Deoxidizing Your Aluminum Boat: A Step-By-Step Guide

Aluminium boats are popular among boat owners because of their anti-corrosive properties. However, oxidation can cause the boat's appearance to deteriorate and even impact its function. To restore the boat's shine, a dedicated aluminium boat cleaner is required to cut through the layer of oxidation. This involves a three-step process: washing the boat with soap and water, cleaning it with an aluminium boat cleaner, and buffing it with aluminium polish. It is important to avoid using abrasive cleansers or solvents that could damage the finish of the boat. Additionally, it is recommended to clean aluminium boats on days that are not too hot, as direct sunlight can cause the metal to become too hot to handle.

Use a dedicated aluminium boat cleaner

Aluminium boats are great because the metal is highly resistant to rust, making it suitable for both salt and freshwater. However, aluminium has unique properties that require a special cleaning process.

Ordinary soap and water might clean the surface of the aluminium, but it won't restore its shine or protect the boat. This is because aluminium tends to develop an oxidised coating. Therefore, a dedicated aluminium boat cleaner is required to get through this coating.

There are many products on the market that are designed specifically for cleaning aluminium boats. These include:

• JJV's Best Aluminium Cleaner
• Napa Aluminium Brightener
• Zep-A-Lume
• Alumabrite
• Eagle Products' Mag Wheel Cleaner
• Super-chief AB-50
• Purple Metal Polish
• Alumabuff

When selecting an aluminium cleaner, make sure it's safe to use on boat hulls. Always carefully read the directions on the bottle before diluting the concentrate as directed.

Avoid abrasive cleansers

Aluminium boats are highly resistant to rust, but they do have a unique set of needs when it comes to cleaning and maintenance. One of the most important things to remember is to avoid abrasive cleansers.

Abrasive cleansers can damage the finish of your aluminium boat. The hull of an aluminium boat is typically made from a high-grade aluminium alloy with a corrosion-resistant finish. To preserve this finish, it's important to use the right cleaning products. Abrasive cleansers, such as solvents and powdered abrasives, can damage the hull and should be avoided. Instead, opt for mild detergents or dedicated aluminium boat cleaners, which are specifically designed to cut through the layer of oxidation that forms on aluminium.

In addition to abrasive cleansers, there are several other products that should be avoided when cleaning an aluminium boat. Harsh chemicals, waxes, and industrial cleaners can all damage the protective coating on the boat's vinyl and upholstery. Steel wool, scouring pads, and sandpaper should also be avoided, as they can scratch the surface and cause discolouration.

When it comes to removing oxidation from your aluminium boat, there are a few recommended methods. One option is to use a dedicated aluminium boat cleaner, which can effectively remove oxidation and restore the boat's shine. Another option is to use a buffing compound, such as Alumabuff, which can remove the damaged oxide surface without removing a layer of aluminium. This method is faster, cleaner, and more environmentally friendly than traditional sandpaper and rubbing compounds.

To prevent oxidation and maintain the appearance of your aluminium boat, it's important to establish a regular cleaning routine. Rinse the boat with fresh water after each use, especially if it has been exposed to salt or polluted water. Wipe away any visible scum or waterline stains with a wet rag, as these can become difficult to remove if allowed to dry.

In summary, when cleaning and maintaining your aluminium boat, it's important to avoid abrasive cleansers and products that can damage the finish and protective coatings. By using dedicated aluminium boat cleaners, mild detergents, and buffing compounds, you can effectively remove oxidation, preserve the boat's finish, and maintain its shine.

Rinse with fresh water after each use

Rinsing your aluminium boat with fresh water after each use is an essential step in maintaining the longevity and appearance of your boat. Here are some reasons why you should make it a habit:

Preventing Corrosion

Saltwater and other pollutants can cause corrosion on aluminium surfaces, leading to structural damage and costly repairs. Rinsing with fresh water helps to remove these corrosive elements and protect your boat.

Maintaining Performance

A clean boat hull reduces friction, allowing your boat to glide through the water more easily and improving fuel efficiency. By rinsing with fresh water, you can help keep your boat's hull free from dirt and grime, optimising its performance.

