Dealership & fleet lot pressure washing in Austin

Oil is two different problems, and only one of them washes off

On a lot, the soil that decides whether the job looks finished is petroleum — and it arrives in two forms that behave nothing alike.

Fresh surface oil. Drips under parked inventory, the film across a drive lane, tire-rubber transfer at the turn. It sits on top of the concrete and lifts with heat, a degreaser and dwell time. Cold water does not lift it; it spreads it outward into a wider gray halo and pushes it into the pores, which is why a lot washed with cold water can look worse a week later than it did before anyone touched it.

Oil that has soaked in. The black patches under spaces that have held cars for years. That petroleum has migrated into porous concrete and now sits below the surface. Degreasing pulls out what is near the top; what is deeper wicks back up over the following weeks and the patch ghosts. It usually improves substantially, usually does not vanish, and getting there can take repeat treatments. Anyone promising to remove it from a photograph has not looked at it — we mark which patches we expect to clear and which to lighten at the walkthrough, before anything is signed.

The first visit is a restoration visit

This is the part most recurring proposals get wrong, and it is worth understanding before comparing bids.

A lot that has never been washed, or was last washed two years ago, is carrying soil that has had time to set. Removing it takes pre-treatment, dwell time and in places a second pass. The visits after it are removing weeks of soil rather than years, and are genuinely faster. A proposal pricing them identically has guessed wrong on one — either the first visit is underbid and gets rushed, or every visit afterwards carries a price it does not need. We quote them separately.

That is also the real argument for a cadence, and it is not that the property looks nicer. Soil removed before it sets never becomes a restoration job. Once oil has cured into the concrete, no cadence undoes it.

Where the water goes is the constraint on a lot

Every wash makes run-off, and on a dealership or fleet yard that run-off is carrying oil, brake dust, degreaser and whatever else has dripped onto the pavement. Rain is allowed to enter a storm drain. Water like that is not rain, and a storm system discharges to a creek rather than to a treatment plant.

So the drain is planned before the machine starts: inlets in the wash area are blocked and the water contained and recovered, or the wash routed to a landscaped area that can absorb it. Anything carrying heavy petroleum is a recovery job, not a rinse. There is also a step before any water at all — standing oil and fresh spills are swept up dry first, because washing a spill only moves petroleum into the drainage system faster. The obligation follows the property owner rather than the contractor, which is a good reason to ask a bidder how they handle it before they are on site. Commercial pressure washing in Austin has the full treatment.

A full lot is a scheduling problem, not a washing problem

You cannot wash the concrete under a car, and on a dealership lot that is most of the surface. So the practical question is never “can you wash the lot” — it is how much of it can actually be exposed on the night the crew is there. There are three honest answers, and the scope should say which one it is buying.

• Sectioned against a move plan. The lot is split into blocks; your team clears block A before the crew arrives and moves inventory into it once it is washed. This is the only version where the whole lot ends up clean, and it needs someone on your side awake.
• Lanes and fronts only. Drive lanes, the customer approach, the showroom front, sidewalks and the service drive — the surfaces people walk and drive on. Rows under inventory stay as they are. A legitimate scope, and what most recurring plans actually are, but it should be written down so nobody expects the rows.
• Rolling coverage. A different section each visit, so the whole lot gets covered across a cycle rather than in one night.

Service drives and the ground around the wash bay and dumpster are usually the worst surfaces on the property and the ones customers see least, which is exactly why they are the first thing cut from a low bid.

What we wash, and what is quoted separately

On the property: drive lanes and customer approaches, inventory rows where they can be exposed, sidewalks, the showroom or building front, service-drive concrete, dumpster and wash-bay pads, and hardscape entries.

• Vehicle exteriors are not a hardscape job. Paint, trim, seals and glass do not take the pressure a concrete lot takes, so vehicle work is a different method on different equipment and is priced on its own — never folded into a per-lot number.
• Facades and signage are usually soft washed, not pressure washed. Stucco, EIFS, painted metal and composite panel all fail under the pressure concrete wants. Soft washing covers what that method is and which surfaces need it.
• No sealing, striping or resurfacing. Washing reveals cracking, spalling and faded striping. It does not repair them.
• No hoods, ducts or exhaust systems — certified NFPA 96 work, referred to certified partners.
• No published per-square-foot rate. Lots are quoted in writing after a walkthrough, because condition and access move the number more than area does.
