Fleet vehicles do not accumulate the same contamination as passenger cars. A semi-truck running interstate miles builds up layers of diesel exhaust soot, road oil, asphalt release agents, brake dust, and bird and bug impact that standard car wash soap is not formulated to address. When you wash a commercial fleet with a pH-neutral hand wash soap, you are doing the vehicle a favor visually but not removing the contamination that actually matters — the road film and grease that accumulate on frames, wheel wells, running boards, and lower panels on every trip.
Cuts Grease & Road Film Fleet Wash Soap 5 Gallon is high-pH concentrate formulated specifically for commercial fleet vehicles. The alkaline chemistry cuts through petroleum-based road film, grease, and heavy exhaust buildup that standard car wash chemistry cannot penetrate. At 5 gallons of concentrate, it provides the volume and dilution economy to wash a fleet daily without the per-vehicle chemistry cost making wash frequency a financial decision.
What This Product Is
This is a high-pH alkaline fleet wash concentrate. It works on the same principle as industrial degreasers — alkaline chemistry breaks down petroleum-based soils (grease, oil, diesel residue, road oil) by saponifying them, turning them water-soluble and allowing the rinse to carry them away. It is formulated at the balance point between heavy-duty effectiveness and paint safety — strong enough to remove road film from commercial vehicles, not so caustic that it immediately strips wax or attacks clear coat under normal wash dilution.
Key Features and Why They Matter
- High-pH alkaline formula — specifically designed for petroleum-based road soils and grease. Cuts contamination that neutral or low-pH chemistry cannot remove. Right chemistry for fleet work vs. standard car wash soap.
- Concentrated formula — high dilution ratio means 5 gallons of concentrate produces a significant volume of working wash solution. Per-vehicle cost at correct dilution is significantly lower than lower-concentration formulas.
- Effective on diesel exhaust soot — the alkaline formula penetrates and suspends the carbon-based soot that accumulates on commercial truck cabs, stacks, and rear panels from diesel combustion.
- Works on trucks, buses, and construction equipment — formulated for the contamination profile of heavy commercial vehicles, not passenger cars. One product handles the full commercial fleet range.
- 5-gallon working volume — the practical concentrate size for mid-size fleet operations. Large enough for meaningful volume purchasing, manageable without drum-scale handling equipment.
What This Soap Is NOT For
High-pH fleet wash soap is not for hand washing sensitive or freshly waxed passenger vehicles. The alkaline formula will strip carnauba wax rapidly and, at high concentration, can affect the gloss of single-stage paint. Use at correct dilution for commercial fleet work and reserve pH-neutral soaps for passenger vehicle maintenance washing. Do not use full-strength on painted surfaces. Not recommended for coated vehicles where ceramic or paint sealant preservation is important.
Who Uses This Product
Fleet maintenance facilities washing commercial trucks, buses, and utility vehicles on daily or weekly schedules. Construction equipment rental operations cleaning returned equipment. Municipal and government fleet maintenance departments. Transportation companies with internal wash bays. Any operation where commercial vehicle cleanliness is a practical maintenance requirement, not a cosmetic one.
How to Use
- Dilute correctly: Dilute per label recommendations for your application type. Fleet wash concentrate is typically used at 1:32 to 1:64 dilution in automatic wash systems; lower dilution for hand wash or high-pressure application on very dirty vehicles.
- Pre-soak for heavy contamination: For trucks with heavy road film, apply diluted product as a pre-soak dwell of 2-5 minutes before washing.
- Wash with brush or pressure wash: Agitate with a long-handled brush or apply through a pressure washer chemical injector for full coverage.
- Rinse thoroughly: High-pressure rinse completely, paying attention to wheel wells, steps, and undercarriage where product can pool.
- Inspect and repeat: Check for remaining road film on heavily contaminated areas. Repeat pre-soak or direct application if needed.
Frequently Asked Questions
What dilution should I use in an automatic fleet wash system?
Automatic systems typically operate at a high dilution ratio — 1:32 to 1:64 of concentrate to water in the wash arch. Consult your wash system’s chemical injection specifications and adjust based on vehicle contamination level and wash cycle time. Contact us for application-specific guidance.
Is this soap safe on aluminum truck bodies?
At proper dilution, this product can be used on painted aluminum truck bodies. Use with caution on raw, uncoated, or polished aluminum surfaces — high-pH chemistry can cause surface etching or discoloration on bare aluminum. Test on an inconspicuous area first, and rinse thoroughly after use on any aluminum surface.
Can I use this soap in a foam cannon?
Yes — at the appropriate dilution in a foam cannon reservoir (typically higher dilution than direct application to prevent foam cannon clogging), this concentrate produces good foam coverage for pre-soak treatment on heavy commercial vehicles.
How does this compare to a standard car wash soap?
Standard car wash soaps are typically pH-neutral formulations designed to clean without stripping wax or sealant. This fleet wash concentrate is high-pH, which is more aggressive on petroleum soils and appropriate for commercial vehicles that accumulate grease and road film. Using this on a freshly waxed passenger car would strip the wax — it is specifically for heavy-duty fleet work.
What other car wash soaps are available for different fleet types?
We carry a full range of car wash soaps from high-pH fleet concentrates to pH-neutral maintenance soaps, ceramic-safe wash soaps, and wash-and-wax combinations. Browse the car wash soap category or contact us for a recommendation based on your specific fleet type and wash system.
