Parking lots are among the hardest surfaces a cleaning professional will ever face, and a machine that copes with a driveway will often struggle on a commercial lot. A pressure washer for parking lot work must handle oil, rubber, fuel spills, gum, and large areas of concrete, often under time pressure and with vehicles still moving around it. It is a demanding job that rewards the right equipment, a sensible method, and a clear understanding of the soil you are dealing with. This guide explains what separates a machine that can clean a car park quickly and profitably from one that leaves streaks, misses the oil, and burns a whole day doing it. Read it as a practical buying and working guide, because on commercial ground the difference between the right machine and the wrong one is measured in hours and in the quality of the finished surface the client can see.
Why Parking Lots Are a Different Cleaning Job
A car park looks like a simple slab of concrete, but the mix of soil on it, and the way it must be cleaned, make it a job apart from ordinary pressure washing.
The soil is heavy and varied. A busy parking lot collects a remarkable range of contamination, and each type behaves differently under the jet. Engine oil and transmission fluid drip from parked cars and soak deep into the concrete, where they darken the surface and resist plain water. Tyre rubber lays down black marks at every braking point and turn. Fuel and coolant leave their own stains, gum builds up in walkways, and of course mud, litter, and the general grime of traffic add a layer over it all. Because concrete is porous, liquids sink in rather than sitting on top, so cleaning means lifting contamination out of the surface rather than simply rinsing it off. This is the first reason a parking lot is a specialist job: the stain that matters is often below the surface, not on it, and a machine must have enough force and volume to reach it.
The scale demands speed and stamina. The second difference is sheer size. A commercial car park may run to thousands of square metres, which turns cleaning from a task into a project. A single wand moving at walking pace would take days, so professionals rely on surface cleaners that cover wide strips, machines with high flow, and equipment that can run for hours without faltering. Stamina matters as much as power, because the job is a test of duty cycle and fuel or water capacity as much as of pressure. Speed is also commercially essential, because the cleaning must fit around opening hours and the needs of the business. Together, the heavy soil and the large area explain why a dedicated commercial setup, often trailer mounted pressure cleaners or similar, is the normal tool for parking lot cleaning rather than a homeowner machine pressed into service. Understanding this scale is the first step to buying well.
What a Pressure Washer for Parking Lot Work Must Deliver
Once the nature of the job is clear, the specification a machine needs to meet becomes far easier to define.
Enough pressure to lift, and enough flow to clear. Parking lot cleaning needs both halves of the pressure washer equation working hard. Pressure in the region of 3500 psi is a sensible working level, because it loosens compacted dirt and rubber without the extremes that damage concrete or demand unreasonable skill. Flow is at least as important, since it is sheer volume of water that flushes the loosened soil away and covers large areas at a reasonable pace. A machine flowing five gallons per minute or more, such as a commercial unit built around a robust pump, will clean far faster than a lower flow machine of the same pressure. A good pressure washer 5.5 gpm unit sits at the top of the practical range for this work and gives a professional real speed on big slabs. The combination of strong pressure and generous flow is what gives a professional the speed the job demands, and it is the single most important characteristic of a genuine pressure washer for parking lot applications.
Duty cycle, build, and serviceability. A car park job can run for hours, so the machine must be built to keep going. That means an engine and pump rated for continuous commercial use, cooling that copes with long sessions, and a frame sturdy enough to survive being loaded, moved, and worked hard season after season. Serviceability matters just as much, because a machine that cannot be repaired economically is a liability in a business. Choose equipment with easily sourced pumps, seals, and nozzles, and treat maintenance as part of the operating routine rather than an occasional afterthought. Reliability is not a luxury on commercial work, it is the difference between finishing the job and letting a client down. A professional parking lot cleaning setup is therefore judged on endurance and easy servicing as much as on raw pressure, because a machine that breaks mid project costs far more than it saved at purchase. Buy endurance, and the rest follows.
The Power and Flow You Actually Need
Buying for parking lots means matching the machine to the real demands of the work rather than to a single headline figure.
