Municipal Fleet Undercarriage Wash Systems
Drive-over salt neutralization for plow trucks, salt spreaders, and utility vehicles — full chassis washed in under five minutes per vehicle, no capital project required.
Municipal fleets fight winter on both sides: plow trucks and salt spreaders lay down the de-icing chemicals, then drive through them for months. Road salt creeps into frame rails, brake lines, and fuel lines where an exterior wash never reaches. A drive-over undercarriage washer built for municipal yards washes and salt-neutralizes the full chassis in under five minutes per vehicle — the driver never gets out, no one works underneath, and the pads drop into the wash lane you already have.
Built for Public-Works Yards
Plow Trucks & Salt Spreaders
The irony of winter operations: the vehicles spreading the salt take the worst of it. End-of-shift drive-over passes keep them in service all season.
Dump Trucks & Utility Vehicles
Hauling, patching, and storm response run through brine for months. One lane sized to the largest unit covers the whole yard.
Multi-Site Municipal Fleets
The Fleet Preservation Program follows the same disciplined process whether it's one wash bay or a multi-site municipal fleet — assessment, design, neutralization, training, annual review.
Why Municipal Fleets Go Drive-Over
Under 5 Minutes Per Vehicle
The driver rolls across at walking speed at end of shift without getting out — no dedicated wash crew, no overtime, no vehicle downtime beyond the pass itself.
Neutralizes, Not Just Rinses
A second spray bar applies D-Salt neutralizing chemistry that reacts with chlorides hiding in seams and crevices. Rinsing alone leaves the chloride that keeps corroding after the vehicle dries.
No Pit, No Concrete Work
Drive-over pads sit in the existing wash lane and plumb to the pressure washer you already own — 4 GPM at 2,000 PSI minimum. Public-works budgets don't need a capital project to start.
The system is The Neutralizer™, Enzo's original drive-over unit — dual spray bars, 4-chemical selector manifold, and D-Salt neutralizing chemistry. Also see the commercial truck fleet systems and the full fleet corrosion prevention program.
Municipal Fleet Wash Questions
What are the best undercarriage wash systems for municipal fleets?
For municipal fleets, the best system is a drive-over unit that neutralizes salt rather than just rinsing it — plow trucks and salt spreaders need chloride chemistry (D-Salt) applied to the full chassis, not a surface wash. The system should be sized to the largest vehicle in the yard, run off the pressure washer the facility already owns, and fit end-of-shift routines at under five minutes per vehicle with no operator underneath.
How do municipalities justify an undercarriage wash system in the budget?
With avoided repair cost. A single corroded fuel or brake line repair runs $2,000+, and plow trucks are the highest-exposure vehicles in any fleet. One avoided repair covers a large share of the system — and the Annual Fleet Health Review documents the prevented cost year over year for budget reporting.
Can one system serve plow trucks, dump trucks, and utility vehicles together?
Yes, as long as each vehicle fits the lane. The system is sized once to the largest vehicle — plow trucks, salt spreaders, dump trucks, and utility vehicles all run through the same lane without adjustment.
Does it work with our existing pressure washer and wash lane?
Yes. The drive-over pads are positioned in the existing wash lane and plumbed to your current pressure washer — 4 GPM at 2,000 PSI minimum — with no excavation or concrete work. For municipalities planning a full facility, it also integrates into Enzo's custom wash bay designs.
Who handles installation and training for a municipal fleet?
Enzo's does — from equipment selection through layout and installation — plus operator training on wash frequency and technique, and preventive maintenance to keep the system running through the season it matters most.
