Pressure washing a semi-truck typically costs between $35 and $90 per wash, depending on whether you’re just getting a basic rinse or opting for full detailing. For most truckers, regular cleanings run about $50 to $75 per session, but full-service packages with interior detailing, engine degreasing, and waxing can push the cost up to $150 or more.
Keeping your truck clean isn’t just about looks — it’s about protecting your investment. Road grime, salt, and oil buildup can damage paint, corrode metal, and even reduce fuel efficiency. If you’re running a fleet or driving long haul, regular pressure washing helps maintain your rig’s resale value and keeps you DOT-compliant.

Key Takeaways
- Pressure washing a semi-truck usually costs between $35 and $90 per wash.
- Pressure washing is a quick and easy way to make your fleet shine. Depending on the service provider, this can take only a few hours or even minutes.
- You can include interior cleaning in your washing packages for a comprehensive wash-up of your fleet.
What Is Pressure Washing?
A pressure washer is a powerful device that uses large amounts of water, pressurized by an engine to scrub surfaces clean. You can use it for anything from removing mold on your house’s siding to getting rid of chewing gum off the ground.
The most common pressure washer used for cleaning consists of jets. This component is what creates a uniform water pressure used to clean. Hydro-jet cleaning is a more powerful and efficient pressure cleaning for removing dirt and stain build-up.
Should You Pressure Wash Your Semi-Truck?
Yes — pressure washing is one of the fastest and most effective ways to keep your semi-truck clean and road-ready. It removes caked-on dirt, oil, salt, and bugs that can corrode paint and damage components over time. Whether you’re an independent owner-operator or managing a fleet, regular pressure washing can help you maintain a professional image and extend the life of your vehicle.
For basic exterior cleaning, a standard pressure wash can take as little as 15 to 30 minutes. More detailed services, including engine degreasing, undercarriage rinsing, and sleeper cab cleaning, will take longer and cost more — but they’re well worth the investment if you’re hauling cross-country or working in harsh environments.
Pros and Cons of Pressure Washing a Semi-Truck
Manual cleaning can be tedious and time-consuming work. Here are the highlights of what pressure washing can offer.
However, pressure washing your fleet also has caveats that you should consider beforehand.
Pros
- Fast and efficient: A full exterior wash takes a fraction of the time compared to manual scrubbing. It’s ideal for large vehicles like semis, especially if you’re on a tight schedule.
- Cut down on labor: One technician with the right equipment can do the job of several people scrubbing by hand.
- Improves resale value: Keeping your rig clean helps prevent rust and paint damage, which protects long-term value.
- DOT compliance: A clean truck is less likely to raise red flags during inspections.
Cons
- Water usage: Pressure washers use a lot of water — up to 10 gallons per minute — which may be a concern in areas with usage restrictions.
- Chemical concerns: Some services use heavy-duty detergents or degreasers that may be non-biodegradable. Always ask what’s being used, especially if you haul food or sensitive cargo.
- Not ideal for interiors: Pressure washing isn’t suited for sleeper cabs or interiors with fabric, electronics, or delicate surfaces. Steam cleaning or manual detailing is better for those areas.
What Affects the Cost of Semi-Truck Pressure Washing?
The base cost to pressure wash a semi-truck usually covers just the exterior. If you’re seeing higher prices, here’s what’s likely driving the total up:
1. Interior Detailing
Adding sleeper cab or interior cleaning can raise the price by $50 to $100, depending on the condition and level of service. Expect higher rates if your cab has carpet, fabric upholstery, or heavy buildup. This process usually involves vacuuming, steam cleaning, and surface disinfecting — not pressure washing.
2. Mobile vs. Fixed Location Services
Mobile washing services come to you, saving time but typically costing more. A fixed-location truck wash might charge $35 to $70, while mobile detailers often start at $75 and up, especially for rural or remote locations.
3. Type of Service Package
Basic exterior washes are the cheapest option. But if you want extras — like engine bay degreasing, wheel brightening, undercarriage rinse, or wax treatment — those can bump your cost to $100 to $150 or more per truck.
4. Sleeper Cab Cleaning
Cleaning a sleeper cab adds time and complexity. Pros may charge $75 to $150, depending on whether they’re just wiping down surfaces or performing full upholstery and mattress cleaning. It can take anywhere from three to six hours if done thoroughly.
5. Reputation and Quality of the Service Provider
Well-known or specialty detailing companies often charge more — and that’s not always a bad thing. Look for reviews, before-and-after photos, and guarantees. Don’t overpay for basic service, but do expect to pay more for attention to detail and reliability.
6. Optional Treatments (Waxing or Sealants)
Think of wax like sunscreen for your paint job — it adds protection and shine. Some truckers skip it to save money, but if you’re driving in harsh conditions, it’s a smart add-on. Expect to pay $25 to $50 extra.
Is Pressure Washing a Semi-Truck Worth It?
Absolutely — keeping your semi-truck clean isn’t just about looks, it’s a smart form of preventive maintenance. A regular wash schedule helps protect your investment from corrosion, grease buildup, and road grime that can damage components over time. It also keeps you in good standing with DOT regulations and presents a professional image to customers and inspectors alike.
For most owner-operators and fleet managers, pressure washing every two to four weeks is a worthwhile habit. It’s an affordable way to extend the life of your truck and avoid more costly repairs down the road.
Think of it like changing your oil — routine, essential, and a lot cheaper than neglect.
