Sealy sits on Interstate 10 in Austin County, at the western edge of A1 Mobil's standard coverage, where the Houston metro gives way to farmland. It is a genuine crossroads town — the interstate meets SH 36 here — and the fleet mix is agricultural and trucking rather than urban service. Fleet & truck wash here is booked on site — the crew arrives with the water, the pressure, the power and the containment, and the work happens in your yard.
Farm trucks and haul units accumulate a mix of field soil, fertiliser residue and road film, and the fertiliser component is precisely what surface water regulation exists to keep out of a ditch.
The Sealy market
Austin County agriculture runs cattle and row crops, which means tractors, implements, livestock trailers and grain trailers — equipment carrying organic residue and heavy soil that needs hot water and dwell time rather than pressure. Livestock trailers in particular need odour treatment as part of the washout, not just a rinse.

What gets washed
A typical fleet route covers a mix of the following in one visit:
- Sleeper and day-cab tractors, including polished aluminum and stainless trim
- Dry vans, reefers, flatbeds and tankers
- Box trucks, straight trucks and stake beds
- Cargo vans, sprinters and service vans
- Dump trucks, mixers and roll-offs
- Pickups and crew trucks running with the fleet
How a fleet visit runs
Walk the yard and seal the drains
Before any water moves, the crew locates every storm inlet in the work area and closes it with drain seals and booms. This is the step most wash vendors skip, and it is the step that decides whether the visit creates a liability for you.
Pre-soak and chemical dwell
Units get a low-pressure detergent application matched to what is actually on them — road film, diesel soot, brake dust or agricultural residue. Dwell time does the work so pressure does not have to, which is what protects decals and paint.
Two-step wash and rinse
An acidic brightener followed by an alkaline soap lifts oxidation off aluminum and film off painted surfaces. Hand detail on grilles, bumpers, fuel tanks and wheels where a pressure wand alone leaves shadows.
Recover, transfer and document
The vacuum system pulls the water back, it transfers into the 500-gallon onboard tank, and the crew logs each unit. On contract accounts that log becomes a per-unit condition report.
Where the wash water goes in Sealy
Rural drainage goes to ditches, creeks and ultimately the Brazos system with no intermediate treatment whatsoever, which makes agricultural wash water a direct surface water question. Manure and nutrient load off livestock trailers, plus fuel and hydraulic oil off equipment, are exactly what that regulation addresses. The same containment and recovery process runs here as anywhere else — the water leaves with the crew.
Containment is not a line item on the quote — it is how every job runs. Drain seals and booms close the inlets before any water moves, a vacuum system recovers the water from up to 200 feet out, and it transfers into a 500-gallon tank on the wash vehicle that leaves with the crew.