Reading the numbers for commercial concrete. Pressure, flow, and the difference between them decide how quickly a car park comes clean. Around 3500 psi is the practical working range for commercial concrete, strong enough to reach deep grime yet manageable with a surface cleaner. Flow should ideally be in the region of four to five and a half gallons per minute, because the volume of water is what carries soil off the slab and keeps the surface cleaner working efficiently. A machine specified as a pressure washer 5.5 gpm sits at the top of that range and will comfortably run a wide surface cleaner across a big lot without slowing down. Multiply pressure by flow and you get cleaning units, a fair way to compare machines, since a pressure washer for parking lot use with high flow will outwork one that advertises the same pressure but delivers a thin stream. Read the specification as a whole, and remember that on a large lot, flow usually makes the bigger difference to how many hours the job takes.
Why a light machine cannot keep up. It is tempting to start with a homeowner unit and upgrade later, but on parking lots that usually proves a false economy. A light machine lacks both the flow and the duty cycle for large commercial areas, so it cleans slowly and overheats or tires long before the work is done. It also lacks the build to survive being used commercially, and it will need replacing within a season or two under that workload. The result is a string of unhappy clients, unfinished schedules, and a machine that has to be nursed rather than used. Stepping up to a proper commercial pressure washer, or better a trailer mounted unit with adequate water and fuel, is not a luxury on this work, it is the minimum for doing the job profitably and maintaining a reputation that keeps the contracts coming. Buy once, buy right, and let the machine earn its cost back many times over.
Hot Water and the Oil Problem
Of all the soil a parking lot presents, oil is the stubbornest, and heat is the tool that turns an impossible job into a routine one.
Why heat changes everything on oil. Cold water and pressure will move surface oil around, but it rarely removes the deep, baked contamination that darkens the concrete and draws complaints from clients. Heat changes the chemistry of the problem by lowering the viscosity of oil and grease so they release from the surface and can be lifted and rinsed away. A hot water machine, or a diesel pressure washer with a burner, makes short work of petrol and diesel stains, cooking oil, and the general oily film that accumulates wherever vehicles park. On commercial work, the difference in both speed and final quality is dramatic, and it is often the single upgrade that turns a struggling cleaning operation into a genuinely professional one. For serious parking lot cleaning, heat is not a refinement, it is frequently the deciding factor between a clean lot and a stained one. If oil appears anywhere in your regular work, treat heat as a priority.
Choosing between cold and hot machines. A cold machine has its place, and for lots that are mainly dirty rather than oily it can be entirely adequate and cheaper to run. A hot water unit costs more to buy and to operate, because it burns fuel to heat the water, but it removes oil far more effectively and often needs less detergent, which partly offsets the running cost. The diesel engine hot water pressure washer is a common professional choice because it combines endurance with heat, making it capable of long sessions on heavily soiled sites. When deciding, look honestly at the work you will do most often. If oil and grease dominate, invest in heat from the start, because no amount of pressure will fully solve an oil problem that only temperature can undo, and clients judge the result on the pavement they can see. Buying cold when you needed hot is the costliest mistake on this work.
Surface Cleaners and Even Coverage
No one cleans a large car park well with a wand alone, and the right attachment is central to professional results.
Why the surface cleaner is essential. A surface cleaner is a wide, spinning attachment that covers a broad strip of ground in a single pass, keeping the nozzles at a constant height and distance so the cleaning is even and the risk of leaving stripes is greatly reduced. On parking lots, where speed and consistency matter, it is the difference between a professional finish and a patchy one. The large area a surface cleaner covers means the machine gets through the work in a fraction of the time a wand would take, and the even pressure across the cleaning head reduces the chance of damaging the concrete. A good surface cleaner, matched to the flow of the machine, is not an accessory so much as a requirement for any serious pressure washer for parking lot application, and operators who neglect it soon find themselves working twice as hard for a worse result. Choose one sized to your machine’s flow and you will never look back.
Wands, nozzles, and the edges. Even with a good surface cleaner, a wand remains essential for the details a rotating head cannot reach. Kerbs, painted lines, drains, corners, and the edges around islands and columns all need the wand, and a set of nozzles lets you match the spray to each surface, from a broad fan for rinsing to a more focused tip for stubborn patches. A telescoping extension wand for pressure washer work lets you reach without straining, and quality couplers keep every changeover quick and dry. The trick is to use the surface cleaner for the bulk of the open slab and the wand for the perimeter and the fine work, blending the two so the job looks uniform. Handled this way, the machine covers ground quickly while still delivering the finish a paying client expects, and the work feels organised rather than frantic from start to finish. With the right attachments and a little practice, a big slab stops feeling daunting and starts to feel like routine work you can bill for with confidence, and the quality stays consistent from the first hour to the last.
