Keeping your truck clean isn’t just about aesthetics—it’s essential for vehicle maintenance, safety, and longevity. Regular cleaning prevents corrosion, paint damage, and visibility issues, all of which can impact performance and compliance.  

But when it comes to DIY truck cleaning, there’s a right way and a wrong way to do it. Using improper techniques or the wrong products can lead to costly damage and ineffective results. 

This guide covers the do’s and don’ts of DIY truck cleaning, helping you keep your vehicle in top condition while avoiding common mistakes. 

The Do’s of DIY Truck Cleaning

1. Use the Right Cleaning Products 

Not all cleaning products are suitable for trucks. Household detergents can strip protective coatings and damage paintwork. Instead, opt for commercial vehicle cleaning solutions designed to break down dirt without harming the finish. Check out our LPW Fleetcare shop for truck-friendly screen wash, traffic film removers, and pressure washers. 

2. Pre-Wash Before Scrubbing 

Before using a sponge or brush, rinse your truck thoroughly to remove loose dirt and debris. This prevents scratches and ensures a more effective clean. A foam lance or pressure washer is ideal for loosening grime before you start scrubbing. 

3. Clean from Top to Bottom 

Always start with the roof and upper sections before working your way down. This prevents dirty water from dripping onto already-cleaned areas, reducing streaks and improving efficiency. 

4. Use a Two-Bucket Method 

A common mistake is reusing dirty water, which can spread contaminants and cause scratches. The two-bucket method involves: 

  • One bucket for soapy water 
  • One bucket for rinsing your sponge or brush 

This simple technique keeps your cleaning tools dirt-free and prevents unwanted damage. 

5. Protect Your Paintwork 

After washing, apply a wax or sealant to protect the paint from UV damage, road grime, and water spots. This extends the time between washes and makes future cleaning easier. 

6. Pay Attention to the Undercarriage 

The undercarriage is exposed to road salt, mud, and grime, which can lead to rust if not properly cleaned. Use a pressure washer or undercarriage cleaner to remove buildup from hard-to-reach areas. 

The Don’ts of DIY Truck Cleaning 

1. Don’t Use Household Cleaners 

Dish soap, bleach, and other household cleaners may seem convenient, but they can strip protective coatings and cause long-term damage to your truck’s finish. Always use pH-balanced vehicle solutions designed for trucks. 

2. Don’t Wash in Direct Sunlight 

Washing your truck in direct sunlight can cause soap and water to dry too quickly, leading to water spots and streaks. Instead, clean your truck in a shaded area or during cooler parts of the day. 

3. Don’t Forget the Wheels and Tyres 

Your truck’s wheels and tyres are constantly exposed to brake dust, grease, and road contaminants. Neglecting them can lead to corrosion and reduce tyre lifespan. Use a wheel-specific cleaner and a stiff-bristled brush to remove buildup effectively. 

4. Don’t Use a Single Sponge for Everything 

Using the same sponge for all areas of your truck spreads dirt and grit, increasing the risk of scratches. Have separate cleaning tools for the paint, wheels, and undercarriage to maintain a spotless finish. 

5. Don’t Ignore Drying 

Air-drying your truck can leave streaks and water spots. Instead, use a microfibre drying towel or a leaf blower to remove excess water. This helps maintain a clean, streak-free finish. 

6. Don’t Overuse High-Pressure Washers 

While pressure washers are great for loosening dirt, using them too aggressively can damage paint, seals, and trim. Adjust the pressure settings and keep the nozzle at a safe distance to prevent damage. 

Professional Cleaning vs. DIY: When to Call the Experts 

Although DIY cleaning can be effective, professional truck washes offer deep cleaning and specialised treatments that go beyond what home methods can achieve. If your truck is heavily soiled, consider using a professional fleet cleaning service for a comprehensive clean.
