Fleet vehicle washing is one of the most overlooked niches in pressure washing. Companies with 10, 30, or 100+ trucks need them cleaned on a regular schedule -- and they're willing to sign contracts to make sure it happens. Less DIY competition, predictable recurring revenue, and per-job rates well above residential work. Here's how to price it and land accounts.

The Quick Answer

Fleet vehicle washing rates run $35-150 per vehicle depending on size and service type. Here's the pricing breakdown:

Cargo vans and box trucks: $35-65 per vehicle
Semi-truck cab only: $50-85 per vehicle
Full tractor-trailer combination: $80-150 per unit
Construction equipment (skid steers, excavators): $75-200 per unit
Volume discount for 25+ vehicles: 10-20% below standard per-unit rate

A single trucking company with 30 semis on a weekly wash contract is worth $4,200-6,000 per month. Land two or three accounts like that and you have a serious business.

Why Fleet Washing Is Different From Residential

Residential pressure washing is competitive, seasonal, and driven by homeowners who sometimes price-shop. Fleet washing runs year-round. Companies clean their vehicles for compliance, DOT inspections, brand standards, and driver morale -- not because spring arrived.

Most residential contractors don't pursue fleet accounts because they assume it requires specialized equipment or industry connections they don't have. That's not true. If you have a 4,000 PSI commercial machine and a trailer with a 300-400 gallon tank, you already have what the work requires.

Fleet Washing Pricing Models

Per-Vehicle vs. Flat Monthly Contract

Most operators start with per-vehicle pricing and move to flat monthly contracts once a relationship is established. Per-vehicle is easier to sell initially -- the fleet manager can calculate their cost and compare it to what they're paying now. Flat contracts are better for your cash flow because they lock in predictable revenue regardless of scheduling changes or missed weeks.

A typical arrangement for a 20-truck fleet at $55/truck = $1,100 per visit. At weekly frequency, that's $4,400/month from one account alone.

Frequency Pricing

Weekly and biweekly contracts should come with a per-vehicle rate that's 10-15% below your monthly or one-time rate. Here's why that works in your favor: weekly service means lighter grime buildup, faster cleaning per truck, and lower labor cost per unit. You earn more per hour even at the lower per-vehicle rate.

Weekly contract rate: $45-55 per semi cab
Biweekly contract rate: $50-65 per semi cab
Monthly contract rate: $60-85 per semi cab
One-time wash rate: $65-90 per semi cab

Small Fleet Premium

A 5-truck account pays more per vehicle than a 50-truck account. Your setup time, travel, and equipment staging are roughly the same regardless of fleet size -- so that fixed overhead gets spread across fewer units for small fleets. Set a minimum per-visit charge of $300-400 to protect your time on smaller accounts.

Equipment Requirements

Fleet washing burns through more water than residential work. A house wash uses 50-100 gallons. Cleaning 20 semi trucks in a row can consume 600-800 gallons.

Minimum setup for fleet work:

Pressure washer: 4,000 PSI / 4-5 GPM commercial gas unit
Water tank: 300-500 gallon poly tank on a dual axle trailer
Hose length: 200+ feet to reach vehicles parked at different positions
Downstream detergent injector: speeds up cleaning and reduces scrubbing on heavy grime

Hot water equipment cuts grease removal time by 35-40% compared to cold water. If you're targeting food distribution fleets, construction equipment, or restaurants' delivery vehicles, the $3,000-5,000 hot water upgrade pays off quickly in faster job times and better results on greasy surfaces.

How to Land Fleet Accounts

You're not competing on Google search here. Fleet accounts are won through direct outreach and in-person visits.

Who to Target

Local trucking and logistics companies: Industrial parks and commercial districts near highways are your starting point. Companies with 10-50 trucks are the sweet spot -- large enough for meaningful revenue, small enough to not need a national vendor.
Food and beverage distributors: Required to maintain clean vehicles for health compliance. High frequency = stable contracts.
Construction companies: Equipment needs cleaning after every job site. Lots of volume, typically less price-sensitive than residential accounts.
Delivery contractors (Amazon DSPs, FedEx contractors): Fast-growing fleets with ongoing cleaning requirements and standardized vendor processes.
Municipal and county fleet yards: Government contracts are competitive but recurring and almost never cancel.

How to Approach Them

Show up in person at fleet yards during business hours. Ask for the fleet manager or operations manager -- not the front desk. Bring a simple one-page rate sheet and a direct pitch: "We handle fleet washing on a regular schedule so your drivers don't have to deal with it."

Offer a free demo wash on 2-3 vehicles. Showing beats telling in this business. If the trucks come back clean and you showed up when you said you would, you're already ahead of most competitors. Consistency is the product.

Revenue Potential as a Solo Operator

Here's what a realistic fleet washing book looks like for a solo operator with one trailer rig:

Account 1: 30 semis, weekly at $55/truck = $6,600/month
Account 2: 15 box trucks, biweekly at $50/truck = $1,500/month
Account 3: 8 construction vehicles, monthly at $150/unit = $1,200/month
Total from 3 contracted accounts: $9,300/month

That's $9,300 in guaranteed monthly revenue before you book a single residential job. And fleet accounts tend to stick -- they don't cancel because a competitor put a door hanger on their door or because it rained last week.

Common Mistakes to Avoid

Underpricing to win the account. Fleet managers know what cleaning costs. If your rate is too low, it raises doubts about quality. Price fairly from day one and compete on reliability instead.

Not having a written contract. Always get the terms in writing: frequency, per-unit rate, cancellation notice period, and minimum monthly commitment. A handshake deal with a fleet manager who leaves the company leaves you with nothing.

Running out of water mid-job. Undersized tanks kill your reputation on fleet accounts. Know your run time per tank fill and have a fill plan for long jobs. A 300-gallon tank at 5 GPM gives you about 60 minutes -- enough for 15-20 vehicles at 3-4 minutes each.

Bottom Line

Fleet vehicle washing is a niche most pressure washing contractors overlook, which is exactly why the opportunity exists. Per-vehicle rates run $35-150, a mid-size fleet account generates $4,000-6,000/month, and the work runs year-round. You already have the equipment -- you just need to point it at a different type of customer.