Water Supply and Recovery on Site
On a commercial lot, access to water and the handling of runoff can be as important as the cleaning machine itself.
Feeding a high flow machine on site. A machine flowing several gallons a minute drinks a great deal of water, and a parking lot rarely has a convenient tap where you need one. Feeding such a machine from a domestic supply is often impossible, which is why professional setups usually carry a buffer tank or rely on a trailer with its own reservoir. This is one reason trailer mounted pressure cleaners and power wash trailers for sale are popular for commercial work, because they arrive self sufficient with water, fuel, and equipment on board. Planning the water supply before the job prevents the frustration of running dry halfway through an important clean. A steady, adequate feed is the foundation of fast, consistent work, and on a parking lot it deserves as much thought as the machine itself. Sort out water first, and the rest of the job falls into place far more easily.
Managing runoff and protecting drains. Cleaning a large paved area produces a correspondingly large volume of dirty water, and how that water is handled matters. Runoff carries oil, detergent, and suspended dirt, and letting it flow unchecked into storm drains is both irresponsible and, in many places, illegal. Professional parking lot cleaning therefore includes some form of containment or recovery, whether by bunding the work area, blocking drains, or using a system that captures and separates the wastewater. Recovering water also allows detergent and contamination to be disposed of properly rather than spread across the site. Planning recovery is part of doing the job well, and it protects both the environment and the operator from the consequences of careless discharge. It is a responsibility no serious cleaning business can ignore, and it is increasingly the mark of a professional operation that wins the best contracts. It also shows the client that their site is being handled by people who understand the rules, which builds trust far beyond a single clean and makes repeat bookings far more likely.
Trailers and Mobile Setups
For regular parking lot work, how you carry and support the equipment becomes as important as the equipment itself.
The case for a trailer. A trailer turns a pressure washer into a complete mobile cleaning station, carrying the machine, the water tank, the fuel, the hose reels, and the tools, so the whole setup arrives ready to work. This self sufficiency is exactly what commercial sites need, where power and water are scarce and the job is large. A trailer also saves time and labour on every job, because everything has a place and nothing has to be carried piece by piece, and it keeps the gear secure and organised between contracts. A pressure washer trailer also keeps the heavy load off the day to day vehicle and lets a small operator look and work like an established business. For anyone who intends to clean parking lots regularly rather than occasionally, a trailer based setup is the practical, professional foundation. It pays for itself in saved time across the first few big jobs alone.
Choosing a mobile setup and keeping it working. A trailer setup should be matched to the work, with a tank big enough to avoid constant refilling, a machine rated for continuous duty, and secure mounting for the pump, the burner if fitted, and the water supply. Good pressure washer hose reels keep the working area tidy and the hose protected, and storage for nozzles, couplers, and detergent keeps everything to hand. Purchasing a ready made commercial trailer, or building one around a proven machine, is a decision that shapes how much work can be done in a day. It is also worth keeping the trailer well maintained, since everything the business relies on rides on it. A well chosen and well kept trailer setup turns a good machine into a genuine business asset that can take on the biggest residential and commercial contracts with confidence, and it grows with the business as the workload increases. Looked at as a whole package, a trailer is the single change that lifts a cleaning operation from occasional jobs to a genuine commercial service, and it pays for itself as soon as the contract work starts to build.
Scheduling and Working Around Traffic
A parking lot is a working space, and the way the cleaning is scheduled and organised often decides whether the job succeeds.
Working when the lot is empty. The best parking lot cleaning is done when the lot is empty, which usually means before opening, after closing, or overnight. Working around parked cars wastes time, leaves missed patches, and risks damage to vehicles from overspray or moving hoses. Planning the clean for a quiet window lets the surface cleaner move freely, keeps the machine working efficiently, and produces a uniform result. It also removes the safety risks that come with cleaning around moving traffic and pedestrians, which is a real concern on a live site. Agreeing the schedule with the client in advance, and confirming access, lighting, and any permits, avoids last minute problems. A well planned window of quiet time is often worth more than extra pressure, because a clean run lets the machine do its best work without interruption, and it keeps both the operator and the public safe throughout the session.
