How to Clean A Car Trailer?

Maintaining a clean car trailer is essential for its longevity and performance. Whether your trailer is made of aluminum or steel, regular cleaning can prevent corrosion, enhance its appearance, and ensure it functions properly. This guide will walk you through the steps to clean both aluminum and steel open car trailers effectively.

Prepare Cleaning Supplies

Before you start cleaning, make sure you have all the necessary supplies:

Pre-Rinse the Trailer

Start the cleaning process by giving your trailer a comprehensive pre-rinse, which is crucial for loosening and removing surface debris such as dirt, mud, and leaves. This step ensures that when you begin the more detailed cleaning, you aren’t just spreading grime around. Initiate the rinse by targeting the top of the trailer and systematically working your way down to the base. This approach allows gravity to assist in the cleaning process, pulling dirt and water down and off the trailer, which helps prevent redepositing dirt on areas you’ve already cleaned.

For particularly stubborn spots or heavily soiled areas, adjust your hose to a higher pressure setting to effectively break up the mud and grime. Make sure to cover every part of the trailer, including less accessible areas like the underside, wheel wells, and around the axles, which are prone to accumulating significant amounts of road debris. These areas are critical to clean thoroughly because built-up dirt can lead to rust and degradation over time.

As you rinse, pay close attention to corners, seams, and joints, which are common hiding spots for dirt and debris. Utilize different spray settings on your hose—if available—such as a fan or jet setting, to better dislodge and clear out compacted materials. However, be cautious around sensitive components like electrical wiring or bearing seals to prevent water damage or displacement. A thorough and careful pre-rinse sets the stage for a more effective wash and can highlight areas that might need special attention during the subsequent scrubbing phase.

Cleaning Aluminum Trailers

Aluminum trailers are known for their resistance to rust but still require proper cleaning to maintain their shine and prevent oxidation.

Mix the Cleaning Solution

Begin by preparing your cleaning solution. In a large bucket, mix water with a mild detergent or a cleaner specifically designed for aluminum. The concentration of the cleaner should follow the manufacturer’s recommendations, usually a few capfuls per gallon of water. This solution is effective at breaking down dirt and grime without harming the aluminum surface.

Scrub the Trailer

Start the scrubbing process from one end of the trailer and work your way to the other end. Use a soft-bristle brush to apply the cleaning solution, scrubbing in gentle, circular motions. This method helps lift dirt effectively without scratching the metal. Pay particular attention to areas where dirt or stains are more pronounced, such as wheel wells and areas around the axles where road grime accumulates. For stubborn stains, you might need to apply more pressure or use a stronger formulation of cleaner, but always test it on a small, inconspicuous area first to ensure it doesn’t damage the surface.

Rinse Thoroughly

After scrubbing, it’s crucial to rinse the trailer thoroughly with clean water to remove all traces of soap. Ensure that no soapy residues remain, as these can leave streaks or potentially damage the aluminum’s finish over time.

Dry and Polish

Once the trailer is fully rinsed, use microfiber cloths to dry it off completely. Microfiber is excellent for this purpose because it absorbs water well and reduces the risk of scratching the metal. After drying, apply a high-quality aluminum polish to enhance the shine and add a protective layer against the elements. Follow the instructions on the polish for the best results, using a clean, dry cloth to apply it in a circular motion. Allow the polish to haze over, then buff it off with another clean cloth until the trailer shines.

Cleaning Steel Trailers

When cleaning steel car trailers, several steps are essentially the same as those used for aluminum trailers, such as mixing the cleaning solution, scrubbing, and rinsing. However, there are crucial differences in the final steps and the focus of the cleaning process, primarily due to steel’s susceptibility to rust.

Mix the Cleaning Solution

Like with aluminum trailers, begin by mixing a mild detergent with water. However, for steel, consider a cleaner that includes ingredients to help prevent rust, if available.

Scrub the Trailer

Use a soft-bristle brush to thoroughly scrub the trailer. The method is similar to that used for aluminum trailers, but with steel, pay extra attention to any scratches or chips in the paint, as these areas are particularly vulnerable to rust.

Rinse Thoroughly

Rinse the steel trailer as you would an aluminum one, ensuring all soap and debris are washed off to prevent any potential for corrosion.

Dry and Polish

Drying is crucial for steel trailers to prevent water from sitting on the surface and leading to rust. After drying thoroughly with microfiber cloths, a critical difference comes in the form of protection. Apply a high-quality rust inhibitor or protective wax specifically designed for steel. This step is vital for safeguarding against moisture and pollutants that could lead to rust, which is a more significant risk with steel than with aluminum.

Emphasizing Rust Prevention

Unlike aluminum, which does not rust, steel requires additional protective measures. It is crucial to not only clean a steel trailer but also to protect it adequately from the elements. This involves regular inspections for any signs of rust, especially after exposure to moisture or salt (in coastal areas or during winter months). Any detected rust should be addressed immediately, often requiring more than just cleaning, such as sanding and repainting affected areas.

Inspecting for Damage

After cleaning, it’s crucial to inspect your trailer for any signs of damage. Look for rust spots on steel trailers or signs of oxidation on aluminum trailers. Address any issues promptly to prevent further deterioration. Use a rust converter or touch-up paint for steel trailers to cover any rusty areas.

Regular Maintenance Tips

Regular maintenance is key to keeping your trailer in top condition. Clean your trailer at least once a month, or more frequently if you use it often or drive in harsh conditions. Store your trailer in a covered area to protect it from the elements, or use a trailer cover if indoor storage is impossible. Regularly lubricate moving parts such as hinges and couplers to ensure smooth operation.

By following these steps, you can keep your car trailer in excellent condition, whether aluminum or steel. Regular cleaning enhances the appearance of your trailer and extends its lifespan, ensuring it remains a reliable asset for years to come.
