What Is 2-Step Fleet Washing?

2-step fleet washing is a touchless method used to clean large vehicles like semi trucks, trailers, and buses. It involves two cleaning stages: an acid pre-rinse followed by a soap application. The chemical reaction between these two steps lifts road grime and allows for a clean rinse without scrubbing.

Why It Works So Well

Road grime is more than dirt — it’s a mix of minerals, oil, soot, and bugs. A single soap can’t tackle all of that. The 2-step method uses one product for inorganic grime and one for organic grime, allowing a full, deep clean.

How the 2-Step Process Works

Step 1: Acid Pre-Rinse

A light acid loosens tough build-up like road film and minerals. It’s applied quickly and rinsed before it dries. We only use acid blends that are safe for commercial truck surfaces.

Step 2: Alkaline Soap Application

This soap breaks down grease, bugs, and oil. It also neutralizes the acid. Together, they clean the truck from top to bottom.

Final Rinse

Clean water rinses away all chemicals and lifted dirt, leaving a clean finish with no damage.

Is the 2-Step Wash Safe for Polished Aluminum?

Yes — when done right. We use polish-safe, HF-free acids to avoid etching or streaking. Our team applies and rinses quickly to protect chrome, tanks, wheels, and decals.

What Equipment Is Used for 2-Step Fleet Washing?

• Commercial pressure washers – for high flow and safe PSI
• Dual soap injection systems – to apply both soaps accurately
• Low-pressure tips – to avoid damage on wraps and paint
• Water tanks and filtration – for mobile fleet jobs
