• Attach the Pressure Washer Soap Nozzle: After a fun day of sailing, get your boat to land and attach the pressure washer soap nozzle to the garden hose.
• Spray with Biodegradable Car Soap: Spray the boat starting from the bottom with biodegradable car soap and let it soak for about 5 minutes. Ensure it doesn't dry, as it will only add an extra layer of soap scum.
• Rinse Thoroughly: Rinse the boat from top to bottom using the pressure washer. Double-check to ensure that all detergent and dirt have been washed off the vessel, including the motor.
• Rinse Again with Clean Water: After pressure washing, give the boat a final rinse with clean water to remove any remaining detergent or debris.

By following these steps, you can effectively use a pressure washer to clean your aluminium boat, maintaining its appearance and performance. Remember to always be mindful of your surroundings and avoid pointing the pressure washer nozzle at yourself or others.

Use a cleaning solution designed for aluminium

Aluminium boats are prone to losing their shine and accumulating dirt on their hulls after continuous use. To restore the shine and brilliance of aluminium surfaces, you can use a cleaning solution designed for aluminium. Here's a step-by-step guide:

Step 1: Choose the Right Cleaner

Select a cleaner that is specifically designed for aluminium boats, such as Star Brite, Toon-Brite, or Marine 31. These products are formulated to remove grime, stains, and oxidation from aluminium surfaces without causing damage.

Step 2: Prepare the Solution

Follow the instructions on the chosen product carefully. Most aluminium cleaning solutions require dilution with water. For example, a common dilution ratio is 500 ml of aluminium cleaning solution to 1.5 or 2 litres of water.

Step 3: Put on Protective Gear

Before handling chemicals, it is important to take safety precautions. Put on protective gloves, footwear, goggles, and clothing to shield your skin and eyes from potential irritation or stains.

Step 4: Apply the Solution

Using a sponge, brush, or cloth, apply the prepared solution to the aluminium surfaces of your boat. Pay particular attention to areas with stubborn stains or oxidation, as they may require multiple applications or a steel wool scrub for effective cleaning.

Step 5: Scrub the Surface

Gently scrub the aluminium surfaces with a scrubber or a soft-bristled brush. If there are any patches of rust, address them immediately. However, avoid scrubbing too hard, as the affected area may be weak.

Step 6: Rinse the Boat

After scrubbing, thoroughly rinse the boat with water to wash away the chemicals. Refer to the product instructions to determine if the solution needs time to set in the metal layers before rinsing.

Step 7: Dry and Polish (Optional)

If you want to restore the shine of your aluminium boat, consider using a buffing chamois and buffing products after it has dried. Polishing will enhance the appearance of your boat and protect the aluminium surfaces.

Maintenance Tips:

To maintain the cleanliness and shine of your aluminium boat, consider the following:

• Regularly clean your boat, especially if it is frequently used or exposed to saltwater or polluted water, which can accelerate the buildup of dirt, algae, and marine life on the hull.
• Apply boat wax at least once a year to protect and enhance the appearance of your boat.
• Invest in a pressure washer, which can reduce cleaning time and effort.
• For bare, unfinished aluminium, be aware that it starts to oxidise as soon as it is manufactured. To prevent unsightly oxidation, apply protective coatings or treatments.

Avoid using corrosive or abrasive products

When removing wax from your aluminum boat, it's important to avoid using corrosive or abrasive products. While these products can effectively strip away the wax, they can also damage the underlying surface.

Aluminum boats are known for their toughness and resilience, but that doesn't mean they are invincible. Using abrasive products can scratch and damage the finish of your boat, compromising its appearance and protection. Corrosive products, such as strong acids, can also eat away at the metal, weakening the structure and making it more susceptible to damage.

So, what should you avoid? Stay away from harsh chemicals, strong solvents, and abrasive cleaning pads or tools. This includes products like steel wool, powdered abrasives, and industrial cleaners. Even some common household cleaning products can be too harsh for your boat. For example, products like Armor All, Formula 409, and certain waxes can damage the protective coating on vinyl surfaces.

When choosing a cleaning product, always read the label carefully. Look for something specifically designed for aluminum boats, as these products will be formulated to effectively clean without causing damage. Products like XPS Aluminum Cleaner or fiberglass cleaner are popular choices and can be used with a gentle scrubber to remove dirt and grime.

Additionally, always test any new product on a small, inconspicuous area of your boat before applying it to the entire surface. This will help you ensure that the product is safe and effective for your boat's specific finish. Remember, it's better to be cautious and avoid any potential damage that could be costly and time-consuming to repair.

By avoiding corrosive and abrasive products, you can effectively remove wax from your aluminum boat while maintaining the integrity and appearance of its surfaces.

Remove bird droppings and fuel splashes immediately

Bird droppings and fuel splashes can cause unsightly stains on your boat, so it's important to remove them as soon as possible. Here are some tips to help you deal with these messes effectively:

Bird Droppings:

Bird droppings can be challenging to remove, especially if they are left to dry and harden. To make the process easier, use a dedicated bird dropping remover like YachtGUARD Marine Spider and Bird Dropping Remover. This product is designed to quickly and easily remove bird droppings and stains from various surfaces, including fiberglass, aluminum, and painted surfaces. Simply spray it on the soiled areas, wait a few minutes for it to penetrate, and then wipe it off with a clean, damp cloth or sponge. For stubborn stains, you may need to cover the area with plastic to prevent evaporation and give it more time to work.

Another option is Aurora Boat Clean Plus, which can loosen up bird droppings. Apply it full strength, wait about 20 minutes, and then rinse. If the birds have left stains as well, use Aurora Boat Scrub to remove them. This product is also effective for cleaning non-skid decks.

To reduce the hassle of cleaning bird droppings, consider applying a protective coating like Aurora Sure Step. This pressure-sensitive polish seals the surface, preventing water and stain penetration. It also makes it easier to remove droppings, as a simple rinse with a garden hose may be sufficient if you get to the mess before it dries.

Fuel Splashes:

When dealing with fuel splashes on your boat, it's important to act quickly. Use a dedicated marine cleaner or degreaser that can break down fuel stains and oils. Look for products specifically designed for use on aluminum boats, as these will be safe for your boat's surfaces. Spray the cleaner onto the affected area, following the instructions on the product label, and then wipe it away with a clean cloth or sponge.
