What You Should Know – Preventative Maintenance For Your Boat
Anodized Aluminum
The aluminum on your boat has been anodized. This creates a very hard protective seal on the surface of the aluminum to protect it as much as possible from pitting. When the anodized coating is broken and raw aluminum is exposed, corrosion will take place. Damage from chemicals, knives, gaffs, or other abrasive impacts can break the anodized coating.
Avoidable Corrosives
- Strong acidic solutions found in cleaners, paint remover, degreasers, etc.
- Concentrated alkaline based solutions. Many concentrated soaps fall into this category
- Chlorine, sulfurs, solvents, and ammonia-based products
Unavoidable Corrosives
- Saltwater (comes with the territory)
- Airborne pollution, particles from local sources: Vehicles, incinerators, paper mills, chemical plants, power plants, harsh chemicals from work performed at local shipyards and dry docks. Be aware of local sources that can expose your new boat to corrosive chemicals
How To Properly Clean
Always use a mild, non abrasive soap and lots of fresh water. Thoroughly wash the aluminum with a soft towel or sponge utilizing lots of soap and water to remove all dried salt crystals and other contaminants. Rinse completely with direct water pressure. The important point is to clean and rinse it well!
