Benton sits north of Bossier City as the parish seat, and the driveways up here are a different animal from what we clean down in town. The newer subdivisions off Highway 3 and the places out toward Cypress Black Bayou were built on big lots, so you get long runs of concrete, a wide apron in front of the garage, and a turnaround that half the family never even uses. All that square footage sits under pine and oak that hangs right over the slab, and the Gulf humidity keeps it damp for most of the year. Concrete in that situation does not stay one color on its own. It goes blotchy in bands, and the bands follow the shade line.

Most of what darkens a Benton driveway is organic. Green and black growth takes hold anywhere the sun never quite reaches by midafternoon, usually the north edge and everything under the canopy. Oak leaves and pine needles that sit through a wet week leave a tannin stain shaped like the pile that made it. Then there is the red clay, tracked in off an unpaved edge, off a neighbor’s lot still under construction, or straight off your tires after a hard rain. Add the tire marks where you back in, rust bleeding out from an irrigation head or a mower left parked in one spot, and the oil shadow where the truck always sits, and one slab is carrying five or six separate problems.

We clean with a flat-surface cleaner rather than a wand, and that one choice is the whole reason the finish comes out even. A surface cleaner rides on the concrete and spins two jets at a fixed height, so every square inch gets the same distance and the same dwell. A wand waved by hand cannot do that. It cuts a bright arc where it lands and leaves a shadow beside it, and on a long Benton drive you end up with zebra striping that catches the eye worse than the dirt did. We save the wand for edges, steps, and the seam along the garage where the machine cannot reach.

Oil is the one stain that pressure by itself will not fix. A cold rinse pushes the surface film around and leaves the rest sitting down in the pores, which is why the spot you hosed off in May is back by June. We put down a degreaser and give it time to dwell so it can lift the oil up out of the concrete, then work it with hot water. Heat thins the oil and lets it release instead of clinging. Fresh drips usually come out entirely. A spot that has been soaking in for years will often lighten to where you stop noticing it, and we will tell you which one you have before we start rather than after.
