How to Clean a Enclosed Trailer

Whether you use your enclosed trailer for hauling cargo, dirt bikes, cars, transporting goods or camping adventures, keeping it clean is essential for both functionality and aesthetics. Over time, trailers can obviously accumulate dirt, dust, grime and other debris, which not only diminishes their appearance but can also lead to maintenance issues if left unaddressed. In this comprehensive guide, we’ll walk you through the step-by-step process of thoroughly cleaning your enclosed trailer—regardless of its size.

What materials are needed to clean?

Before you begin cleaning your enclosed trailer, gather the following materials:

  • Broom or vacuum cleaner
  • Soft-bristle brush
  • Mild detergent or soap
  • Bucket
  • Hose or pressure washer
  • Microfiber towels or soft cloths
  • Degreaser (if applicable)
  • Tire cleaner (if applicable)
  • Rust remover (if applicable)
  • Lubricant (such as silicone spray or WD-40)
  • Safety gear (gloves, goggles, etc.)

Step 1: Preparation:

Start by removing any items, equipment or debris from inside the trailer. This includes tools, furniture, camping gear or any other items that may obstruct the cleaning process. Sweep or vacuum the interior to remove loose dirt, dust and debris. Pay special attention to corners, crevices and hard-to-reach areas.

Step 2: Exterior Cleaning:

  • Rinse the exterior of the trailer with water using a hose or pressure washer. This helps loosen dirt and grime.
  • Prepare a solution of mild detergent or soap and water in a bucket.
  • Using a soft-bristle brush or sponge, gently scrub the exterior surfaces of the trailer with the detergent solution. Start from the top and work your way down to prevent streaking.
  • Pay close attention to areas with stubborn stains, grease or road tar. For tough stains, you may need to use a degreaser or specialized cleaner.
  • Rinse the trailer thoroughly with clean water to remove any soap residue.
  • If your trailer has tires, clean them using a tire cleaner and a brush. Rinse thoroughly afterward.
  • Inspect the exterior for any signs of rust or corrosion. If necessary, use a rust remover to treat affected areas.
  • Allow the trailer to air dry completely before proceeding to the next step.

Step 3: Interior Cleaning:

  • Inspect the interior of the trailer for any spills, stains or dirt buildup.
  • Prepare a mild detergent or soap solution in a bucket.
  • Using a soft-bristle brush or cloth, spot clean any stains or spills on the interior surfaces.
  • For general cleaning, use the detergent solution to wipe down walls, floors, and other surfaces. Pay attention to corners and seams where dirt tends to accumulate.
  • Rinse the interior surfaces with clean water and wipe dry with a microfiber towel or cloth.
  • If your trailer has built-up grease or grime, you may need to use a degreaser to remove it. Follow the manufacturer’s instructions carefully.
  • Once the interior is clean and dry, inspect for any signs of damage or wear, such as loose fittings or rusted metal.

Step 4: Maintenance and Protection:

  • After cleaning, consider applying a protective coating or wax to the exterior surfaces of the trailer. This helps repel dirt, water and UV rays, extending the life of your trailer’s finish.
  • Lubricate moving parts such as hinges, latches and wheel bearings with a silicone spray or WD-40 to prevent rust and corrosion.
  • Check the trailer’s tires for proper inflation and tread wear. Inflate as needed and replace any worn tires to ensure safe operation.
  • Store the trailer in a dry, well-ventilated area to prevent moisture buildup and mold growth.


By following these step-by-step instructions, you can keep your enclosed trailer clean, well-maintained and ready for whatever adventures lie ahead. Regular cleaning and maintenance not only prolong the life of your trailer—but also ensure safe and enjoyable hauling for years to come.
