Cleaning Water Lines On Aluminum Boats: A Step-By-Step Guide

Keeping your boat clean is essential not only for preserving its appearance but also for protecting its value. In this article, we will discuss how to clean the water line off an aluminum boat.

Rinse with fresh water after each use

Rinsing your aluminium boat with fresh water after each use is a crucial step in maintaining its appearance and performance. Here are some detailed instructions and tips to ensure an effective rinse:

Timing and Frequency

• Rinse your boat with fresh water after each use, especially if it has been exposed to salt, polluted, or brackish water, or if you've travelled over salty roads.
• The longer you wait, the more challenging it becomes to remove scum and stains. Dried scum requires more effort to remove and, if left for too long, can eventually stain the hull.

Procedure

• Use a hose to thoroughly rinse the entire boat, paying close attention to the hull.
• Ensure that you rinse the boat from top to bottom, including the bottom of the hull.
• If you have access to a garden hose, you can use it to rinse off the boat before proceeding with a more comprehensive cleaning method.
• After applying a cleaning solution or soap, be sure to rinse the boat thoroughly to wash away the chemicals or soap. Double-check that you've rinsed all detergent from the vessel and flushed out the motor.

Precautions

• Always wear protective gear, such as gloves and eye protection, when handling cleaning chemicals or solutions.
• Avoid using abrasive cleansers, solvents, or harsh detergents, as these can damage the finish of your boat.
• Be cautious when using acid-based cleaners, as they can cause severe burns and damage clothing. Always follow the instructions and safety precautions provided by the manufacturer.

Wipe away visible scum lines with a wet rag

To clean the waterline off an aluminium boat, it is important to wipe away any visible scum lines with a wet rag. This is because dried scum requires more effort to remove and may eventually stain the hull.

To start, ensure you have a wet rag to hand. This can be as simple as a cloth soaked in water, or you can use a mixture of water and a mild detergent or a specialist aluminium cleaner. Specialist aluminium cleaners include XPS Aluminium Cleaner, Toon-Brite, and Star Brite. If using a specialist cleaner, be sure to wear protective gloves, footwear, goggles, and clothing to protect yourself and your clothes from stains.

Once you have your wet rag, simply wipe away the visible scum line. For stubborn patches, you may want to use a steel wool scrub. If you notice any rust, be sure to take care of it immediately, as it can spread throughout the hull. However, avoid scrubbing too hard as the area may be weak.

Clean with a mild detergent and warm water

To clean water lines off an aluminum boat, you can use a mild detergent with warm water. This method is recommended for both painted and unpainted hulls. Here is a step-by-step guide:

• Rinse your boat with fresh water after each use, especially if it has been exposed to salt, polluted, or brackish water.
• Immediately wipe away any visible scum line around the hull waterline with a wet rag after hauling the boat out of the water. Dried scum is harder to remove and may eventually stain the hull.
• For a deeper clean, use a mild detergent with warm water. You can also use a product specifically designed for cleaning aluminum, such as XPS Aluminum Cleaner. Avoid using abrasive cleansers or solvents that could damage the finish.
• Dip a soft cloth or sponge into the detergent solution and gently scrub the water line on the hull. Work in small sections to avoid streaking.
• Rinse the detergent and dirt off the boat thoroughly with fresh water. Ensure that you remove all the soap residue to prevent water spots and streaking.
• If there is still a visible water line, repeat the process or try a dedicated aluminum cleaner.
• After cleaning, you can apply a wax or sealant to protect the hull and make future cleaning easier.

It is important to note that you should avoid using harsh chemicals or abrasive cleaning tools on your aluminum boat, as these can damage the finish and weaken the hull. Always test any cleaning products on a small, inconspicuous area first to ensure they are safe for your boat's finish.

Apply wax and sealant to protect the finish

Once you have cleaned your aluminium boat, you will want to protect the finish to ensure it stays in top condition. Applying wax and sealant will help to preserve the original finish of your boat's painted hull surfaces.

To do this, you will need XPS Wax and Sealant, soft cloths, and a hose. You should follow the instructions on the wax and sealant product you are using, but as a general guide, you can follow these steps:

Begin by reading the instructions on the XPS Wax and Sealant carefully and preparing the solution. Most wax and sealant products will require dilution with water. Next, take a soft cloth and dip it into the wax and sealant solution. Apply the solution to the painted hull surfaces of your boat. You may want to use a different cloth to buff the solution into the hull, ensuring an even application. Finally, after the recommended time has passed, rinse the boat thoroughly with a hose to wash away any excess product.

You should aim to wax your aluminium boat at least once a year to maintain its appearance and value. It is best to apply boat wax one or two days after cleaning and ensure you avoid non-skid surfaces.

Use a pressure washer to reduce cleaning time and effort

A pressure washer is a handy tool for cleaning your aluminum boat, as it can reduce the time and effort needed. It is also useful for regular maintenance, helping you avoid an expensive cleanup after prolonged use.

Step 1: Get Your Boat to Land

After a fun sailing session, bring your boat to land. It is important to clean your boat regularly, especially after exposure to saltwater, polluted water, or freshwater with algae. These elements can cause discoloration and harmful bacteria to penetrate the hull, affecting your boat's performance.

Step 2: Attach the Pressure Washer Soap Nozzle

Attach the pressure washer soap nozzle to your garden hose. This nozzle will help you apply soap to your boat efficiently.

Step 3: Spray the Boat with Biodegradable Car Soap

Starting from the bottom of the boat, spray the entire boat with biodegradable car soap. Allow the soap to soak for about 5 minutes. Ensure that it doesn't dry, as this will create an extra layer of dirt and require more effort to clean.

Step 4: Rinse the Boat with the Pressure Washer

Now, it's time to rinse! Use the pressure washer to rinse the boat from top to bottom. Pay close attention to ensure that all the detergent and dirt are washed away. Don't forget to flush out the motor as well.

Step 5: Repeat if Necessary

If there are still some stubborn spots or water lines, you can repeat the process. The pressure washer will help loosen and remove any remaining dirt or stains.

Benefits of Using a Pressure Washer

Using a pressure washer for cleaning your aluminum boat has several advantages:

• Reduced cleaning time and effort: A pressure washer's high-pressure water stream quickly removes dirt, grime, and stains from your boat.
• Regular maintenance: By using a pressure washer for maintenance cleaning, you can prevent the buildup of dirt and grime, making future cleanings even easier.
• Efficient cleaning: The powerful spray of a pressure washer can reach tight spaces and crevices, ensuring a thorough clean.

In addition to using a pressure washer, there are a few other methods you can employ to keep your aluminum boat in top shape. These include using car soap for a gentle clean and aluminum cleaning solutions like Fiberglass Cleaner, Toon-Brite, or Star Brite for more intensive cleaning. Remember to always read and follow the instructions on cleaning products and wear protective gear when necessary.
