Commercial trucks accumulate a specific and tenacious type of grime that light-duty car wash soap simply cannot address effectively. Diesel exhaust soot bonds to surfaces differently than road dust. Road film on highway trucks builds up in layers that water alone does not penetrate. Bug splatter on front panels and mudflaps bakes on during long hauls. Washing a working truck with a general-purpose soap means multiple passes, extended scrubbing, and results that look acceptable up close but still show the road film under good lighting.
Heavy Duty Truck Wash Quart from Polishing Systems Inc is the concentrated formula for this work. High-alkalinity chemistry cuts through diesel soot, layered road film, and grease deposits on contact, dramatically reducing the scrubbing time per vehicle and delivering a clean that holds up to a professional standard. The quart format is the right size for mobile detailers and small operations that need industrial performance without drum-handling logistics.
What Heavy Duty Truck Wash Is
This is a high-alkalinity concentrated truck and fleet washing detergent. High-pH alkaline chemistry excels at emulsifying petroleum-based soiling — diesel exhaust deposits, road oil, grease, and hydraulic fluid contamination — which are the primary soiling types on commercial trucks. It dilutes to create a working wash solution compatible with foam cannons, pressure washer injector systems, and bucket-and-brush hand washing. The quart size is the smallest working format in the Heavy Duty Truck Wash lineup, making it practical for mobile use and low-volume applications.
Key Features and Why They Matter
- High-alkalinity concentrated formula — effective against diesel soot, grease, and petroleum-based road film that light-duty soap cannot break down. Means measurably cleaner trucks in the same wash time, or the same cleanliness in fewer passes.
- Concentrated for dilution — the quart dilutes to multiple gallons of working solution. Means the per-wash cost is significantly lower than buying pre-diluted product and the quart goes much further than its volume suggests.
- Compatible with pressure washer foam injection systems — can be used through foam cannon and pressure washer detergent injection attachments for contact time and coverage efficiency.
- Works on trucks, trailers, and fleet vehicles — applicable to the full range of commercial vehicles including box trucks, flatbeds, tanker trailers, livestock trailers, and service vans.
- Quart portable format — easy to transport in a mobile detailing van or service vehicle without the bulk of larger containers.
What This Product Is NOT For
High-alkalinity truck wash detergent is not the right product for ceramic-coated vehicles — the high pH strips ceramic coatings over time. Do not use on freshly waxed vehicles where wax preservation is a priority. This product is also not appropriate as a wheel cleaner for uncoated aluminum wheels — the alkalinity can etch raw aluminum with repeated use. For aluminium wheel and trailer panel brightening, use an acid-based aluminum brightener. Not for interior use.
Who Uses This
Mobile truck detailers who wash commercial vehicles at client locations carry the quart format for flexible concentration control. Small fleet operators with 3-10 vehicles find the quart a practical supply for monthly wash cycles. Auto detailers who occasionally take on a truck or fleet vehicle order the quart to have the right chemistry on hand without buying a larger container. For higher-volume operations washing multiple trucks daily, the 1-gallon, 5-gallon, or 55-gallon drum sizes provide better per-gallon economics.
How to Use
- Dilute: Dilute according to soil level — typically 1:16 to 1:32 with water for standard truck washing. Use a stronger dilution for heavily soiled vehicles.
- Pre-rinse: Rinse the vehicle with high-pressure water to remove loose dirt and debris before applying detergent.
- Apply detergent: Apply diluted solution through a foam cannon, pressure washer injector, or brush-and-bucket method. Allow 1-2 minutes of dwell on heavy soiling.
- Agitate: For heavy road film and bug accumulation, agitate with a wash brush or sponge during dwell time.
- Rinse thoroughly: Rinse completely with clean water. Any detergent residue can streak or spot the surface when dry.
Why Heavy Duty Truck Wash vs. Consumer Car Wash Soap
Consumer car wash soaps are pH-neutral by design — they protect wax and sealants, which is the right chemistry for maintained passenger cars. Commercial trucks do not carry the same finish care requirements, and their soiling is several orders of magnitude heavier. Professional truck wash chemistry from Polishing Systems Inc is alkalinity-matched to the specific soiling profile of working commercial vehicles. The result is less scrubbing, faster rinse-off, and a cleaner final result per wash cycle than consumer soap can deliver on these surfaces.
Frequently Asked Questions
What dilution ratio should I use?
For standard truck washing with moderate road film, start at 1:20 with water. For heavily soiled trucks with diesel soot buildup and grease, use 1:10 to 1:16. Always dilute before applying — never apply concentrated product directly to painted surfaces.
Can I use this through a foam cannon?
Yes — Heavy Duty Truck Wash is compatible with foam cannon attachments on pressure washers. Use the foam cannon’s detergent ratio at a slightly higher concentration than bucket-and-brush application to allow for additional dilution through the foam cannon system.
Is this safe on vinyl wraps and graphics?
High-alkalinity detergents can degrade vinyl adhesives and edge-seal vinyl wraps over time with repeated use. For wrapped fleet vehicles, use a pH-neutral wrap-safe car wash soap instead. Test on an inconspicuous edge before using on full-wrap vehicles.
How much working solution does a quart make?
At a 1:20 dilution, one quart (32 oz) makes approximately 5 gallons of working solution — enough for 2-4 large truck washes depending on vehicle size and soil level.
Is a quart enough for a full truck wash?
Yes — at proper dilution, one quart of concentrate creates enough working solution for multiple full commercial truck washes. For daily or high-frequency fleet washing, the 1-gallon or larger sizes provide better economy.
