Cleaning Aluminum Boats: Faqs For Sparkling Results

Aluminum boats are lightweight, easy to tow, and highly durable. However, they require regular cleaning and maintenance to prevent corrosion and maintain their appearance. This includes using the right cleaning products, such as aluminum brighteners and cleaners, and applying protective wax or polish to create a barrier against the elements. In this article, we will explore the best practices for cleaning and maintaining an aluminum boat, including choosing the right cleaning products, removing tough grime, and protecting your boat's finish. We will also discuss the unique properties of aluminum and provide step-by-step guides to help you achieve a clean, shiny, and well-maintained boat.

Removing algae and barnacles

To remove algae and barnacles from an aluminium boat, you'll need to clean it regularly. If you leave your boat in the water for long periods, you may need to clean it every 4-6 weeks.

First, rinse your boat with fresh water after each use, especially if it has been exposed to salt, polluted, or brackish water. Wipe away any visible scum line around the hull waterline with a wet rag after removing the boat from the water. Dried scum will be harder to remove and may stain the hull.

To remove algae and barnacles, you can use a pressure washer, or scrub the hull by hand. If you scrub by hand, wear gloves and use a hard plastic scrub pad or a scrubber. You can also use a mild detergent or a specialist aluminium cleaner like XPS Aluminium Cleaner, Toon-Brite, or Star Brite. Be sure to follow the instructions on the product.

If you're using a pressure washer, attach a soap nozzle and spray the boat with biodegradable car soap, letting it soak for about 5 minutes. Then, rinse the boat from top to bottom, ensuring you don't let the soap dry.

If you're scrubbing by hand, fill a bucket with warm water and detergent or aluminium cleaner, and scrub the hull with a scrubber or hard plastic scrub pad. You can also use steel wool to address tougher patches.

If you're dealing with barnacles, it's best to remove them while they're still wet, as they'll come off more easily. If they've dried out, you can try soaking them with CLR before pressure washing.

To prevent algae and barnacle build-up, you can apply a bottom paint or a hard Teflon paint to your boat.

Using car soap

Before you begin, ensure that the products you use are not harmful to any of the materials in your boat. It's also a good idea to remove any expensive electronics from the interior.

For this method, you will need a garden hose, a scrubber, biodegradable car soap, a bucket, and water.

Start by rinsing your boat with the garden hose. Then, fill the bucket with water and add car soap. Dip your scrubber into the soapy mixture and scrub down the boat's hull. Finally, rinse the soap and dirt off the boat thoroughly. If the hull is not clean enough, you can repeat the process or try a more intensive method.

If you want to keep your boat's paintwork shiny, it's best to avoid using dish soap or products like Lemon Joy, as these can dull the finish. Instead, opt for a quality car wash soap, and consider wiping down the boat with pledge after it's dry.

Acid-based cleaners

One acid-based cleaner that can be used on aluminum boats is hydrofluoric acid. This is a strong acid that is used in the trucking industry to clean aluminum. It can be effective at cleaning aluminum boats, but it must be diluted and used sparingly, as it can completely dull polished aluminum. It is important to take precautions when using this substance, as it is dangerous and can cause serious harm if it comes into contact with the skin or eyes.

Another option for an acid-based cleaner is muriatic acid, which can be purchased at hardware stores. This acid is often used to clean pools and can be effective at cleaning aluminum boats as well. However, it is important to note that muriatic acid is also a strong acid and can be dangerous if not handled properly. Always wear protective gear when working with this substance and ensure that the work area is well-ventilated.

There are also commercial acid-based cleaners available specifically for cleaning aluminum boats. These products are designed to remove oxidation and stains from aluminum boats and can be applied by brushing or spraying. It is important to follow the instructions on these products carefully and to take the necessary safety precautions, such as wearing rubber gloves and goggles.

In addition to acid-based cleaners, there are also non-acid options for cleaning aluminum boats, such as vinegar or specialized aluminum boat cleaners that are non-corrosive. These options may be safer and less damaging to the boat, but they may also require more elbow grease to achieve the desired results.

Pressure washing

Before pressure washing, it is important to remove all the items from the boat, such as life jackets and motors. You should also remove the drain plug to allow water to escape.

Firstly, get the boat to land and attach the pressure washer soap nozzle to a garden hose. Spray the boat from the bottom up with biodegradable car soap or a boat cleaner and let it soak for about 5 minutes. Ensure the soap does not dry as it will be harder to clean.

Next, rinse the boat from top to bottom using the pressure washer. Double-check that all the detergent has been washed off the boat and flush out the motor.

If there is still dirt on the boat, you can repeat the process. You can also use a brush or sponge to scrub the boat before rinsing it with the pressure washer.

After pressure washing, you can apply a thin layer of protective oil for aluminium hulls to the surfaces above the waterline. Spray the oil and wipe it with a dry cloth.

Protective wax or polish

After cleaning your aluminium boat, it is important to apply a protective wax or polish to create a barrier against the elements. This will help to maintain the boat's appearance and protect it from corrosion.

There are a variety of products available for this purpose, including XPS Wax and Sealant, Quickie Sauce wax, and Toon Brite. These products can be applied to painted hull surfaces to preserve the original finish and protect against UV damage.

When applying a protective wax or polish, it is important to follow the manufacturer's instructions. Some products may require dilution, while others can be applied directly to the surface. It is also important to ensure that the boat is thoroughly cleaned and dried before applying any protective coating.

In addition to waxes and polishes, there are also sealants available that can provide an extra layer of protection. Sealants can be applied over wax or polish to create a longer-lasting barrier against the elements.

It is recommended to apply boat wax at least once a year to maintain the shine and protect the aluminium surface. This will help to preserve the value of your boat and keep it looking its best.

By following these steps and using the right products, you can effectively protect your aluminium boat and maintain its appearance for years to come.