Working the site in a logical order. Even within a cleaning window, a sensible method saves time and improves the finish. The usual approach is to work the open areas with the surface cleaner first, in overlapping strips, then return with the wand for edges, kerbs, drains, and stained spots, and finally rinse the whole area so no detergent or dirty water is left behind. Pre treating heavy oil spots before the main pass makes them far easier to remove when the machine reaches them. Working from the far end toward the exit lets the operator leave the site without crossing freshly cleaned ground, and it keeps the equipment moving efficiently. This orderly method, combined with the right machine and the right tools, is what turns a large car park from an intimidating task into a routine, repeatable job that a professional team can deliver on schedule and to a standard the client will notice and remember. A clear plan, agreed in advance and followed without fuss, is what separates a professional contractor from an amateur, and it is often what wins the contract again the following year.
Safety and Compliance
Commercial cleaning brings responsibilities, and a professional approach to safety and compliance protects people, property, and the business itself.
Keeping people and property safe. High pressure water and hot machines pose real hazards on a public site, so safety planning is part of the job. Keep pedestrians and vehicles clear of the work area, use barriers and signs where necessary, and never allow anyone within range of the jet or of runoff. Treat a hot water machine with extra respect, since scalding water and hot surfaces add risk, and keep fuel handling careful and well away from ignition sources. Inspect hoses, fittings, and the machine before each session, because a burst hose at pressure is dangerous and disruptive. On a parking lot, the layout itself brings hazards from traffic, so coordination with the client and clear marking of the work zone are essential. Good safety habits protect everyone involved and protect the reputation of the business, which is hard won and easily lost on a single careless day. Treat every site as if an inspector and a customer are watching, because on commercial ground they often are, and the habits you build will protect the business for years to come.
Meeting the rules that apply. Parking lot cleaning is often subject to local rules about wastewater, detergents, and disposal, and a professional operation must know and follow them. Storm drain protection, containment of runoff, and correct disposal of collected wastewater are frequently required, and ignoring them can bring fines and serious damage to a firm’s standing. Detergent choice also matters, since some products are restricted and many require careful handling and dilution. Keeping records of what was used and how waste was managed shows good practice and protects the business if questions arise. Staying compliant is not just about avoiding penalties, it is part of being a business that clients and regulators can trust. A clean car park, delivered responsibly, is worth more than one that is merely clean on the surface, and it is the kind of work that builds a lasting professional reputation. Clients return to cleaners they trust, and a record of responsible, compliant work is worth more than any advertisement when the next contract is being decided.
Detergents and Environmental Care
The right chemical, used well, makes parking lot cleaning faster and more thorough, while careless use creates problems.
Using detergent to lift oil and grime. Pressure and heat do most of the work, but the right detergent unlocks soil that water alone struggles to move. A good degreaser breaks the bond between oil and concrete so it can be lifted and rinsed away, and a pre soak on heavy staining gives the chemical time to work before the machine arrives. Application should be even and controlled, with proper dwell time and the correct dilution, rather than a random spray that wastes product and leaves streaks. Matching the detergent to the soil, an alkaline degreaser for grease and a suitable cleaner for general grime, delivers better results with less effort. Used properly, detergent is a force multiplier on commercial work, reducing the number of passes and the amount of fuel burned, while improving the finished result that the client actually sees. A little chemistry, applied wisely, saves hours of labour across a large lot. The aim is always to let the chemistry do the hard lifting so the machine only has to rinse the loosened soil away, which protects the concrete and speeds the whole job.
Choosing products that respect the site. As important as cleaning power is what happens to the chemical afterwards. Where runoff can reach drains, planting, or watercourses, the choice of a more environmentally responsible, readily degradable detergent is not only responsible but often required. Using the minimum effective dose, recovering runoff where possible, and avoiding products that are unnecessarily harsh all reduce environmental impact without sacrificing results. Sensible product choice also protects the operator, since gentler formulations are kinder to skin and lungs. The best operators treat environmental care as part of doing a professional job, not as a constraint on it, because a responsible cleaning process is one that can be repeated with confidence across every site. Care for the environment and a quality clean are not in conflict, and the best work achieves both, leaving the site clean and the surroundings unharmed. Done well, a parking lot clean can even improve the site’s appearance and safety, which is a selling point for the client and a reason to book the work again.
