Job clip: arriving on Lake Pointe Lane in Ann Arbor, with a single test pass already showing against the untreated slab.

Poured concrete driveways in south Ann Arbor take a beating once the fall leaves start dropping. On this residential job along Lake Pointe Lane in the 48108 ZIP code, the homeowner’s wide multi-slab concrete driveway, side turnaround pad, and curved front walkway had developed a dark layer of embedded organic grime, green algae, and brown leaf tannin stains. Because the turnaround pad sits beside a fenced garden bed and a portable basketball hoop base that holds moisture against the slab, the concrete had turned dark gray and slick underfoot.

Many homeowners try to tackle concrete staining with a consumer pressure washer and a narrow wand tip. On a wide residential driveway, a hand wand almost always leaves zebra striping and can etch the cream layer right off the concrete, especially around sealed expansion joints and repaired crack lines.

To clean the slab evenly without disturbing the joint sealant, our crew started by applying a biodegradable sodium hypochlorite and surfactant pre-treatment across the driveway apron, turnaround pad, and front walk. Giving the solution ten minutes of dwell time breaks down the root structure of the algae and lifts the leaf tannins out of the concrete pores before any pressure touches the surface.

Once the organic buildup loosened, we ran our commercial rotary surface cleaner, fed from the rig at the curb. A shrouded rotary bar keeps nozzle height and water pressure uniform across every pass, lifting years of tire-track film and biological growth in clean, overlapping lanes. Around the expansion joints, garden edging, and brick front steps, we switched to a controlled fan rinse to flush the loosened silt down the grade toward the street without splashing the hosta beds or siding.

The finished driveway and walkway dried to a bright, uniform aggregate tone from the garage apron all the way to the curb.
