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

Aluminum boat trailers require more than a quick hose-down or traditional cleaning method. To avoid corrosion, it is important to get the right cleaner and follow the correct procedures. The first step is to hose off any debris, such as salt, dirt, or sand, to avoid rough abrasions. Then, apply an aluminum cleaner, let it soak, and scrub with a brush, starting from the bottom and working your way up. Rinse thoroughly and inspect to decide if a repeat is necessary. For hard-to-reach spaces, a toothbrush can be used. To make the trailer shine, polish it with a polishing ball and a few drops of metal polish. To reduce streaking, follow up with a second clean and dry cloth.

Rinse with fresh water after each use

Rinsing your boat trailer with fresh water after each use is an essential step in maintaining its longevity and ensuring it stays in top condition. This is especially important if your trailer has been exposed to salt, polluted, or brackish water, or if you've been travelling on salty roads.

The first step is to rinse your trailer with fresh water. This will help to remove any salt, dirt, or sand that may have accumulated during your adventures. It is important to get a smooth surface before moving on to the next steps. While this may seem simple, it is one of the most crucial stages in the cleaning process.

Next, you'll want to wipe away any visible scum lines around the hull waterline with a wet rag. Be sure to do this immediately after hauling the boat onto its trailer, as dried scum will be more challenging to remove and may eventually stain the hull.

After you've rinsed and wiped down the trailer, you can then begin to focus on the wheels. Regularly cleaning your trailer wheels with fresh water is essential, especially if you've been boating in salt or brackish water. This will help to ensure the longevity of your brakes and wheels.

Finally, don't forget to inspect your trailer after each use. Saltwater can be harsh on equipment, so it's important to keep a close eye on the condition of your trailer to catch any potential issues early on.

By following these steps and taking the time to properly care for your trailer, you'll be able to maintain its quality and appearance for years to come.

Use a brightening/polishing cleaner

Brightening/polishing cleaners are a great way to restore the original shine of your aluminium boat trailer. These cleaners not only clean the surface but also help to bring back the metal's original lustre.

To begin, you'll want to hose down your trailer to remove any debris, such as salt, dirt and sand, that may have accumulated. This is an important step to avoid scratches and scuffs during the cleaning process. Once you've hosed down the trailer, apply your chosen brightening/polishing cleaner. There are several options available on the market, including Aluma-Brite, Alumibrite, and Aluminox concentrate. You can also use a mixture of vinegar and water, or a product called Sonuus, which is great at removing corrosion.

After applying the cleaner, let the trailer soak for a few minutes. Then, using a brush, start agitating and removing any build-up. It's important to start from the bottom and work your way up. Take your time with this step, as it is crucial to achieving the desired results. For hard-to-reach spaces, use a toothbrush to ensure you get into all the crevices.

Once you've finished scrubbing, thoroughly rinse the trailer and inspect it to decide if a second round of cleaning is needed. If you're aiming for a shiny finish, you can add a few drops of metal polish and continue to polish. Finally, use a clean and dry cloth to buff your trailer, reducing streaking and enhancing the shine.

Remember, aluminium naturally fades over time, so regular cleaning and polishing with the right products will help maintain the quality and appearance of your trailer.

Use a cleaning/protecting cleaner

Aluminium boat trailers require more than a simple hose-down. To properly clean your aluminium boat trailer, you'll need to use a cleaning/protecting product and follow the correct procedures.

First, hose off any debris, such as salt, dirt and sand, to avoid rough abrasions that could lead to scratches and scuffs.

Next, apply your chosen aluminium cleaner. You can find these at janitorial supply warehouses, truck stops or automotive stores like NAPA. Products such as Aluma-Brite, Alumibrite, Aluminox, XPS Aluminum Cleaner, or a simple mixture of vinegar and water will do the job. Spray the cleaner on and let your trailer soak for a few minutes.

After soaking, use a brush to agitate and remove any build-up. Always start from the bottom and work your way up. Take your time with this step, as scrubbing is key to restoring your trailer. Once you're done, rinse thoroughly and inspect. If necessary, repeat the process. To reach hard-to-reach spaces, use a toothbrush.

Finally, follow up with a second, dry cloth to buff your trailer. This will reduce streaking and help you achieve a shiny finish.

Hose off debris to avoid rough abrasions

When it comes to cleaning an aluminium boat trailer, it is important to take the necessary steps to avoid any rough abrasions. The first step is to hose off any debris, such as salt, dirt, or sand, that may be present on the trailer from previous adventures. This is important because a rough surface can lead to scratches and scuffs during the cleaning process.

When hosing off the trailer, it is crucial to pay attention to detail and ensure that all debris is removed, making the surface as smooth as possible. This step may seem simple, but it is one of the most critical stages in the cleaning process. It lays the foundation for effective cleaning and helps prevent damage to the aluminium surface.

After hosing off the debris, the next step is to select an appropriate aluminium cleaner. There are two main types of cleaners to consider: brightening/polishing cleaners and cleaning/protecting cleaners. Brightening/polishing cleaners not only clean the surface but also restore the original shine of the aluminium, addressing any lackluster appearance. On the other hand, cleaning/protecting cleaners focus on stripping away debris and leaving a protective layer behind to extend the lifespan of the metal.

Once the cleaner has been applied, it is recommended to let the trailer soak for a few minutes. This allows the cleaner to work effectively and loosen any built-up grime. After soaking, use a brush to agitate and remove any remaining build-up, always working from the bottom of the trailer upwards. Take your time during this step, as it is crucial for achieving the desired results.

After scrubbing, thoroughly rinse the trailer with fresh water to remove any residue from the cleaning process. This step is important to prevent any cleaning solutions from damaging the aluminium surface over time. Once rinsed, inspect the trailer closely to determine if a second round of cleaning is necessary. Pay special attention to hard-to-reach spaces and use a toothbrush to access and clean those crevices thoroughly.

By following these steps, you can effectively clean your aluminium boat trailer while avoiding rough abrasions. Remember, maintaining the quality and appearance of your trailer is essential, and putting in a little extra time and effort will pay off in the long run.

Regularly grease your ball bearings

Regularly greasing your ball bearings is an essential part of maintaining your boat trailer. It is easy to overlook this task, as the wheel bearings are out of sight, but failure to do so can lead to accidents and damage to your boat. The wheel bearings are located inside the hubs on the trailer axle, and they allow the wheels to spin freely as you travel. The spinning motion generates friction and heat, so the bearings need to be lubricated to prevent them from overheating. This is done by filling the inner part of the hubs with grease.

To check and add grease to your trailer's wheel bearings, follow these steps:

• Remove the bearing protector cap.
• Check the grease level by pressing on the edge of the spring-loaded piston. If the piston moves, there is enough grease. If not, you need to add more.
• Mount a hand-pump grease gun to the grease fitting (grease zerk) in the centre of the piston. Pump in grease until the piston starts to move, then continue adding grease until the piston rocks approximately 1/8 inch when pressed.
• You can then jack up the trailer to spin the tire freely and help distribute the grease before towing.
• Wipe up any excess grease and replace the cap on the bearing protector.

It is recommended to grease your boat trailer wheel bearings at least once a year. However, if your trailer is regularly submerged in water, you should use grease that stands against saltwater. Additionally, you may want to invest in a bearing protector, such as the Bearing Buddy®, which helps prevent water from being pulled into the bearing seals.
