El Dorado Business Park is concrete that gets driven on, not walked on. Loading aprons, dumpster pads and entry walkways off Lanark and Records Way take delivery-truck tire marks, hydraulic drips and winter deicer, and most of it was poured broom-finish and never sealed. That changes what pressure actually gets out.
Most of the concrete in El Dorado Business Park sees box trucks and delivery vans, not minivans, and it shows up differently than a residential driveway does. Tire scuff from tight turning radiuses prints black arcs into the broom finish behind the buildings. Hydraulic and gear oil collects where trailers sit. The slabs are almost always unsealed, so whatever lands on them soaks in instead of beading on top. We run a surface cleaner on flatwork rather than a bare wand, because a wand held close on unsealed commercial concrete leaves striping you can read from across the lot years later. Wands are for edges, curb faces and the first foot off a building — not for the middle of an apron.
Almost everything we pull off concrete in this park comes from one of four places. Petroleum — hydraulic fluid, motor oil, transmission drip — concentrated at loading positions and the first stalls of each row. Grease and food waste around dumpster enclosures, which spreads into a black sheen once the pad heats up. Winter deicer and cinder grit tracked in off Eagle Road and Overland, leaving a grey haze and, over several seasons, surface scaling. And rust rundown: orange streaks below steel bollards, downspout straps and railing anchors. Each one wants different chemistry laid down ahead of the water. Hitting all four with the same hot rinse is how you end up with a pad that came out clean in patches.
Pressure removes what is sitting on the surface. It does not remove what has soaked in. An oil drip that has been on unsealed concrete through a summer has wicked into the pores, and high pressure just lifts the top skin — the shadow returns as the slab dries out. That one needs a degreaser given real dwell time, sometimes two applications, and even then an old spot usually lightens rather than vanishes. Same story with concrete already scaled from deicer: washing does not repair it, it uncovers it, and the pad looks rougher for a week until it weathers back in. We will tell you which of those you have standing on the slab, before we quote it. Paying for a wash that cannot fix the problem helps nobody.
A lot of the pad and walkway concrete around this park is newer than the buildings it serves — poured during tenant improvements, lot expansions and pad additions. New concrete does two things worth knowing about. It blooms efflorescence, a white chalky mineral haze that rises out of the slab while it cures. That is salt, not dirt. Pressure knocks it down and it comes back until the slab stops giving it up, so it is usually worth waiting rather than paying to chase it twice. And fresh concrete is soft. We do not put a surface cleaner on a slab younger than roughly 60 days, because you will cut the cream layer and leave a permanent pattern. If your pour is recent, give us the date and we will schedule around it.
Pressure washing runs $0.20 a square foot on driveways, aprons, patios and walkways, measured off the actual area we clean. We walk the lot with you and give a firm number before anyone pulls a hose. Because the park runs on tenant hours, we schedule around them — early mornings and evenings, so a surface cleaner is not running past a lobby door or sitting in a loading position during a delivery window. Memberships come Monthly or Quarterly with no contract, which suits entry walkways and dumpster pads that go bad on a predictable cycle. We usually have same-day and next-day slots.

Usually we lighten them a lot, not erase them. On unsealed concrete the oil has soaked below the surface, so pressure alone only takes the top layer and the shadow reappears as it dries. A degreaser with proper dwell time, sometimes applied twice, does the real work. Fresh drips often come out completely. Multi-year spots we quote as an improvement, and we say so up front rather than after.
Give it about 60 days before we put a surface cleaner on it. Concrete keeps hardening well past the day it is walked on, and a machine run over a green slab can cut the cream layer and leave a swirl or track pattern you cannot undo. If a new pad needs construction dirt off sooner, we can rinse at reduced pressure instead. Tell us the pour date when you call.
That is efflorescence — mineral salts migrating out of the slab as it cures. It is not dirt, and it is not a mistake anyone made. Pressure will knock it down, but it comes back until the concrete stops pushing salt to the surface, which can take a season or more. We will tell you if what you are looking at is efflorescence so you are not paying to clean the same haze twice.
Yes, that is the normal way we run a job here. We work in sections so a dock stays usable, and we schedule early mornings or evenings around your delivery windows and tenant traffic. Tell us which positions cannot be blocked and when your trucks come. Water and runoff get directed away from doorways and drive lanes so nobody walks through a wet apron mid-shift.
No, and it will look worse before it looks better. Deicer and freeze-thaw cause surface scaling, and washing lifts the loose material that was hiding the damage. The pad reads rougher for a week or two, then weathers in. Cleaning is still worth doing on scaled concrete, but it is a cleaning, not a repair. We will point out the scaled sections during the walkthrough so it is not a surprise.
We measure the actual area being cleaned, not the whole lot. Aprons, walkways, entry pads, dumpster enclosures and any patio or seating concrete get measured separately at $0.20 a square foot, and you get a firm number before we start. If it makes more sense to clean the entries quarterly and the back-of-building flatwork once a year, we will price it that way. Call (208) 453-6760.
