Step-by-step guide on how to clean an aluminum trailer

How to clean aluminum trailers


Begin by parking the aluminum trailer on a level surface and ensuring it's cool to the touch. Remove any loose debris like leaves or twigs.

Rinse with Water

Using a pressure washer or a hose, thoroughly rinse the entire trailer to remove loose dirt and grime. Pay attention to areas with heavy buildup, such as the undercarriage and wheel wells.

Prepare Cleaning Solution

Mix a mild detergent or specialized aluminum cleaner in a bucket with water according to the manufacturer's recommendations. Avoid using harsh chemicals that may damage the aluminum.

Apply Cleaning Solution

Use a soft bristle brush or sponge to apply the cleaning solution to the trailer's surface. Work in small sections, ensuring even coverage.

Scrub and Agitate

Gently scrub the aluminum surface, paying attention to areas with stubborn stains or oxidation. Agitate the cleaning solution to lift and remove contaminants effectively.

Rinse Thoroughly

Once scrubbing is complete, thoroughly rinse the trailer with water to remove the cleaning solution and loosen contaminants. Ensure all soap residue is washed away.

Inspect for Remaining Stains

Inspect the trailer for any remaining stains or spots. Repeat the cleaning process for persistent stains, or use a specialized aluminum brightener as needed.

Dry the Surface

After rinsing, use microfiber towels or a chamois to dry the aluminum surface thoroughly. This step helps prevent water spots and maintains the trailer's shine.

Apply Aluminum Polish or Wax

Once the trailer is dry, apply a quality aluminum polish or wax. Follow the manufacturer's instructions for the best application method. This step adds a protective layer to the aluminum and enhances its appearance.

Regular Maintenance

Implement a routine cleaning and maintenance schedule to prevent the buildup of contaminants. Regularly wash the trailer and reapply aluminum polish or wax as needed.

Additional Tips for Cleaning Aluminum Trailers

How to clean aluminum trailers

Avoid Abrasive Materials

Please refrain from using abrasive materials like steel wool or harsh brushes, as they can scratch the aluminum surface.

Check Seams and Joints

Inspect seams and joints for any signs of water infiltration. Address any potential issues promptly to prevent corrosion.

Protect Against Road Salt

If you live where road salt is used, regularly clean the trailer during winter months to prevent salt buildup, which can accelerate corrosion.

Use Aluminum-Friendly Products

When selecting cleaning products, ensure they are designed for aluminum surfaces to avoid damage.

Consider Professional Cleaning

Consider professional cleaning services specializing in aluminum trailer maintenance for heavily soiled or large trailers.

How do I protect my aluminum trailer against road salt during winter?

Protecting your aluminum trailer from road salt during the winter is crucial to prevent corrosion and maintain longevity. Follow these comprehensive steps to shield your trailer from the damaging effects of road salt:

Pre-Winter Inspection

Before winter sets in, conduct a thorough inspection of your aluminum trailer. Check for any existing corrosion, scratches, or areas of concern. Addressing these issues before winter will help prevent further damage.

Apply a Protective Coating

Before the winter season, apply a protective coating to the entire trailer, focusing on areas more susceptible to road salt exposure. Options include wax, polish, or specialized aluminum protective coatings. These coatings create a barrier, preventing salt from directly contacting the aluminum surface.

Regular Cleaning Routine

Implement a regular cleaning routine throughout the winter. Wash the trailer frequently, especially after exposure to road salt. Use a mild detergent or a specialized aluminum cleaner to remove salt deposits promptly. It would help if you also read How to Remove a Reference Code on Shein.

Undercarriage Protection

Pay special attention to the trailer's undercarriage, as this area is particularly vulnerable to road salt. Applying rust-inhibiting undercoating can provide additional protection against salt and other corrosive elements.

Fender and Wheel Well Care

Focus on the fenders and wheel wells, as these areas often accumulate road salt. Regularly clean and apply protective coatings to these regions to prevent salt buildup and potential corrosion.

Use Mud Flaps

Install mud flaps on your trailer to minimize the amount of road salt and debris thrown onto the trailer during travel. Mud flaps act as a protective barrier, reducing the direct impact of salt on the aluminum surface.

Avoid Salted Roads When Possible

If possible, plan your routes to avoid heavily salted roads. While this may not be entirely avoidable, choosing less salt-intensive courses can reduce exposure.

Store Indoors When Not in Use

Whenever possible, store your aluminum trailer indoors during the winter months. This provides the most effective protection against road salt. If indoor storage is not feasible, consider using a trailer cover to shield it from the elements.

Regular Inspections

Throughout the winter, conduct regular inspections of your trailer. Look for any signs of salt accumulation or corrosion. Promptly address any issues to prevent them from worsening.

Post-Winter Cleaning and Inspection

After the winter season, give your trailer a thorough cleaning to remove any remaining salt deposits. Conduct a detailed inspection to identify and address any corrosion or damage that may have occurred during the winter months.

By proactively applying protective coatings, maintaining a regular cleaning routine, and taking preventive measures, you can effectively shield your aluminum trailer from the corrosive impact of road salt during the winter, ensuring it remains in optimal condition for years to come.


Maintaining the cleanliness and integrity of your aluminum trailer is not just about aesthetics; it's about ensuring its longevity and optimal performance. By following this comprehensive guide, you can take proactive steps to remove contaminants, prevent corrosion, and enhance the visual appeal of your aluminum trailer.
