DIY Trailer Wash: Best Practices and Common Mistakes

Keeping your trailer clean is crucial for its longevity and your safety on the road. At The Truck Wash, we understand that sometimes you might prefer to handle the job yourself. 

That’s why we’ve put together this comprehensive guide on DIY trailer washing. We'll cover the best practices and common mistakes to help you achieve the best results. So, let’s dive in and make sure your trailer shines like new!

Preparation is Key

Gather Your Supplies

Before you start, ensure you have all the necessary supplies. Here’s a checklist to get you started:

  • Water source: Hose or pressure washer

  • Buckets: At least two for soap and rinse water

  • Soap: A specialized vehicle soap

  • Brushes and sponges: Soft-bristled brushes and microfiber sponges

  • Degreaser: For tough stains and grease

  • Wheel cleaner: Specifically for your trailer’s wheels

  • Drying towels: Microfiber towels work best

  • Protective gear: Gloves and safety glasses

Having everything on hand before you begin will save time and ensure you don’t miss any crucial steps.

Choose the Right Location

Selecting an appropriate location for washing your trailer is essential. Ensure you have ample space to move around the trailer and access all sides easily. A shaded area is ideal to prevent soap from drying too quickly and leaving spots. Make sure the ground is level to avoid any accidents.

Importance of Deep Clean vs. Daily Clean

Understanding the difference between a deep clean and a daily clean is vital for maintaining your trailer. Daily cleaning habits help keep surface dirt and grime at bay, ensuring your trailer looks presentable and minimizing the buildup of contaminants. 

However, a deep clean is essential periodically to address areas that daily cleans might miss. Deep cleaning involves thorough scrubbing, degreasing, and attention to details like undercarriages and wheel wells, which helps prevent long-term damage and maintains the overall condition of your trailer. 

Incorporating both types of cleaning into your maintenance routine ensures your trailer remains in optimal condition and extends its lifespan.

The Washing Process

Pre-Rinse Your Trailer

Start with a thorough pre-rinse. This step is crucial for removing loose dirt and debris. Using a hose or pressure washer, rinse the entire trailer from top to bottom. Focus on areas with visible dirt accumulation, like the wheels and undercarriage.

Apply Soap and Scrub

Mix your vehicle soap according to the manufacturer’s instructions. Using your soft-bristled brush or sponge, apply the soap to the trailer. Work in sections to ensure the soap doesn’t dry before you can rinse it off. Start at the top and work your way down to prevent dirt from dripping onto cleaned areas.

Pay special attention to areas prone to grime buildup, such as the wheels, fenders, and the front of the trailer. For stubborn spots, apply a degreaser and let it sit for a few minutes before scrubbing.

Rinse Thoroughly

After scrubbing, it’s time to rinse. Use a hose or pressure washer to thoroughly rinse off all the soap. Ensure no soap residue is left, as it can cause streaking and spots. Work from top to bottom, just as you did when applying the soap.

Dry Your Trailer

Drying is an often overlooked but essential step in the washing process. Use microfiber towels to dry the trailer completely. This prevents water spots and streaks, leaving your trailer looking pristine. Pay special attention to crevices and joints where water can accumulate and cause rust over time.

Detailing for Perfection

Clean the Wheels

Wheels often require extra attention. Use a wheel cleaner specifically designed for your trailer’s wheels. Apply the cleaner and scrub with a soft-bristled brush. Rinse thoroughly to remove all cleaner residue. Dry the wheels with a microfiber towel to prevent water spots.

Polish and Protect

For that showroom shine, consider applying a polish to your trailer’s exterior. This not only enhances the appearance but also adds a protective layer against dirt and UV rays. Use a polish suitable for your trailer’s material and follow the manufacturer’s instructions.

Interior Cleaning

If your trailer has an interior, don’t forget to clean it as well. Vacuum the floors and upholstery to remove dirt and debris. Wipe down surfaces with a mild cleaner. For trailers used for transporting animals, ensure you disinfect the interior to maintain hygiene.

Common Mistakes to Avoid

Using the Wrong Soap

One of the most common mistakes is using dish soap or household cleaners instead of a specialized vehicle soap. These products can strip away protective wax and damage the trailer’s finish. Always use a soap designed for vehicles to ensure the best results.

Skipping the Pre-Rinse

Skipping the pre-rinse can lead to scratches and swirl marks as you scrub the dirt into the trailer’s surface. Always start with a thorough rinse to remove loose dirt and debris.

Overusing the Pressure Washer

While pressure washers are effective, using too much pressure can damage the trailer’s paint and seals. Use a pressure washer on a low setting or stick to a hose for a gentler clean.

Neglecting to Dry

Allowing your trailer to air dry can result in water spots and streaks. Always dry your trailer with microfiber towels to achieve a spotless finish.

Maintenance Tips

Regular Washes

Regular washing is essential to keep your trailer in top condition. Aim to wash your trailer at least once a month, or more often if you frequently drive on dirt roads or in harsh conditions.

Inspect for Damage

During each wash, inspect your trailer for any signs of damage, such as rust, cracks, or loose components. Addressing these issues early can prevent costly repairs down the line.

Protect the Finish

Consider applying a wax or sealant every few months to protect your trailer’s finish. This adds a layer of protection against dirt, UV rays, and other environmental factors.