Extending the Boat's Lifespan

Regularly rinsing your boat with fresh water is a simple yet effective way to maintain its structural integrity. This practice helps to prevent rust and other damage, ensuring your boat stays in top condition for years to come.

Preserving Appearance

A clean boat not only performs better but also looks better. Rinsing with fresh water helps to remove dirt, scum, and stains that can build up over time, keeping your boat looking pristine and impressing your fellow boaters.

Removing Salt Deposits

Salt deposits can be particularly damaging to your boat, causing corrosion and abrasion. Rinsing with fresh water helps to dissolve and remove these salt crystals, protecting your boat's surfaces and paintwork.

Convenience

While it may not always be practical to give your boat a thorough wash after each use, a quick rinse with fresh water is a simple and convenient way to maintain your boat. It takes just a few minutes and can make a big difference in the long run.

Remove debris, dust and grease before applying a cleaner

Before applying a cleaning solution to your aluminium boat, it is important to clear off any debris, dust, or grease that has built up. This will ensure that the cleaning solution can work directly on the aluminium, resulting in a clearer finish and a more effective cleaning process.

Start by rinsing your boat with fresh water after each use, especially if it has been exposed to salt, polluted, or brackish water, or if it has been transported over salty roads. This will help to remove any loose dirt and debris. You can then use a wet rag to wipe away the visible scum line that forms around the hull waterline. Be sure to do this as soon as possible after hauling the boat onto its trailer, as dried scum will be more difficult to remove and may eventually stain the hull.

For more thorough cleaning, you can use a hose to spray down the aluminium surfaces and scrub the boat with a sponge soaked in hot water and car soap. If you encounter any problem areas that won't come clean despite vigorous scrubbing, you can try using steel wool or letting an aluminium cleaning solution tackle them in the next step.

If you are dealing with tough grime or grease, you may want to consider using a degreaser or a pressure washer equipped with the right pressure washing chemicals. However, always exercise caution when using a pressure washer, as high-pressure water can damage the boat's surfaces if not used carefully.

Remember, removing debris, dust, and grease is a crucial first step in the aluminium boat cleaning process. By taking the time to properly prepare the surface, you will achieve better results and make the overall cleaning task much easier.

Buff with a cloth or machine

Buffing is the final step in the process of cleaning an aluminum boat. It is important because it brings out the shine in the aluminum and protects it from the elements. You can buff your boat by hand or with a machine.

Buffing by Hand:

If you decide to buff your boat by hand, you will need a buffing cloth or pad and aluminum polish. Start by applying the polish to the cloth or pad. Then, press it onto the boat's surface and begin buffing in a circular pattern until you have covered all the aluminum. Remember to add more polish to the pad as needed. Keep in mind that buffing by hand can be time-consuming and labor-intensive, especially if the aluminum is heavily oxidized.

Buffing with a Machine:

If you want to make quick work of buffing your aluminum boat, using a buffing machine is your best option. Start by applying aluminum polish to the buffing pad while it is in motion. Then, press the pad into the aluminum and buff slowly from side to side, being thorough and ensuring you cover all the aluminum. You will need to add more polish to the pad as you work. Remember to inspect the pad periodically and remove any debris or buildup with a buffing rake.

Additional Tips:

• It is recommended to wear protective goggles and gloves when cleaning and buffing your boat to prevent the soap and aluminum cleaner from getting into your eyes and drying out your hands.
• Plan to clean and buff your boat on a day that is not too hot, as direct sunlight can heat the aluminum, making it too hot to touch.
• Place the boat on a trailer and park it in a shady spot with plenty of room for you to work.
• Before buffing, give your boat an initial wash with soap and water to remove loose dirt and debris, and follow up with an aluminum boat cleaning solution to ensure the aluminum is free of buildup.
• If you are buffing by hand, you can use a product like White Spirit to make the process easier. Mix one part White Spirit with four parts water in a spray bottle, spray it on the surface, and then apply the rubbing compound with a cloth in a circular motion.
• To avoid excessive abrasion, always remove all traces of the compound with a clean microfiber cloth after buffing.
