Most pressure washing contractors spend all their time chasing one-off residential jobs. Meanwhile, the operators pulling in steady monthly income are landing fleet accounts -- contracts with trucking companies, delivery fleets, and construction firms that pay thousands of dollars every single month without the marketing grind.

The Quick Answer

Commercial fleet vehicle pressure washing pays more per day than residential and comes with recurring contracts. Here's what you can charge per unit:

Cargo vans and light commercial: $15 - $40 per vehicle
Box trucks and medium-duty delivery: $35 - $65 per vehicle
Semi truck cab only: $50 - $85 per unit
Full tractor-trailer combo: $60 - $150 per unit
Heavy construction equipment: $150 - $270+ per unit

A 30-truck weekly contract at $35 - $65 per truck generates $4,200 - $6,000 per month in recurring revenue -- that's $50,000 - $72,000 per year from a single client.

Who to Target for Fleet Contracts

The best fleet washing clients are companies with branded vehicles on the road every day. Dirty trucks hurt their reputation. That's your pitch.

Long-haul trucking and logistics: Largest volume segment, most consistent need
Delivery fleets: Amazon DSP contractors, food distributors, regional carriers
Ready-mix concrete companies: Extremely dirty trucks, often weekly washes required
Construction contractors: Excavators, dump trucks, and graders at $150 - $270 per piece
Waste management fleets: High soil loads, regular service every one to two weeks
Municipal fleets: Public works, school buses, police -- stable government contracts with predictable billing

Drive through industrial areas and distribution hubs. If you see dirty trucks with a company logo, that's a cold call lead.

How Often Fleet Vehicles Get Washed

Washing frequency determines your monthly revenue per account. There's no federal requirement -- it's driven by industry norms and how dirty the trucks get.

Weekly: Ready-mix concrete, waste management, high-mileage delivery fleets
Biweekly: Standard semi-truck fleets and logistics companies -- the most common contract structure
Monthly: Light commercial vehicles, low-mileage company fleets, seasonal equipment

Biweekly is the sweet spot. You're charging a higher per-wash rate than weekly but maintaining a consistent recurring schedule. A fleet on weekly service generates 4x the monthly revenue of one on monthly service.

Equipment Requirements for Fleet Work

This is where fleet washing differs significantly from residential. Standard residential equipment will burn out your operator and leave trucks looking half-clean.

GPM Matters More Than PSI

The target for fleet washing is 8 GPM at 3,000 PSI. Most residential operators run 2 - 4 GPM machines. A 4 GPM machine will wear your operator out in two hours on a fleet account. Volume throughput is what keeps you profitable.

Hot Water Is Required for Diesel Trucks

Cold water cannot effectively remove diesel exhaust deposits, axle grease, or engine bay buildup without excessive scrubbing. Hot water at 180 - 210 degrees F emulsifies grease and cuts cleaning time from 90 minutes to 30 minutes per truck. Any trucking, construction, or oil-field client requires a hot water unit. Budget $3,500 - $6,000 for a commercial-grade machine.

Water Reclaim Systems

This is not optional for most commercial accounts. The EPA Clean Water Act prohibits wash water containing oil, grease, and detergents from entering storm drains. Fines hit $25,000 per day per violation. A closed-loop reclaim system collects and filters wastewater on-site. Large fleet clients will require proof of wastewater compliance before you set foot in their yard.

How to Land Your First Fleet Account

Fleet managers buy based on reliability, compliance, and cost per unit -- not the same pitch that works on homeowners. Here's the sequence that works:

Find your prospects. Drive industrial areas, logistics parks, and distribution zones. Dirty branded trucks equal leads.
Get to the right person. Ask for the fleet manager, operations manager, or yard supervisor. Skip the front desk.
Lead with their pain points. DOT inspection windows, brand image on the road, corrosion prevention from road salt and diesel residue.
Offer a pilot wash. Clean 5 - 10 trucks at a discounted rate with before-and-after photo documentation.
Close on a service agreement. Propose a 6 or 12-month contract with monthly billing and a locked schedule.

Show up when fleet managers gather: chamber of commerce events, logistics industry breakfasts, and construction association meetings. Relationships close these accounts -- not ad campaigns.

Insurance Requirements

You will not get on a commercial property without a certificate of insurance. Fleet accounts require more coverage than residential work:

General Liability: $1M - $2M per occurrence, $2M - $3M aggregate minimum
Commercial Auto: Required for your truck and trailer
Workers' Compensation: Required in most states the moment you have employees
Pollution Liability: Covers chemical runoff incidents not included in standard GL policies

Have your COI ready to email within 24 hours of being asked. Large clients specify coverage minimums in their vendor agreements -- know your numbers before the meeting.

What the Revenue Looks Like

A solo operator washing 15 - 20 trucks per day at $65 per truck earns $975 - $1,300 gross daily. At 40 - 50% margins, that's $400 - $650 net per day. Compare that to chasing residential driveways at $150 each and the math is clear.

The global fleet washing market hit $21.8 billion in 2024 and is growing at 6.7% annually. This is not a niche with a ceiling -- it's a niche with a growing floor.

The tradeoff is a higher upfront investment in equipment ($5,000 - $15,000 for a proper fleet washing setup versus $1,000 - $3,000 for residential). But the payoff is predictable monthly income instead of starting from zero every Monday.

Bottom Line

Commercial fleet contracts are one of the highest-leverage moves a pressure washing business can make. Less competition than residential, clients who pay on net-30 terms, and recurring revenue you can plan around.
