How to Clean Your Boat Hull
Clean your boat hull in the following steps:
1. Remove Your Boat From the Water
Some professional boat cleaning services use scuba-diving equipment to clean boat hulls underwater. However, cleaning your boat hull on land is much safer and easier. Removing your boat from the water for cleaning is beneficial for the following reasons:
- Effective cleaning: Effective boat cleaning requires fresh water. You can scrub and rinse your boat hull with the fresh water it needs when you clean it on land. Cleaning your boat out of the water allows you to clean without corrosive saltwater in the way.
- Easier access: Cleaning your boat hull outside of the water allows you to see each barnacle and stain for easier removal. A professional diver may miss spots due to murky water.
- Safety: Cleaning a boat on land is much safer than underwater cleaning. While professionals are trained and skilled in diving, underwater cleaning often requires them to dive in polluted marinas and murky waters to reach a boat's hull. Diving in marinas presents risks of ear infections, and diving under a boat hull presents the risk of entrapment.
Use a boat trailer to pull your boat to an open area near a hose. Placing your boat near a hose allows you to rinse it easily.
2. Remove Debris and Stains
Boat hulls collect debris and substances such as barnacles, weeds, grease and slime. Rinse your boat hull thoroughly to remove debris and stains before cleaning. You may also need to scrub scum from the hull's surface with a soft bristle brush and spot clean with a cleaning solution. Removing particles from the hull's surface prevents corrosion when you scrub your boat clean in the following step.
3. Apply a Quality Cleaning Solution
After removing debris and stains from your boat hull, you can choose and apply a cleaning solution according to the solution's specific instructions. Some cleaning products may need to remain on the surface for several minutes before you rinse them, and some may require some scrubbing with a soft bristle brush or a sponge.
The right cleaning solution removes grease and stains without stripping the boat's surface materials to give your hull a radiant shine. Cleaning solutions with minimal chemical and acid content are safer for the environment. While cleaning your boat on land helps to prevent chemicals from entering the water, some chemicals can still flow down into the water or seep into the environment through the soil. Choose a cleaning solution that is safe for the environment to help protect natural land and resources.
It's also essential to choose a cleaning solution that removes grease and stains. Make sure your hull cleaner can clean your hull effectively. Many gentle boat surface cleaning solutions can completely remove dirt, slime, grease and particles without stripping your boat's surfaces.
The difference between learning how to clean an aluminum boat hull versus a fiberglass boat hull is choosing the right cleaning solution.

4. Rinse and Dry the Hull
After you leave your chosen cleaning solution on the boat hull for the recommended time, you can rinse it with fresh water. Use a hose to rinse away the cleaning solution, and check for any areas that require additional spot cleaning. Once all of the hull's areas are clean and rinsed, allow the boat to dry completely before moving on to the next step.
5. Apply Wax
Waxing is an important step after cleaning your boat hull. Applying wax to a clean, dry hull surface protects it from ultraviolet (UV) rays. Wax also creates a protective barrier between the hull's surface and the debris and scum that may cling to it when you return it to the water. Wax solutions such as Meguire Flagship Premium Marine Wax and Meguire One Step Cleaner Wax #50 are perfect for fiberglass and gel coat surfaces while Collinite Liquid Metal Wax No. 850 works great on metal boat finishes.