Profit and Pricing the Work
Parking lot cleaning is a business, and understanding the economics turns good work into a sustainable operation.
Why the right machine pays for itself. The speed a professional machine delivers is what makes the work profitable. A pressure washer for parking lot use with strong flow and heat finishes a lot in a fraction of the time a light machine would take, which means more jobs per week and a better return on every hour. The difference between a job that takes four hours and one that takes eight is entirely commercial, and it is why buying adequate equipment is an investment rather than an expense. Fuel, detergent, and wear parts are running costs that a fast, efficient machine reduces per square metre, while downtime for repairs is a direct loss of income. When the machine is matched to the work, the numbers stack up in a way that keeps the business healthy and the operator competitive on price without ever cutting corners on quality or safety. When the machine is right, every hour on site is productive, and the operator can take on more work without adding more equipment.
Pricing the job to reflect the work. Parking lot cleaning should be priced to cover the machine, the fuel, the water, the detergent, the disposal of wastewater, and the time, with a sensible margin on top. Because these jobs vary greatly in size and soil, pricing by area is often fairer than a flat fee, and heavy oil or gum justifies a higher rate than a simple wash of dusty concrete. It also pays to account for access, the need to work out of hours, and any containment or permits the site requires. Offering a maintenance contract, where the lot is cleaned on a regular schedule, smooths income and keeps equipment productive. Underpricing the work is a common mistake that leaves a thorough job looking unprofitable, so price for the quality that a proper commercial machine and method can deliver, and let the results win the repeat business. A fair price for a thorough job keeps clients loyal, and loyalty is worth far more than a single low bid that leaves the work unprofitable.
Choosing Your Machine
Bringing the requirements together makes the choice of machine for parking lot work far more straightforward.
Matching the machine to the lot. Start from the biggest and dirtiest lot you expect to clean regularly, and let that define the specification rather than the average job. A commercial pressure washer of around 3500 psi with high flow is the sensible working level, and if oil is common, add heat from the start. Decide whether you need a portable machine or a trailer based setup, and consider the water and fuel capacity the work demands. Ensure the pump, engine, and frame are rated for commercial duty, and that replacement parts are easy to source. Only then consider brands and prices, because a bargain that cannot do the job is no bargain at all. The table below summarises how the important features align with the demands of parking lot cleaning so the decision becomes a matter of matching, not guessing, and so you can compare machines on the things that truly matter to the work.
| Requirement | What To Look For | Why It Matters |
|---|---|---|
| Pressure | Around 3500 psi | Lifts compacted dirt and rubber |
| Flow | 4 to 5.5 gpm | Covers large areas quickly |
| Heat | Hot water or diesel burner | Removes oil and grease |
| Duty cycle | Continuous commercial rating | Survives long sessions |
| Setup | Portable or trailer mounted | Carries water, fuel, tools |
| Tools | Surface cleaner and wand set | Speed and even coverage |
Before you commit. Once the specification is settled, do a final check of the practical details before spending money. Confirm that the pressure and flow suit commercial concrete, and be honest about whether the work really calls for heat. Check the duty cycle and the build quality, and make sure the pump, seals, and nozzles can be replaced easily and locally. Plan the water supply and the handling of runoff before the first job, not during it. Consider whether a trailer mounted setup makes more sense than a portable machine for the sites you serve. Compare total cost of ownership, not just the sticker price, and choose a supplier who stands behind the equipment. Done this way, the purchase becomes a considered business decision, and the machine a dependable partner rather than a source of regret. Buy for the largest and dirtiest lot you expect, not the easiest one you can imagine, and the machine will still be earning its keep long after a cheaper unit has been replaced.
Frequently Asked Questions
What pressure washer do I need for a parking lot? For commercial concrete you generally want around 3500 psi with plenty of flow, ideally four to five and a half gallons per minute, and heat if oil is common. That combination gives the power to lift compacted dirt and the volume to clear it quickly across large areas. A machine advertised at, say, 5.5 gpm at that pressure is well suited to serious parking lot work, and it will outpace a lower flow machine of the same pressure by a wide margin. Flow is the number that decides how many square metres you can cover in an hour, so on large lots it is usually worth more than a small gain in pressure. Aim for a machine built around a durable commercial pump, with a frame and engine rated for continuous work, because a parking lot contract rewards endurance as much as raw cleaning power.
