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. Aluminum brightening & polishing 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.
Trailer skirts, rails and polished fuel tanks running the Gulf Coast oxidise on a predictable cycle. Brightening is maintenance rather than a one-time fix, and regular washing extends the interval considerably.
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.
Served off I-10 and SH 36, in Austin County.
Typical work
- Aluminum tanker barrels and crude trailers
- Trailer skirts, rails, cross-members and rear frames
- Polished fuel tanks, steps and toolboxes
- Aluminum and chrome wheels
- Bumpers, visors, air cleaners and stacks
- Dump bodies and grain trailers
The process
Assess the alloy and the finish
Mill-finish, polished and coated aluminum respond differently, and anodised aluminum must not be acid-brightened at all. Getting this wrong is permanent, so it is settled before anything is applied.
Brighten
A controlled acid application dissolves the oxide layer. Dwell time is short and monitored — an acid left too long etches the surface it was meant to restore, which is the most common way this service is done badly.
Neutralise and rinse
The acid is neutralised and thoroughly rinsed. Residual acid keeps working after the crew leaves and will bloom back through the finish within weeks.
Polish
Mechanical polishing in progressive stages where a mirror finish is wanted. This is labour, and it is priced accordingly — a full trailer polish is a substantially bigger job than brightening the same trailer.
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.
