The right livestock trailer wash rig is a hot water pressure washer with high flow for flushing (8 to 20 GPM), 3,000 PSI or more, a tank big enough to wash between fill-ups, and dual guns if two people wash at once. For winter washouts, choose an enclosed trailer with a cold weather package so the pump and plumbing don't freeze.
Below are six Hot And Mighty builds that fit livestock trailer washouts, from a skid you slide onto your own truck to a 20 GPM, four-gun rig for a truck wash. Prices are listed starting prices on hotandmightydirect.com as of November 2026; final pricing is in your written quote.
Why does livestock trailer washing need hot water and high flow?
Hot water loosens manure, bedding and fat faster than cold, and a trailer dries sooner after a hot rinse. Kärcher's cattle trailer guide recommends a hot water pressure washer at 60 to 80 °C (140 to 176 °F) and says the trailer must be completely dry before disinfection (Kärcher).
Washing works. In an Iowa State study of swine transport trailers, power washing with disinfectant cut viral contamination by more than 99% and fully inactivated PEDv, while scraping and baking alone did not (SwineWeb).

Which build fits your operation?
One hauler washing their own trailers
The Slider MDS-5357 slides onto a trailer or flatbed you already own and runs 5 GPM hot water off a diesel engine. If you want more flush power for the floor and gates, the Money Maker 3010V puts out 10 GPM.
A farm or feedyard with a washout area
The Open TA5 MDS-8307K carries 900 gallons, so you can wash more trailers between fill-ups, and runs two guns off one 8 GPM diesel washer.
Winter washouts in the Midwest and Plains
The General TA5 MCS-3008 CWP is an insulated, propane-heated enclosed trailer with two 400 gallon tanks, an outside fill line and outside hose access doors. Our cold weather packages keep the washer and plumbing above freezing between jobs.
A truck wash or integrator washing many trailers a day
The Open TA3 MDS-10307 runs two 10 GPM diesel-fired hot water washers with four hose reels and 800 feet of hose, so up to four people can wash at once.
What options matter for livestock trailers?
Ask about these when you request a quote:
- A 2-step detergent package: presoak, then soap, then rinse, switched by remote at the gun, so one operator never walks back to the rig.
- Longer hose and extra reels to reach both decks and the nose of a pot trailer.
- Larger tanks or a fill line if you wash away from a hydrant.
- Diesel engines and diesel-fired burners if your site already runs on diesel.
Livestock trailer wash water carries manure, so plan where it goes. Handle it under your state and local rules through your facility's approved collection or disposal.
Frequently asked questions
What size pressure washer do I need to wash a livestock trailer?
Most livestock trailer washouts are done with 5 to 10 GPM per gun at 3,000 to 3,500 PSI. Higher flow flushes manure and bedding faster; a truck wash running several trailers a day often wants 10 GPM per gun or more.
Should I use hot or cold water to wash livestock trailers?
Hot water. It loosens manure and fat faster and helps the trailer dry sooner, which matters because disinfectant works best on a clean, dry surface. Kärcher recommends 60 to 80 °C (140 to 176 °F) for cattle trailers.
Does power washing kill PEDv in swine trailers?
Washing plus disinfectant did in an Iowa State study: power washing with disinfectant reduced viral contamination by more than 99% and fully inactivated PEDv in transport trailers. Follow your veterinarian's and integrator's protocol for disinfectant and drying.
Can I wash livestock trailers in winter?
Yes, with an enclosed, heated rig. Our cold weather package adds insulation and propane heat so the washer, tanks and hoses don't freeze between washouts.
How much does a livestock trailer wash rig cost?
Listed starting prices on hotandmightydirect.com run from $29,530 for the Slider MDS-5357 skid to $72,490 for the 20 GPM Open TA3 MDS-10307, as of November 2026. Your written quote covers your options and the build time.
