Concrete Cleaning in New Baltimore
Concrete here dries last. The lake plain under the city is flat, it sheds slowly toward the bay, and a driveway that holds a damp film half the morning grows the same green a north wall does, except underfoot where it turns slick.
Three things sit on a drive in this city, and they do not come off the same way. The first is organic: the green and black film that builds where a slab stays wet, heaviest on walks shaded by full-grown trees and along the strip beside the garage that never sees afternoon sun. The second is traffic residue, the oil drip under the parking spot and the gray grime that blows in from 23 Mile Rd and M-29. The third is mineral: the rust arc a sprinkler head paints across a slab every summer, and the salt and grit brought home on tires through the winter.
Drainage sets the pace for all of it. The ground here is a flat lake plain, and runoff crosses the city through Marsac and Crapeau Creeks on its way to Lake St. Clair rather than dropping away through the soil under your slab. Water stands longer on flat sections and at the apron, and standing water is what feeds the film. Older flatwork on the downtown grid has been through decades of that and has a softer, more open surface. The concrete poured with the 2000s subdivisions is still tight, and it cleans up closer to new.
Cleaning starts at $149 for a standard driveway, and walks, aprons, porches and patios are quoted per section so you can take them together or take the drive alone. The work is done with a surface cleaner for an even finish, edges and expansion joints detailed by hand, and the rinse directed away from beds and the storm drain at the curb. If sealing is the plan, cleaning is step one, and the slab has to dry fully before anything protective goes down.
A Surface Cleaner, Not a Wand
The slab gets pre-treated first so the organic layer is dead before any water touches it, which is what keeps the clean even instead of blotchy. Then a surface cleaner does the open field: two jets spinning under a hood at a fixed height, so every square inch takes the same pass and nothing gets striped. Edges, the apron, expansion joints and the seam against the garage are detailed by hand. Oil is pulled with a degreaser and time, not more pressure, and rust from a sprinkler head takes its own chemistry. The slurry is rinsed off before it can dry back onto the surface, and downspout splash areas get a last pass.
Stripes, Etching and Dried Slurry
A wand swung by hand across an open slab leaves zebra stripes, and they are permanent in the sense that the only fix is cleaning the rest of the concrete down to match. Held too close, the same tip etches, and it etches fastest on older downtown flatwork where the surface paste has already weathered open. Skipping the pre-treatment produces a drive that looks clean wet and shows a shadow of the old pattern once it dries. So does leaving the slurry to dry where it lands, which sets a gray tide line across the apron.
Timing It Right
April through October is the working season, and early spring is the best single time, because a wash then lifts the winter load of salt and grit before it sits in the pores through a warm month. Shaded walks near the water are worth a mid-season pass, since that is where the film comes back first. Fall works too, particularly if sealing is on the calendar and you want the slab protected before freeze and thaw start again.

Concrete Cleaning in New Baltimore: FAQs
What does it cost to clean a driveway here?
From $149 for a standard drive, with square footage and how much is growing on it moving the number. A long subdivision drive with a wide apron and a walk to the porch runs above the starting figure. Walks, patios and porches are quoted per section, and taking them on the same visit as the drive costs less than a second trip.
Will cleaning take out the rust line my sprinkler leaves?
Usually most of it. Sprinkler rust is iron staining sitting in the top of the slab, and it responds to a rust-specific treatment rather than pressure, which only polishes it. Fresh arcs lift far more completely than ones that have been baking in for several summers. We treat it as a separate line on the quote because it takes separate product and time.
My concrete is green and slippery along one side. Why only there?
That strip stays wet longer than the rest. Shade from a tree, a garage wall or the house itself keeps the sun off it, and on ground this flat the water has nowhere to go quickly. Algae grows anywhere that stays damp, and on a horizontal surface it also gets slick. Killing it rather than rinsing it is what keeps it from returning by August.
Is pressure washing going to damage older concrete downtown?
Not the way we run it. Older slabs have an open, weathered surface, so they get a longer chemical dwell and a lighter, evenly moving pass rather than a close-held wand. Where the paste has already spalled or the aggregate is showing, cleaning will not hide it, and we say so before quoting so the result is no surprise.
