Between the 5-gallon pail and the 30-gallon drum lies the 15-gallon container — the format that fits operations too large for pail supply but not yet at the scale where full drum handling is the right answer. For fleet operations washing 15-40 vehicles per week, the 15-gallon format provides the supply interval of a larger container with the handling practicality of a mid-size container that can be managed by one person in a standard detail shop or maintenance bay.
High pH Soap 15 Gallon from Polishing Systems Inc delivers high-alkalinity commercial wash performance in this practical mid-size format. The same concentrated formula used in commercial truck washes and fleet programs, in a 15-gallon container that positions well for steady-use commercial detailing without drum investment.
What This Product Is
This is a concentrated, high-pH (alkaline) vehicle wash soap in a 15-gallon container. High-pH wash soaps are the correct chemistry for commercial vehicle washing where road film, diesel exhaust, traffic soiling, and petroleum contamination are the primary soil types. The concentrate dilutes to produce a large volume of working wash solution, and the 15-gallon format provides sustained supply for operations running regular fleet or commercial vehicle wash programs.
Key Features and Why They Matter
- High-alkalinity formula — breaks down petroleum-based road film and grease effectively on commercial vehicle surfaces. Means cleaner vehicles per wash cycle and reduced labor for difficult soiling removal.
- Concentrated high-dilution yield — the concentrate produces many times its volume in working wash solution. Means the per-wash cost is substantially lower than buying pre-diluted products at retail.
- 15-gallon container format — mid-volume supply that is manageable for a single-person handling in a standard maintenance bay or detail shop. Means the supply-management benefits of a larger container without requiring forklift or drum equipment.
- Compatible with foam and injection systems — works through foam cannons and pressure washer injection equipment for efficient large-surface coverage.
What This Product Is NOT For
High-pH wash soap is not suitable for ceramic-coated or freshly waxed vehicles where finish protection is the priority — alkaline chemistry degrades these protective layers. Not appropriate for uncoated aluminum wheels and trailer surfaces where repeated alkaline exposure can cause surface etching. For these surfaces and vehicle types, use a pH-neutral car wash soap. For operations needing more volume, see the 30-gallon and 55-gallon drum sizes.
Who Uses This
Mid-size fleet operators maintaining 10-30 vehicles on a regular wash schedule, commercial detailing businesses washing fleets and rental vehicles, and auto reconditioning shops that process multiple vehicles daily find the 15-gallon format matches their supply needs and handling capabilities. Larger mobile detailing companies that aggregate supply at a base location also use this size as their working supply container.
How to Use
- Dispense with pump: Use a hand pump or bung pump to pull concentrate from the container into a dispensing bucket or foam cannon reservoir.
- Dilute: Mix at 1:20 to 1:40 with water depending on soil level and application method.
- Pre-rinse vehicles: Remove loose dirt before applying detergent for most effective soil emulsification.
- Apply and dwell: Apply through foam cannon, injection system, or brush-and-bucket. Allow 60-90 seconds of contact on heavy soiling.
- Rinse completely: Rinse all surfaces with clean water until all detergent residue is removed.
Why This vs. Consumer Car Wash Soap at Scale
Consumer car wash soaps are pH-neutral and designed for protected paint surfaces in occasional use. Commercial vehicle washing at scale requires chemistry matched to the actual soiling — and alkaline chemistry is that match for petroleum-based fleet soiling. Commercial wash chemistry from Polishing Systems Inc is formulated for the performance and dilution economics that professional operations need.
Frequently Asked Questions
How many vehicle washes does 15 gallons of concentrate produce?
At a 1:30 dilution, 15 gallons of concentrate produces 450 gallons of working solution. At 1-3 gallons of working solution per vehicle wash, one container supports 150-450 vehicle wash cycles — several weeks of supply for most moderate-frequency fleet operations.
What dilution should I use for standard fleet cars?
For standard passenger fleet vehicles with moderate road film and traffic soiling, 1:30 to 1:40 is a practical starting point. For heavily soiled commercial trucks and service vehicles, 1:20 delivers stronger cleaning action. Adjust concentration based on results and vehicle type.
Is this safe on painted aluminum trailer bodies?
For painted aluminum, the high-pH detergent is generally safe at proper working dilutions for occasional washing. For uncoated or polished aluminum, use a pH-neutral detergent to avoid alkaline exposure effects over time. Always rinse thoroughly from all aluminum surfaces.
How should I store the 15-gallon container?
Store sealed in a cool, covered area away from freezing temperatures. The container should be kept upright and the closure secured firmly after each use. Mark with receipt date and use within the product shelf life for optimal performance.
Can I use this through a foam cannon attachment?
Yes — this concentrate is compatible with foam cannon attachments on pressure washers. The foam cannon adds its own dilution to the pre-diluted concentrate, so set your foam cannon’s soap ratio accordingly and account for the combined dilution when preparing your concentration.
