How to Spot Signs of Corrosion and What to Do About It


Owning a boat or waterfront property in South Florida is a dream for many, but it comes with its own set of challenges, such as the ever-present risk of corrosion. At Barnacle King, we're not just about keeping your hull clean; we're also committed to helping you maintain the integrity of your marine assets. In this blog, we'll guide you through spotting signs of corrosion and what steps you can take to address it.

What is Corrosion?

Corrosion is the gradual destruction of metal, often as a result of chemical reactions with the surrounding environment. In marine settings, this is usually accelerated due to the presence of saltwater, leading to galvanic corrosion.

Signs of Corrosion

  1. Discoloration: Look for areas where the metal has changed color, often to a reddish-brown or green.
  2. Pitting: Small, localized holes in the metal surface.
  3. Flaking: Layers of metal starting to peel off.
  4. Rust Stains: Reddish-brown streaks around metal parts.

How to Prevent Corrosion

  1. Regular Inspections: Our expert divers can conduct thorough inspections to identify early signs of corrosion.
  2. Zinc Anodes: These sacrificial anodes can protect your boat's metal parts by taking on the corrosion themselves.
  3. Quality Coatings: Use anti-corrosive paints and coatings for added protection.
