Cleaning Aluminum Boat Rails: A Step-By-Step Guide

Maintaining the shine on aluminum boat rails can be a challenge, especially when dealing with oxidation and corrosion. While some suggest using mild acid solutions or aluminum cleaners to eat through the oxidation, others recommend physical methods such as wet sanding, buffing, or polishing. It is important to exercise caution when using harsh chemicals and always wear protective gear. Products like Flitz, Nevr-Dull, WD-40, Sharkhide, and 3M are popular choices for restoring the shine on aluminum rails.

Using WD-40

To clean aluminum boat rails using WD-40, follow these steps:

Firstly, it is important to understand the benefits of using WD-40. WD-40 is a multi-use product that can clean and protect all the metalwork on your boat. Its moisture-displacing and penetrating properties make it an essential companion for boat maintenance. The product can be sprayed directly or onto a clean cloth, making it versatile and easy to use.

Now, to begin cleaning your aluminum boat rails, start by inspecting the rails for any deep scratches, gouges, or paint splatters. If there are significant scratches or paint marks, you may need to use a different method or product first to address these issues. However, for minor corrosion or dullness, WD-40 is an excellent choice.

Spray the WD-40 directly onto the aluminum boat rails, ensuring you cover all the areas you want to clean. You can also spray it onto a clean cloth and then wipe down the rails if you prefer a more controlled application. The product will help remove dirt, grime, mildew, and water marks, restoring the shine to your boat rails.

After applying the WD-40, use a clean cloth to wipe down the rails. You can also use the cloth to polish the rails, helping to buff out any scuff marks or minor imperfections. The WD-40 will not only clean but also protect the metal, maximizing the life of your boat rails and preventing rust.

Finally, if your boat has windows, you can also use WD-40 to keep them gliding open easily. Simply spray it onto the window tracks to clean away dirt and lubricate the sliding mechanism.

By following these steps and using WD-40, you can effectively clean and protect your aluminum boat rails, keeping them looking shiny and new.

Abrasive products

Another option is to use an abrasive polishing wheel, such as the Flitz buffing wheel that fits on a drill, which can be used with a polishing compound to quickly and easily restore the shine to aluminium rails. A similar product is the Mothers Power Ball, which is a foam pad that can be used with a polishing compound. For more intricate details, fine sandpaper can be used, starting with a lower grit for bigger scratches and working up to higher grits for a smooth finish.

It is important to note that if the aluminium rails are anodized, abrasive products should be used with caution as they can remove the thin anodized layer, leading to corrosion. In such cases, it is recommended to use a mild acid solution to remove oxidation and restore the shine. These solutions can be dangerous and require personal protective equipment such as rubber gloves, a respirator, and a protective suit.

Vinegar

To clean the rails, start by spraying the vinegar onto the oxidized areas. You may need to use a brush or cloth to apply the vinegar to hard-to-reach areas. Allow the vinegar to sit on the rails for a few minutes to let it start breaking down the oxidation. Then, use a soft cloth or sponge to scrub the rails gently. Rinse the rails with clean water to remove the vinegar and any loosened dirt or oxidation. For heavily oxidized rails, you may need to repeat this process a few times until the desired level of cleanliness is achieved.

It is important to note that vinegar may not be as effective as stronger acid solutions, and it may take longer to see results. Additionally, if the aluminum rails are heavily pitted or corroded, vinegar may not be able to remove all the corrosion buildup. In such cases, a stronger acid solution or mechanical polishing may be required.

After cleaning the aluminum boat rails with vinegar, it is important to dry them thoroughly to prevent water spots. You can use a soft cloth or a hairdryer set on low heat to ensure all the moisture is removed. Once the rails are completely dry, you can apply a coat of wax or polish to protect the surface and restore shine. Vinegar is a gentle and effective cleaner for aluminum boat rails, but regular maintenance and protection are necessary to maintain their appearance.

Polishing wheels

When using a polishing wheel, it is important to choose the right type of polishing compound for aluminum. There are compounds specifically designed for polishing aluminum wheels, while others are better suited for boat hulls. It is essential to select a compound that matches the type of aluminum being polished to avoid damage. General-purpose compounds usually contain finer abrasives that may be less effective at removing oxidation but are gentler on the metal.

Before using a polishing wheel, it is recommended to clean the aluminum rails with a mild acid solution or a simple paste made from baking soda and water. This will help remove any built-up dirt, grime, or oxidation. Additionally, masking the gel coat around the rails with tape can prevent damage to the surrounding areas.

When using a polishing wheel, always wear safety gear, including eye protection and gloves. Start with a coarse grit pad to remove any scratches or imperfections, and then switch to a finer grit pad to achieve the desired shine. With patience and effort, your aluminum boat rails can look new again.

For best results, it is recommended to consult a professional or refer to the manufacturer's instructions for the specific type of polishing compound and wheel being used.

Sharkhide

To use Sharkhide, set the adjustable nozzle to the finest mist possible and mist a 6' to 8' section from the bottom up. Let the foam work for a few minutes, then rinse it off. There is no need for scrubbing. The product will not harm carpeted bunks, paint, or decals.

Once Sharkhide is applied, it will begin to foam. Keep the surface under a thin blanket of foam for a few minutes, then rinse. After cleaning, you can apply Sharkhide's aluminium protectant or polish and then the protectant.

Customer reviews for Sharkhide are generally positive, with many customers finding the product effective and easy to use. It removes buildup and leaves aluminium shiny and clean. They appreciate its quick results and simple application process. Some customers have noted that it is important to follow the instructions carefully and wear proper protective gear when using the product.