Can a cold water pressure washer clean a parking lot? It can clean a lot that is mainly dirty rather than oily, and it is cheaper to buy and run. However, cold water tends to move oil around rather than remove it, so heavily oiled concrete will still show staining after cleaning. If your regular lots have oil and grease, a hot water machine or a diesel burner is worth the extra cost, because it lifts the contamination that pressure alone cannot touch. Heat lowers the viscosity of oil and grease so they release from the concrete, and the improvement is obvious within minutes on a stained slab. If you cannot afford a hot machine at first, a diesel burner upgrade or a rented hot unit for the worst jobs is a sensible halfway step, but serious commercial work almost always ends up needing heat built in. In the long run, the productivity and the quality that heat brings make it the cheaper choice.
Do I need a surface cleaner for parking lot cleaning? Yes, a surface cleaner is almost essential on commercial lots. It covers wide strips evenly and quickly, which is the only realistic way to clean a large area consistently, and it greatly reduces the striping and surface damage a wand can cause. Use the surface cleaner for the open slab and keep a wand for kerbs, drains, edges, and stubborn spots, blending the two for a uniform finish. A surface cleaner keeps the nozzles at a constant height, which prevents the striping and streaking that a hand wand often leaves, and it lets the machine move at a steady pace around the whole lot. Match the cleaner to your flow so the head spins correctly, and the difference in both speed and appearance will be immediate. Done this way, the lot comes out uniform and streak free, which is what the client will judge and remember.
How do I remove oil stains from a parking lot? Pre treat the stain with a suitable degreaser, give it time to dwell, then clean with hot water and adequate flow so the oil is lifted and rinsed away. Deep or old stains may need a second treatment, and on the worst spots a little patience pays off. Heat is the most effective single tool against oil, because it releases the contamination from the concrete so water and detergent can carry it clear of the surface. Apply the degreaser evenly, let it dwell as the label directs, and keep the water hot for the rinse, because cold water will only spread the residue. For severe staining, work in small sections and treat twice rather than blasting harder, which risks etching the concrete. Patience and heat remove oil far better than brute force ever will. Applied properly, this approach leaves the concrete clean without the surface damage that careless high pressure can cause.
Is a trailer mounted machine better for parking lots? For regular commercial work, a trailer mounted setup is usually the better choice. It carries the machine, water, fuel, and tools as one self sufficient unit, which suits large sites where services are scarce. It also saves time on every job and keeps the equipment organised and secure. A portable machine can work for occasional small lots, but a trailer generally proves faster and more practical. It keeps the machine, water, fuel, and tools together as a single self contained unit, so the job starts the moment you arrive rather than after a long setup. Trailer mounted pressure cleaners and ready made power wash trailers for sale are built for exactly this kind of work, with tanks, hose reels, and space for accessories already in place. For any operator planning regular commercial cleaning, a trailer is an investment that repays itself quickly.
Final Thoughts
Parking lots are a serious cleaning job, and they reward a serious setup. The heavy, oily soil and the sheer area involved mean that a light machine and a wand will not do; what is needed is a commercial pressure washer for parking lot work, with strong flow, adequate pressure, usually heat, and the duty cycle to keep going for hours. Added to that are the methods that make the work professional: surface cleaners for even coverage, a planned water supply, responsible handling of runoff, and a schedule that fits around the client’s day. Get these right and a car park becomes a routine job that a business can deliver reliably and profitably, time after time. The machine is the foundation, but the method, the planning, and the care taken with runoff and safety are what turn a good machine into a service a client will keep hiring.
Buy for the work and run it like a business. Choose a machine that matches your biggest and dirtiest lots, add heat if oil is a regular feature, and support it with good tools, a reliable water supply, and responsible runoff handling. Price the work to cover the machine, the fuel, the labour, and the compliance, with a fair margin, and keep the equipment well maintained so it never lets you down. Looked at this way, a pressure washer for parking lot cleaning is not simply a tool but the foundation of a business, and the machine, the method, and the discipline together are what turn a grimy slab of concrete into a clean, safe, professional result that keeps the contracts coming. Master the equipment and the routine once, and every lot after that becomes easier, faster, and more profitable than the last. In the end, success on parking lots comes down to matching good machines with good habits, and then repeating both every single working day. That simple discipline is the real secret behind every clean, profitable car park.
