and Stains

Oxidation is a common issue on aluminum boats, appearing as dull, chalky, or white film on the surface. Stains from algae, bird droppings, or mineral deposits also require targeted treatment.

To remove oxidation:

  • Use a commercial oxidation remover designed for aluminum.
  • Apply the product with a soft cloth or foam applicator in small sections.
  • Allow it to sit for the recommended time, usually a few minutes.
  • Gently buff the area until the oxidation dissolves.
  • Rinse well to remove all residues.

For stubborn stains:

  • Identify the type of stain (organic, mineral, or grease).
  • Use stain-specific cleaners such as mild bleach solutions for algae or vinegar-based cleaners for mineral deposits.
  • Test any cleaner on a small, inconspicuous area first to ensure it does not damage the aluminum.
  • Avoid harsh scrubbing or abrasive tools.

Protecting the Aluminum Surface After Cleaning

After cleaning, protecting the aluminum surface extends the life and appearance of the boat. Applying a protective coating helps guard against oxidation, UV damage, and contaminants.
