Aluminum Boat Care – Protect Your Boat from Corrosion

Aluminum boats are known for their durability and light weight, but even aluminum can corrode over time—especially in saltwater. Proper maintenance is essential to extend your boat’s lifespan. Here’s how to keep your boat in top condition.

1. Rinse with fresh water after every trip – Salt buildup is a major cause of corrosion.
2. Use mild cleaning products – Avoid harsh chemicals; use aluminum-safe soap and non-abrasive sponges.
3. Watch for galvanic corrosion – Keep dissimilar metals separated and ensure the right anodes are installed.
4. Replace sacrificial anodes regularly – Check and replace when half-worn.
5. Apply protective wax or coating – Prevents oxidation and adds a glossy finish.
6. Avoid steel-to-aluminum contact – Use rubber or plastic spacers to prevent electrical contact.
7. Inspect the electrical system – Faulty grounding can lead to electrolysis and corrosion.
8. Store in a dry, covered area – Protect from moisture and salt exposure off-season.
9. Repair scratches and dents quickly – Bare aluminum oxidizes fast. Touch up with primer and marine paint.
10. Follow manufacturer guidelines – Each model may have unique maintenance needs.
