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.

Concrete and asphalt are not the same surface, and most lots are both

This is the part of lot washing that almost nobody puts in writing, and it is the one that does real damage. Asphalt is aggregate held together by bitumen, and bitumen is a petroleum product. The hot water and the degreaser that lift oil off a concrete lane attack that binder as well, because chemically they are being asked to dissolve the same family of thing. Run one setting across a lot that changes surface halfway down a row and the concrete comes out clean while the asphalt comes out eroded.

Almost every Austin dealership or yard is a mix. A concrete service apron, asphalt rows, a concrete dumpster pad, a paver customer entry, and gravel out back where the overflow inventory sits. That is why a single price per square foot for a lot is wrong before anyone arrives — and it is why the transition points are where damage happens, because a crew running one setting end to end is correct on part of the property and wrong on the rest. A useful question for any bidder: which surfaces on this lot are you treating differently, and how? A proposal that never mentions asphalt has quoted a concrete lot and will meet yours on the night.

Austin heat is the second variable, and it works against you. Dark pavement in July runs far hotter than the air above it, and a degreaser that flash-dries on contact has not dwelled — it has evaporated, leaving a residue that still has to be rinsed off. Nothing was cleaned and the chemical was still bought. Summer lot work is therefore pre-wet, cut into smaller sections and started earlier. That is the second reason this work runs overnight or at first light, and it has nothing to do with your customers.

A fleet yard and a dealership lot are not the same job

They get quoted as though they were, because from the street both are pavement with vehicles parked on it. Almost everything that decides the work is different.

If the yard already has a separator, use it. A site built with an oil-water separator serving a wash pad has the expensive part of the problem solved: the cheapest and cleanest plan is usually to wash toward the equipment that exists for exactly this, and the conversation turns into scheduling and scope rather than containment. One caution worth raising before the first visit, because it is the version that goes wrong: a separator has a capacity and a service interval, and a restoration wash pushing two years of accumulated product into a unit that is already due for pump-out has passed the problem along rather than solved it. Ask when it was last serviced, and sequence the big wash after that rather than before.

The fuel island is its own line item. On a fleet yard it is the dirtiest concrete on the property by a wide margin, it is the one surface where the spill is fuel rather than drip oil, and it is under a canopy that keeps rain off it — so nothing there has ever been diluted by weather. Quoting it inside a per-acre yard number buries the hardest twenty minutes of the visit.

The wash comes before sealing and striping, and after the patching

A lot wash is frequently not a cleaning purchase at all. It is a preparation step inside somebody else’s pavement project, and buying it in the wrong order is one of the more expensive mistakes available on a property budget.

Coatings do not bond through oil. Sealcoat applied over an unwashed lot releases first at the oil patches, which are the drive lanes and the spaces nearest the door — the most visible pavement you own. The failure looks like bad sealer and is almost always bad preparation. The same is true of striping paint: a stripe laid over a film is a stripe with a short life, and re-striping is not cheap enough to do twice.

• The order that works: repair, then wash, then seal, then stripe. Crack filling and patching come first because they generate debris and tracking of their own. Give new patch and crack material the cure time its manufacturer asks for before it takes heat and chemistry, then wash, then coat, then mark.
• If the lot is being sealcoated this year, the wash belongs to that job. It is the prep line on the paving contractor’s scope, not a separate purchase from a cleaning vendor. Properties routinely pay for it twice because the two contracts were signed by different people in different months.
• If you are only re-striping, wash first anyway. Layout gets marked against surfaces you can actually see, and paint needs the surface clean and dry rather than merely dry.
• Book the pavement walk for the morning after the wash. This is the one day a year the surface is genuinely visible: cracking, spalling, ponding low spots, failed joints and faded markings are all readable at once. Most properties assess pavement in whatever condition they find it, which means assessing the dirt.

To restate the boundary plainly, because this section could read as a sales pitch for work we do not do: Bailey & Bear does not seal, stripe, patch or resurface. We wash, we photograph what the wash uncovered, and we tell you what showed up so you can put it in front of a paving contractor. That report is worth more than the photographs of clean concrete.
